Why installers are making the switch
Every feature is an installer benefit — not a chemistry spec
- Superior toolability
Tools cleanly with a wet finger or standard tool. Stays workable longer than polyurethane.
Paintable Without Bleed-Through
Accepts latex paint without staining or bleed-through. No masking tricks required.
Soap & water cleanup
Clean hands and tools with water. No solvents. No smell. No wasted time.
UV & Weather Resistant to last a lifetime
Maintains adhesion and elasticity after years of sun and weather exposure. No chalking or cracking.
No primer needed
Direct adhesion to most substrates. Skip the primer step on most applications.
- The proof
"But water-based can't perform like polyurethane…"
That's the most common thing we hear — and the most common thing installers take back after their first job with AU-1. The performance is in the chemistry, not the carrier. AU-1 maintains permanent flexibility, strong adhesion, and full UV resistance. The difference is you clean up with water instead of solvent.
