How do you tile over existing tiles?

You might wonder if you can tile over tiles on a tiled surface.

So can you tile over existing tiles? Yes, in many cases. As long as the tiles are still in good condition. Here are the steps.

EVALUATE THE EXISTING TILE

Begin by inspecting the tiles.

You may see mildew, discoloration or stains in the grout lines. This is a sign that moisture has seeped in. This moisture problem can lead to rotting and weakening of the wall or floor.

Next, check that the tiles have been properly installed. The new layer won’t work if the old tiles aren’t perfectly flattened or lined up. If there is any warping, it’s worth repairing. Use a four-foot ruler to locate any high spots or voids on the surface.

Next, lightly tap the tiles with a wooden mallet (or a small piece of a 2-by-4). The tile is likely loose if you hear a hollow sound when tapping the tiles. These should be noted.

Even if some absorption or tiles are not properly placed, you can still fix the problem and put new tiles on top. (Learn more in the next section. If too many tiles are damaged, you might want to remove them and start over.

If the tile’s surface is uneven, the tiles need to be removed.

Also, consider the thickness and weight of the tiles. The weight of tiles can make them heavy. This is especially true for tiled floors. It may not matter if the area is small, such as a bathroom or entryway.

Adding more tiles to your flooring can increase the thickness of your tiles. This could increase the height from 3/8″ up to 1/2″. This could impact the ease of opening or closing doors. It can also cause a height difference between the floor below and the next, which could lead to a trip hazard.

These are all reasons why it is a good idea to speak with a professional before you decide to tile over tiles.

PREPARATE THE SURFACE

The most common tiling error is failing to prepare the surface. Even if the surface is already tiled, it is important to prepare the surface for successful trusted tiling contractors in Auckland.

Reread the markings you made while assessing the tiles. To fill in any voids, use thin-set or floor-levelling compounds to grind down any high points. Remove any loose tiles and apply new adhesive to fix them in place.

To make the adhesive bond better, you will need to roughen any tiles that are already in place. Use 80-grit sandpaper to sand the entire area. Next, vacuum up the area, scrub the tiles well, and rinse them off.

It’s now time to move on to the next layer.

INSTALL THE NEW TILES

Layout your tiles, and then cut them to size. To ensure a consistent spacing between tiles once they are in place, you can also add tile spacers.

Spread your adhesive on the old tiles using a toothed trowel. Cover a small section of tile that is less than a foot wide. Do not cover too much of your surface at once. You may need to wait for the adhesive to dry before you can set the tiles.

You could also apply the adhesive directly on the back of your new tiles. This method will not hold the tiles as well and should only be used if the old tiles are in excellent condition.

No matter how you apply adhesive, the trowel’s toothed edge should be used to “comb” it. You should have straight grooves, without any bends or swirls.

Place each tile one at a while, pressing down on them until they are all in place. Wipe off any adhesive residue with a damp sponge. Continue doing this until you have tiled the entire area. (Do not lippage.

After the adhesive has set, which takes about 20-30 minutes in most cases, remove the tile spacers. After 24 hours, grout between tiles the gaps

That’s all! Enjoy your stylish new tiles.
