Method number 1. Grout
If the gap reaches only a few millimeters (no more than 5), then for its location you can use grout. You can purchase a white grout or use the one that the inter -seams were processed. The advantage of this method is the stability of the grout to the penetration of moisture and the preservation of color for a long period of time. To strengthen this grout effect, it is possible by processing it with a means of protection against dirt and rust (fugue-shusk). Grout is applied with a rubber spatula.
