Primeplus
Priming and bonding agent.
Suitable for tile adhesives, smoothing and levelling compounds, for internal and external use.
Key Features:
- Wall and floor primer for absorbent surfaces
- Quick drying
- Ready mixed and ready to use
- Consolidates substrates prior to installation
Areas of Application
Primeplus 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. Primeplus 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 for Use
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 Primeplus 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 Primeplus to become touch dry before applying tile adhesive or self levelling compound. Primeplus will take approximately 15 – 20 minutes to dry, avoid heavy trafficking once Primeplus has dried.
Cleaning
Clean tools with warm water after use.
