Veradur stain & alkali block
Fully Opaque - Alkali Resisting - Water Based - Stain Blocking Acrylic Primer
VERADUR STAIN & ALKALI BLOCK is a high coverage, white, water based,
stain blocking primer formulated with acrylic resins, specially designed for
sealing out and suppressing most bleeding type stains including crayon, graffiti, water sensitive stains, dried water stains, grease, ink, pencil stains, asphalt, creosote, rust, coffee stains, nicotine stains, smoke stains and related odours as well as yellowness or other dirt. It is a non spattering, fast drying primer for interior and exterior use that combines excellent hiding power and strong adhesion even over chalky surfaces. It is applied easily, smoothly, evenly and develops a strong, stable and flat-mat surface that ensures exceptional leveling and better adhesion to all finishing emulsion or acrylic coatings. The use of VERADUR STAIN & ALKALI BLOCK provides the safest method of priming stained surfaces, porous surfaces as well as surfaces coated with lime or poor quality coatings, whilst allowing the surface to breathe normally ensuring high water vapour permeability and a total breathable coating system. With special,
technologically improved acrylic resins in its synthesis, VERADUR STAIN & ALKALI BLOCK resists strongly against the alkalinity of most interior and exterior masonry surfaces such as fresh concrete (poured, precast or block constructions), new plaster, drywall and walls leveled with cement based leveling compounds or ready mixed, water based, liquid putties.
Due to itsexcellent hiding power and its superior whiteness, it is highly recommended as
an intermediate primer when an extreme colour change from dark to light shades is desired, reducing the coatings required for the topcoat. It is an ammonia free coating with minimal odour.
