POLYARMOR
PolyArmor Primer
High-Adhesion Primer System
Better bond. Better surface control. Better finish. Fewer surprises from the existing roof.
Why use the primer?
Better bond. Better surface control. Better finish. Fewer surprises from the existing roof.
On modified bitumen, it helps fill texture, granules, and voids so the final membrane lays cleaner.
Substrate Compatibility & Field Verification
PolyArmor Primer is a high-adhesion primer designed to lock into properly prepared roof substrates and create a stronger, cleaner bonding surface for the PolyArmor membrane system.

Fills surface texture and improves membrane finish
The Bonding Step That Makes the Finished Membrane Look and Perform Better
Aggressive Adhesion
Promotes strong bond to nearly all properly prepared substrates, except silicone or silicone contamination.
Adhesion Test Required
Always perform a field adhesion test before full installation. Jobsite verification beats assumptions.
Fills Voids on Mod Bit
Helps fill granule texture, micro-voids, and surface irregularities on modified bitumen.
Improves Final Finish
Creates a smoother, more uniform surface so PolyArmor finishes cleaner and more professional.
Reduces Surface Defects
Helps minimize air release, texture telegraphing, roughness, and uneven appearance from porous substrates.
System Confidence
Adds a controlled bonding layer between old roof conditions and the new PolyArmor membrane.
Substrate Compatibility & Field Verification
Broad Adhesion
Metal, aged single-ply, asphaltic surfaces, concrete, wood, and properly prepared roof surfaces.
Silicone Exception
Silicone and silicone-contaminated surfaces are not approved unless specifically tested and accepted in writing.
Always Test
Perform and document an adhesion test. Field verification overrides assumptions.

Raw Materials, Managed at Scale
PolyArmor Primer draws on the same managed raw material supply chain behind every PolyArmor system, supporting consistent formulation from batch to batch.
