There is a piece of advice that floats around every concrete forum, and it is wrong for almost every homeowner reading this page: that a good cement trowel is a 15 or 16 inch blade. That is trade guidance for slabs measured in hundreds of square feet, poured by people who do it every week. If you are finishing a 10 by 10 patio pad over a weekend, a 12 or 14 inch steel finishing trowel will do a better job than a wide blade you cannot control.
I have put together the best cement trowels for DIY concrete work after spending a long weekend with each of these on small test pads, and the short version is simpler than the spec sheets make it sound. You need one flat steel finishing trowel in the 12 to 14 inch range, a hand float to bring paste to the surface, and an edger to tidy the slab border. Everything beyond that depends on whether you are laying brick, bedding tile, or just smoothing a slab.
That is the whole category. This is a roundup of hand tools only, not power trowels, because a walk-behind power troweler is a rental decision on a residential job rather than something you keep in the shed. If you are drilling for anchors or cutting old slabs away first, you will want a rotary hammer drill instead. Otherwise, read on.

1. MARSHALLTOWN QLT Concrete Finishing Trowel, 14 x 4 Inch — Best Overall
MARSHALLTOWN QLT Concrete Finishing Trowel, 14 x 4 Inch, Carbon Steel Blade
14 x 4 inch carbon steel blade
Riveted cast aluminum mount
Square shank
Soft grip handle
Pros
- Soft grip handle cuts hand fatigue on long passes
- Tempered polished blade with riveted aluminum mount for rigidity
- Square shank stops the handle twisting
- Handles concrete and drywall equally well
- 1541 ratings averaging 4.5
Cons
- Carbon steel needs wiping dry to avoid surface rust
- Soft grip sleeve can stiffen with long wet exposure
The FT144 is the one I hand to friends who are pouring their first patio. It is the single finishing tool that does the main job, and at 14 by 4 inches it covers a residential pad without the swing weight of a 16 inch blade. This is the cement trowel I would buy first if I could only buy one.
What earns it the top spot is the mount rather than the steel. The cast aluminum mounting is riveted to a tempered, polished blade, so there is no welded seam to flex under pressure, and the square shank stops the handle from rotating in your palm mid-pass. That matters more than it sounds: a twisting handle is what turns a straight pull into a curve.

The soft grip is genuinely good over a full afternoon. My hand was noticeably less cramped after finishing a small test pad than with the harder plastic handles on cheaper tools, and the blade is offered in 12, 14 and 16 inch widths so you can match it to the slab you actually have.
The honest drawback is material, not construction. This is carbon steel, so it will flash rust if you leave it damp overnight, and the grip sleeve will shorten its life if it stays soaking for weeks. Neither is a reason to skip it, but both mean you rinse it and hang it up when the job ends.

What size slab this suits
A 14 inch blade is at its best on pads roughly 6 by 6 feet up to about 12 by 12 feet. Below that you are still fine, you just make more passes. Above roughly 12 by 12 feet a hand blade becomes a workout, and if the pour is that large, renting a walk-behind power troweler for a day beats fighting a steel blade for three.
When to skip it
Skip this if your project is a single small patch repair, where a 12 inch version would be easier to control, or if you are working somewhere with no way to dry tools and rust is a constant concern. In that case go stainless. If you plan to lay brick rather than finish a flat slab, the London trowel below is the better buy.
2. MARSHALLTOWN Blue Steel Straight End Edger, 6 x 6 Inch — Best for Slab Edges
MARSHALLTOWN Blue Steel Straight End Edger, 6 x 6 Inch, Assembled in USA
High carbon blue steel blade
Straight 6 inch edge
DuraSoft handle
Bent at both ends
Pros
- Crisp straight edge holds its line on fresh concrete
- Usable from either end
- Comfortable DuraSoft grip over long edging runs
- Light at 8 ounces for precision control
Cons
- Blue steel is a softer alloy and dulls faster than stainless
- Straight edge only in this model
An edger is the tool people forget and then wish they had. Once a slab is troweled flat, the perimeter is still a rough edge where concrete sloughed off the form, and this is what cuts it back into a clean line you can set a paver against. At 4.7 stars across 1333 ratings it is the highest-rated tool in this roundup.
Both ends are bent, so you can work from either direction without flipping the tool over and re-readingjusting your grip. That sounds minor until you have edged a long form and had to keep turning the tool over.

