OVERVIEW

Cementitious stucco, mortars and plasters bond tenaciously to StuccoPrime while preserving the integrity of the underlying waterproofing membrane. Applied wet-on-wet, StuccoPrime and the stucco scratch coat cure together, forming a strong chemical and mechanical bond.

 

StuccoPrime dries slowly to allow time for the stucco scratch coat to be applied to the primer, and cures in contact with the stucco scratch coat. StuccoPrime is not water-reduced and will not emulsify when exposed to water. This single-component, 100%-solid, silyl-terminated polymer (STP) is designed for brush, roller or trowel application.

 

PROSOCO R-Guard® StuccoPrime is a special-order product available to approved applicators only. Site-specific training by an R-Guard field technical representative is required to project-certify stucco installation crews in proper use and application of R-Guard StuccoPrime.
