Plaster works.
Preparation of surfaces

That the plaster solution was more strongly linked to surfaces, them prepare, creating an artificial roughness. Besides, them clear of every possible pollution. Long service life of plaster in many respects depends on preparation.

Stone, brick, concrete surfaces than 10 mm are necessary to clear, choose well seams on depth not less. If surfaces smooth them is better to notch an axe, a chisel or other tool. It is possible to apply electric manual cars. As much as possible strokes on a surface carry out so that to leave a notch: not less than 1000 pieces on 1 m 2 .

Wooden surfaces demand stuffing drani or strengthenings by a metal grid. Wide boards can be jarred on from the become wet plaster and to tear it, therefore they should be split and in nadkoly to hammer small klinyshki. Wooden surfaces can be closed pergaminom, a bast mat, a sacking or felt. They warm partitions or walls and reduce zvukoprovodnost. In rublenyh walls preliminary seams cover with a solution: when the solution will dry up, hang the specified materials and fill dran.

If rublenye walls were prokonopacheny they can be plastered not earlier than in a year. (It is necessary for full deposits.) in all cases it is recommended to cover grooves preliminary with a solution zapodlitso with a surface of walls and it is good to dry. Walls can be veiled felt or a bast mat.

From contact of warm air with cold, getting through walls, on their internal surfaces the condensed moisture is formed. From it wood quickly rots, air indoors becomes damp. To avoid it, it is possible to arrange so-called paroizoljatsiju, i.e. To close premise walls pergaminom or roofing material on all their height with overlapping of edges a minimum on 50 mm. On it there should not be fragmentary places that leads to infringement paroizoljatsii. Dran it is possible to fill on a tree or on paroizoljatsii.

Before stuffing piece drani it sort on prostylish and target. Prostylish dran narrower, curve, thickness not less than 3 mm. Target dran has width of 12-15 mm, a thickness of 3-5 mm. On target drani plaster keeps, therefore more strict demands are made to it.

Preparation of wooden surfaces: and - an arrangement dranits, - stuffing drani, in - position of a nail in a hand: 1 - prostylish dran, 2 - target dran At first fill prostylish dran, having it at an angle 45 ° to a floor, distance between lathing of 20 mm. It slightly beat on the ends so that dranitsy have not fallen. Having filled on a wall the first row prostylish drani, on it fill target dran which have perpendicularly prostylish, i.e. On the other hand under the same corner. Dranitsy of 25-30 mm one from another have on distance. Beat them, since the bottom part. Nails hammer through one-two prostylish dranitsy (fig. 54). The nails keeping prostylish dranitsy, on a stuffing course take out and apply in business. The ends dranits necessarily beat. At stykovanii between them there should be a distance of 2-3 mm. To impose the ends dranits against each other it is impossible.

Nails for work hold in a pocket. Hammer in nails so. At first a nail put to dranitse, not strong blow of a hammer hammer on 5-7 mm. Then take away a hand from a nail and strike to it the second blow by a hammer with such force that the nail has been completely hammered. Having filled the first row drani, start the second etc. On ceilings dran fill the same as and on walls.

If dran fill on felt between prostylish dranitsami leave distance of 15-20 mm, between days off - 20-25 mm. Sometimes felt close from above pergaminom or roofing material then from a roofing material face sheet it is necessary to remove completely posypku that the solution has more densely stuck to roofing material.

If weak, it it is more convenient to hang felt together, and it is even better to reel up it on a round stick, gradually to unroll on a surface and to fix the nails hammered on half of length. Other half of nail bend. If it not to bend, and completely to hammer, felt can break.

(For example, the wooden partition adjoins to brick, stone or concrete) it is necessary to tighten Joints of diverse surfaces at first a grid strip, having blocked a place of a joint on 50 mm in that and other party. Then fill dran on a partition and start to oshtukaturivaniju. Thus on a joint place never there is a crack.
