Coating knowledge: three steps of waterproof coating

Core tip: [news] there are two kinds of waterproof materials for home decoration sold on the market: one is modified asphalt waterproof coating with glass fiber cloth, which can improve the strength and flexibility Using this kind of coating, the waterproof project is more complicated, but the price is not high, about 100 yuan per square meter; the other is polyurethane waterproof coating, which is a high-grade waterproof coating with polymer film at present This kind of coating has good waterproof effect, but its price is high The price per square meter is about 140 yuan During waterproof construction: Step 1: place the base course first Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: [news] there are two kinds of waterproof materials for home decoration sold on the market: one is modified asphalt waterproof coating with glass fiber cloth, which can improve the strength and flexibility Using this kind of coating, the waterproof project is more complicated, but the price is not high, about 100 yuan per square meter; the other is polyurethane waterproof coating, which is a high-grade waterproof coating with polymer film at present This kind of coating has good waterproof effect, but its price is high The price per square meter is about 140 yuan In waterproof construction: the first step: the base course should be treated first Remove the original decoration materials, clean the floating soil and cement, and make the surface flat and dry Step 2: lay waterproof coating Brush a layer of modified asphalt, a layer of glass cloth on the base course for waterproof treatment, and then brush again Finally, brush a layer of paint on the second layer of glass cloth, and the waterproof treatment is completed The waterproof coating shall be brushed evenly, the glass cloth and the waterproof layer shall be sealed tightly, and there shall be no leakage, bulging and falling off, otherwise the waterproof effect will be affected If polyurethane is used as waterproof coating, glass cloth is generally not needed, as long as it is repeatedly brushed for 2-3 times Because polyurethane coating itself can form elastic protective film, which has certain tensile resistance In order to improve the waterproof effect, a layer of glass silk cloth can be paved, but the cost will increase It should be noted that when making the ground waterproof, the waterproof coating and glass cloth should be brushed to the wall 20-30cm away from the ground to prevent the leakage of the connection between the wall and the ground, so as to form a closed and solid overall waterproof layer For the wall of shower room, soft light wall and indoor wall that is afraid of leakage, it is necessary to apply waterproof coating to the wall 1.8m or full wall to prevent the wall from leakage The third step is to do the "water shielding" test, which is an important test method to test the indoor waterproof quality After the completion of the waterproof project, the door and the water outlet shall be sealed, and the indoor water storage shall reach a certain liquid level height If the liquid level does not drop significantly within 24 hours, it is qualified After the completion of the "water covering" test, another layer of cement mortar protective layer shall be made on the waterproof coating layer, taking care not to damage the prepared waterproof coating layer After the cement mortar protective layer is dry, it can be paved with wall tiles or sprayed with paint for normal decoration Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
