PRIMER – Water Based Acrylic Primer
A high performance, water based acrylic primer designed to improve adhesion between substrates and decorative coatings, including microcement, concrete, cement, plaster and lime based surfaces.
Its deep penetrating formula strengthens surface bonding, regulates absorption and helps prevent cracking caused by premature moisture loss.
