TREMproof WB Primer

TREMproof WB Primer

Single Component, Water-Based, Low VOC Primer

TREMproof WB Primer is a single-component, waterbourne primer designed to act as an adhesion promoting primer and to minimize absorption of the waterbased membranes into porous surfaces and prevent “green cracking” and other inconsistencies in the waterproof membrane.


TREMproof WB Primer is used on all concrete, masonry, fibre cement board and any other porous substrates prior to application of Tremco waterbased membrane applications.
