Kreidezeit Casein Primer is a transparent primer for many internal applications before subsequent coats are applied.
Casein Primer has a firming effect and lowers absorbency. It is an important and low-cost component of every paint and plaster job. Use on absorbent plasters, plaster boards and old mineral based coatings.
Since it contains the same binder, it is the ideal primer for Casein Marble Paint. Subsequent layers will have a strong chemical bond.
Apply on all untreated surfaces such as clay plaster, lime plaster, cement plaster, gypsum plaster, stone and concrete.
Not suitable for smooth, non-absorbent surfaces and permanently humid surfaces.
- Powder – mix with water.
- 250 g will cover 40-60 m²
For mixing the primer, it is best to use a 10 litre bucket and an agitator (drill + whisk).
Add the Casein Primer (250 g) to 3 litres of clean cold water while stirring constantly to ensure all lumps are removed.
After an expanding time of approx. 30 minutes, stir again thoroughly and dilute with 5 litres of water.
Apply Casein Primer evenly and saturated. Only apply as much primer as is absorbed by the substrate.
Remove excess material (wet glossy spots) with a cloth before drying.
Application temperature min. 8°C.
The Primer must be applied on the same day as mixing. Do not use Primer that smells bad or rotten under any circumstances as there is a danger of prolonged odour problems even after drying!
Dried after approx. 8 hours at 20°C and safe to coat with paints or plasters based on lime or casein.
