Usage: all kinds of industrial and civil buildings, structures waterproof, impermeable, various underground waterproof and non-leakage parts of waterproofing. Construction process: 1. Roof construction grassroots basic requirements: A: grassroots required 1:2.5 cement mortar sweeping movements into 20-30mm thick leveling layer should be sweeping movements flat pressure light, solid, firm, smooth, can not afford the sand, not a punch , loose, drum kits, pockmarked face and other phenomena exist. Its flatness application 2m long straightedge checking, leveling layer and the gap between the ruler must not exceed 5mm. B: the surface must be dry screed, cement mortar should have sufficient strength, and its moisture content does not exceed 9%. C: leveling layer with prominent roof structure (parapets, chimneys, etc.) and the junction should be made of the corner radius of 20mm arc-shaped, slightly fell into the water around the mouth of the pit should be made for drainage. D: Pan screed slope and should meet the design requirements and other relevant provisions. (2) Process: cleaning grassroots additional adhesive layer processing primary surface membrane surface bonding adhesive membrane closing the exhaust end coil compaction and edge treatment as a protective layer 3. Operation process: A: Cleaning grassroots: pre-construction acceptance Qing Yin grassroots re-clean. B: Additional layers: Yang angle, tube roots, fell into the water, and other special parts of the additional layers need to be done. Can be used with polyurethane coating or layer of membrane. C: Primary and coil surface coating: The spread on a clean sheet on the grass, with a long brush dipped (401 or 404) adhesives, coating evenly on the sheet, and then coated on the base construction, When brushing is not in the same place repeatedly brushing to avoid the formation of a gel. Tube roots, fell into the water with a scrubbing brush and other special parts. D: After the glue with the primary coil, dry to dry binder base, generally by hand is not bonded to perform paving. 4 Paste roofing membrane: A: From the start flowing downhill slope, the pop standard line, coil configuration should be longer perpendicular to the slope with water. B: Whenever Puwan roll sheet immediately after the brush with long soft roll from one end toward the membrane lateral force rolling again, with the primary coil to completely exclude the wear between the gas. If you can not rule out the begging bubble, do not cut the membrane to exhaust themselves, so as not to affect the overall waterproof effect. C: membrane bonded joints Caution Do not shop in the frozen surface of the base note self-adhesive membrane; can not be contaminated and the high moisture content of the grass-roots construction; self-adhesive membrane separator paper packaging and only in the shop Thes posts when removing and paving; sealant runs out at the end, should be promptly screwed tightly sealed container; storage and transport of materials in a dry, ventilated storage environment, to prevent the sun and rain. Different types, sizes membrane should be piled separately. Stack height does not exceed 5 layers as well, heel no more than 2 layers.
