Common knowledge of coating: application of hydrophobic interior wall putty

Core tip: the most labor-intensive process in the interior wall coating project is the greasy grinding of the base layer, which is also the part with the highest construction cost In the normal construction, considering the material cost and labor efficiency, there is a certain problem in selecting putty In the process of making large surface leveling, the operation is mainly based on the scraping operation, which is basically not polished What's the problem of using putty with good strength and water resistance Title: the common dry powder putty made of white cement or lime calcium powder plus cooked rubber powder can be used, but when it is necessary to polish, the general painters will polish the putty immediately after the initial setting, otherwise it is difficult to polish it The experiment proves that the early 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: the most labor-intensive process in the interior wall coating project is the greasy grinding of the base layer, which is also the part with the highest construction cost In general construction, putty is selected in consideration of material cost and labor efficiency There are some problems In the process of making large surface leveling, the operation is mainly batch scraping, which is basically not polished There is no problem in using putty with good strength and water resistance The commonly used white cement is used Or the dry powder putty made of lime calcium powder and cooked rubber powder can be used But when it is necessary to polish, the painters will polish the putty immediately after the initial setting, otherwise it is difficult to polish it The experiment shows that the early polishing has a certain loss on the strength of the putty layer At this time, if the primer can be painted on it, it can enhance the base layer and isolate the alkaline base material However, primer is rarely used in general interior wall coating, and painters often choose materials with low strength but easy to polish, or even polish the putty with the surface layer easily polished by using cooked rubber powder and stone powder on their own site This kind of thing is common, so many walls appear wall coating after one or two years of use Peeling off phenomenon, the author has seen a lot of such phenomenon problems in this small amount of on-site preparation of polishing putty, using brush primer to strengthen the bottom layer can be solved, but the cost of painting has increased Another method is to select hydrophobic putty which is easy to polish The putty is completely water-resistant, and its burnability is equivalent to that of the polishing putty prepared with rubber powder The hydrophobic material of the material is made with acrylic emulsion, and the putty layer forms hydrophobic capillary effect, so as to achieve both water resistance and abrasion, and at the same time, isolate the basic alkaline material, improve the leveling of the film and reduce the amount of topcoat 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,
