3M 7000028421 Booth Coating 1 Gallon Overspray Protection

Product Description

The 3M 7000028421 is a water-based liquid booth coating formulated to protect paint booth walls, light fixtures, and other interior surfaces from paint and primer overspray. Applied with a conventional paint gun, it dries to a clear film that shields surfaces without altering light transmission or surface function. When removal is needed, plain water is all that is required — no solvents or harsh chemicals. At 9.1 pounds per gallon unit, it is straightforward to handle and stage inside a working booth environment. This product is used by auto body technicians, fleet refinishers, and industrial paint crews as part of routine booth maintenance.

This coating is suited for both production and small-shop paint booth environments where overspray buildup on walls, ceilings, and light covers is a recurring maintenance issue. It is applied as a liquid coat using standard spray equipment already present in most refinishing operations, making integration into existing prep workflows simple. A single gallon covers standard booth surfaces per the technician's typical application thickness.
