Clay plaster

Primer RED

Liquid primer with coarse grain size before the application of coarse clay plaster mortars. RED provides grip and plaster adhesion on smooth and/or poorly absorbent substrates such as high-insulation bricks, KS elements, concrete, lime and gypsum plasters, old dispersion coatings (solid but porous), old synthetic resin plasters and others.

Deep penetrating primer and stabiliser: Water, potassium water glass, dispersion, additives < 1%. Primers: Limestone powder, water, water glass, clay, dispersion < 5% (improvement of adhesion properties and application safety), perlite, cellulose fibres, methyl cellulose, xanthan. Granulation RED 0 – 1.8 mm, YELLOW 0 – 1 mm, WHITE is without granulation.

Supply forms, coverage
10 l bucket, 24 buckets/pallet, liquid, for approx. 30 m2 . Item No. 13.430 5 l bucket, 56 buckets/pallet, liquid, for approx. 15 m2 .

Storage in closed containers is possible dry and cool (frost-free!) for at least one year. Tightly close opened containers again.

As a rule, agitate undiluted thoroughly. Water addition of up to 25% is possible when strengthening clay plaster surfaces on deep penetrating primer and stabiliser. For primers always up to 5%.

The substrate must be stable, firm and clean. Substrate temperature 5 – 25 °C. Remove old, poorly adhering coatings, wash off watersoluble coatings. Brush off sandy plasters and wash. Prepare heavily sanding substrates with CLAYTEC deep penetrating primer and stabiliser. Fresh plaster, lime or cement plasters must be at least 10 days old and dry. Pronounced alkaline substrates such as fresh concrete surfaces with sintered skin must be professionally fluorinated (neutralised) and formwork oil residues washed off. CLAYTEC primers have no strengthening or blocking effect.

Application is done with a short pile roller (RED with a foam roller) or with a brush.

A subsequent application is only possible after complete drying, at the earliest after 48 hours. Drying depends on temperature and humidity.
