METACRYLICS / Roof primers · adhesion, rust, asphalt bleed, and porous surfaces
Start with the existing roof—not a generic primer. Compare the current Metacrylics primers, then open the substrate guide and technical documents that control preparation, adhesion testing, coverage, and coating compatibility.
FIELD COATINGS · 1976—NOWMetacrylics primers support different jobs: Bleed Blocker controls asphalt oil migration, Black Primer protects prepared metal, TPO Primer is for qualified weathered TPO, Roof & Tile Primer penetrates porous surfaces, and Epoxy Primer supports demanding adhesion conditions. The written system and field testing determine which one belongs on the project.

Single-component rust inhibitor primer.
Single-component acrylic primer that stops asphalt oil bleed-through and discoloration.
Two-part epoxy primer for demanding adhesion.
Penetrating primer for tile and porous surfaces.
Primer formulated for adhesion to weathered TPO membranes.
Open the roof guide for the actual substrate. It connects inspection and preparation to the approved primer, detail treatment, reinforcement, acrylic or silicone weathering layer, and current documents.
Use these answers to get oriented, then confirm the current TDS, SDS, written system, and project conditions.
Bleed Blocker Primer is a single-component acrylic primer used in approved asphalt-roof systems to control oil migration that can discolor the finished coating. Confirm preparation, compatibility, coverage, and the complete coating sequence in the current documents.
No. Asphalt, weathered TPO, prepared metal, tile, masonry, and difficult non-porous surfaces present different adhesion and compatibility requirements. Follow the substrate-specific guide and written specification.
No. Metacrylics positions TPO Primer for qualified weathered TPO. Acrylic Clear Base is the current recommended primer path for PVC, subject to inspection, preparation, and adhesion testing.
Open the selected primer product page and its current TDS, then confirm the roof-system specification. Surface condition, porosity, texture, and test results can change actual use.
