Suitable substrates PREPAIR – Base/Primer
Surfaces Suitable surface types are masonry, fair-faced masonry, plaster, concrete, glass-fibre fabric, woodchip, fleece, and embossed wallpapers, dispersion, mineral and silicate paints.

Remove non-adhesive old paints completely. Treat algae and mould chemically and remove residues. Remove dust, loose parts of plaster, old, non-sticking coatings and sinter layers. Clean intact old paint layers. Wait 4 weeks before coating new, highly alkaline plasters. Insulate expected penetrations on the basis of nicotine or other substances beforehand. Prime chalky old paints and highly absorbent mineral surfaces (e.g. plasters, gypsum blocks) with the DEEP primer.
Tiniting with PREPAIR – Base/Primer
Up to max. 5% with commercial tinting and full-tone colours. Check the compatibility in every case. Apply mixed product immediately. Always make a test coat before use. Complaints at a later stage cannot be accepted. Notice: Tinting can change the defined characteristics. When adding more tinting colours or mixing pastes, the product might thicken and shrinkage cracks might appear in the dried paint film. When mixing yourself, mix the required total amount to avoid differences in shades of colour. Health and environmental properties change when adding tinting products.
