PROPERTIES
SimpleBAU Quarz-Haftgrundierung CONTACT PRIMER is a ready-to-use agent and ensures high adhesion on demanding substrates, i.e. surfaces with low absorbency, very smooth surfaces with paint and adhesive residues that are difficult to remove.
SimpleBAU CONTACT PRIMER reduces and balances the absorbency of the substrate, forming a strongly adhesive layer. Due to the optimal selection of the aggregate grain size and the ratio of aggregate and resin, the product can be processed excellently on the substrate, forming an even and rough surface.
The product is vapour permeable and, once the performance properties have been achieved, resistant to frost and the effects of water. SimpleBAU CONTACT PRIMER has thixotropic properties – it does not flow off vertical surfaces.
SCOPE OF APPLICATION
SimpleBAU CONTACT PRIMER is especially recommended as a primer for smooth surfaces and substrates with low absorbency (existing ceramic floors, dense concrete, old floors with epoxy resin covering).
SimpleBAU CONTACT PRIMER is suitable for all surfaces made of concrete, terrazzo, OSB boards in interior and exterior areas of buildings.
It is ideal for surfaces with adhesive and paint residues that are difficult to remove.
SimpleBAU CONTACT PRIMER is suitable:
- for mineral, acrylic, silicone, silicate and mosaic plaster,
- for indoor and outdoor use,
- as primer when using levelling, repair and self-levelling screeds, concrete screeds, adhesives, plaster,
- for vertical and horizontal surfaces,
- for underfloor heating.
PREPARATION OF THE SUBSTRATE
The substrate should be firm, even, load-bearing, dry, bonded, free of cracks and salt efflorescence, clean and free of adhesion-reducing substances (dust, dirt, oils, grease, wax, adhesive and paint residues). Cement and gypsum substrates must be bonded and dry.
PROCESSING
Immediately before use, mix the entire contents of the pack accurately by hand or with the aid of a low-speed mixer until a homogeneous consistency is achieved. Do not dilute with water and do not mix with other substances.
SimpleBAU CONTACT PRIMER Apply evenly over the entire surface with a tassel or roller. Allow to dry for at least 6 hours.
Do not glue down coverings or apply plaster until the primer has dried completely.
The priming process should be carried out at an ambient and substrate temperature of +5° to +25° C. Wash off any soiling immediately with plenty of water. Remove dried-out soiling with solvent.
When working outdoors, the primed surface should be protected from direct sunlight, rain and frost until the performance properties are achieved.
