All construction coatings have passed ISO9001 Paint Home News: the main guarantee in the process of home decoration is safety work, such as waterproof, circuit installation, waterway installation, etc First of all, we should choose high quality waterproof coating for home decoration waterproof work, and then carry out construction 1、 Standard construction to ensure the quality of waterproof coating construction process selected waterproof coating, does not mean that home waterproof is foolproof As the saying goes, "three materials, seven construction", if there is a mistake in the construction, it will bring a lot of trouble Therefore, it is necessary to understand the standard process of waterproof coating construction, whether self-assembly or construction by personnel, to minimize the risk of water leakage 1 Construction preparation: do a good job in base treatment waterproof base requirements: before waterproof construction, do a good job in the base treatment of wall and ground, to ensure that the base surface is solid, without cracking, pulverization, peeling, bulging and other phenomena At the same time, the surface of the base course must be clean, free of dust, film remover and other impurities that affect the adhesion of the paint Treatment method of base course: generally, the base course shall be cleaned carefully to remove floating dust, cement caking and loose base course; special treatment shall be carried out for pipe root, drainage hole, internal and external corners, holes left after water and electricity transformation on the wall, etc., and the internal and external corners shall be plastered into circular arc (or V-shaped) Uneven and cracked parts need to be repaired and leveled 2 Construction preparation: in the past, only a simple brush is needed to prepare the waterproof coating according to the proportion Now, the new waterproof coating is mostly two-component or even three-component Therefore, before construction, it is necessary to know how to allocate and what proportion to allocate If not proportioned, the prepared waterproof coating may not achieve the original effect 3 Brushing method: the waterproof coating on the wall first and then the ground is similar to the general liquid coating, from the bottom to the top, from the wall first to the ground When using, if there are bubbles in the slurry, it is necessary to brush the bubbles, and there should be no bubbles The first painting needs to be done in one direction only, and the second painting needs to be done in the opposite direction The interval time between the first and the second brushing should be about 4-8 hours 4 Special treatment: the sanitary ware for caisson treatment needs to be backfilled Many sanitary rooms are generally caissons, so it needs to be backfilled Before backfilling, it is generally required to make a waterproof, and then make backfilling after closed water test After backfilling, level and make another layer of waterproof 5 Construction standard: Generally speaking, the waterproof height and thickness of bathroom is 180cm, and the waterproof coating of non shower wall should not be less than 30cm in principle But in order to strengthen the waterproof function, it is recommended to achieve a unified height of 180cm In addition, for the light body wall and self built light body wall, it is suggested that the waterproof height should be at the top In terms of thickness, the waterproof coating must be brushed to 1.5mm of the national acceptance specification 2、 The acceptance test can't be short of the waterproof construction acceptance method Once the waterproof works leak and repair, the work quantity is very large For example, for the waterproof repair of the bathroom, first of all, the wall tiles and floor tiles should be removed, the waterproof work should be done again, the wall to floor rotation should be done again, and the toilet, shower room and ceiling should be installed again This is a double pass project Therefore, it is very important to check the quality of waterproof engineering 1 Closed water test is indispensable Closed water test is an important work of waterproof inspection For the original waterproof layer, through closed water test, we can know whether the waterproof layer is in good condition, whether it needs to be repaired, and whether it is necessary to redo the waterproof layer The new waterproof layer can be used to check whether the waterproof construction is qualified 2 General practice of closed water test The closed water test can only be done after the waterproof coating is completely dry First, the prepared sand shall be put into the plastic bag, and the floor drain shall be blocked tightly to prevent the accumulated water from running away; then the door that may be full of water shall be blocked with cement; Then drain the water The water should be soaked in the whole closed water test ground Generally, 10cm is enough If the water that is afraid to drain evaporates in the next 48 hours, 20cm will be put 3 Judgment standard of closed water test The closed water test time is at least 24 hours in summer and 48 hours in winter During this period, observe whether the water surface drops significantly, especially whether there is leakage on the roof of the downstairs house to check whether the waterproof construction is qualified The light wall shall be subject to water sprinkling test The water pipe shall be used to spray the wall for 3 minutes from top to bottom After 4 hours, observe whether the other side of the wall will have seepage phenomenon If there is no seepage, it can be considered that the waterproof construction is qualified 4 Details of closed water test operation Pay attention to the following points when doing the closed water test: first, the floor drain must be blocked tightly If the terrain is the same, the cement should be blocked at the door, and then the water should be drained after the cement is dry; secondly, when the water is drained, a basin or cover should be placed on the place where the water column directly contacts the ground to prevent the water-proof layer from being damaged by too strong water pressure 5 Treatment method for unqualified closed water If the closed water test fails, the waterproofing works must be redone as a whole before acceptance Other construction can only be carried out after passing the acceptance 6 Understand the warranty period of house waterproofing The waterproofing of general houses is constructed by the decoration company According to Article 32 of the management measures for interior decoration of houses, under normal use conditions, the minimum warranty period for interior decoration of houses is two years, and the minimum warranty period for kitchens, bathrooms, external walls and anti leakage with waterproof requirements is five years Therefore, if the house leaks within 5 years, you can ask the decoration company to take responsibility 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,
