How to Tile a Wall?

Let’s face it, mouldy bathroom tiles and cracked kitchen splashbacks are eyesores that are easy to ignore.

Tools needed:

  • Tile cutter
  • Tile spacers
  • Tile adhesive
  • Grout
  • Grinder
  • Trowel
  • Spirit level
  • Sponge

Step 1: Wall Preparation

The first order of business to installing fresh tiles is readying the surface. While it’s possible to tile over everything from cement to brick, failing to smooth out imperfections on the base layer will cause your adhesive to fail, reducing the lifespan of your work. So, before you grab your trowel, you need to do the following:

  • Remove any loose plaster, wallpaper, or hardware.
  • Fill dings and cracks with wall filler. For larger cracks, apply filler in layers, allowing each layer to dry in between applications.

Remove dust and dirt; wipe down walls with a damp cloth and allow to dry. To make sure your wall is 100% ready for tiling, we would recommend to paint it with PVA

Step 2: Levelling

Next, you’ll need to smooth out the surface. If you don’t have a professional level handy, a long piece of flat lumber will do the trick. Slide the lumber over the surface, checking for bumps or rough patches. Anything less than 3 mm is okay, but larger imperfections must be smoothed down with sandpaper or a sander. Although this can be time consuming, skipping this step could cause your adhesive to fail.

Tip: For precision leveling, use a laser level

Step 3: Plan Your Project

Now comes the fun part: piecing your project together. After measuring out your surface area, count how many tiles you’ll need to do the job. Add another 10% to your order to ensure you have enough materials in case some break. It’s also good to store a few more in your closest – especially for tiles that are patterned – for repairs down the road. Like any consumer product, tastes change over time, and it could be difficult to find the same tiles when you need them for replacements.

Now, unbox the tiles and start arranging them on the countertop or floor as they will appear on the wall. Then, with a marker, put a line where the middle tile will go. Move the tiles aside and ready the trowel.

FYI: Can I put tile directly on the wall? Ensure that the area you are working with is even and without dust or dirt, as well as being dry. Prior to attaching the tiles, if the surface is properly prepared it will be easy to apply the adhesive and set the new tiles in place.

Step 4: Choose Your Adhesive

Choosing the correct adhesive is essential to a successful tiling job. Generally, adhesives come in two varieties:

When deciding what option to choose, consider the job you’re doing and on what surface. For example, when tiling smaller tiles (less than 30 x 30 cm) to plasterboard, ready-mix adhesives work well. For bigger tiles, or any size of porcelain, a powdered adhesive is necessary. The powdered option is also the only choice when doing floors. And for any project that will get wet, be sure the adhesive is waterproof.

Step 5: Paste down, tile away

With the adhesive selected and the wall prepped, now it’s time to dig out your trowel and lay down the paste. Smooth out the adhesive with the straight edge of the trowel first, and then use the notched edge to score the wet stuff in the direction that the tiles will be placed.

Next, apply the first tile at the bottom of the wall in the position you marked earlier. Once you have it lined up properly, push down on each corner to set it, and then apply a tile spacer to create the gap between the adjacent tile. Once you’ve completed the bottom row, move on to the second. After all your tiles are set, wipe off any excess adhesive with a damp sponge.
