Coating Solutions for Spray Polyurethane Foam

SPF roofs break down from UV weathering and need recoating to survive. Metacrylics coatings provide excellent resistance to weathering and ponding conditions, extending the life of the foam beneath.

Acrylic or silicone?

Choose an option to see its layers in order. Our team checks the roof, primer, coating thickness, and product amount before the project starts.

Spray Polyurethane Foam project questions

Answers before the roof brief.

Use these answers for planning, then follow the current written specification for the project.

Can an existing Spray Polyurethane Foam roof be coated?

A Spray Polyurethane Foam 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 Spray Polyurethane Foam require?

Preparation depends on the exact substrate and condition. Inspection, moisture review, cleaning, drying, repairs, detail work, and representative adhesion testing come before the final primer and coating sequence.

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.
