for mineral surfaces


A colorless, transparent, light-resistant and non-aging primer for pre-priming and consolidating absorbing and sandy mineral surfaces like plaster or concrete. Important: the mineral surfaces should be clean, dry, intact and without any mould release agent! Forms an elastic, satin-gloss film after drying. The product should be diluted with 4 parts of water. In the case of difficult surfaces please use the concentrate.

Thinner: water




  • Shake well and stir – if necessary – before use.

    • The mineral surfaces should be clean, dry, intact and without any mould-release agents.
    • The kind of use depends on the absorbance of the surface being treated.
    • Size / primer is mixable with water, but dries up to a water-insoluble film.
    • Normally one uses the product in dilution with 4 parts water. In the case of difficult surfaces (very absorbent / sandy) please use the concentrate. (It is important that there is no closed film on the surface!)
    • The product can be applied with a brush, a paint roller or an airbrush.
    • Please clean tools like brushes as soon as possible with water or water and soap.
    • Please don´t use the product below temperatures under 5 °C object- and room-temperatures. Also beware the application on warm surfaces or under direct sun irritation!
    • As primer afterwards we recommend i.e. Schmincke primer 1, strongly absorbent 50512 or Schmincke primer 2, 50514.
    • Please take care that for outdoor paints additional arrangements have to be made (e.g. paints with maximum light fastness; sealing with acrylic lacquer, glossy 50586 or acrylic lacquer, satin glossy 50587).
    • Close immediately after use.
    • Store in a cool and dry place.
    • Protect from frost.
    • Individual pre-tests are required.
