I can't afford to hurt, I really can't afford it! It's obvious that I have to rely on my talents to eat, but I'm all fighting for the value. This is not the case. The façade of the façade that was raised in the 1990s has been erected in the baptism of the years. In order to be able to take a look at the self-built housing group, you have to change the popular new outerwear - exterior paint.
Once, lack of choice, most of the exterior wall decoration can only choose to affix wall tiles. Nowadays, it is different. The exterior stone paint, imitation stone paint, colorful paint, rock lacquer, liquid granite and other paints are chosen by you, and the cultural stone is matched with more effects.
Renovation of the tiling exterior wall of the self-built house into the exterior wall of the brush coating requires strict refurbishment processes and processes:
1. Grassroots processing. In the past, the first step in the renovation of old tile walls was to ask the special brick-blasting team to knock out and remove the old tiles first, which was time-consuming and labor-intensive. Now there is a tile surface renovation interface agent, which greatly improves the efficiency of the base layer treatment. It can be directly coated on the smooth old tile, which can quickly penetrate into the tile and form a rough interface with certain toughness on the surface of the tile to improve the finish layer of the putty and the like. Bond strength at the base level. (PS: Before rolling the tile surface to renovate the interface agent, rinse with high-pressure water, clean the surface of the tile surface and oil stains; partially remove the damaged parts such as empty drums and delamination, and repair with cement mortar)
2, putty leveling. The outer wall special putty is scraped on the coarsened interface coating after roughening for leveling. It should be reminded that it is necessary to use special putty for exterior wall, outdoor environment such as wind and sun, rain washing, high temperature baking, low temperature freezing and thawing, water resistance, crack resistance, alkali resistance and mildew resistance to the wall decorative layer. Sex, weather resistance, etc. are much higher than the interior decoration putty requirements.
The outer wall putty is generally 2-3 times to survive, and the thickness of each batch of scraping should not be too thick, avoiding the cracking of the putty layer caused by the large shrinkage strength. If the special putty for the exterior wall of the masons is used, the thickness of the scraping of each pass should not exceed 1.5 mm, and the total scraping thickness of the putty layer should not exceed 3 mm. The scraping time of the front and back putty should not be too long. The next putty should be scraped after the front putty is dry. After the putty layer is dry, it should be polished in time.
3. Apply a permeation-blocking primer. The closed primer can seal the alkalinity of the wall surface, adjust the permeability of the bottom layer, and increase the adhesion of the exterior wall paint coating, so it can not save the trouble and not brush or brush.
4, the exterior wall paint. The choice of exterior wall paint can be determined according to the desired effect, whether it is real stone paint, stone paint, or liquid granite. For the choice of color, it is recommended to coordinate with the surrounding environment, coordinate with the selected cultural stone, etc.; avoid too bright, because the color of the bright exterior paint color is a test for the big brands, easy to fade; also need to consider the local Custom or feng shui issues.
Finally, for the renovation of the external wall, pay special attention to the weather forecast to avoid working before the rain and snow. Good time and good people and talents can be used to replace the old tiles and self-built houses with beautiful paints and new clothes.
