- Construction can also be used to produce waterproof pulp, waterproofing agent for the amount of cement 3 ‰ -4 ‰, the use of cement label not less than 32.5MPa.
- Q:Can acrylic materials be perforated? How to do waterproof after punching?
- It is best not to drill in the finished product on the screen, if it is absolutely last resort,
You can use fiberglass material in the hole position paper;
- Q:Waterproof mortar expensive or dry mortar expensive
- Dry mortar is usually called hydraulic cement mixed mortar, refers to the dry sieve treatment of aggregate (such as quartz sand), inorganic cementing materials (such as cement) and additives (such as polymers) and so on a certain proportion of physical mixing Into a granular or powdered, in the form of bags or bulk transported to the site, add water, mix directly after the use of materials.
- Q:A complete set of basement waterproof construction program
- First, the basement of the external walls of water leakage project engineering basement waterproofing standard GB50108-2001 "underground engineering waterproof technical specifications" secondary waterproof rating. Basement exterior wall waterproof structure with self-waterproof concrete plus coil waterproof, 50 thick polystyrene board protective layer.
- Q:How do you make waterproofing in the kitchen and bathroom?
- Kitchen and toilet is a relatively stable part of the home improvement structure, it is recommended to do waterproof mortar waterproofing agent on it, mortar waterproofing agent not only with the base surface bonding firm, and puncture resistance, high strength, waterproof life and construction Material with the life, the construction of relatively waterproof coating is also relatively simple.
A barrel of 20KG mortar installed on the ground can be about 5 square feet, the wall can be done about 10 square feet, the price is relatively high. But to remind, must be in accordance with the product description on the process to match and construction, so as to ensure that once and for all the waterproof effect!
- 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:Oriental rain rain waterproof how to
- 2, Oriental rain rain waterproof coating application If the above content can not accurately explain the East rain rain waterproof paint is good, then continue to look at the East Rainbow waterproof coating since the application of this Examples, I believe that most consumers can not say. Oriental Yuhong waterproof coating with its excellent product performance is applied to the Great Hall of the People, China Millennium Monument, the Three Gorges Hydropower Station, Beijing Metro, Capital Airport, Beijing Wuhuan, Sixth Ring, Beijing-Shanghai high-speed, directly under the central grain depot, China Central Television, National Aquatics Center (Water Cube), National ...
- Q:Find the construction steps for waterproof coatings
- 1, base surface treatment
(1) roof structure After the completion of concrete pouring, should be repeated water compaction, so that the surface of the grass-roots level, the flatness with 2m to check the ruler, ruler and grass-roots gap of not more than 5 mm, and only allow gentle changes.
(2) the base surface of the pores, rugged, honeycomb, gap, sand, etc., should be promptly treated, the base surface must be clean, no floating slurry, no water beads, no water; when the base surface appears more than 0.3 mm cracks , Should rush each 10 cm brushing 1 mm thick polyurethane coating waterproof layer, and then set the polyurethane cloth reinforcement layer, and finally brushing waterproof layer.
(3) all the corners are used 5 × 5㎝ 1: 2.5 cement mortar for chamfering, the angle made R = 10 mm rounded corners.
