Hydrobloc SD 730 is a water-based penetrating surface treatment formulated with lithium / Sodium silicate and fluorosilicate technologies. It penetrates into concrete, cementitious screeds, plaster and masonry substrates, where it reacts with free calcium hydroxide to form additional calcium silicate hydrate (C-S-H). This reaction increases surface density, hardness and durability. HYDROBLOC SD 730 is designed for weak and dusty concrete surfaces, roof screed strengthening, substrate preparation before waterproofing systems, fair-faced concrete conditioning and reduction of dusting and water absorption. It is not a film-forming coating and becomes an integral part of the substrate without significantly changing the surface appearance.

Key Features & Benefits:

HYDROBLOC SD 730 provides deep penetrating densification, improves surface hardness, reduces dusting and chalking, lowers water absorption, improves abrasion resistance and enhances substrate cohesion. It also improves adhesion of subsequent coatings, reduces permeability, remains breathable, is VOC-free, easy to apply and suitable for interior and exterior use.
