Spray Foam Roof Coating Project Planning

The coating over a spray polyurethane foam roof protects the foam and must be maintained as part of the roof system. Recoating decisions should be based on the foam condition, existing coating, repairs, moisture, drainage, and current system requirements.

Inspect the foam and protective coating

Document exposed or damaged foam, cracks, blisters, mechanical damage, penetrations, previous repairs, coating erosion, drainage, and signs of moisture. Damaged or wet foam should be removed and repaired by an appropriate method before recoating.

Confirm compatibility and current instructions

Review the current Lexis product data and safety data for every proposed cleaner, primer, sealant, reinforcement material, and coating. Confirm that the products are compatible with the existing roof and with one another. Complete any required adhesion testing on the actual roof before ordering the full project quantity.

Define the work before ordering

Document preparation, repairs, detail treatment, application method, coverage or film-thickness requirements from approved product data, weather limitations, safety responsibilities, and exclusions. Contractors should include these items in the written scope. Building owners doing their own research should use the same checklist when comparing options.

Ask Lexis about product selection

Send the roof type, approximate area, current condition, existing coatings or repairs, photographs, and project location through the Lexis contact page. These details help narrow product choices without assuming that one system fits every roof.
