Description

The Sika Sikasil WS-290 is a one-part, neutral-curing silicone sealant. It features an ultra-low modulus, non-staining formula with excellent adhesion.

This sealant cures to a durable, flexible building sealant that performs well under dynamic conditions. It accommodates long-term movement of +100–50% in properly designed joints and is particularly suitable for Exterior Insulation Finish Systems (EIFS).
