Kreidezeit Shellac Insulating Primer

Product information "Kreidezeit Shellac Insulating Primer"

The Kreidezeit Shellac Insulating Primer is a primer that cures and is used to block through-staining caused by water, rust, soot or nicotine on all absorbent wall and ceiling surfaces, such as plaster, wallpaper, wood and wood-based materials. 
Shellac is a natural resin obtained from the secretion of female scale insects, which secrete it onto twigs to protect their offspring. This secretion is then harvested twice a year from the shrubs – which are primarily found in East India and Thailand – yielding different grades of quality. This so-called ‘stock lacquer’ contains 60–80 per cent pure shellac. This results in numerous applications in the pharmaceutical industry (coating for coated tablets), in insulating paints, wood polishes, fabric finishes, chewing gum, inks and much more. 
Kreidezeit Shellac Insulating Primer can be painted over with Kreidezeit wall paints if required; however, it is unsuitable for use with lime-based plasters and should not be used on damp substrates or where moisture is penetrating.

Full list of ingredients 
Fermentation alcohol (denatured with MEK, IPA, Bitrex), wax-free shellac, linseed oil varnish, titanium white, talc, quartz, silicic acid

Application
Remove any dirt from the substrate as far as possible (brush off, wash off). Stir the product thoroughly before use and apply a thin, even coat to the dry surface using a brush or roller. One coat is usually sufficient to seal minor stains; for heavy stains, apply 2–3 coats, allowing the surface to dry between coats and without sanding in between.
Can be overpainted with Kreidezeit wall paints after approx. 24 hours. For subsequent coats of white wall paint, the isolating primer can be applied selectively. For subsequent coats of coloured wall paint, or coats to be finished with wall glazes, the isolating primer must be applied over the entire surface; otherwise, coloured marks may appear. If glossy patches have formed due to the primer being applied too thickly, the dried shellac isolating primer must be sanded to a matt finish before painting over with wall paints. The product may be thinned with Kreidezeit alcohol up to 10 % vol.

Drying time
Dust-dry after approx. 30 minutes. Dry and ready for further work after approx. 12 hours at 20 °C.

Cleaning of tools
Clean immediately after use with alcohol, then wash with Marseille soap, Corfu soap or olive care soap and water.
