Finishing the building facade plaster "bark" includes four stages:

Preparation of the work surface isOne of the most important stages. To start the facade surface is carefully leveled cement-sand plaster. Plastering should be carried out according to a pre-set profiles majachnym set using the level. Their installation should be made at a distance of not less than 100-150 mm.
Between beacons throw a cement-sandplaster, which further tightening the rule. If the screed remain defects, they are treated poluterom or float. After about 3-4 hours the prepared surface will be overwritten in a circular motion.
After one day, if necessary, canspend one more grout. In that case, if the grout throws in the warmer months, it is advisable to water it daily with water to avoid cracking.
If necessary, this type of plaster can beused for facades, insulated Penoplex or foam. In this case, the surface of insulation required to pretreat the solution of the adhesive, which is placed on top of the reinforcing mesh.

At the "bark" use to more accuratelyand accurate application it is recommended to use a metal spatula. Perhaps the most difficult part of the work lies in the fact that there was observed the necessary thickness of the layer corresponding to the grain size. Plastering itself does not differ from the fillings, except that the solution should be stretched over the surface until the tread is not a small furrow.
To get a spiral texture on freshplaster light movement is carried out with a plastic float. It should make a reservation that, if the material is not dried up, the result is not too happy, but as soon as the plaster dries, it significantly transformed.
The surface is polished againplastic float, but more powerful movements. During operation, it must be ensured that the plaster does not stick to the grater. At the end carefully rubbed clean all the joints.
