Preparation is the most important step before any tile installation. The main objective is to create the most smooth and uniform surface possible so the tile can be evenly placed. Doing so will ensure your beautiful hard work and perfectly aligned backsplash, shower, or other tile installation will last for years-and-years to come.

Here’s a few tips for prep, depending on the existing material you have where you’re laying the tile.

New Drywall

New drywall is easiest because you already have a smooth, flat surface to work on. All you have to do is seal the walls with a primer and once dry, go over the wall with medium-grit sandpaper to create a slightly rough surface. Vacuum up the excess dust then go over the wall with a damp cloth or sponge to remove any remaining dust. But make sure the wall is completely dry before you start applying glue.

Painted or Textured Drywall

Begin by removing paint from the existing surface. If you see any holes or cracks in the wall, patch it up with spackling compound and sand the entire patched surface with medium-grit sandpaper. Use a vacuum to remove any remaining dust. It’s also worth going over the walls with a wall cleaner to remove any oils or grease that remain on the surface.

Plaster

If the plaster is relatively new, you can proceed by patching up any cracks or holes with spackling compound and sand the surface until smooth.

However, if you are weary about the condition of the wall, consult a professional to see if the plastered wall will support a fresh tile installation. If the plaster wall is good to go, we recommend applying an acrylic primer before adding any wall adhesives.

Wallpaper

Always remove any existing wallpaper and glue before tiling. In doing so please make sure the surface is free of dust, moisture, and grease prior to applying the adhesive as it may affect the ability of the mortar to adhere to the wall.

Tile

For a previously tiled wall, there are two options. Option one is to chisel off the pre-existing tile. Alternatively, you can tile directly over the old tile, however, this does not guarantee a clean finish. If you do decide to go with the second method, make sure that you treat the old tile with a grinder to create a proper surface for the adhesive.
