GRAMOS® BARRIER GEL is a permanent adhesive varnish to protect the walls and other parts of the spray booth from paint overspray and dust. It is a water solution for the protection of walls (stainless, painted, etc.). Not suitable for galvanized surfaces. The coating will not dry at normal temperatures and its surface traps dust and paint overspray. Removal is done with a spatula followed by washing with water. It is suitable for spray booths where there is no continuous spraying and where there is more dust and overspray contamination, it is especially suitable for heavier conditions and is very similar in properties to GRAMOS® TACKY SURFACE COATING. The application means must be washed with water only.
