Ready types of plaster mixes are convenient in application. Besides are added to them by production various chemical additives improving their plasticity, coupling with the processed surface. But sometimes there are no ready plaster mixes near at hand, and walls are required to be processed urgently. In that case recipes of ready plaster mixes which it is possible to make with own hands will be useful.
It is required to you
- Lime, sand, water, cement, clay, fiber, capacity for mixing.
Instruction
1. The main component of limy types of plaster is, respectively, lime. Such plaster mixes grapple with surface long and dry rather long time. Therefore it is not necessary to hurry, working with them. Limy plasters are ideal for drawing on former plaster, serve as additional paroizolyatsionny layer, create good ecological climate indoors. Thickness limy plasters impose no more than one-two centimeters on surface.
2. Composition of limy hard putty for rendering base – the first plaster coat which fills cracks on the processed surface, has to be the following. 25 kg of cement, limes of 14 kg, sand of 23 kg and water 42 liters are required. It is necessary to do mix for rendering base smetanoobrazny. Reduce proportions if plasters it is required to you much less.
3. To make plaster mix for priming coat (it has to be in the form of the test), 25 kg of cement, 21 kg of lime, 27 kg of sand and 52-53 liters of water are required. The last nakryvny smoothing plaster coat requires mix from 25 kg of cement, 28 kg of lime, 40 kg of sand and 77 liters of water.
4. Cement for internal works is preferable to batch of plaster mixes M150, 200 brands. For front works it is necessary to take M300 brand cement. For difficult surfaces where on the building perhaps strong influence of weather patterns, the environment, it is necessary to take cement for plaster of M400 and 500 brands.
5. There is also other type of self-made plaster – clay. Such plaster is resistant to mold, fungus, teplopronitsayema. Is additional sound-proof layer. It is easy to wash away self-made clay plaster at uselessness from wall. And the washed-away structure can be not utilized, and to part with water and again to use for designated purpose in other place.
6. To make clay plaster independently, good quality clay, greasy, flexible which in the form of the rolled ball from clay and water does not stick in hands and does not crack is required. Clay is diluted with sand in proportion 50:50. Then it is necessary to add to structure for its strengthening and plasticity small fiber. It can be cut from straw, wool, polypropylene, hay. You can use the crushed plastic bag as fiber. Further to mix water to the necessary density of plaster is added. Clay plaster quickly stiffens therefore it is necessary to work with it dynamically.
