A collection of common construction problems and solutions for putty

China Paint Online News Information:
, why putty pulp after 5 minutes to sit still?1, because putty contains a certain proportion of polymer polymers and other dry powder-like additives, these materials to fully absorb water dissolved, in order to play its role, to achieve the best results.2, due to the fine powder particles, need a certain amount of water absorption time.3, eliminate the production of bubbles., putty strength is not enough, powder (drop powder)reason:1, water is not appropriate.2, too much round-trip scraping.3, the water absorption rate of the substation is too large.4, the weather is hot or dry.5, putty stirring unevenly.solution:1, when pulping according to the proportion of the instruction manual.2, master the construction method, to minimize repeated scraping.3, before the construction of the base surface wet, after construction for maintenance.4, before the construction of the substation wet, after the construction of maintenance.5, stir the putty well. , putty construction process, the slurry quickly dry reasons: 1, the slurry stirring is not uniform, the slurry stirring did not sit. 2, the initial addition of too much water, and then add powder seasoning, powder can not fully absorb water. 3, the base water absorption rate is very high or the weather is hot and dry. Solution: 1, when stirring the application of electric mixer stirring well, while paying attention to the bottom of the barrel and corner position of the powder to be fully stirred, until evenly no granulation, and then set aside for 5 minutes slightly stirring can be used. 2, the initial stage of pulp do not add too much water, if the slurry is too thick, can be appropriately added to the water, should try to use water to adjust the thinness of the slurry. 3, wetting the substing before construction. , putty batch scraping after there are pores or bubbles appear 1, stirring when the slurry gas into the slurry. 2, powder delicate, easy to produce bubbles. 3, the substation is drier or the absorption rate is larger. 4, twice the construction interval is not enough, that is, after the previous construction, no table dry, the second construction. solution: 1, the powder should be stirred after 5 minutes of silence. 2, when the substation is dry, should be wet in advance. 3, the previous layer of construction table dry (about 2 to 4 hours), in order to carry out the next layer of construction. 4, putty batch scraping, with the batch knife anti-pressure pores can be removed. , putty layer cracks main reasons: 1, large substation deformation or grass-roots cracking. 2, the base surface cleaning is not clean. 3, a batch scrape is too thick. 4, the weather is hot or dry, the base temperature is too high, the putty layer is drying too fast. 5, putty scrapes over thickness at a time solution: 1, make the substring stable or repair cracks in advance. 2, clean up the grass roots. 3, each layer of batch scraping should not be too thick. 4, before the construction of the appropriate substing wet, reduce the base surface temperature. 5, each time putty construction thickness of 0.5 to 1mm total thickness is not less than 1mm.
