HomeShield Dampstop Duo is a specially formulated premium quality acrylic primer with superior alkali, damp and efflorescence resistance properties both from positive and negative sides of the wall. It consists of penetrative polymer in combination with pore blocker which blocks the surface porosities of plastered wall/putty and hardens the surface to effectively counter the dampness both from the positive and negative side. Dampstop Duo also prevents alkali leaching/ efflorescence and enhances the durability of the topcoat paint system.

An excellent waterproofing/damp proofing barrier system, it blocks the porosities of the substrate through partial penetration coupled with controlled film formation on the substrate surface. Dampstop advanced nano additives in the emulsion act as pore blocker and impart hydrophobicity to the substrate, making the substrate watertight.
