How to construct colorful imitation stone paint on old walls.

The old wall surface is generally cement surface, paint surface, water brush stone surface, brick wall, etc. , the main difficulty and key point in the construction lies in the grass-roots treatment, the grass-roots treatment of good or bad directly affect the construction effect and decorative effect of colorful imitation stone coating. In the actual construction according to different substrate design different treatment programs and construction procedures, the main construction steps are:
▍
bottom treatment:
first of all on the smooth old tiles rolled tile surface renovation interface agent, can quickly immerse into the tile, and in the tile appearance to form a high and low rough interface with a certain resistance, improve putty and other coating layer and bottom layer bonding strength. (Before rolling tile surface refurbishment interface agent, wash with high-pressure water, finishing the surface of the tile floating ash and oil, empty drum, de-layering and other damaged parts of the partial removal, the use of cement mortar to repair flat)
. ▍
putty to find flat:
in the rough interface agent coating after coarse scraping the outer wall special putty to find

. Here to remind is that we must use the external wall special putty, outdoor environment such as wind and sun, rain wash, high temperature baking, low temperature freezing and melting, the wall decoration layer water resistance, crack resistance, alkali anti-mold resistance, weather resistance, etc. than indoor decoration putty requirements are much higher.
▍
closed primer:
To enhance the adhesion of the coating film, the old wall construction must be painted closed primer, to be closed primer completely dry before the multicolored imitation stone paint spraying work.
▍
spray multicolored imitation stone paint:
spray multicolored paint coloring, drying with a special spray gun evenly sprayed multicolored imitation stone paint 1-2 times, each construction interval of 12 hours (23±2 degrees C), after the spray drying 24 hours, with spray gun uniform spray hood varnish 1-2 times, each interval of 4-6 hours.
don't forget that when the primer is finished, splitting the walls improves the results. Referring to the external wall dry hanging stone style, in the eaves and window area should be divided, the grid line should be turned to the inside of the window frame;
five characteristics of colorful imitation stone paint will make you fascinated by her!
1, high degree of simulation stone
products using the package and dispersion suspension technology, so that different colors of the same liquid mixed together, still can maintain relative independence, in which a wealth of color points naturally imitate the texture effect of granite, is a very cost-effective imitation stone coating.
2, simple construction
compared with the traditional multi-layer process, the construction time can be effectively shortened by more than 20%, and the quality effect is far better than the traditional process effect.
3, long-lasting weather resistance
using a fluorosilicon resin system, so that multicolored imitation stone coatings have a strong chemical stability, and thus has excellent UV resistance and long-lasting weather resistance.
4, anti-cracking
using a combination of elastic coating system, the system coating has the ability to cover the crack of the wall, to ensure waterproofing and prevent cracking of the wall.
5, super self-cleaning
air all kinds of dirt is not easy to accumulate, attached to the surface of dust is also easy to be washed away by rain, very strong resistance to pollution, to maintain long-term cleanliness.
