Rubi Trowels
Rubi trowel range gives tilers the right spread, notch and finish for bedding tiles properly and keeping adhesive coverage consistent on site.
If tiles are rocking, coverage is patchy, or you're forever scraping dried adhesive off the face, start with the trowel. A proper Rubi trowel or Rubi notched trowel lays adhesive evenly, keeps bed depth consistent, and helps you work faster without making a mess of the set-out. From wall tiling and big floor formats to grout finishing, this is the sort of kit tilers keep close because it saves rework. You will also find the rest of the Rubi Tools range here, ready to sort the full job.
What Are Rubi Trowels Used For?
- Spreading tile adhesive across walls and floors with a Rubi adhesive trowel gives you an even bed, which matters when you are setting porcelain or large format tiles that do not forgive hollow spots.
- Using a Rubi notched trowel to comb adhesive in straight lines helps collapse the ridges properly when the tile is pressed in, giving better coverage and fewer drummy tiles later on.
- Setting bathroom, kitchen and utility wall tiles with the right notch size keeps adhesive under control, so you are not fighting squeeze-out round every spacer and trim.
- Working on bigger floor areas with a Rubi square notch trowel makes it easier to hold a consistent bed depth, especially when you are trying to keep level across awkward substrates.
- Finishing joints with a Rubi grouting trowel helps force grout properly into the lines without dragging half of it straight back out again.
Choosing the Right Rubi Trowel
Sorting the right Rubi trowel is simple. Match the notch and blade to the tile, adhesive and area you are actually laying.
1. Match the Notch to the Tile Size
If you are fixing small wall tiles, do not go too big on the notch or you will spend half the day cleaning squeeze-out. If you are laying larger floor tiles or porcelain, step up to a bigger notch such as a Rubi 10mm notched trowel so you get the coverage you need underneath.
2. Square Notch or V Notch
If you need more adhesive volume under larger tiles, a Rubi square notch trowel is usually the better shout. If you are on lighter wall work or smaller formats, a V-notch can help keep the bed neater and easier to control.
3. Stainless Blade Matters
If you are using these day in, day out with cement-based adhesives and grout, buy stainless where possible. It cleans up better, resists rust, and does not leave you fighting a rough blade edge halfway through a job.
4. Buy a Set if You Do Mixed Tiling Work
If one week you are on splashbacks and the next on big kitchen floors, a Rubi trowel set makes more sense than trying to make one notch do everything. It saves bodging the spread and gives you the right option in the van.
Who Uses These on Site?
- Wall and floor tilers are the obvious ones, because a good Rubi tiling trowel helps them keep adhesive coverage right on first pass rather than lifting tiles to fix missed spots.
- Bathroom fitters and kitchen installers reach for these when setting splashbacks, wet room walls and floors, where the right Rubi 10mm notched trowel can make the difference between a clean lay and a fight.
- General builders doing refurbs use a Rubi trowel set when they need one lot of kit to handle small wall tiles, larger floor tiles and grouting without guessing their way through the job.
- Maintenance teams and property renovators keep them handy for repair work, replacement tiles and patch jobs, especially where matching bed depth to the existing finish matters.
The Basics: Understanding Tiling Trowels
Tiling trowels are not complicated, but the notch shape and size directly affect how much adhesive stays on the floor or wall. Get that wrong and you will feel it when tiles sit uneven, sound hollow or need lifting.
1. The Notch Controls Adhesive Depth
A notched blade leaves ridges of adhesive at a set height. Once the tile is bedded in, those ridges collapse to give you the coverage needed underneath, which is what keeps the tile properly supported.
2. Bigger Tiles Need More Coverage
Larger and heavier tiles usually need a bigger notch because they need more adhesive beneath them. That is why a Rubi adhesive trowel for wall tiles is often smaller than the one you would use on a large floor porcelain.
3. Grouting Trowels Do a Different Job
A Rubi grouting trowel is for pushing grout into joints cleanly and evenly. It is about filling lines properly without dragging material back out, not combing adhesive for bedding tiles.
Rubi Accessories That Help You Finish the Tiling Job Properly
A trowel gets the adhesive down, but these are the extras that stop the rest of the job turning into hard work.
1. Rubi Paddle Mixers
Get the mix right before the trowel even touches the floor. Rubi Paddle Mixers help you avoid dry pockets, weak adhesive and lumps that drag through the notch and ruin the bed.
2. Rubi Tile Vibrators
If you are laying larger format tiles, Rubi Tile Vibrators help settle the tile into the adhesive bed and collapse ridges properly. That saves lifting corners to check coverage every five minutes.
3. Rubi Vacuum Lifters
For heavy porcelain and awkward large format pieces, Rubi Vacuum Lifters make positioning safer and cleaner. You get the tile down where you want it without shuffling it across the adhesive and spoiling the spread.
4. Rubi Tiling Tools
A trowel is only one part of the process. The wider Rubi Tiling Tools range covers the rest, so you are not stuck halfway through a job missing the one bit of kit that keeps the work moving.
