Clean Wall® PREPAIR – Base/Primer

PREPAIR is a pigmented dispersion primer for walls and ceilings surfaces indoors and outdoors. It is odourless and is produced without addition of plasticisers, preservatives, or solvents, and is free of fogging-active substances.  PREPAIR is suitable for ceilings and walls on woodchip, fleece and embossed wallpapers, plaster, concrete, polystyrene, plasterboard, etc. indoors, especially for sensitive areas such as doctor’s practices, offices, nursery schools, shops, hospitals, food trade, schools, residential areas, etc.

Suitable substrates PREPAIR – Base/Primer

Surfaces Suitable surface types are masonry, fair-faced masonry, plaster, concrete, glass-fibre fabric, woodchip, fleece, embossed wallpapers, dispersion, mineral and silicate paints. The surface must be clean, dry and viable. Observe the guidelines of VOB (Construction Tendering and Contract Regulations), part C, DIN 18 363, sec. 2 and 3. 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.

Tinting 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.
