It is the change of season in autumn and winter. The weather turns cool. Along with the weather changes, exterior wall coating engineering in construction may meet all kinds of problems, to solve the exterior wall engineering in winter construction, water paint brand small make up, with the following instructions and Suggestions for the construction of reference:

    1. Winter construction conditions and requirements

For coating construction, the qualified base has five basic characteristics: strong, smooth, dry, neutral and clean. While construction environment: the environment temperature must be controlled in 5 ℃ above, environmental humidity control within 85%, otherwise you can't construction.

    2. Coating construction conditions and requirements

    In view of the construction of exterior wall coating, part of the project due to the time limit for a project requirements after entering the winter when the temperature is below 5 ℃ still need to undertake the construction, in order to guarantee the construction quality, construction period must pay attention the following matters:

    The basic treatment is the foundation of the coating project. The basic treatment includes: removing dust, oil and loose matter from the surface of the base layer; Alleviating or eliminating surface defects; Improve physical or chemical properties of base surfaces. Winter construction when the temperature of the substrate humidity is too low, cement substrate part with white phenomenon, at the bottom of the drying is not easy to determine, generally the mortar new substrate, maintenance period for more than 14 days in winter.

    3, the gap repair is not good

    In addition, in a few metope and door, the place that window is opposite, as well as the place that two kinds of different color coating butt in, also be the place that worker often perfunctory finish. You will often see latex paint and wood paint mixed with each other between the joint problems.

    Countermeasures: it is very important to deal with the joints. You must supervise the workers' careful construction. If there are two kinds of color coating on metope relative, it must be in the construction in the first color paste in the edge of the tape, on the besmear again another color coating, such as long as you go after the completion of the construction to tear tape, the joints can very neat.

    Waterproof acceptance inspection:

    1. The correct waterproof acceptance is that the inspection and acceptance project can be carried out 24 hours after the completion of the waterproof project.

    2, specific acceptance step is: water experiments, reservoir depth in more than 30 mm, time is more than 24 hours, observe whether the water level is reduced, the next day if it is found that the size is big, it is said the waterproof do not qualified, should be twice done.
