Don't pay attention to these in winter coating construction? Is equivalent to doing nothing!

Winter cold, rainy, humid and other climatic characteristics appear, the temperature dropped significantly, when the internal and external wall paint project in the construction will encounter a lot of wall problems, internal and external wall paint engineering in the winter construction should pay attention to what?
winter construction conditions and requirements
For coating construction, qualified grass must be strong, flat, dry, neutral, clean five characteristics.
for coating construction, temperature is a more important factor, the construction environment temperature must be controlled above 5 degrees C, and the ambient humidity control within 85%, otherwise it is not possible to carry out construction.
Coating construction conditions requirements
for the construction of internal and external wall coatings, if the temperature is below 5 degrees C still need to carry out construction, in order to ensure the quality of construction, construction should pay attention to the following matters:
❶
budgest inspection
grass-roots inspection is the basis of the coating project, to remove dust, oil, loose matter on the grass-roots surface

;
❷
About putty construction
before entering the winter construction should ensure that the substrate drying and wall surface temperature, when the temperature is less than 5 degrees, as far as possible in the direct sunlight on the wall construction, the minimum temperature at night should be higher than 0 degrees C, otherwise can not be constructed.
❸
the putty is completely dry
putty must be completely dry before it can be polished, so that the putty is completely dry after polishing non-stick sandpaper and surface flatness control. If the putty is not dry or frozen, when polishing will appear putty sticky sandpaper phenomenon, the surface is not easy to polish flat.
❹
Coating construction
before coating to confirm that the substrate is completely dry, water-based paint construction temperature to be controlled at more than 5 degrees C, in the drying process when the temperature is below zero degrees when the emulsion will be frozen to lose bonding and film-forming function, to ensure that the minimum temperature in the film drying process can not be less than 0 degrees C.
❺
Coensing storage
into the winter paint construction, the site storage of paint should be placed in the indoor classification code, and ensure that the indoor temperature above 0 degrees C, the temperature below 0 degrees C must use heating or use electric heating to raise the indoor temperature, it is strictly prohibited to use open flame to raise the indoor temperature. Frozen products will not be available again.
❻Paint film maintenance and finished product protection
paint film on the surface of the object to achieve drying and optimal performance of the time, the standard temperature of 25 degrees C needs 7 days, for the winter paint construction environment temperature is generally low, paint film drying and the time to achieve the best performance to be relatively extended, during this period to minimize the paint film surface pollution, bump, to avoid pollution, bump caused by repair effect overall effect. Into the winter construction should be in accordance with the construction conditions of the site to do a good job of the corresponding protective measures to avoid film freezing, to ensure the quality of the project coating and the smooth progress of the construction.
