Q:What are the general types of waterproof materials, the number of years of use?
Waterproof material is divided into the first category from the above, there is a flexible waterproof material and rigid waterproof material 1. Flexible waterproof material is divided into waterproof membrane waterproof coating sealing material 2. Rigid waterproof material is roughly divided into silicone waterproof material fatty acids Waterproof material is also commonly used in the waterproof membrane SBS, APP, TPO, waterproof coating is also divided into K11 general type, K11 flexible type, JS, rigid waterproofing is the most common mortar waterproofing agent The This is a lot of factors related to, such as whether the standard construction, the thickness of the waterproof layer, waterproof layer of the latter part of the protection, but one thing is certain is the mortar waterproofing agent Water resistance is relatively long for waterproofing materials.
Q:What is EVB insulation mortar? Heard a lot of counterfeit, in Guangxi, where can buy genuine,
With the light, heat, fire, high and low temperature resistance, anti-aging, low water absorption and other characteristics, can replace many traditional light orthopedic applications in different products Is a kind of environment-friendly high-performance new inorganic lightweight insulation materials Can be widely used in industry, agriculture, chemicals, metallurgy, building materials, medicine, light industry and many other areas EVB thermal insulation fire mortar is EVB particles as inorganic thermal insulation fire mortar lightweight aggregate, it is pre-mixed with high-quality cement in the polymer modifier, the formation of one-component thermal insulation fire dry powder mortar ; Products with excellent thermal insulation function, anti-aging weather resistance and fire function, no hollowing cracking, high strength, bonding, anti-sagging performance, pest control ants; construction convenience, on-site construction can be used to stir , Can be directly built in the wall inside and outside the wall In Guangxi Qinglong can buy genuine, "EVB" is a registered trademark of Guangxi Qinglong company, to buy Guangxi EVB insulation mortar to look after the dragon trademark
Q:Bathroom to do with the East Yuhong waterproof material, but also with waterproofing agent to do waterproof layer?
First, the East Rainbow is just a waterproof material brand, followed by different home improvement parts need to choose a different waterproof material, some suitable for rigid waterproof, such as kitchen and bathroom; some need to rigid combination such as roof or balcony. And your question did not ask very clearly, so bad answer.
Q:What is good for the waterproofing layer of the outer wall of the basement?
masonry wall, the best, but pay attention to the wall to build the bottom of the structure of the bottom plate to prevent the foundation settlement caused by the protective wall and the relative sliding between the waterproof layer
Q:How to install squatting pan? Need to pay attention to what matters?
Patented safety squatting pan installation height with a trap within 250MM.
Q:Insulation putty can be used alone as an external wall insulation material? Whether the external wall insulation putty can replace the external wall mortar
First of all, you can not replace the insulation material insulation, and many products in the development process slowly with the time will reflect their own shortcomings, insulation board has now been recognized by the state, and Insulation putty is not able to achieve the quality of the real ability to quantify. Insulation board normal life can reach 20 years, up to 30 years, the life of insulation putty is also 20 years, high water resistance can reach 30 years. Insulation putty can not be too thick construction, too thick easy to crack off, large area with the visual plane effect is poor. And the insulation board in the thickness of the greater arbitrariness, the insulation board in the construction of Ji Ji reclamation killing the old ghost tame handmade foam can make a large area of ​​the wall is more smooth, of course, relatively heat putty, the construction cost is higher. But the two are complementary in the building, a small area more difficult to build the edge of the construction site, available insulation putty, large selection of insulation board, of course, for some of the insulation requirements are not high can also use insulation putty. The insulation requirements of a little more choice of insulation board. Insulation putty can replace the mortar, the premise is not to do other work above the putty. I hope my answer will help you!
Q:Sticky benzene board with mortar for each square about how many kilograms ah?
sticky benzene board with mortar per square meter with about 0
Q:Basement wall wipe 20 thick PG waterproof mortar, what is "PG waterproof mortar"?
Type: the market used in the construction industry in the species is still relatively rich, generally according to its production process in the addition of the chemical composition of the different waterproofing agent, the market can be divided into the following four categories: 1 , Chloride metal salt waterproofing agent;
Q:Choose epoxy mortar floor, looking for epoxy mortar floor construction program
Epoxy mortar floor, widely used in machinery, electronics, chemicals, medicine, tobacco, textile, furniture, light industry and other manufacturing plants and warehouse floor, its ultra-high strength, wear resistance, beautiful and durable, Texture, solid, easy maintenance, etc
Q:JS waterproof paint how, advantages and disadvantages of what are each?
JS composite waterproof coating is the introduction of advanced technology and key raw materials, organic liquid and inorganic powder compound made of two-component waterproof material. The main features are: . wet surface construction; coating tough high strength. . add the pigment can be made of color decorative layer. . non-toxic, tasteless, can be used for water consumption of the pool. . for a facade material wall, inclined roof of the waterproof, facade, slope and the top of the construction, with the base and facade brick, roof tile, cement mortar and other outer material firmly bonded. . high temperature (140 ℃), especially for road and bridge waterproof. . adjust the mix ratio, can produce ceramic tile bonding materials and sealing materials. Construction process: . the base surface requirements of flat, solid, clean, no water, no leakage, rugged and cracks must first leveling, yin and yang angle should be made arc angle .. accurate ingredients: The product has been strictly in accordance with the requirements of the packaging requirements, the use of powder only while stirring slowly added to the corresponding liquid material, and fully stir to the uniform and delicate mixture without particles. . coating essentials: ① with a roller or brush coating, according to the order of the selected method to complete the layer.② If the paint (especially the primer material) precipitation should be synchronized at any time. ③ coating should be as uniform as possible, Can not be localized. ④ The interval between the layers before the layer of dry film is not sticky ⑤ ⑤ ⑥ method Ⅲ in the lower coating, non-woven layer and the coating must be continuous construction. And other waterproof material The difference is really bad to say because the waterproof material at least one hundred different kinds of the difference may be great I am not a professional waterproof also said that is not clear
