Primary surface dry (moisture content of ≤ 9%), a solid, flat, smooth, smoothness meet regulatory requirements.
Straight angle grassroots yin and yang (negative angle of minimum radius of 50mm, sun angle minimum radius of 20 mm) made of rounded;
A variety of embedded parts have been installed and fixed completed.
Primary inspection and acceptance → brushing primary treatment agent → yin and yang corner parts of the sticky Shop additional layer of waterproofing membrane → positioning elastic line → paving waterproofing membrane → coil received the first treatment → inspection and acceptance
The base surface to clean up after the grass-roots level inspection and acceptance.
Primary treatment agent, even brushing the surface of the grass-roots again. Brushing primary treatment agent, according to a direction, uniform thickness, no leak at the end, not flowing. Wait for the primary treatment agent drying.
Pop-up the Stones roll control line on the base membrane at baseline, with a paper knife isolated paper gently cut open, be careful not to scratch the membrane tear release paper from the the membrane adhesive surface slowly, and membrane slowly rolled forward along the baseline Shop. Immediately after the paste with a scraper forced to move to catch up to the outside pressure, exhaust air, the coil firmly pasted at the grassroots level, adjacent to the overlap between the two rows of coils. Membrane of the long and short side lap width of 80mm. Pay special attention to landing edges rolled tightly bonded. Omo membrane and an additional layer between full bonding.
Waterproof layer construction to complete the self-qualified, according to the program mortem report. The Construction Notes: DAS waterproof Stones roll, at the coil shut should be temporarily sealed (available tape or thick cement mortar seal), closing up the wall at the head of water to prevent excessive loss. The short edge connector adjacent rows membrane should be staggered over 300mm width, in order to avoid multi-layer joints overlapping web paste the uneven service. Waterproof layer construction is completed as soon as possible organizational acceptance, hidden in a timely manner, not suitable for prolonged exposure. Supplemented by appropriate fixed when membrane in facade construction and medium format larger when, at the corner of the site. Membrane in the construction site by the contamination, use a clean damp cloth to clean the membrane.
