Can You Put Peel and Stick Tile Over Existing Peel and Stick Tile?

If your floor tiles have gone out of style, it might be the right time to upgrade the looks with unique, durable, and contemporary alternatives. Current flooring trends will embellish your floor, bathrooms, kitchen, and the water-prone backlash. With the hottest wood and stone looks in the market, you need to gather the right tools and get the ball rolling.

Fortunately, you don’t have to start from scratch. If you prepare the underlying surface well, it’s possible to install tile over tile. The following tips will help you to install new tiles without the hassle of breaking up the old ones:

How to Put Peel And Stick Tile Over Existing Peel And Stick Tile

1. Assess The Old Tile

Start by conducting a thorough inspection of the underlying layer to highlight any surface irregularities. Pinpoint all the foundational problems that might come back to haunt you down the road. Remember to take note of any discoloration that might indicate trapped moisture that could damage your grout.

The moisture problem will worsen once you cover the tiles, so it’s vital to address it first. Find out whether the dampness is a result of too high humidity or water seeping from underneath. Either way, you’ll have to install a damp proof membrane to prevent mold issues in the future.

2. Prepare The Surface For Installation

Installing new tile over an uneven surface will not produce the results that you desire. The cracked tiles need to be chiseled out before you fill-up the spaces. Look out for flaws in the grout, especially around the skirting.

It’s best to remove the skirting if you want the best finish possible.

If the initial tiles didn’t bond well with the mortar, they could develop cracks over time. Buttered tiles come with a groove that allows them to blend with the mortar and create a sturdy joint. Once the defective tiles and skirting are out of the way, you can identify the cracks and greasy spots that need your attention.

3. Clean The Base Layer

Sweep the base layer to get rid of dust. A vacuum cleaner can also help to remove the fine dust particles. After mopping the floor with water, you will notice the grease that’s quite difficult to remove.
Put a spoonful of baking soda and about 1 cup of vinegar in a bottle and shake vigorously. Spray it on the greasy spots and wait for five minutes as the solution cuts through the grime. Use a sponge and clean water to rinse and wipe the surface.

4. Lay The Groundwork

For the best results, you need to use waterproof mortar. Waterproof mortar works well for stone, vinyl, ceramic, and porcelain tiles. It’s especially beneficial to moisture-prone areas such as kitchens and bathrooms.
You need to start from the center and work your way to the walls.

Mark the centerline with chalk and use a string to guide you. Get the right spacers to allow 2-3 mm grout between tiles. With tile spacers, you don’t have to agonize over the accuracy or width of your lines.

Prepare for installation and acquire the following items:

  • Trowel
  • Epoxy mortar
  • Powder mastic adhesive
  • Drum roller

5. Install The Tiles

Scoop the mortar with a trowel and apply a thin layer, 300mm wide. If you apply too much mortar, it will start to dry before you install the tile. Draw lines with the edge of your trowel to expose the grout.
Apply the dustless powder mastic adhesive to the back of your tile and press it firmly on the mortar. The combination of mortar and adhesive will create a bond that will last for decades without needing repair. Avoid silicone adhesives in wet areas where splashing is a concern.

Follow this process:

  • Drop a string line down the middle
  • Arrange tiles along the string
  • Install the spacer
  • Install the tiles along the string

6. Secure The Tiles

Even if you have completed laying your tiles, you’re not out of the woods yet. It’s vital to apply more adhesive on the grout to give it an extra layer of protection. This initiative prevents moisture from seeping into the seams between your tiles.

Seal the tile work in the following ways:

  • Use premixed grout from the hardware
  • Apply the waterproof grout with a trowel
  • Run a roller over the tiles to secure them firmly
  • Clean the tiles with ammonia

By taking the right steps to secure the tiles, they can withstand foot traffic and last longer.