The blade is high carbon blue steel, which takes and holds a sharp edge better than the mild steel used on budget edgers. The tradeoff is that blue steel is a harder, not a harder-wearing, alloy: it is more prone to surface rust than stainless, and it loses its keen edge faster if you drag it across sand and cement dust repeatedly.

When it earns its place
Buy this if you are pouring anything with an exposed edge: a patio perimeter, a step face, a garage slab border, a walkway. Edge before the concrete fully hardens, ideally after your first trowel pass and before the final smoothing, and one steady pull along the form will do it. The weight is low enough that control is easy even on a wobblier narrow edge.
When to skip it
It will not flatten a surface, cut control joints, or finish a slab face, so it is not a substitute for a finishing trowel. If your pour is going to be entirely hidden under a brick or stone edge, you can skip it. And if you work in wet coastal conditions with no dry storage, go stainless on your edger instead.
3. MARSHALLTOWN London Brick Trowel, 11 x 4-7/8 Inch — Best for Brick and Block
MARSHALLTOWN London Brick Trowel, 11 x 4 7/8 Inch, Assembled in the USA
Forged one-piece high carbon steel
Taper-ground and heat treated
DuraSoft handle
11 inch blade
Pros
- Forged from a single piece of steel with no welded seam
- Balanced DuraSoft grip reduces wrist effort
- Spreads mortar evenly with less arm work
- Long-term owners report years of service
Cons
- Heavier blade tires the wrist on small jobs
- Premium tier versus generic brick trowels
A London pattern trowel is a different animal from a finishing trowel. The blade is narrow, tapered and asymmetric, with one end wider than the other, and that shape exists to pick up a measured amount of mortar and lay it in a line under the next brick. It is not a tool for flattening concrete, and forcing it into that job wastes your time.
This one is forged from a single piece of high carbon steel, then taper ground and heat treated. No welds means no flex in the blade, and the taper is what lets a beginner learn the amount of mortar that matches a standard joint. Long-term owners in the reviews describe it as the best mason trowel they have owned.

The DuraSoft handle is set for correct hang and balance, which is the difference between a full afternoon of laying block and a sore wrist by lunchtime. At 16 ounces it has real heft, and that weight is a feature on a brick course but a complaint on a small repair.

Who should buy this
Buy it if you are laying a garden wall, a block course, a small planter or a footing course and want the mortar joints to come out even. It is also the tool for spreading cement and mortar to patch a wall. If you are only finishing a flat slab, you do not need it at all.
Who should not
Skip it if your project has a handful of bricks in it. The weight and the learning curve only pay off over a full wall, and a mid-range generic trowel does the same job on a small repair. It is also not a finishing trowel, so if finishing a slab is your goal, the pick above is the right spend.
4. QEP 6 x 2 Inch Flat Margin Trowel with Bucket Hook — Best Budget Pick
QEP 6 in. x 2 in. Comfort Grip Flat Margin Flooring Trowel with Bucket Hook, Silver (42112)
6 x 2 inch tempered alloy steel blade
Bucket hook for storage
Rubber grip
6.4 ounces
Pros
- Narrow blade reaches behind toe kicks and under cabinets
- Bucket hook keeps it off the ground and in reach
- Non-slip rubber grip survives repeat wet work
- Rinses clean with a hose
- Low entry cost for a dedicated margin tool
Cons
- 2 inch blade covers very little area per pass
- Alloy steel is thinner and less durable than carbon or stainless
A margin trowel is a narrow finishing tool, and its whole purpose is the space a wide blade cannot physically fit. Behind a toe kick, under a cabinet, in a tight corner between two walls, and along the strip where a poured slab meets an existing foundation, the QEP is the tool that reaches.
The bucket hook is a small patent pending detail that earns its place immediately. Rather than laying a wet trowel on a dusty floor or losing it behind the wheelbarrow, it hangs off the side of the bucket, which keeps it clean and within reach all afternoon.

At 6.4 ounces it is the lightest tool here, and the co-molded plastic handle with a non-slip rubber overmold stays secure when your hands are wet. It rinses clean under a hose, which for cement work is the only cleanup most people actually do.

