Proseal PS Primer
PROSEAL-PS-PRIMER
Proseal PS Primer is a single-component, solvent-borne surface conditioning and adhesion-promoting primer specifically developed for movement and control joints formed in porous construction substrates. The material penetrates into the open pore structure of the substrate and forms a continuous interfacial bonding layer which enhances chemical compatibility and mechanical anchorage between the joint surface and subsequently applied elastomeric sealants.

Overview
Key Features
- Improves interfacial bond strength of joint sealants applied on highly absorbent and weakly bonded mineral substrates such as concrete, cementitious masonry, gypsum boards, timber and natural stone.
- Consolidates friable and dust-prone joint faces and reduces substrate absorbency.
- Provides surface stabilization and sealing in aggressive service environments including areas exposed to traffic, saline moisture, fuel contamination and oil spillage.
