- 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:I am referring to the amount of dry mortar that is not stirred
- The middle of the foam board, both sides of the barbed wire grid Mostly used in furniture, electrical appliances <within the packaging, pad, in order to prevent damage in the process of handling finished products> inside and outside the building from the role of insulation EPS board (also known as benzene board) is made of polystyrene board abbreviation It is made of raw material through pre-hair, ripening, molding, drying and cutting It can be made into different density, different shapes of foam products, but also can produce a variety of different thickness of the foam sheet Widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields Can also be used to display the venue, merchandise cabinets, advertising signs and toys manufacturing bonded mortar with high quality modified special cement and a variety of polymer materials, packing by a unique combination of technology, good water retention, paste the high strength, construction is not falling Has excellent weather resistance, impact resistance and crack resistance Mainly used for polystyrene board and rock wool board, extruded board and other insulation board wall, wall and ceiling bonding
- Q:What is good for roof waterproofing? Coil or waterproof paint ah?
- Because the roof needs long-term sun and rain erosion, so we recommend the need for rigid waterproof + flexible waterproof combination of construction, that is, first brush a K11 waterproof slurry, and then do a protective layer of mortar waterproofing agent, so that can meet the roof Waterproof demand.