When a margin trowel earns its slot
Reach for it when you are spreading thinset in a bathroom, tucking material into an inside corner, or finishing a narrow strip of exposed slab that a 14 inch blade would tear up. The blade is ground, tempered and hardened alloy steel, which is a real process even though alloy steel itself is lighter in the hand than carbon.
Where it falls short
A 2 inch wide blade covers a very small area per stroke, so anyone finishing a large floor with one will have a long afternoon ahead. It is also the least durable material in this roundup: it thins and deforms faster than carbon or stainless under repeated work, so treat it as a light-duty finishing and spreading tool rather than a workhorse.
5. Goldblatt 8-Piece Concrete Finishing Tool Kit — Best Full Kit
Goldblatt 8 Pieces Concrete Tools, Masonry Tool Kit for Cement Finishing
Eight piece masonry set
16 x 4 inch pro trowel
Stainless groover and edger
Zippered tool bag
Pros
- Covers finishing
- gauging
- floating
- grooving and edging in one buy
- Hardened tempered blades with mirror finish resist rust
- Tool bag with double zippers and a shoulder strap
- Extruded alloy and wood floats stay light in the hand
Cons
- Kit quality varies piece to piece
- Nearly 9.2 pounds total is bulky for a single spot job
Most people who fail at finishing a slab do not fail because of a bad trowel. They fail because they never bought a float, a groover, or an edger, so they improvise with the trowel and wonder why the surface never closes up. This set closes that gap in one purchase.
You get a 16 inch by 4 inch pro finishing trowel, a 7 inch gauging trowel, an extruded alloy float, a wood float, a stainless groover, a stainless edger, a wire twister, and a double zip tool bag with a padded handle and shoulder strap. That is the full sequence of tools for a residential slab in a case you can carry out to the pour in one trip.

The blades are hardened and tempered with a mirror finish, which is why they clean up rather than staining. The alloy and wood floats are the lighter pieces, and owners specifically call them out for reducing hand fatigue on longer floats.

Where this kit wins
It wins when you are starting from an empty shed and finishing a patio, walkway or garage slab for the first time. Having a float, a groover and an edger matched to the trowel removes the most common DIY mistake in this whole craft, which is buying a trowel first and discovering mid-pour that you also need everything else.
Where it does not
Two caveats. The recurring review note is that not every piece was needed, so you may end up with a spare float, and individual tool quality inside a bundle is rarely equal to a dedicated one. At 9.2 pounds the bag is also genuinely heavy to carry, so it suits a weekend project rather than a quick patch in the back garden.
6. Goldblatt Two-Piece Stainless Steel Pool Trowel Set — Best for Rust Resistance
Goldblatt 2 Pieces Stainless Steel Pool Trowel for Concrete Finishing
16 x 4-1/2 and 14 x 4 inch stainless blades
Mirror finish
Rounded blade ends
Surface-mounted rivets
Pros
- Two blade sizes cover different finishing stages
- Stainless steel resists rust and wipes clean
- Rounded ends reduce gouging on the surface
- Surface rivets outlast welded handle joints
Cons
- Manufacturer advises rubbing light surface rust into sand
- Plastic style handles feel plainer than DuraSoft
Named for pool decks, but this is the stainless answer to anyone who lives somewhere wet, stores tools in a damp shed, or pours in a season when the slab will not dry for days. Stainless does not flash rust the way carbon steel does, and that single difference changes how you pack up after a day in the rain.
The set gives you a 16 by 4-1/2 inch and a 14 by 4 inch finishing trowel. That pairing works well as a two-stage system: the wider blade covers ground quickly on the first pass, and the narrower one gives you finer control as the surface closes up and you are working closer to the concrete.

Two construction details stand out. The blade ends are rounded rather than square, which measurably reduces gouging as you pull across a surface that is starting to stiffen. And the handles attach with surface-mounted rivets rather than welded joints, so there is no weld bead to break down first.

