To receive the quality waterproofing, an isolated surface clear of dust, a dirt and a dust, level and dry.
The Painting waterproofing from bitumen mastics put a brush on dried up and ogruntovannye surfaces, using receptions of painting works. A surface pomazyvajut mastic in two-three receptions by layers by thickness 2мм, without leaving not painted over places. Each layer put only after the previous will cool down and its quality will be checked up. The waterproofing layer should be continuous, without bowls, cracks, swellings and backlogs. These defects appear, if mastic is put on crude or crude surfaces. Defective places clear away, dry and cover with mastic anew.
At great volume of works (more than 300... 500м 2 ) a waterproofing from bitumen mastics put on surfaces of walls of cellars and other designs in the mechanised way. Mastic submit to a work place in avtogudronatore and put by means of a fishing tackle with an atomizer attached to the pump avtogudronatora by a flexible metal hose in diameter 25мм. At isolation drawing work process in such a way is considerably accelerated, quality of a waterproofing and practically improves, bitumen losses are excluded.
At the device of horizontal isolation from a solution or asphalt on the bases or walls of cellars isolated surfaces preliminary level a solution, filling, all vertical seams. Then at cement or asphalt isolation put a layer of a coupler from a corresponding material and continue a laying in usual sequence, stacking the stone first rows on preliminary spread layer kladochnogo a solution.
At packing on the bases of horizontal isolation from roofing felt or roofing material (fig. 105 see, izoljatsionnyj a material in advance clear from protective posypki that insulation layers stuck together is better. Panels cut on preparations of the necessary length and curtail into rolls. On the prepared surface of a laying levelled by a solution spread the first insulation layer. On it put a layer razogretoj mastics in the thickness 1... 2мм and from above at once paste the second layer. A surface of rolled isolation cover from above with a layer of hot mastic in the thickness 2мм and continue a laying.
At the device of a waterproofing from rolled materials use following tools. Steel knifes (fig. 108, cut a roll and brushes (fig. 108,) clear roofing material and roofing felt from mica or sandy posypki, a brush (fig. 108,) or grebkom (fig. 108,) put and level mastic, steel grebkami level asphalt mastic (fig. 108, ). In konusnom a tank (fig. 108, ) with a cover transfer razogretuju mastic from bitumovarki to a work place, a ladle spill mastic.
Shpatelem with the extended handle smooth edges of the panels pasted on a vertical or inclined surface (fig. 108, .
Shpatelem with the short handle put, level and smooth mastic at zadelke seams and joints okleechnoj waterproofings (fig. 108, .
a Fig. 108. Tools and the stock, waterproofings applied at the device :
And - a knife for are sharp a rolled material, - brushes for clearing of rolls, in, g - a brush and grebok for namazyvanija and mastic levelings, d - steel grebok, e - a tank for mastic carrying over, - a ladle for mastic flood, z - shpatel with the long handle, and - the same, with the short handle
At isolation of vertical and inclined surfaces at first prepare a rolled material, cutting its panels of the necessary length. Start to paste from below upwards. Bitumen mastic at first put on an isolated surface, and then on a rolled material. In the beginning unroll a roll and paste one of the panel ends, fixing the necessary direction of a carpet. After that a roll skatyvajut, put on an isolated surface a layer of mastic and gradually unroll a roll, putting mastic a layer 1,5... 2мм, and, pressing a panel to a surface, a rolled material paste on the basis. A panel paste so that they incorporated to each subsequent panel in longitudinal and cross-section joints vnahlestku on 100мм.
Are not supposed an arrangement of one seam over another in adjacent insulation layers and a label of rolled materials in mutually perpendicular direction. The pasted panels grind in to the basis and earlier pasted layers wooden shpateljami with the extended handle, on horizontal surfaces pasted materials, besides, prikatyvajut a skating rink in weight 70... 80кг with a soft facing.
Seams nahlestki in addition coat with the mastic which has been wrung out at grinding and ukatke of a material. An external surface of the top layer izoljatsionnogo a material cover with a continuous layer of mastic in the thickness 2мм.
