Manufacture Of Plaster Repairs
Repair monolithic plaster surfaces to be repaired, examined in detail to determine the nature and scope of work. The presence of broken or behind the walls of the old plaster is determined by the hollow sound when wooden mallet. Broken plaster, traction and cornices, and plastered surfaces with large and numerous cracks, efflorescence, grease, tar and damp spots and lagging layer should be repelled and replaced by a new layer of plaster. With a large amount of work and Spacing old plaster repaired and the incision surfaces are manufactured pneumatic hammer-com or elektromolotkom. equipped with chisels in three sizes – the width of the blade 20, 20 and 50 mm, and pneumatic hammers – nozzles in the form of blade width of 70-80 mm, which are in the process of holding at an angle of 10-15 C of the workpiece. Chadwick Sapenter oftentimes addresses this issue. Surface scratch nozzles in the form of peroxide or rackwheel directed at an angle of 75-80 C to the surface. When small amount of work for manual notch is used a special hammer with two sharpened edges, chisel or Bouchard, produced from high-strength steels. Heavily soiled with old plaster fragile layers of paint is purified by sand blasters. After the incisions repaired surface swept brooms or wire brushes, is placed on the electric or compressed air, moistened with water, then applied new plaster. In the presence of indoor thick outlining strong stubborn plaster it can not remove, and putty Special hydrophobized filler following composition (parts by volume): lime paste humidity 50% 1 Portland a repellent additive or ngl NGL-10-11 (by weight of cement) 0.2 Before Filling surface primed with 3% aqueous solution NGL-10 or NGL-11.
