- Foam brush
- Grout sealer
- Any other recommended supplies and cleaning items listed on the grout paint directions
Fix the tiles and grout where possible. There might be areas with broken tiles or disintegrating grout. Clean up and replace what you can.
Clean the tile surface using a tile cleaner to inhibit the growth of mould and mildew. Follow the directions closely, including allowing time to let the spray rest on the surface.
Tape your tile. If you will clean up paint as you go, you can skip this step. If not, use painters tape to cover the tile, allowing only the grout to show through.
Begin painting. White is fine, but coloured grout paint in a darker tone might be a better option. It will hide stains better and provide a welcome contrast. Use a foam brush as wide as the grout.
Work in small sections at a time with small amounts of paint. Use long strokes to apply the grout paint. Paint one coat over the whole surface and clean as you go. Let dry completely, according to the manufacturer's recommendations. Then complete a second coat, and a third if needed.
Follow the instructions on the grout paint regarding cleanup and tool cleanup.
Seal the grout. This will help maintain the surface colour and protect from dirt and stains.
