Hydro Sealant is a waterproofing system with concrete, cementitious and masonry substrates.
It penetrates the surface through moisture absorption and reacts with the free lime forming a hard crystalline material which blocks the pores against water pe*******on and becomes an integral part of the structure.
It provides positive and negative waterproofing against dampness and ground water as well as hydrostatic pressure.

Prior to application, pre saturate the surface to be treated with clean water and ensure any free standing water is removed before commencing with coating
Apply Hydro Sealant in one or two coats, each at right angles to the other.
Dual coat application is applicable only on water containing units, damp walls or on flat concrete roofs / surfaces. For adequate waterproofing protection and results a minimum
coverage of 1 ,5kg per m2 should be specified. ie:- 1 st Coat, 1 kg per m2 and 2nd Coat 1/2 kg per m2. Moisturize surface before next coat is applied.