Choose the Right Rubi Trowel for the Job
Use this as a quick guide before you pick your notch.
| Your Job | Category or Type | Key Features |
|---|---|---|
| Small wall tiles and splashbacks | Rubi adhesive trowel with smaller notch | Better control, less squeeze-out, easier to keep joints clean |
| Standard bathroom and kitchen wall tiling | Rubi notched trowel | Even adhesive combing, reliable bed depth, good coverage on regular tile sizes |
| Large format floor tiles | Rubi square notch trowel | Higher adhesive build, stronger support under bigger tiles, more consistent bedding |
| Porcelain floor work needing fuller coverage | Rubi 10mm notched trowel | Deeper ridges, better contact under heavy tiles, suited to larger formats |
| Pointing and finishing grout joints | Rubi grouting trowel | Pushes grout firmly into joints, cleaner finish, less drag across the face |
Common Buying and Usage Mistakes
- Buying one notch size for every job is the usual mistake. Small wall tiles and large floor porcelain do not want the same adhesive bed, so match the trowel to the tile or expect poor coverage and extra clean-up.
- Using a worn notch and hoping for the best gives you inconsistent ridge height. Once the edges round off, the adhesive bed changes and so does the support under the tile, so replace it before it causes drummy spots.
- Letting adhesive dry on the blade after every shift shortens the life of the trowel and ruins the spread. Wash it off while it is still workable and the notch will stay clean and accurate.
- Picking a grouting trowel for adhesive work, or the other way round, just slows the job down. Each tool is shaped for a different task, so use the proper blade for bedding tiles and the proper face for joints.
- Ignoring tile size and substrate flatness can leave you blaming the adhesive when the real issue is tool choice. If the floor is uneven or the tile is large, step up the notch and check coverage properly as you go.
Square Notch vs V Notch vs Grouting Trowel
Square Notch
This is usually the one for larger tiles and floor work because it leaves more adhesive behind. If you need stronger bedding and fuller coverage under porcelain, this is the sensible choice.
V Notch
V-notch trowels suit lighter adhesive application and smaller formats where you want control more than volume. Good for neat wall work, but not the one to force onto big floor tiles.
Adhesive Trowel
A Rubi adhesive trowel is your bedding tool. The important bit is matching the notch size and shape to the tile, because that decides coverage, squeeze-out and how flat the finished work sits.
Grouting Trowel
This is for finishing joints after the tiles are set. It is not there to spread adhesive, but to force grout into the lines cleanly and help leave a tidier final finish.
Maintenance and Care
Clean It Before the Adhesive Goes Off
Do not leave tile adhesive to set on the blade overnight. A quick rinse and scrape while it is still fresh saves a lot of grief and keeps the notch profile working as it should.
Check the Notches for Wear
If the teeth are rounded or uneven, the trowel is no longer laying the adhesive depth you think it is. Once that happens, retire it from critical tiling work.
Store Blades Flat and Dry
Chuck a trowel loose under heavy kit in the van and the blade can bend. Keep it dry and laid flat so the edge stays straight and ready for the next job.
Do Not Use Damaged Edges for Finish Work
A nicked or burred blade drags through adhesive and leaves a messy comb. Fine for rough patching maybe, but not for neat wall tiling where coverage and finish matter.
Replace When Accuracy Drops Off
Trowels are consumable site kit in the end. If it no longer spreads cleanly, holds a straight edge or leaves consistent ridges, replace it rather than risking a failed tile bed.

Rubi Trowel FAQs
What notch size trowel should I use for floor tiles?
For floor tiles, it depends mainly on tile size and how flat the floor is. Smaller floor tiles can use a smaller notch, but larger porcelain often wants something like a Rubi 10mm notched trowel to get proper coverage. The honest answer is do not guess. Bed a tile, lift it, and check the adhesive is spreading properly underneath.
What's the difference between square and V-notch trowels?
Square notch trowels leave more adhesive behind, so they are usually better for larger tiles and floor work. V-notch trowels lay a lighter bed and are often easier to manage on smaller wall tiles. If you need more support under the tile, square notch is normally the safer bet.
Are Rubi trowels stainless steel?
Many Rubi trowels use stainless steel blades, which is exactly what you want for regular adhesive and grout work because they resist rust and clean up better. That said, always check the individual product spec, because not every trowel in a wider range is identical.
What notch size should I use for wall tiles?
Wall tiles usually take a smaller notch than floor tiles, especially on standard bathroom and kitchen work where too much adhesive just squeezes into the joints. Match the notch to the tile size and weight, then check coverage by lifting a tile early on rather than finding out later it has only caught on the high spots.
How do you clean a trowel after using tile adhesive?
Best way is straight after use, before the adhesive hardens. Wash the blade in clean water, use a stiff brush or scraper to clear the notches, and dry it off before it goes back in the van. Leave adhesive on overnight and you will spend longer chipping it off than you did laying the tiles.
Do I really need more than one tiling trowel?
Yes, if you do mixed tiling work. One trowel will not suit splashbacks, standard wall tiles, large floor porcelain and grout finishing equally well. A couple of notch sizes plus a grouting trowel will cover most real site jobs properly.
