< --d ---d --d ---dd ! ： Basic requirements for grassroots workers The thick leveling layer made of: cement mortar should be smoothed and calendered, solid, flat, sand-free, and should not have convexity, looseness, bulging, pitting, etc. The flatness should be checked with a long ruler. The gap between the leveling layer and the ruler should not exceed 10%. The surface of the leveling layer must be dry. The cement mortar should have sufficient strength and its moisture content should not exceed %.
< --d ---d --d ---dd ! : The connection and corners between the leveling layer and the protruding roof structure (parapet, chimney, etc.) should be made into an arc shape with a radius of A slightly lower depression should be made around the drain outlet to facilitate drainage. ->
< --d ---d --d ---dd ! D: The slope and pan of the leveling layer should not meet the design and relevant regulations. ->
< --d ---d --d ---dd ! .Process flow: Cleaning the base layer, additional layer treatment, surface gluing of the roll material, bonding of the base layer, surface gluing roll, exhaust compaction roll End closing and edge sealing treatment to create a protective layer ->

< --d ---d - -d ---dd !: Clean the base layer: The base layer that has passed the inspection before construction will be cleaned again. ->
< --d ---d --d ---dd ! :Additional layer: Special parts such as yin and yang angles, pipe roots, drain openings, etc. must first make additional layers. It can be coated with polyurethane or laid with a roll material. ->
< --d ---d --d ---dd !: Apply glue to the base layer and the surface of the membrane: Spread the membrane on the clean base layer and use a long roller brush dipped in neoprene adhesive Apply evenly on the coiled material and then apply it on the base layer. When painting, do not paint the same place multiple times to avoid gel formation. Special parts such as pipe roots and drain openings should be painted with a board brush. ->
< --d ---d --d ---dd ! D: The roll material and the base layer are glued and allowed to dry until the adhesive is basically dry. Generally, paving can be carried out without bonding by hand. ->
< --d ---d --d ---dd ! . Pasting of roofing membrane: ->
< --d ---d --d ---dd ! : The configuration of the standard wire coil that starts from the downhill slope of the flow slope should be perpendicular to the direction of the flow slope. ->
< --d ---d --d ---dd !: Whenever a roll of roll is laid, a soft long-handled roller brush should be used starting from one end of the roll and moving across the roll. Roll it hard once to completely eliminate the air leakage between the membrane and the base layer. If begging bubbles cannot be eliminated, do not cut the membrane and exhaust it yourself to avoid affecting the overall waterproofing effect. ->
