3. Product Application:
a. Make sure the base surface smooth, clean and dry(Moisture<9%), then paint the delicated agent on the base surface. Start application till it is dry.
b. Reinforce the parts which are easy to leak, such as seam, hole, channel, wall, pipe and corner.
c. Application Method:
Lay the membrane directly. Be careful to control the overlaps of the long side and short side.
d. After application, a careful inspection is required. Make sure there is no air bubble, no fold, no falling away etc to guarantee the waterproof life.

- Q:What is the meaning of "channel" and "layer" in the practice of polymer waterproofing membrane?
- In addition, the two did not meet the required thickness of the waterproof layer, according to certain requirements for laminated composite, two waterproof layer can be considered a waterproof. Such as 1.2mm polyurethane + 1.2mm self-adhesive coil (laminated construction rather than separate), can be used as a waterproof, although with two kinds of materials to do a two-story waterproof, and can not be considered two waterproof. The thickness of the laminated composite waterproofing layer can be thinned, and its provisions may be reflected in the new "roofing engineering technical specification" to be published.
- Q:DTM.E polyester composite waterproofing membrane, cheaper than the asphalt membrane?
- Ouwei Jianke DTM.E polyester composite waterproofing membrane is the company according to GB50207-2002 "roofing quality acceptance norms", GB50108-2008 "underground engineering waterproof technical specifications", GB50208-2002 "underground waterproofing project quality acceptance norms" and Other waterproof engineering design Widely used in a new type of waterproof material,
- Q:How to distinguish whether the waterproofing membrane is polyester tires?
- Polyester tires (polyester fabric, polyester felt, polyester linoleum fabric) with high strength, high extension and puncture resistance, light weight, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion. Technical requirements, including the appearance of quality, intrinsic quality assessment projects and internal quality reference project, the indicators are in line with the provisions of the waterproof standards. Routine project tests should be in accordance with national standards test methods, thermal stability, bending, impregnation, water resistance test methods have done a detailed test.
- Q:How to use self-adhesive waterproofing membrane?
- 1) grass-roots treatment: grass-roots surface should be treated first, so that the grass-roots solid, clean, and fully moist, no water.
2) wiping cement (waterproof) mortar: its thickness is generally 10 mm ~ 20 mm (depending on the level of formation may be), paving should pay attention to compaction, smoothing. In the corner, should be wiped into a radius of 50mm or more fillet. Paving the thickness of cement mortar than the length of the coil, short side should be wide out of 100 ~ 300mm, and in the process of spreading the use of rail to ensure smoothness.
3) peel off the self-adhesive waterproof membrane under the surface of the isolation film.
- Q:The shortcomings of polypropylene waterproofing, and the shortcomings of modified asphalt waterproofing membrane
- The advantages of the membrane waterproof, such as: the construction is convenient, the construction period is short, not need to be cured after forming, is not affected by the temperature, the environmental pollution is small, the layer thickness is easy to hold and hold the fortification meter, the material is calculated accurately, the site management is convenient, Cut corners, even thick layer, empty shop can effectively overcome the grass-roots stress (effective in the grass-roots cracks to maintain the overall waterproof layer).
- Q:What is the meaning of the node and the additional layer in the construction of the membrane waterproofing layer?
- Additional layer refers to the large area before the construction of the node parts of the pre-treatment, need to strengthen the protection of these weak links in advance, generally do more than a layer of coil.
- Q:What are the requirements for the storage of waterproofing membranes?
- Stand up to release the time can not put too long or how you put the deformation will be ..... so we generally stand
- Q:Pvc waterproof membrane of the scope of application
- 3, with good weldability, seam hot air welding and the substrate into one;
4, with good water vapor diffusion, condensate easy to release;
5, low temperature flexibility is good, to adapt to the environmental temperature difference is good;
- Q:The difference between high polymer modified asphalt waterproofing membrane and sbs
- SBS modified asphalt waterproofing membrane is a kind of polymer modified asphalt waterproofing membrane, which is included with the included relationship.
- Q:What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
- BAC refers to butyl acetate, BAC waterproofing membrane is a composite double-sided self-adhesive rubber asphalt waterproofing membrane, the coil material in the polymer (chain) and cement hydrate (silicate network) (Interfacial) interpenetrating network (IPN) structure, cement can be flow, infiltration or impregnation, solidification strength increases, the cohesive force increased. The leakage caused by the damage caused by the coil can be limited to the local scope, to avoid leading to the overall failure of the waterproof layer. BAC composite self-adhesive waterproofing membrane elongation performance, with a unique self-healing function, can self-healing smaller puncture damage, can automatically fill the smaller grass-roots cracks.
