Common knowledge of coating: environmental requirements for floor coating construction

Core tip: floor construction environment requirements, usually floor coating construction environment requirements: relative humidity is less than 80%, the temperature needs to be in the range of 10 to 35 ℃ Beyond this range, special floor coating varieties are required During the coating and curing process (before surface drying) of floor coating (especially finishing coat), the surface temperature of the base material shall be higher than the dew point by more than 3 ℃, so as to prevent the condensation of water vapor on the surface of the base material and wet film from affecting the adhesion and surface effect of the coating It is better to construct in the morning or evening in summer The temperature shall be measured during construction When the temperature exceeds 35 ℃, for the health of construction personnel and high quality coating quality Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: floor construction environment requirements, usually floor coating construction environment requirements: relative humidity is less than 80%, temperature needs to be in the range of 10 to 35 degrees Celsius Beyond this range, special floor coating varieties are required During the coating and curing process (before surface drying) of floor coating (especially finishing coat), the surface temperature of the base material shall be higher than the dew point by more than 3 ℃, so as to prevent the condensation of water vapor on the surface of the base material and wet film from affecting the adhesion and surface effect of the coating It is better to construct in the morning or evening in summer The temperature shall be measured during construction When the temperature exceeds 35 ℃, the construction shall be avoided for the health of the construction personnel and the quality of high-quality coating During the construction in wet and rainy days, it is necessary to measure the relative humidity and dew point temperature, check the quality of the dried film at any time, and repair it in time in case of cracks, orange peel, peeling off and other phenomena For two-component coatings, slow volatilizing solvent should be used as much as possible when preparing diluent and curing agent When mixing component A and component B, the principle of small amount and multiple times of frequent matching should be used to prevent the phenomenon of exothermic too fast during the curing of the coating from causing the coating to be scrapped When the temperature is too high, the two-component coating, especially the non soluble two-component coating, is prone to explosive polymerization, that is, the coating reaction is too fast, a large number of exothermic, which shortens the service life of the coating In the process of construction under high temperature, although the drying rate of the coating will be faster, the next coating shall be carried out according to a certain coating interval even if it has been determined to be dry 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,
