Description
Kerakoll Primeplus Surface Primer is a highly advanced styrene butadiene polymer designed to prime, stabilise and seal substrates prior to the application of Kerakoll tile adhesives and smoothing and levelling compounds. Kerakoll Primeplus Surface Primer increases the adhesion and prolongs the working time of Kerakoll adhesives and Kerakoll smoothing and levelling compounds, and can be used on absorbent surfaces both internally and externally.
Instructions:
Preparation of substrates:
Preparation of all substrates is crucial to the success and longevity of the installation. All substrates, must be rigid, flat, clean, dry and sound and be free of any contaminants. Anything that could compromise adhesion to the substrate, such as dust, dirt, oil, grease, laitance, sealers, waxes and curing agents will need to be mechanically removed. Ensure that all substrates and backgrounds are strong enough to carry the weight of the final coverings and fixing materials, and that any maximum weight limits are not exceeded.
The temperature of the substrate must be above 5°C when Kerakoll Primeplus Surface Primer is applied. Underfloor heating systems must be switched off at least 24 hours prior to application. Ensure that where necessary, a damp proof membrane has been incorporated in the subfloor.
Application:
Shake well before use. Apply a thin, even coat to the surface using a paint roller, brush or sponge. Take care not to over apply the product, as this can extend the drying time and cause the primer to skin over. Allow Kerakoll Primeplus Surface Primer to become touch dry before applying tile adhesive or self levelling compound. Kerakoll Primeplus Surface Primer will take approximately 15– 20 minutes to dry, avoid heavy trafficking once Kerakoll Primeplus Surface Primer has dried.
