Sikagard-535
Sikagard-535 is a low-VOC, single-component liquid-applied acrylic vapor-permeable air and water barrier for above-grade wall assemblies on plywood, gypsum sheathing, concrete, and CMU. This 5 gallon pail (part 465458) places at approximately 80 sf/gal for 40 mils dry, passes ASTM E 2178 and E 2357, and is evaluated by the Air Barrier Association of America. It cures to a tough monolithic membrane with approximately 6 perms vapor permeance, UV stability for 12 months of exposure, and Class A flame/smoke ratings.

Frequently Asked Questions
What coverage does Sikagard-535 need for 40 mils dry?
Apply at approximately 80 sf/gal to achieve a uniform 40 mil dry film thickness.
What air-barrier tests does Sikagard-535 pass?
It passes ASTM E 2178 air permeance and ASTM E 2357 assembly air leakage, and is evaluated by ABAA.
What vapor permeance does cured Sikagard-535 keep?
Approximately 6 perms (ASTM E-96B), so wall assemblies can dry while resisting air and water.
What substrates take Sikagard-535?
Above-grade plywood, gypsum sheathing, precast and cast-in-place concrete, and concrete masonry units.
What UV exposure window does Sikagard-535 allow?
UV stable for 12 months of exposure. Longer rainscreen exposure needs Technical Services guidance.
What size is the Sikagard-535 pail on this page?
This page is the 5 gallon pail, part 465458. The PDS also covers 55 gallon drums.
