Content:
1, material requirements
1, SBS asphalt waterproof rubber elasticity
Water-soluble, odorless, viscous black liquid, solid content of greater than 50% of its main technical performance indicators should be consistent with the provisions of product standards, and should the factory certification.
2, the main tool
Cheung Ping-large brush, small brush with short Bing, scythes scraper, a small scraper, a small trowel, small drum, the size of broom, scissors, rolling brush and so on.
Second, the operating conditions
1, grass-roots should be checked, and go through the transfer of inspection procedures. Primary surface should be smooth, do not have sand, cracks, loosening phenomenon, highlighting parts of the transition should be smooth.
2, primary and roof protruding parts (such as the parapet, wall, piping, etc.) are connected, he shall be made for the 100 to 150 mm radius of the arc-shaped.
3, the construction temperature above 5 ℃. Rain or rain with four more yet to dry or windy weather, not construction. Grass-roots level should be the basic drying, water content not more than 15%.
4, get ready machinery equipment, vertical transportation derrick erection of good material, installed hoist system equipment.
Third, the construction operation process
1, process
Clean-up grassroots → → rubber brush the first pass is dry, paint brush a second time, while laying the first layer of glass cloth → hard work, the brush rubber → third time is dry, brush over the fourth rubber, laying the same time The second layer of glass cloth → hard work, the brush all over the compound → Fifth is dry, brush the sixth time → closed water test compound.
2, cleaning up the grassroots
The primary surface protrusions, mortar and other foreign body cleanse pimple may not have
