Single-Ply Roofs
Designed for weathered single-ply roofs after the membrane is positively identified. TPO and PVC do not use the same primer path.
The published silicone assembly shown is for TPO. Send PVC projects to the technical team for project-specific confirmation before material selection.
Read preparation and application guidance ↓What to bring to the review
Roof area, location, existing membrane or coating, photos of the field and details, leak locations, and known moisture or drainage concerns help the team review the project.

Coating Solutions for TPO or PVC
TPO and PVC are single-ply membranes with different preparation requirements. Use TPO Primer only on qualified, weathered TPO. Acrylic Clear Base is the recommended primer path for PVC membranes. Confirm the exact membrane before choosing a coating path.

Preparation guidance for your installer
Common roof concerns
- Open heat-welded seams or aged repairs
- Chalking, contamination, or incompatible prior coatings
- Movement around curbs, drains, and terminations
Field preparation
- Identify TPO versus PVC before selecting primer
- Deep-clean until rinse water runs clear
- Use TPO Primer only on qualified TPO; use Acrylic Clear Base for PVC and verify adhesion
Release checkpoints
- All seams pass a probe test
- The primer matches the identified membrane
- Representative adhesion tests are accepted

Answers before the roof brief.
Use these answers for planning, then follow the current written specification for the project.
Can an existing TPO / PVC roof be coated?+
A TPO / PVC roof may qualify when the assembly is identified, sound, dry, repairable, properly prepared, and proven compatible through project-specific testing. Wet or unsound areas must be addressed before coating.
What preparation does Coating Solutions for TPO or PVC require?+
Identify TPO versus PVC before selecting primer. Deep-clean until rinse water runs clear. Use TPO Primer only on qualified TPO; use Acrylic Clear Base for PVC and verify adhesion. Confirm the selected acrylic or silicone specification before application; preparation varies with the existing surface and field conditions.
How is the material quantity calculated?+
The estimator uses measured roof area, detail length, system family, planning term, and a waste or texture allowance. Actual ordering must follow current coverage rates, specified film build, surface profile, and field verification.
Which technical documents belong in the project file?+
Start with the system specification, then include the current product data, safety data, applicable detail drawings, approvals, warranty requirements, and any written project-specific instructions.
When should the technical team review the roof?+
Request a review whenever the substrate is uncertain, moisture or drainage is a concern, adhesion results vary, prior coatings are present, warranty coverage is planned, or field conditions differ from the published system.