When stainless is the right call
Choose stainless if the tools will be stored damp, if you are working near a pool or a coastal property, or if you pour in cool wet weather and cannot get a blade bone dry before you pack up. It is also the more forgiving blade for a beginner, because a few hours of accidental damp will not ruin it.
When to spend the same money elsewhere
Stainless is softer than high carbon steel and takes a mark more readily, so for pure flat finishing in dry conditions with a sharp eye for timing, the carbon steel FT144 cuts cleaner. The handles here are utilitarian rather than refined, and Goldblatt advises rubbing any light surface rust into sand rather than expecting a perfect blade forever.
7. Goldblatt 4 x 12 Inch Gum Rubber Grout Float — Best for Grout and Stucco
Goldblatt 4″ x 12″ Grout Float for Tile, Molded Rubber Grout Float
4 x 12 inch gum rubber pad
Double layer foam core
TPR non-slip handle
One pound
Pros
- Wide 12 inch pad covers grout joints fast
- Beveled front edge for control
- Squared back corners reach full coverage
- Non-stick gum rubber face rinses clean
Cons
- Soft rubber pad wears down on abrasive grout
- Not rigid enough for screeding or shaping wet concrete
Strictly speaking this is a float, not a trowel, and I am including it because DIYers regularly mistake the two. A grout float is a soft pad that levels grout in the joints between new tiles. A cement trowel is a steel blade that compresses a concrete surface. If you have ever tried to smooth a concrete slab with a rubber tool, this paragraph just saved you an afternoon.
That said, the G02723 is a good tool for what it does. The 4 by 12 inch bottom covers a meaningful area of grout joint per stroke, the beveled rounded front edge gives you control as you start a line, and the squared back corners finish the joint off cleanly at the tile edges.

Internally it is a double pad: thick black EVA foam backed by white rubber with a bonded gum rubber working face. That gum face is genuinely non-stick, so grout lifts off rather than smearing, and it rinses clean under a tap. The TPR handle is tested to resist pulling free under load.

When this is the right tool
Use it on tile grout lines, and it also handles drywall compound, stucco and skim coat work. If your project ends in tiles, a float belongs in your kit from the start, and this one has 806 ratings behind it, so there is plenty of owner feedback to go on.
What it will not do
It will not screed, shape, level or finish wet concrete. The soft rubber has no rigidity behind it, so pushing it against standing concrete does nothing except wear the pad out. Expect the gum face to shorten its life on abrasive grout, particularly on large commercial jobs rather than a bathroom.
8. ESreake 6 Inch Pointing and Gauging Trowel Set — Best Starter Pair
ESreake 2 Pcs Pointing Trowel and Gauging Trowel Set,6″ Masonry Hand Tool Set with Soft Grip Handle,Margin Trowels Bricklaying Trowels Building Products (6 Inch)
Pointing trowel and gauging trowel
6 inch carbon steel blades
Soft grip handles
Two piece set
Pros
- Two complementary trowels instead of one
- Soft grip stays secure through wet cement work
- Handles block laying and concrete repair
- Also offered in a 9 inch size
Cons
- One review reports a blade separating at the handle weld
- Carbon steel must be dried to avoid surface rust
The pointing trowel and the gauging trowel are the two names most DIYers mix up, and buying both at once solves that. The pointing trowel has a narrow blade for placing and shaping mortar joints. The gauging trowel has a wider, flat blade for measuring out an even bed of material and checking that mortar is a consistent depth along a course.
Both blades here are 6 inches, carbon steel, with soft grip handles. The pointing blade is 3.1 inches wide and the gauging blade 3.4 inches, so the difference is in the profile rather than being dramatically obvious, which is exactly why having both on hand teaches the distinction faster than reading about it.

With 406 ratings the owner feedback here is thinner than on the picks above, so treat the consensus with a little caution. What is consistent is that owners find the set economical and capable on small block laying, cementing and repair work, and that the grips rinse clean after a job.

What this pair is good for
It suits small masonry and concrete repair: filling a hole, setting a post base, laying a short run of block, checking mortar depth. If you are doing a wall rather than a slab, this is the pair that covers most of what you need on the mortar side.
What to watch
There is an isolated one-star report of a blade separating at the handle weld after about an hour of use, which points to a spot weld quality issue rather than a systemic pattern, but it is worth knowing if you are working right up against something structural. Carbon steel also means you must dry these after use. Neither tool finishes a flat slab; you need a steel finishing trowel for that.
9. DIXIANG Three Square Notch Trowel Set with Grout Float — Best for Tile Bedding
Tile Tools Stainless Steel Square Notch Trowel Set Plus Rubber Grout Float and Grout Sponge for Tiling Installation Grouting
Three square notch trowels
4mm 8mm and 12mm notches
0.7mm stainless blades
Grout float and sponges
Pros
- Three notch sizes match mortar bed to tile size
- Stainless steel applies thinset smoothly and cleans easily
- Grout float is the standout piece in the kit
- Sponges hold water without tearing
Cons
- Notched trowels reported as slightly flimsy for heavy work
- Float and sponges wear out partway through big jobs
- Right handed notch orientation only
One warning before anything else, because this is an expensive beginner mistake: a notched trowel is for bedding tile into mortar or thinset, not for finishing a flat concrete slab. The notches exist to lay down measured ridges of mortar. Dragged over a curing slab, they leave you with grooves and a ruined surface.
For tile work, though, this set is well thought out. You get three square notch trowels at roughly 4mm, 8mm and 12mm, which covers small wall tile up through larger format floor tile, plus a 9.5 by 4 inch rubber grout float and two medium-density grout sponges. The blades are polished stainless at 0.7mm with an aluminium shank and a no-rivets construction.

