What is DOWSIL 795?

A one-part, neutral-curing, medium-modulus silicone building sealant made by Dow. The chemistry is silicone and it cures with moisture from the air, which is why Dow keeps it out of totally confined joints. It carries ASTM C920 Type S Grade NS Class 50 Use NT G A O, with 50% movement.

How do you apply DOWSIL 795?

For structural applications, Dow requires prior review and approval by its local sales application engineer. Clean and dry the joint, install backing material, setting blocks, shims and tapes, and mask the edges. Dow generally requires no primer on non-porous surfaces, but recommends a test placement and may require primer on porous surfaces. Do not apply to wet or frost-laden surfaces or where the surface temperature exceeds 50 °C.

Can you paint over DOWSIL 795?

Dow does not recommend DOWSIL 795 where the sealant will be painted. TremFlex 834 is a paintable acrylic latex for general caulking, with its movement rating on its own page. It is not a substitute for a structural-glazing bond. For a painted nonstructural joint, confirm the substrates and movement requirement before choosing it.

Is DOWSIL 795 waterproof?

It weather seals a facade joint against rain, and Dow's own limitations rule it out on surfaces that are continuously immersed in water. For a joint that sits underwater, call the counter before you order.
