To select the right material, you should carefully study all information about each type, consult the seller or with other specialists. On readiness to use putty there are several types:

1. Dry mixes. They contain all the components necessary for the performance of puttying operations: fillers, additives, binders. To work with such putty it must be diluted with water in the proportions indicated on the package. The advantage of dry mixes is that they do not shrink, and therefore can be used for the finest work. The disadvantage is that they require strict adherence to the prescribed proportions of water and mixture, as well as thorough mixing. The period of use of the diluted putty usually does not exceed a day.
2. Ready mixes. They can be immediately applied to the wall, as they are ready for use. The disadvantage is that after drying a slight shrinkage occurs, and therefore it is better not to use ready-made mixtures for finishing and do not apply a thick layer.

To coat the inner corners, the mixture is applied on both sides of the corner, and then pressed into the sickle (special adhesive glass) pre-pasted into the corner. It is very important to evenly distribute the putty between the walls. For plastering of external corners it is required a metal corner which it is necessary to cut off on height. Putty is applied to the sides of the outer corners, and then the corner is pressed into it. After that the corner is closed with an additional layer of putty.

You can also apply a large amount of putty on the corner, and then after completely drying, treat this place with a wooden shoe wrapped with sandpaper.
