1) Introduction of  ceiling roof material

  1.    Breathable Membrane is a water resistant membrane but with high vapour permeability, use as diffusion open roofing felts under pitched roof tile or vapour permeable barrier housewraps on timber frame walls

  2.    Breather membrane functions as a weather-resistant barrier, preventing rain from getting into the roof or wall assembly while allowing water vapor to pass to the exterior.

  3.    Breather membrane may also serve as an air barrier if it is sealed carefully at seams.

  4.    Breathable Membrane have good "water resistance", good "water vapor permeability", and good "air barrier properties".

Q:There is no formaldehyde in the finished putty
The current status of the market to buy regular manufacturers out of semi-finished products putty and formaldehyde has nothing to do, because the status quo countries also hit the product containing formaldehyde in the building materials, the current market traffic is relatively large for the water putty, putty powder which is natural mineral powder And water-based glue synthesis, because the product life long-term pollution-free, so that is impossible to contain formaldehyde, but engineering putty is usually on-site modulation, and in order to increase the adhesion of putty powder inside the addition of a large number of construction glue (Containing formaldehyde).
Q:I would like to ask how to do in the warm water above,
1, I think the flexible mortar, waterproof paint better, because these materials in the construction process, not to warm the temperature caused too much impact, if the shop waterproofing membrane is too heavy, may affect the warm heat. 2, generally in the floor before the warmth, first do a waterproof, paved to warm to do once.
Q:What are the key points and contents of the quality control of waterproof material?
2, ordinary two-component polyurethane: A material is similar to the appearance of edible oil translucent yellowish curing agent from polyether and isocyanic acid by polycondensation of polyurethane prepolymer (about 20,000 yuan / t), B material For the plasticizer, coagulant, fillers and other components of the black liquid (about 3900 yuan / t), after mixing the polyurethane coating is also black. But also because of A, B material of the huge spread so often the following two kinds of fraud: ① with a very cheap black oil (priced at only about 1,200 yuan / t), diluted with xylene after thin coating twice. Cold oil is not easy to dry after the coating, after each coating must be drying a few days, in the winter with roasted, and then do not sprinkle dry powder cement, so a long time paint are dry. ② is often used to expand the proportion of A, B components such as 1: 4-6 (usually 1: 2), but also in the polyurethane mixing process by adding cement powder as a filler, if the stirring is not added xylene diluted Agents and other methods of fraud.
Q:Why should the use of high pressure perfusion waterproof plugging method
Due to uneven settlement of buildings and other factors, resulting in deformation of the building structure cracking, leakage phenomenon, for the repair of this situation, you can use a new foreign plugging construction technology - high pressure grouting waterproof repair technology.
Q:Waterproof material water leakage construction should pay attention to what
Or to local, if it is a bathroom, it should pay attention to these points: Bathroom waterproof practice: 1, ground handling Before the water treatment, must first find the ground. Leveling layer of construction methods: the base surface with gaps, cracks, unequal defects, with cement mortar repair smooth. So that the base surface must be strong, smooth, clean, dust-free, greasy, wax, release agent, and other debris material. Leveling layer before drying can be waterproof construction, construction should be fire, waterproof. After the completion of the waterproof layer, to be finished product protection, not on the move.
Q:What material waterproofing can be mixed with cement sand
Waterproof layer used in the cement label of not less than 32.5MPa, the thickness of cement mortar should be 2-3cm, the surface clean and solid without cracks; mortar leveling layer of cement should not be less than 32.5MPa, leveling layer to smooth compaction, finished product maintenance is not low In 5 days.
Q:Find the construction steps for waterproof coatings
3, note (1) rain weather and five wind above the weather shall not be construction. (2) coating waterproof layer shall not have bottom leakage, cracking, holes and other defects and peeling, bubbling, carcassing and wrinkle phenomenon. Coating waterproof layer and the base should be bonded between the solid, no hollowing, trachoma, delamination and so on. (3) the coating site should be continuous, solid, shall not appear Alice, hollowing parts. (4) rigid protective layer before the completion of any personnel shall not enter the construction site, so as not to damage the waterproof layer; coating of the overlapping parts should be care by the staff. (5) roof should be used lime soil, clay or sub-clay for backfill, thickness 50 cm, backfill shall not contain stones, gravel, ash and organic matter. Artificial compaction of each layer 25 cm, mechanical compaction of each layer 30 cm, rammed to prevent damage to the waterproof layer. In the backfill thickness of more than 50 cm, it is allowed to use mechanical backfill rolling.
Q:Self-built concrete house finished three years after the use of large-scale housing wall leakage how to do?
Third, from the indoor water leakage area for waterproof maintenance.
Q:Roof sunscreen waterproof layer leakage, brush milk white plastic can solve it?
How to deal with the roof leakage, the roof leaks to find the first leak, looking for the main leak from the roof to the lower to find leakage. The first is to see if there is no cracks in the roof, the original waterproof layer is not aging, the roof of the original SBS waterproofing membrane has no bubbles, there are bubbles to prove that the water has entered the bottom of the waterproof layer, and thus leaking. There is a block on the roof of the gutter is not blocked in the countryside, there are still a large number of tile-roofed house, when the tiles due to damage caused by the roof leakage, as long as the replacement of tiles can be, this step is also known as "
Q:How do you make waterproofing in the kitchen and bathroom?
Fatty acid cement mortar waterproofing agent; integrated current domestic and foreign new waterproof material of the latest technology, in the original polymer cement mortar waterproofing agent developed on the basis of raw materials imported from Germany, the higher fatty acid materials, by more than 20 kinds of raw materials by the special complex Chemical reaction of water-based emulsion, a new type of fatty acid cement mortar waterproofing agent.
