Common knowledge of coating: reason why floor coating is not suitable for winter construction and Countermeasures

Core tip: with the arrival of winter, the weather is getting colder and colder, more and more attention should be paid to floor paint coating Therefore, many floor construction teams suspend the floor construction in winter The reason why the floor paint can't be applied in winter and the countermeasures are analyzed First of all, we must make clear the best conditions of floor paint construction The best construction conditions of floor paint put forward requirements for both temperature and humidity: the relative humidity of air is less than 75%, the temperature is controlled at 10-35 ℃, the surface temperature of the painted object during the construction of floor paint should be higher than the dew point by more than 3 ° C, and the temperature should not be low Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: with the arrival of winter, the weather is getting colder and colder, more and more attention should be paid to floor paint coating Therefore, many floor construction teams suspend the construction of floor works in winter The reason why the floor paint can't be applied in winter and the countermeasures are analyzed First of all, we must make clear the best conditions of floor paint construction The best construction conditions of floor paint put forward requirements for both temperature and humidity: the relative humidity of air is less than 75%, the temperature is controlled at 10-35 degrees, the surface temperature of the painted object during the construction of floor paint shall be higher than the dew point by more than 3 ° C, and the temperature shall not be lower than the minimum temperature (5 degrees centigrade) specified by the paint drying Therefore, if the corresponding measures are not taken, there will be the following disadvantages in the winter floor paint Construction: first, slow down the paint reaction When the ambient temperature is lower than 5 ℃, the reaction of the floor coating will be reduced or slowed down, which will seriously affect the curing performance of the floor coating, and then lead to long surface drying time of the coating, which will increase the possibility of coating pollution 2、 Viscosity multiplied At low temperature, the viscosity of floor coating increases exponentially and the leveling property decreases If the leveling performance becomes poor, the trowel mark is easy to appear 3、 Reduce the coating quality As the curing reaction slows down, or the completion can not be cured, the strength, hardness and wear resistance of the coating will be reduced, and the floor separation and other problems will occur, affecting the service life So, if the floor paint construction project really needs to be constructed in winter or low temperature environment, what are the countermeasures? 1、 Avoid the low temperature period for construction During the construction of epoxy floor coating, try to avoid the low temperature period It is recommended to start construction after 10 a.m and stop construction at 3 p.m 2、 Warming: on the one hand, it can increase the room temperature Open the heating before construction, and raise the indoor temperature to more than 5 ℃ for construction On the other hand, the coating can be heated Place the paint in a warm environment or heat it with steam or hot water Pay attention to prevent water infiltration and control the heating temperature below 38 ℃ 3、 Add solvent to the paint It can add less than 5% solvents with faster volatilization rate, such as acetone, ethyl acetate, etc Solve the problem of high viscosity and lack of leveling of floor paint at low temperature It can be seen that everything is not absolute, as long as the corresponding measures are taken, the winter floor paint can also be constructed 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,
