1. If as plaster you have decided to use clay, pay special attention to its knitting properties and to as far as it is plastic. The fact is that than it is more at it this property, subjects there is high probability of the fact that when drying solution it will crack. To check clay for plasticity, knead its small amount, gradually adding water until the lump ceases to stick to hands.
2. You stick together ball with a diameter of 2 cm. Put it on plain surface and flatten, pressing palm. If cracks, clay of maloplastichn were at the edges formed. Smooth edges, in turn, are the certificate that the rich clay, i.e. has good plasticity. It is also possible to check clay, having rolled small lump in zhgutik one and a half-two millimeter thick and about 25 cm long. Bend plait arch. Than more it can be bent without formation at the same time of cracks, especially soft clay.
3. Degree of plasticity is regulated by addition to sand clay. Content it in solution is 50 – 80%. In order to avoid clinking add polypropylene fiber to solution, it is also possible to use wool, hay or straw. Clay before mixing with these components should be wetted previously.
4. You apply clay and sand solution on surface by means of the palette and metal grater. After putting plaster the surface can be not leveled as roughnesses will improve the fortress of contact with finishing layer.
5. Pay attention that the clay mortar long enough dries. On drying of layer one centimeter thick about two days leave in the open air. Therefore, that the plastered room has dried out, not less than one and a half weeks will be required. To prevent flaking of the applied plaster, use plaster grid or shingle.
