Common sense of coating: Waterproof selection and construction question and answer of coating strategy

Core tip: for the decoration of new houses, it is necessary to carry out water and electricity transformation Slotting and burying pipes will inevitably destroy the waterproof layer made by the original developer In order to strengthen the waterproof setting, protect property safety and avoid neighborhood disputes, second, if the waterproof is made up again, the cost is about 5-10 times of that before the decoration So the new house decoration must be waterproof What are the main parts of waterproof home decoration? The floor and wall of toilet and bath room, the floor and wall of kitchen and balcony, all floors and walls of first floor residence, the floor and all walls of basement shall be treated with waterproof and moisture-proof treatment How to calculate the waterproof area in home decoration?

The floor and wall of toilet and bath room, the floor and wall of kitchen and balcony, all floors and walls of first floor residence, the floor and all walls of basement shall be treated with waterproof and moisture-proof treatment How to calculate the waterproof area in home decoration? Waterproof area of toilet and bath (M2) = (perimeter of toilet and bath floor width of door) x 1.8m (height) + (floor area) waterproof area of kitchen (M2) = (perimeter of kitchen floor width of door) x 0.3m (height) + (floor area) waterproof area of balcony (M2) = (perimeter of balcony floor width of door) x 1.8m (height) + (floor area) how to judge the quality of waterproof materials? The judgment of waterproof materials mainly considers four aspects: ① the coating should be free of precipitation, stratification and agglomeration; ② there is no strong smell; ③ the construction is convenient; ④ whether it is a large brand product, why should the waterproof between toilets and bathrooms be 1.8m high? This mainly considers the safety and overall waterproof effect of toilet and bath Generally, the sprinkler or nozzle is installed at about 1.8m high If the waterproofing is low, the long-term spray will cause water to soak the wall, mildew the wall, peeling off the wall decorative coating or face brick, etc In principle, the non shower wall should be 1.5m high, but in order to strengthen the waterproof function, we will achieve a unified height of 1.8m, and the cost will not increase much In addition, for the light body wall or self built light body wall reconstructed in the toilet and bath room, it is suggested that the waterproof height should be at the top In the process of decoration, when to start waterproof? Home decoration, water and electricity transformation first, after the completion of water and electricity transformation, waterproof should be done immediately It should be noted that the waterproofing should be placed on the structural base as far as possible How to judge whether the waterproofing is done well? Mainly through closed water test Visual inspection method: open the bathroom downstairs to observe whether there is any trace or water drop on the ceiling Contact inspection method: touch the suspected water seepage place by hand to confirm whether there is water leakage What are the most critical steps in construction? The most critical step in the construction is the base course surface treatment and later protection If the base surface is not well treated, for example, building a castle in the air, how to do it is also empty talk; if we do not protect it in the later stage, brushing it is also equivalent to pasting a net with eyes, which can not play a waterproof role How to do the later protection well? The function of the protective layer is to protect the waterproof layer from damage during the later construction After the completion of home waterproof construction (24 hours after the completion of closed water test), the solidified waterproof layer also needs to be protected It is strictly forbidden to step on, pile up or drill holes You can lay some cartons on the waterproof layer and then do other processes Where are plugging products used? What is its function? Can it be used as waterproof material? Plugging products are defined as rigid waterproofing There are two types of plugging products: quick setting type and slow setting type Quick setting type is generally used for the repair of kitchen and toilet The second slow setting type can be used as rigid waterproof material, but because it has no elasticity, poor adhesion, easy to crack and form leakage It is not recommended to be used as main waterproof layer, especially in the climate with large temperature difference in winter and great changes in dry and wet conditions What are the main considerations for choosing waterproof materials? The first is waterproof performance, and then environmental protection performance Waterproofing is a concealed project After waterproofing, it is pasted and installed If toxic materials are selected, it is like burying a "poison bomb" at home, releasing the poison gas for a long time, and it is difficult to dismantle and replace it again, so the environmental protection of materials is also an important aspect of selecting materials What are the specific waterproof requirements for each part of the house? The floors and walls of all the rooms in the bathroom, kitchen, balcony, basement and the first floor shall be provided with waterproof layer The water pipe groove in the cavity shall also be waterproof When the pipeline and floor drain pass through the floor slab, the waterproof layer around the hole must be constructed carefully For the embedded water pipe in the wall, the groove larger than the pipe diameter shall be removed, and the plastering in the groove shall be smooth, and the waterproof coating shall be applied What key links should be supervised during the construction of waterproof layer? It mainly includes the following points: ① the waterproof part shall be comprehensive; ② the waterproof layer shall be painted in strict accordance with the product specification and reach a certain thickness; ③ the construction process shall be meticulous, and the joints between the wall and the ground, internal and external corners, water pipes, floor drains and sanitary wares The surrounding area and the anchor ditch for laying the cold and hot pipes are the key waterproof parts, which must be careful during construction (non-woven mesh cloth is added) What principle should be followed and what standard should be reached when applying the waterproof layer by scraping? The principle of scraping and coating the waterproof layer shall be based on the details (pipe root, water leakage hole, etc.) first and then the large surface (wall and ground) The internal and external corners shall be made into a circular arc shape Before the construction of a large area of waterproof, according to the design requirements, the grooves shall be filled with sealing materials, and the joints of gutter, eaves gutter, internal and external corners, pipe root, etc shall be painted twice with a brush The waterproof coating shall be fully applied without omission and firmly bonded with the base course There is no bubble, crack, delamination and flat surface The coating height of the rolled up part is basically uniform, and the thickness shall meet the specified requirements of the product The construction of waterproof coating shall be carried out step by step according to the time schedule specified in the specification, and other subsequent works shall be carried out after the construction link is completed 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,
