How to choose waterproof coating
In fact, the main cause of water seepage and water leakage in many bathrooms is caused by the unqualified waterproof coating used. At present, there are no more than 100 kinds of waterproof materials on the market, which are mainly classified into polyurethanes, cement mortars, acrylics and polymer polymers. Polyurethanes are now close to being eliminated due to their non-environmental protection. As one of the emerging waterproof materials, cement mortars are moderately priced and have good waterproof performance. They are currently very popular materials for sale. However, the solidity of the sand ash may also cause cracks due to the tiny settlement and dislocation of the building, causing leakage in the future. Therefore, when selecting such products, you need to carefully select them.
The biggest feature of acrylic material is that it can be diluted with water to be a water-soluble material and it is colorless and odorless. This material is followed by an exceptionally dense waterproof material with conspicuous elasticity and ductility so that it does not fracture with the settlement and dislocation of the substrate. However, this material is currently more expensive, and building materials supermarkets generally cost more than 300 yuan. Polymer polymer coatings have many good ductility and elasticity. At the same time, they are colorless, odorless and environmentally friendly. However, its disadvantage is that any slight bumps and contact will cause damage to the waterproof membrane and no thickness can be brushed. The use of talcum powder in combination reduces the elasticity. At the same time, the prices of these materials are also relatively high, and the overall price is around 250-300 yuan.
What should waterproof coating do?
After doing grassroots, we should start to do waterproofing. In general, when it comes to waterproofing, everyone thinks that it is sufficient to buy materials. In fact, if the grassroots is not good, no matter how good the material is, it will not guarantee the effect of waterproofing. Therefore, the grassroots must not sand, no cracks, flat, no empty drums; different materials have different requirements for the wetness of the base; if the ground slotted pipe must be repaired before the waterproof layer can be done. The quality of the waterproof layer of the bathroom requires that the thickness of the waterproof layer should not be less than 1.5mm; the amount of waterproof material should not be less than 2kg per square (waterproof coating). During construction, care must be taken to ensure that the thickness of the waterproof layer or the amount of water-repellent material used is sufficient to ensure the thickness of the waterproof layer. The waterproof layer reaches the specified thickness to ensure the true effect of waterproofing.
