How To Use Craft Foam As Ceramic Tile!

Step 4 When Dry, Grout

Mix grout as recommended by the manufacturer.  I like to make it just a little "runny" to give better control and ease in getting the grout into the open spaces.  Go around the entire can, smoothing the grout with the applicator. When it has sat for 30 minutes or so, go over the surface with a damp sponge, removing as much grout as possible from the tiles/images.  Be careful to not remove grout from the grout lines.
