The construction method of elastic drawing paint on the outer wall

Elastic lacquer is a face coating or medium coating with a pull-up effect for personalized decoration, which is widely used in the interior and exterior walls of buildings, as well as on substations such as lime and cement sand.
elastic pull paint has the following characteristics:
1) very artistic and three-dimensional sense;
2) good weather resistance, anti-mold resistance to alkali;
3) excellent elastic recovery and elasticity, can cover fine cracks;
4) extremely high strain and permanent toughness, to prevent cracking of the paint film.

base surface inspection
before construction, carefully check the base surface, batch layer need to be dried for at least 4 weeks, moisture content is less than 10%, PH value is less
than
10;
batch scraping putty
using high-quality putty on the construction surface batch scraping flat to flat degree meet the requirements, putty drying with the appropriate number of sandpaper sandpaper sanding flat, putty polishing, remove surface dust, water conservation 1-2 times.
spassing closed primer
brushing the exterior wall alkali-resistant closed primer 2 times, the paint consumption is about 0.125kg/m2, closed primer needs to be dry for 2-3 hours (standard conditions), in the elastic hair coating construction.
Roll applied elastic pull paint
choose a suitable aperture pineapple puller roller to take elastic pull paint, even roller on the applied base surface to apply the required pattern effect, make sure that the roller coating is uniform, carefully prevent leakage roller phenomenon, construction, prevent repeated roll coating in a person's place, otherwise easy to get involved in bubbles to form pinholes. Depending on the pattern size, the elastic brush unit consumption is approximately 0.75kg/m2.
Wash elastic paint
after the paint is completely dry, the use of wool roller paint elastic paint, elastic mask paint generally 2 times, unit consumption of about 0.23kg/m2.
the final coating effect, the overall color is uniform, the pattern is consistent.
notes are
1. Elastic drawing paint, before construction must be tried, determine the effect and then large-scale construction.
2. In order to prevent color inearable and obvious catchments, the walls within each split line shall be constructed once and shall be shut down at corners or slits of the walls.
. High temperature weather construction should avoid direct sunlight on the wall, extend the drying time of the paint film, avoid the appearance of catch-up.
. During construction, pay attention to local weather forecasts, and well-constructed elastic paint requires a drying time of 24h to prevent rework caused by rain-washed rings before drying out.