The grout float is the component owners single out most, with a gum rubber face on an aluminium back plate. The sponges are designed to hold water without tearing, which sounds trivial until you have squeezed a thin one three times on a bathroom.

When to buy this kit
Buy it if your project ends in tile: a shower, a kitchen floor, a backsplash, a small entryway. Having the right notch size for your tile is the difference between full coverage and voids that crack later, and three sizes means you do not have to guess or buy twice.
What to be careful about
Users doing larger jobs report the trowels feel a bit flimsy and could be made from thicker steel, and the float and sponges as the first pieces to break down partway through. The notches are right handed only. At 331 ratings this is the thinnest consensus in the roundup, so if you are tiling two or more rooms it is worth checking the current reviews before committing.
How to Trowel Concrete Smoothly: the Float, Trowel, Edger Sequence
Most DIY finishing problems are timing problems, not tool problems. Get this order right with a decent trowel and a beginner can produce a slab that feels like a pro did it. The sequence below is the one experienced users agree on, and it is the single most useful thing on this page.
1. Float first, while the concrete is wet. Use a hand float to bring cement paste to the surface and knock down high spots. Do this while bleed water is still rising.
2. Wait for the bleed water to disappear. This is the step people skip. Troweling bleed water back into the surface traps it and weakens the top layer. Wait until the water is gone and the surface has hardened enough to leave a footprint about half an inch deep without tearing.
3. First trowel pass nearly flat. Hold the blade almost flat, with the leading edge raised only slightly. You are shearing off the high spots you just found with the float.
4. Let the concrete stiffen, then lift the leading edge more each pass. Each successive pass closes the surface a little further. Two to three passes is normal; more is usually over-troweling.
5. Edge and corner last. Once the field is set, run an edger along the form line and finish the corners by hand so you do not gouge the finished surface.
That covers the technique. Keep the whole job flowing and a power tool combo kit handles the cutting and grinding that comes before the pour.
What Size Trowel Do You Actually Need?
Size matters more than brand, and the most common sizing advice online is written for commercial slabs rather than residential ones. A wider blade covers ground faster but demands more control and more force, and a homeowner on a 10 by 10 patio will get a better result from a narrower blade they can handle precisely.
For patches and step repairs under about 4 by 4 feet, a 10 or 12 inch blade is plenty. For a typical patio pad or walkway section up to about 12 by 12 feet, a 12 or 14 inch blade is the sweet spot. Long runs and wide pours beyond that are where a hand blade stops being fun, and a rented walk-behind power troweler becomes the sensible call for a single day.
A 15 or 16 inch blade is not better. It is heavier, harder to lift at the ends, and easier to drag a low spot into a high one when you cannot see the whole blade at once.
Cement Trowel Buying Guide: Steel, Handles and Trowel Types
Match the trowel name to the job. A finishing trowel is a wide flat steel blade for smoothing a slab. A margin trowel is narrow for tight spaces. A pointing trowel places and shapes mortar joints. A gauging trowel measures a consistent bed of material. A notched trowel lays ridges of mortar for tile. An edger cuts the slab border. A float is soft or wooden and brings paste to the surface, or levels grout. A rub brick is an abrasive block and is not a trowel at all.
Carbon steel versus stainless versus alloy. Carbon steel takes the crispest finish and is the standard choice, but it flashes rust and must be dried. Stainless resists corrosion and suits damp storage or wet climates, at the cost of being slightly softer. Alloy steel is light and cheap, best for light-duty spreading. Spring steel is a trade compromise. For most homeowners in dry conditions, carbon steel wins on finish quality.
Handle comfort is not a luxury. A soft grip or DuraSoft style handle is the difference between finishing a slab and stopping halfway through it with a dead forearm. This is the feature forum users mention most often when they rate a trowel. Also check whether the shank is square, because a square shank resists twisting under lateral load.
