GROUT SEALER & GROUT PAINT. RESTORE OR CHANGE THE COLOUR OF WALL & FLOOR GROUTING Grout Magic from Smartseal is similar, but far superior to a grout paint. It's the perfect solution to restoring wall and floor grout to make it look like new. Grout Magic is also a grout sealer that's used to restore the original colour and look of old grouting. If required, use Grout Magic to totally change the colour of wall or floor grout. Before using Grout Magic it's important to use the Grout Cleaner to thoroughly clean the grout. For best results we strongly recommend using the Grout Magic Pre-Treatment to ensure the grout joints are clean. If cement or grout residue is found on the tiles use the Grout Haze Remover prior to using the grout paint.
