Range of polyurethane waterproof coating process is suitable for a variety of construction projects with a protective layer of roofing, bathroom, underground construction waterproofing works. Construction preparation 1. Body Material: Part A (pre-mer) and Part B (cured body) 2. Construction tools: Name Application Name Application electric mixer mixing A and B material with a paint brush primer mixed with spices bucket A , B material with rolling brush primer paint bucket fitted with a small trowel mix with a small grass patch with a plastic scraper scraping mix oil workers clean up grass blade scraper with a metal small parts in a complex mixture Scraping mop Cleanup grassroots scraping with a rubber scraper mix the ingredients with the weighing scales 50kg primary surface treatment process polyurethane primer coating → → → scraping locally enhanced polyurethane coating one, two, three times → surface protection or modified grassroots requirements and processing 1. Waterproof grassroots design requirements should be wiped with cement mortar 1:3 1/50 slope into the pan of water on its surface to smooth pressure light, not allowed to have uneven, loose sand away from the ash and other defects exist. Drain or floor drain site should be less than the whole waterproof layer, so as to exclude water. Cased piping parts should be more than 20mm above the grass surface. Kok Yin and Yang should be made part of a small fillet radius 10mm for coating. 2. All fittings, sanitary equipment, floor drain or drains, etc. must be securely installed, joints tight, close the first smooth, without any loosening. 3. construction, when construction of traditional polyurethane waterproof coating, waterproof substrate should be substantially dry state, less than 9% moisture content is appropriate, its simple measurement method is an area of ??1 square meters and a thickness of 1.5 ~ 2.0mm rubber plate covers grass surface, place 2 to 3 hours, such as covering the primary surface no watermark, close to the grass roots side of the rubber sheet nor condensation watermark, based on experience explain the water rate less than 9%, in line with the construction requirements. 4. Before construction, shovel and broom prior to the projection surface of the substrate, mortar and other foreign matter eradicate pimple, dust and debris and thoroughly cleaned. On the angle, pipe roots, floor drain and gutter mouth and other parts should carefully clean, if there is oil, rust, etc., use wire brushes, sandpaper and organic solvents which thoroughly cleaned. Construction Requirements 1. coating primer: This step corresponds to the conventional construction bitumen cold brushing base oil, which aims to cut grass moisture loss from the drum to prevent the waterproof coating; strengthening the grassroots level, to improve the adhesive strength of the coating and base to prevent the emergence needle coating porosity and other defects. I recommend using a polyurethane primer as a primary treatment. The preparation of a polyurethane primer: A polyurethane material, B material according to the proportion of 1: 2 to 3 (weight ratio) with (other coating with a predetermined ratio according to product specifications). When the B material relatively thick, available dedicated diluent, must not use acid or oil of diluent containing product quality so as not to affect the original. In the preparation, the dilution should first B material was stirred for 2-3 minutes, if no dilution, can be directly used B group assignments and stirred for 5-10 minutes, the stirrer raised, can be seen even better liquid slowly slip from the container also it should be noted that the material should immediately open reclosable avoid solidification scrap, the mixture should be based on the actual amount, which is equipped ready to use. (Note: 991 type of construction material into the mix when the methyl ethyl compound were stirred with 911, 851 and vice versa) 2. Local Enhancement: for expansion joints, control joints, angle, pipe joints, etc., by a layer reinforced cloth reinforced, waterproof overall cure before construction. 3. Construction of the first pass coating: After the primer substantially dry curing requirements with plastic or rubber scraper evenly coated layer of paint scraping, scraping uniform, not too thick or too thin, scraping thickness is 0.8 mm or so. Scraping the beginning, it should be based on construction size, shape and materials, unity considering construction retreat and scraping order. The second time-coat application: After the first pass coating substantially cured, and then a second time on its surface scratch coating, scraping method with the first pass coating. To ensure water quality, scraping the direction must be perpendicular to the scraping direction of the first layer. Recoat time, the degree of construction when the temperature and the coating cured (not sticky to hand touch) to determine. 5. After the second time cure the coating, then the method described above for the third time scraping film. 6. Paving protective layer or facing material: the third time construction is completed and the film is not completely cured, it can be sprinkled with a small amount of clean sand on its surface dilute (diameter of not more than 2mm), in order to increase the coating layer will be bonding capacity between covering cement mortar. When the film was cured completely and check acceptance, you can wipe the protective layer of cement mortar or paste tile, mosaic floor finishes. 7. Construction craft two three painted cloth: This process currently on the market is not much use, method of operation of this process is: In accordance with the above description of the process is the same grass-roots, finished the first pass after brushing, will Plaid uniform paving glass screen at the top, by a polyurethane adhesive force to cement, after drying the first pass in the same way a second time, until all dry, and finally in accordance with the above requirements brushing polyurethane waterproof paint. Bathroom, kitchen and roof construction methods consistent. Note that when the glass screen grid paving should be smooth, because of the relatively small space of the bathroom, making mesh paving should be pre-treated. Other requirements with polyurethane construction technology requirements consistent tradition. 1. When the coating viscosity is too large, inconvenient construction were scratch, add a small amount of thinner diluted to reduce the viscosity, an amount not greater than 10% of B material. (Note: For diluted polyurethane user must use the companies supporting the market if the purchase xylene thinner, gasoline and other diluents, caused by quality problems, the company is not responsible.) 2. pores, bubbles: materials, mixing way and mixing time is not uniform mixing of the material; construction should use the power, but the high speed blender. Another reason is the primary treatment unclean, before doing the film should carefully clean grass, not a floating sand and dust, on a more basic level should craft should have pores pores, coating layers required to deal appears to prevent coating damage resulting in leakage. 3. play drums: the grassroots from the skin, sand, cracking, drying, the adhesive film is bad; grassroots construction should be carefully operation, maintenance, to be dried grass, first coated with a primer, after curing, and then waterproof layer brushing construction craft drill. The film Alice: Edge waterproof layer, sub-brush lap, peeling Alice appeared with grass-roots phenomenon. The main reason is unclean or not dried grass, close the first operation is not careful, the seal is not good, not strong underlying paint adhesion caused Alice. Therefore, to ensure that the grass-roots clean, dry, be careful operation. 5. damaged: waterproof coating layer coating layered construction process all construction completed or not and so cure the coating on the Master operating activities, or placing tools and materials, will damage the film. Scratches. Construction should be complete protection coating. 6. The construction should pay attention to fire prevention, construction should take protective measures, the construction site requires a well-ventilated to prevent solvent poisoning. 7. The quantity found in precipitation phenomenon, should stir before use, so as not to affect the quality of 8. A and B of the two materials are metal pail, flammable, toxic, storage should be sealed and placed in a cool, dry, strong direct sunlight venues. 9. Construction temperature should be above 5 ℃.
