If a tile floor is in good condition but is a colour that does not go with the rest of your decor, it is possible to change its colour. Paints containing a urethane resin can be used to safely and permanently change the colour of floor tiles. For the best results the tiles must be clean and in good condition with no cracks. While the grout lines can also be painted, it is recommended to paint those in a contrasting colour, if painting is necessary, to keep the look of the floors authentic.
Sweep the floors to remove any dust or debris that could become caught in the paint. Wash the tiles well to remove any spills or topical stains, and allow them to dry.
Carefully paint the surface of each tile. Brush the paint on in one direction only, starting at the back of each tile and pulling the brush toward you. Work carefully at the edges of tiles to avoid getting the paint on the grout joints. Allow the paint to dry completely overnight.
Apply a top coat of urethane sealer to protect the new colour. Paint the urethane on in the same way the paint was applied; in one direction only, from front to back. Allow the sealer to dry overnight before walking on the floors.
