D-16 Hydrostop

Waterproofing agent for grout joints

Siloxane-based clear impregnation liquid for grout joints. It protects the grouting material (whether its grouting tiles, granite, glass bricks, etc.) and its surface from moisture and stain absorption, thus maintaining its durability and color. It seals grout hairline cracks related to temperature variations or rapid dehydration during grouting. Use it indoors (e.g., bathroom, kitchen) to ‘prevent’ the absorption of moisture and subsequent mold creation. Use it outdoors to ‘avoid’ tile detachments that are likely to be caused due to moisture penetration and frost. It maintains its water repellency for 2 years outdoors and 5 years indoors.



1lt/25-50m² per coat, depending on the dimension of the tiles and the width of the joint
