How to paint tiles

Start by giving your tiles a thorough clean to remove any dirt, grease, or soap residue. Use a heavy-duty cleaner or mix sugar soap with water for best results. Scrub the tiles well with a cloth or sponge, then rinse thoroughly with clean water to remove any leftover cleaner. Allow the tiles to dry completely before moving on to the next step, as any moisture can affect the adhesion of the tile primer and paint.

Once the tiles are clean and dry, lightly sand the surface using fine-grit sandpaper, such as a 400 grit. Sanding dulls the glossy finish of the tiles, which helps the tile paint adhere better. Be sure to go over the entire surface evenly. After sanding, wipe away any dust with a damp cloth and allow the surface to dry completely.

Remove any silicone from the tiled surface, as paint will not adhere properly to silicone. Carefully scrape it off with a suitable tool and clean the area thoroughly before proceeding. 

Use painter’s tape to cover any areas you don’t want to paint, such as fixtures, grout lines, or edges around the tiles. Be precise with your taping to ensure clean, straight edges. Cover the surrounding floor or benchtops with drop sheets to protect them from paint drips or spills. 

To ensure the paint adheres properly and lasts, apply a primer that is suitable for tiles - it creates a strong bond between the tiles and the paint. Use a small paintbrush to get into the corners and edges, then switch to a paint roller for the larger areas. Follow the manufacturer’s instructions and let the primer dry completely before moving on to the next step. 

Once the primer has dried, apply the first coat of tile paint. Choose a paint that is specifically designed for tiles, such as a water-based enamel paint. Use a small paintbrush to paint along the edges and in any textured areas, and use a foam paint roller for smooth, flat surfaces. Start painting from the top of the tile area and work your way down to avoid drips. Let the first coat dry completely, which usually takes a minimum of eight hours. 

After the first coat has dried, apply a second coat for a smooth, even finish. Depending on the colour and coverage, you may need a third coat. Allow each coat to dry thoroughly before applying the next one, following the drying times recommended by the paint manufacturer. 

For added durability, especially in wet areas, apply a clear water-based sealer. Use a clean brush or foam roller to apply the sealer evenly across the painted surface. The sealer helps protect the paint from wear and tear, extending the life of your freshly painted tiles. Once applied, allow the area to cure for at least 48 to 72 hours before using it.
