Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use 289 as the prep coat over flashed seams, splits, and repaired areas before a white acrylic reflective coating, since a non-bleeding patch base is essential for a clean finished roof. Work it into the surface by brush or trowel and let it skin before coating. Restrict use to smooth, clean, sound substrates as directed for lasting adhesion.
Roof patching work involves ladder and rooftop hazards, so follow fall-protection practices and the product safety data sheet during application.
Order Henry 289 Acrylic Roofing Sealant in a 3.5-gallon pail to prepare your roof for a reflective acrylic coating.
