D-16 Hydrostop

Siloxane-based clear impregnation liquid for grout joints. It protects the grouting product (for 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 caused by moisture penetration and frost. It maintains its water repellency for 2 years outdoors and 5 years indoors.
