Common knowledge of paint: causes of wood paint disease and preventive measures

It is suggested that there are many uneven ridge marks on the surface of the film, which affect the smoothness and brightness of the film （1） Reason: 1 The surface drying is fast and the film drying is uneven; 2 One time coating is too thick, only the surface is rapidly dry, the inside cannot be dry at the same time, the lower layer is loose and the upper layer is tight; 3 The lower coating is not completely dry, that is, the upper coating; 4、 The upper and lower coatings are not matched; 5 The primer is not completely dry, and the diluent of the top coat has too strong solubility, which makes the primer swell; 6 The addition amount of curing agent is too small; 7 The last coating is not fully polished, i.e the next coating Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: the surface of the film formed many uneven ridge marks, affecting the smooth and bright phenomenon of the film surface （1） Reasons: 1 The surface is dry fast, and the coating film is not even; 2 The coating is too thick at one time, only the surface is dry rapidly, the inner part cannot be dry at the same time, the lower layer is loose and the upper layer is tight; 3 The lower coating is not completely dry, that is, the upper layer is coated; 4 The upper and lower layers are not matched; 5 The primer is not completely dry, and the diluent dissolving force of the top coat is too strong, which makes the primer swelling; 6 The amount of curing agent added is too small; 7 The previous coating is not fully polished, i.e the next coating （2） Precautions 1 Use a slower drying diluent and a solvent with a proper solubility 2 Two or more times of coating, each time spraying time to allow the solvent to fully volatilize 3 Wait until the lower layer is dry enough, and then apply 4 Use the paint with the same properties to avoid the soft paint in the lower layer 5、 Avoid too thick coating, the bottom layer should be thoroughly dry before finishing 6 Properly increase the amount of curing agent 7 After drying, sanding should be as full 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,
