All of the ingredients in the clay paint are natural. The filler is clay, the binder is clay, methylcellulose or kaolin. Mica (which gives an appealing sparkly touch), quartz sand and flax tow are examples of possible additives. The clay pigment contains no preservatives, solvents or biocides. The clay paint filters the air, is very breathable, and is not suitable for wet rooms or outdoor use. The room temperature must be at least +6 C.
- Goal: Clay paint is meant above all for coating clay plaster-rendered surfaces. It can also be applied on mineral plasters, gypsum board, gypsum fibre board (better to spackle the base for the paint when applying it to gypsum board).
- Tone: The tone of the clay paint depends on the type of clay used (usually red, grey, blue, yellow, white), which can be tinted using natural pigments. Depending on the company, there are about 8 primary colours and over 160 blended tones.
- Paint expenditure: 1000 ml will coat 5-12 sq. m, depending on surface.
- Price of a square metre is determined based on layers of paint (2-4), choice and quantity of pigments. Spinels are the most expensive pigments (1 kg is about 100 euros), while ochers and umbers are cheaper (1kg ~ 25 euros).
