Many people assume that to replace tiles and install new ones, they must first remove the existing tiles from the walls or floors. However, thanks to modern techniques and technology, it is now possible to install new tiles over old ones using a special adhesive.
Installing ceramic tiles with adhesive on mosaic minimizes the hassle of removing old tiles. In this guide, we will cover the necessary tools and step-by-step instructions for this process.
Tools Required for Installing Ceramic Tiles on Mosaic
Ceramic tile adhesive is a strong product that allows porcelain floor and wall tiles to be securely attached to existing tiles or mosaic surfaces. However, to ensure the best results, specific tools are required. These include:
- New ceramic or porcelain tiles in the desired design and quantity
- Special adhesive for tiles
- Wooden mallet
- Electric or manual sandpaper
- Trowel for plastering
- Tile spacers
- Grout
- Tile separators
- A few old tiles to repair broken mosaic sections and create a uniform surface
Steps to Install Ceramic Tiles with Adhesive on Mosaic
Once you have gathered the necessary tools, you can start installing the new tiles using adhesive. The steps are as follows:
Step 1: Planning the Layout
First, visualize the final layout of your project in your mind or draw it on paper to ensure you have a clear plan. This step helps prevent changes or adjustments later.
Keep in mind that installing new tiles over old ones will add approximately 1.5 cm to the height and width of the surface. This might affect elements such as door frames, electrical switches, and outlets, which may require modifications.
Step 2: Surface Preparation
The surface must be smooth and problem-free before installation. If any mosaic tiles are cracked or loose, they should be repaired or replaced with old but intact tiles to create a stable base.
Step 3: Cleaning the Surface
Ensure the surface is completely clean and free from grease, oil, dust, or any contaminants. Wash and thoroughly clean the old mosaic tiles to ensure the new adhesive bonds properly.
Step 4: Sanding the Surface
Use an electric sander or coarse sandpaper to roughen the surface of the existing tiles. This step is crucial because smooth surfaces may not provide adequate adhesion for the new tiles.
After sanding, wash the tiles again to remove any dust particles. You can also apply a primer to further enhance adhesion. Before applying the adhesive, make sure the surface is structurally solid.
Step 5: Applying the Adhesive and Installing Tiles
Prepare the tile adhesive according to the instructions on its packaging. Spread a thin layer of adhesive on a small section of the existing tiles and on the back of the new tile (combined method).
Immediately place the new tile on the adhesive and press firmly. If necessary, gently tap it with a wooden mallet to ensure proper adhesion.
Step 6: Grouting and Finishing
Allow at least 24 hours for the adhesive to dry completely before proceeding with grouting. Fill the gaps between the tiles with grout to secure them in place.
Immediately clean the surface after applying the grout to avoid stains or an untidy appearance. Once the grout hardens, your tiling project is complete.
