MasterProtect FL 749 is an acrylic copolymer-based chunk padding that is totally prepared for priming and replenishing extremely permeable masonry prior to painting MasterProtect high-build acrylic wall coating products
MasterProtect FL 749 works well in interior and exterior, vertical surfaces, above grade, and substrates where absorbency is not uniform.
Use a heavy-bodied solution like MasterProtect FL 749 to close pores and offer great surface closure. The breathable MasterProtect FL 749 allows moisture vapour from the substrate to escape. Moisture-resistant; will not disintegrate when subjected to wet-dry cycles. The workability of MasterProtect FL 749 is good for simplicity of use and decreased labour expenses. On damp surfaces, MasterProtect FL 749 can be used. It's easy to operate and doesn't require the use of air. VOC compliance is required by the EPA and most regional governments.
