To successfully tile over painted tiles, you must first remove all of the existing paint.
Preparing Painted Tiles for Tiling
It's essential to thoroughly prepare painted tiles before attempting to tile over them. This process is crucial for proper adhesion and a long-lasting tile installation. Here's how:
Paint Removal Methods
According to the provided reference, there are a couple of ways to get rid of the paint:
- Scraping: Use a utility knife to carefully scrape off the paint from the tile surface. This method is more effective for loosely adhering paint.
- Solvents: Apply a solvent, such as mineral thinner or white vinegar, to dissolve the paint. Make sure to follow the manufacturer's instructions and take necessary precautions. Ensure that the tiles are fully clean and dry before moving to the next step.
Why Remove the Paint?
- Poor Adhesion: Paint provides a smooth, non-porous surface that new tile adhesives will struggle to bond with, leading to potential tile failure down the road.
- Unpredictable Results: Applying a new layer of tile directly over a painted layer can lead to unpredictable results, including cracks and loose tiles.
- Proper Installation: Removing the paint ensures that your new tiles adhere properly to a sound, level surface.
Important Note Regarding Priming
- Avoid PVA: The reference states clearly that PVA should not be used to prime a surface before tiling.
Step-by-Step Guide for Tiling Over Painted Tiles
Here is a summarized step-by-step guide:
- Remove All Paint: Utilize a utility knife or solvent, as outlined previously, to completely remove all paint from the existing tiles.
- Clean the Surface: Thoroughly clean the tile surface to remove any residue from paint removal.
- Assess the Tile Surface: Make sure that the surface is even and suitable for tiling. Address any irregularities if needed before proceeding.
- Apply Proper Adhesive: Select the correct adhesive for the tiles you are using, and follow the manufacturer's directions carefully.
- Install New Tiles: Carefully set the new tiles onto the adhesive, ensuring proper alignment and spacing.
- Grout the Tiles: Allow the adhesive to dry fully according to product instructions before grouting.
- Clean Up: Finally, clean any remaining residue from the tiling process.
By following these crucial steps and removing the existing paint, you will have a secure and lasting tiled surface.
