Coating technology: how to construct interior wall environmental protection coating

Core tips: 1 Base treatment: 1.1 carefully check whether there is hollowing on the wall, wall attached pull joint and steel head and steel pipe left on the wall are marked with chalk 1.2 check whether there are interface cracks, settlement cracks, crazing and structural cracks on the wall, and mark them with chalk 1.3 whether the strength and flatness of the mortar layer meet the requirements of the contract 1.4 whether there are oil, wax, rubber, soluble hydrochloric acid substances and falling off easily on the construction surface Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: 1 Base treatment: 1.1 carefully check whether there is hollowing on the wall, wall attached pull joint and the steel head and steel pipe left on the wall are marked with chalk 1.2 check whether there are interface cracks, settlement cracks, crazing and structural cracks on the wall, and mark them with chalk 1.3 whether the strength and flatness of the mortar layer meet the requirements of the contract 1.4 whether there are oil, wax, rubber, soluble hydrochloric acid substances, falling off and putrefaction on the construction surface 1.5 the moisture content, salinity and alkalinity of the base course meet the requirements Note: the owner shall be contacted in written form for all site problems Any unqualified base surface shall be rectified immediately 1.5 clean the base surface, and remove the floating ash, cement and other attachments on the construction surface with a blade and a brown brush 1.6 fill the hole with crayford No.1 putty, and polish the convex part of its surface to meet the flatness requirement (≤ 2 mm) after it is dried 1.7 use a grinder or 100 mesh sandpaper to sand the obvious raised surface, and grind the raised part to meet the flatness requirements (< 2mm) 1.8 construction requirements: 1.8.1 the base course shall be free of floating ash and other attachments 1.8.2 the flatness shall meet the requirements (≤ 2mm) Two, the first time putty layer construction: 2.1 construction ratio: according to the purchased finished putty ratio requirements, the allocated putty can be placed for 4 hours at most, can not be used for more than 4 hours, and can not be used for the solidified slurry 2.2 the finished putty available for purchase in this layer is as follows: during the construction of 2.3 of crayford No.1 putty, it shall be spot patched in advance, and after it is dry, the surface shall be sanded to remove the rough surface, and then the first full batch of work shall be carried out 2.4 sanding: the putty layer can be sanded after the first time it turns white If there are obvious knife marks and rough putty surface, it shall be removed or sanded Sanding shall be completed before maintenance If the putty layer is completely solidified before sanding, the labor cost and sandpaper cost will increase significantly 2.5 maintenance: after the construction of the first putty layer, the maintenance time shall be at least 8 hours apart before entering the next construction procedure, so that the putty layer can be fully cured 2.6 construction requirements: 2.6.1 the flatness meets the requirements (≤ 1.5mm) 2.6.2 the putty layer shall be smooth without obvious marks 2.6.3 the adhesive force is qualified, and the nail is used to pick up without powder dropping 3、 The second putty layer construction: 3.1 selected product: Kraft 1 putty 3.2 construction method: one thin batch 3.3 drying time: at least 4 hours (sunny) 3.4 sanding: use 320 mesh sandpaper for sanding, and wipe off the dust with a rag after sanding 3.5 construction requirements: 3.5.1 the surface shall be smooth without obvious batch scratch marks 3.5.2 no floating dust 3.5.3 the flatness shall meet the requirements (≤ 1.0mm) IV primer construction (coreford special interior wall primer) (if the wall is renovated, the special treatment of the base course shall be carried out immediately after the completion of this process) 4.1 construction ratio: (texture effect) direct construction without dilution; (flat coating effect) water dilution according to the technical ratio 4.2 construction tools: roller, brush, spray gun 4.3 construction times: once 4.4 completion time: 6 hours 4.5 construction requirements: 4.5.1 the construction shall be uniform without missing coating 4.5.2 the construction material consumption shall be achieved Coating rate: special primer for interior wall (10% - 20% diluted with water) 10-12 m2 / kg; note: the above is the theoretical coating rate, and the actual consumption will vary with the site construction conditions and painting methods 5、 Construction proportion of medium coating: generally, no dilution is required, and appropriate amount of clean water can be added to dilute if necessary 5.2 construction tools: texture, texture, Edith - medium wool roller (you can search for more information about the use of tools) liangbai, Lixin, Jialian - short hair roller, brush 5.3 drying time: conventional products can be dried for 6 hours for the next construction; texture decoration can be dried for one day (sunny) before the next construction 5.4 sanding: use 320 mesh sandpaper for sanding, sanding to remove the rough surface on the wall, and use a rag to remove the dust 5.5 construction requirements 5.5.1 the color shall be uniform without missing coating 5.5.2 the surface is smooth and tidy, with uniform covering power and no blooming Coating rate: liangbai, Lixin, Jialian - (flat coating effect and water dilution 15%) 10-12m2 / kg; texture, Edith - (texture effect and water dilution 10%) 10m2 / kg; texture - (texture effect and water dilution 15%) 7-8m2 / kg; note: the above is the theoretical coating rate, and the actual consumption will change with the site construction conditions and painting methods 6、 Surface coating construction: 6.1 construction ratio: generally, no dilution is required, and appropriate amount of clean water can be added for dilution if necessary 6.2 construction tools: texture - honeycomb drum Texture, Edith - Medium hair roller Liangbai, Lixin, Jialian - short hair roller, brush 6.3 the construction effect shall be in accordance with the sample requirements 6.4 construction requirements: 6.4.1 the effect shall meet the sample requirements 6.4.2 the rolling coating shall be uniform without blooming 6.4.3 no bottom leakage Coating rate: liangbai, Lixin, Jialian - (the flat coating effect is diluted with 10% water) 10-12m2 / kg; texture, Edith - 10m2 / kg; texture - 3-4m2 / kg; (the water proportion is not more than 5%); note: the above is the theoretical coating rate, and the actual consumption will change with the site construction conditions and painting methods 7、 Precautions: 7.1 when the temperature is lower than 5 ℃ and the relative humidity is higher than 85%, it is not suitable for construction; 7.2 within 12 hours after the completion of construction, pay attention to waterproof and external force damage; 7.3 if it is accidentally splashed into the eyes, immediately wash it with water or go to the hospital for treatment; 7.4 if the paint splashes on the skin, wipe it off first and then wash it with soap water; 7.5 Please store it in a cool and dry place It can be stored for 24 months without opening the tank Products that have been opened can not be stored for a long time, so they should be used as soon as possible 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,
