VOC BLOCKER
Our VOC blocker is a specialized sealer used in interior painting to lock in:
-
odors, smoke, pet and chemical residues
-
stains
-
harmful volatile organic compounds (VOCs) from existing surfaces.
-
Old paint and primers
-
Cabinets and composite wood
-
Flooring, adhesives, and glues
-
Water- or mold-damaged materials
It functions by sealing the surface, preventing VOCs from off-gassing into the indoor air.
This not only creates a healthier environment for your home or office, but also ensures better adhesion and a longer-lasting paint finish.
