Although there are many waterproof coatings on the market and on the Internet, such as "two-component polymer waterproof coating" and "one-component polyurethane waterproof coating"... the name is professional and there are many kinds, but if it is divided according to nature, it is currently on the market. There are only 4 kinds of indoor waterproof coatings for sale, and they have different performances, each with advantages and disadvantages. Hard mortar, also known as rigid mortar: the ratio of emulsion to mortar is 1:4. It is not necessary to treat the coating after brushing, and it can be directly tiled, which is 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. Price: 200-300 yuan / barrel, a barrel of 18 kg, can brush 10-13 square meters. 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. Price: 300-500 yuan / barrel, a barrel of 18 kg. There is also a kind of silica gel waterproof coating in the flexible mortar. It belongs to high-grade flexible mortar. The elastic tension and flexibility are very good, but the price is 600 yuan / barrel, which is relatively expensive and is very rare on the market. Acrylate: pure liquid, ready to use. Water-based, meltable in water, easily combined with the ground gap to form a strong waterproof layer, waterproof effect is better than flexible mortar. After brushing, it is necessary to carry out surface treatment such as pulling or sanding to increase friction and to easily affix bricks. Due to the excellent water resistance, flexible mortars and acrylates are more suitable for use in long-term water immersion environments. Price: 300-500 yuan / barrel, a barrel of 18 kg. One-component polyurethane: both indoor and outdoor, brushed very thick, about 3 mm, and the elastic tension is more than 300%, very elastic, no cracking of any substrate will cause it to crack, the best waterproof effect. 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 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. After brushing the paint, it needs to be surface treated, brushed or sanded to increase friction and easy to tiling. Price: about 500 yuan / barrel, a barrel of 18 kg. The drying speed of these coatings is affected by the weather, and the drying speed is slower in cold and cold weather conditions, but the climate has no effect on the waterproofing effect. In general, the drying period of the mortar is 24 hours, and the drying period of the acrylate and polyurethane is 24-48 hours. "One-component", "two-component" difference: mortars are two-component polymers, that is, the ratio of emulsion to mortar; acrylate and polyurethane are not used in mortar, it is a single component. Handle the base layer before painting The coating of waterproof coatings has a lot to do with the condition of the ground base. The more uneven the base layer, the more paint is used. Therefore, before applying the waterproof coating, it is best to simply treat the base layer and smooth the base layer as much as possible. Secondly, it should be ensured that the ground is dust-free, soil-free, and oil-free. The mop can be carefully mopped to remove all the dust. Otherwise, the waterproof coating will be cracked and the waterproof effect will be affected. Door Accessories