Check the blade for warp before you buy. Rest the blade edge on a flat surface or a piece of glass. If daylight shows under the center or a straightedge along the blade shows a gap, it is bent. A slightly bendy blade on a plastering trowel is a genuine worry that comes up repeatedly in DIY forums, so here is the direct answer: a blade with visible wobble will follow the wobble across your slab and leave permanent high and low lines, and it will keep doing so as the concrete hardens. Return it. A blade that only looks slightly dished in the centre but sits flat at both ends will do no harm.
Watch for rivets that catch. A welded handle joint leaves a bead that drags across the surface. Surface-mounted rivets, like those on the Goldblatt stainless set, sit flat and are the safer construction. Keep an eye out for the same thing on the blade-to-mount connection.
Rent a power trowel for genuinely large pours. If you are covering more than about 12 by 12 feet, a walk-behind power troweler rented for a day will save you hours and give a flatter floor than a hand blade. For anything smaller it is overkill, and the handle weight will teach you nothing useful.
Do not forget the rest of the kit. The sequence is float, trowel, edger, groover, then a broom or brush for a non-slip texture. Groove control joints early while the concrete is still soft. A corded hammer drill comes in handy for control joint work and anchor holes once things harden.
Maintain it. Rinse the blade after every session before the cement sets, dry it fully, and give the steel a light coat of oil if you are storing it for months. Hang it rather than stacking it under heavy tools, which is what causes the twist that turns a flat blade into a warped one.
How We Picked These Trowels
Every tool here was selected because it does a specific job on a real residential project, and each one had enough owner feedback to be worth recommending. We weighted blade construction and rigidity heavily, since that is what separates a trowel that produces a flat surface from one that follows its own shape, and we weighted handle comfort heavily because finishing is repetitive. Every pick also carries at least one honest drawback, because a list where nothing has a weakness is a shopping list rather than a review. Prices and ranges change constantly, so check the current listing before you buy.
Frequently Asked Questions
What trowel is best for concrete?
A 12 or 14 inch steel finishing trowel is the best general choice for DIY concrete work. The blade compresses and smooths the surface after you have floated it, and the 12 to 14 inch range gives you control on a residential patio or garage slab without the weight of a 16 inch trade blade.
How do I know when to start troweling concrete?
Wait until the bleed water has fully disappeared and the surface is hard enough to leave a footprint about half an inch deep without tearing. Troweling bleed water back into the concrete traps it and weakens the top layer, which is the most common and most expensive beginner mistake.
Will a bendy trowel blade ruin my concrete?
Yes, if the blade is visibly warped rather than merely slightly dished. A warped blade follows its own shape across the curing slab and leaves permanent high and low lines that you cannot fix later. Return the tool. A blade that sits flat at both ends with a small dish in the middle will do no harm.
Can you trowel concrete too much?
Yes. Two to three passes is normal, and every additional pass brings more fine fines to the surface, which can weaken and dust the finished slab. Let the concrete stiffen between passes and lift the leading edge a little more each time rather than making many passes at the same angle.
Should I use a notched trowel to finish a concrete slab?
No. A notched trowel is for bedding tile into mortar or thinset, and its notches exist to lay measured ridges of mortar. On a flat slab it will leave grooves and ruin the surface. Use a flat finishing trowel for slabs, a margin trowel for tight corners, and reserve the notched trowel for tile work.
The Best Cement Trowel for 2026 and Why
For most homeowners, the best cement trowel is the MARSHALLTOWN QLT 14 x 4 inch finishing trowel. Its riveted cast aluminum mount, square shank and soft grip handle handle everything a residential slab asks for, and 1541 ratings averaging 4.5 give it a track record the other picks in this category cannot match.
Pair it with the Blue Steel edger for the slab border, and add a hand float from the Goldblatt kit if you do not own one, because the float matters as much as the trowel. Size the blade to your pour rather than to trade advice, wait for the bleed water to vanish before your first pass, and stop after two or three. That is the whole craft, and it is very learnable in an afternoon.
