| Summer special attention wall painting lacquer |
Entered in August, at this time because of the climate characteristics and a longer duration of bright sunshine, can make better exterior lacquer film forming, the construction time can be appropriately extended, so as to shorten the construction period, and is the best opportunity for lacquer construction. At the same time, we the site engineering of lacquer construction was in full swing, but also did not forget to interested friends share "summer lacquer and metope coating construction, special attention to matters" dry knowledge of energy!
Impact one: high temperature weather
Dry coating, conjunctival needs under certain temperature and humidity, different types of coatings have the best film - forming conditions, usually solvent type coating should be construction in the 5-30 DEG C temperature conditions, water emulsion coatings should be construction in 10-35 DEG C temperature conditions. The summer heat of the weather will make the paint dry quickly, and make the durability of the coating is affected.
Impact two: dry weather
Although it is rainy in summer, it is also a lot of hot dry weather. And suitable coating construction temperature of 60-70, usually cases, low humidity to paint film and improve the construction progress, but if the humidity is too low, the air is too dry, solvent based paint solvent too fast, emulsion coating drying too fast will conjunctival completely inadequate, and therefore should not be in construction.
Impact three: Sunshine weather
In the summer, the sun is strong, the basic surface temperature is too high, will cause water or solvent evaporation too fast and film coating, affecting the quality of the coating.
Impact four: multi wind weather
Summer many and big wind, the wind will accelerate the evaporation of the solvent or water, poor membrane, and dust contamination, and paint the comfortable degree compared, sunny weather conditions on the coating engineering is more important, poor coating conditions will make coating engineering to sell at a discount greatly.
The above 4 points for the influence of different weather to paint the walls in summer, Jia Jia think as long as the weather is not extreme, to take the appropriate construction method, can do metope besmear brushs the job. Jasper stone painting after many years of practice experience Lizhen, provide solutions as follows:
1 pay attention to keep good paint
The summer season to paint stored in a cool ventilated place, and storage containers must be sealed. Stone: usually buy paint consumed within two months
2 extended wall putty dry time
The first batch of scraping putty before painting the wall, generally require scraping 1-3 times, during the normal dry time for 1-2 days. Because the weather is hot and humid in summer and autumn, especially when the rain comes, the drying time will be extended.
The proposed renovation in the summer season, as far as possible to extend the putty dry time, generally 2-3 day
3 wall brush to avoid rainy days
Summer and autumn paint, should be avoided in humid or rainy weather. Construction, the wall foundation is wet, not completely dry painted coating, water penetrate paint causing Qimo lost adhesion and lead to the drum wall bulge. |
