What are the characteristics of home improvement waterproof materials and their characteristics

The use of waterproof materials for home improvement is indispensable during home decoration. Some places where water environment is often used, such as kitchens, balconies, bathrooms, etc., need to be waterproofed with waterproof materials. So what are the common home improvement waterproof materials and their characteristics.

First, flexible mortar

The ratio of emulsion to mortar is 5:4, which has elasticity. Even if the base layer is deformed and cracked, it will not affect the waterproof effect. It is mostly used for water-facing surfaces such as walls and floors. It can not be used for the back surface such as the top surface. If the waterproof is not done well, there is water penetration, and it is easy to get water seepage.

Second, polyurethane

Both indoor and outdoor, the brush is very thick, about 3 mm, and the elastic tension is more than 300%, very elastic, any cracking of the substrate will not crack, the waterproof effect is best. Although the safety performance is controlled by environmental protection requirements, the odor of such waterproof coatings is large, which is difficult for ordinary people to accept, and the environmental performance of very few waterproof brands is not up to standard. The polyurethane is gelatinous and thick, and it requires a scraper during construction. It is very laborious and complicated.

Third, hard mortar

Also known as rigid mortar: the ratio of emulsion to mortar is 1:4, no need to treat the coating after brushing, can be directly tiling, more convenient. After solidification, the cement lumps are formed, and the water-repellent effect of the water surface is good, which is the biggest advantage. The disadvantage is that the mortar has a high hardness and is easily cracked as the base layer is cracked, so it is generally used for waterproofing the back surface.

Fourth, the coil category

At present, there are also some decoration companies to use! The advantage is that the price is low, the waterproof effect is not bad!

Most waterproof coatings on the market are water-soluble materials, and various businesses have also claimed that water-soluble waterproof coatings are environmentally friendly materials, and most of them are called oil-soluble waterproof coatings that are not environmentally friendly. In fact, whether it is water-soluble or oil-soluble waterproof coating, as long as the country has passed relevant environmental certification, such as China Environmental Labeling Certification or CTC product environmental protection, quality certification, etc., these materials are environmentally friendly and reliable.

Five, acrylate waterproof coating

The acrylate waterproof material is a pure acrylate copolymer or a pure propionate emulsion, and is added with a proper amount of high-quality filler and auxiliary agent, and is a synthetic resin one-component waterproof coating. For water-soluble paints, it can be diluted with water. It has greater elasticity and ductility after conjunctiva. The waterproof effect is remarkable, the price is moderate, and the home decoration is preferred. However, there are only some large decoration companies in the decoration company. Compared with it, it is still The price is high!
