Expert Verdict — Reviewed by the SuperArbor Pro Desk
TopGard 4000 is the standard reflective top coat in JM's liquid-applied restoration line; over asphalt, always stage it with the buff base coat so bleed cannot migrate into the white film. Verify substrate adhesion and priming requirements before the full field application. Choose tan where reflectivity is still desired but white glare is a concern.
Review the manufacturer's safety data sheet for ventilation, skin protection and slip hazards when applying liquid roof coatings.
Order JM TopGard 4000 white reflective roof coating for your restoration project.
