News: waterproof layer in the system is set up as close to the source of water or moisture, that is, facing the water, but also should consider the feasibility and convenience of construction. Most of the waterproof layers used in building ceramic finish systems are laid between the flat layer and the ceramic adhesive layer, so the
waterproof coatings selected
must be very compatible with the flat layer and adhesives, mainly reflected in the full, durable stretch bonding strength between each other. Too high fracture elongation in this system does not have a better effect, weather resistance, UV resistance, etc. do not need to be considered in this system at all.
there may be many types of building ceramic finish systems that need to be considered for waterproofing, in addition to the wide variety of geometry of the waterproof position, as well as a variety of water supply and drainage pipes and ground leakages that penetrate the waterproof/moisture-proof layer. In the selection of waterproof
coating
should be based on the detailed design of the detailed construction, and refer to the paint manufacturer's technical instructions. In addition to considering the physical and mechanical properties of waterproof coatings themselves, the specific circumstances of specific projects should also be considered in detail. For example, in long-term immersion areas such as swimming pools, in addition to the basic performance of waterproof coatings, water-resistant coatings should also be considered in the long-term sustained moisture can not appear soluble and other phenomena. Because once the swelling occurs, it may cause local waterproofing failure under water pressure or other external forces.
paint thickness of the waterproof coating shall meet the design requirements and shall refer to the technical instructions of the paint manufacturer. In the grass-roots deformation volume is large, the service environment vibration is frequent, the flat layer has the risk of cracking, waterproof coating should choose polyester mesh cloth or alkali-resistant glass fiber mesh cloth as the tire body enhancement material.
