Safe coating for sealing the inside of drinking water concrete tanks and cisterns. Easy to use; just add water (plus Damtite Bonding Additive for previously-painted or non-porous surfaces) and mix. Eliminates dampness; resists mold/mildew & flaking/chalking while beautifying and sealing all pores & voids.

It withstands over 22 psi of hydrostatic pressure (equal to holding back a 48 foot high wall of water). Plus, it is breathable, so moisture does not get trapped behind the surface. It also reduces Radon Gas infiltration. Not formulated to withstand foot traffic. Tip: Wear protective gloves and goggles.
