A new house was built in my old home. Should the exterior walls be made of ceramic tiles or imitation stone paint?

In the past, there was a lack of choices and most of the only choices for exterior wall decoration were wall tiles. Nowadays, things are different. You can choose exterior wall real stone paint, imitation stone paint, colorful paint, rock chip paint, liquid granite and other coatings, and match them with cultural stones to achieve more effects.

Renovating the tiled exterior walls of a self-built house into painted exterior walls requires strict renovation techniques and procedures

1. Base layer treatment.

In the past, the first step in renovating old ceramic tile walls was to hire a dedicated brick demolition team to knock out and remove all the old ceramic tiles, which was time-consuming, labor-intensive and labor-intensive. Nowadays, there is an interface agent for tile surface renovation, which greatly improves the efficiency of base treatment. It can be directly rolled on smooth old tiles, which can quickly penetrate into the tiles and form a rough and uneven interface with a certain toughness on the surface of the tiles, improving the interaction between putty and other finishing layers. Base layer bonding strength. (PS: Before rolling the interface agent for ceramic tile surface renovation, use high-pressure water to rinse and clean the floating dust and oil on the ceramic tile surface; partially remove damaged areas such as hollows and delamination, and use cement mortar to repair and smooth them)

2. Putty leveling

Scrape the special putty for exterior walls on the roughened rough interface agent coating for leveling. What should be reminded here is that special putty must be used for exterior walls. Outdoor environments such as wind and sun, rain erosion, high temperature baking, low temperature freezing and thawing, have good water resistance, crack resistance, alkali resistance and mildew resistance for the wall decorative layer. The requirements for durability and weather resistance are much higher than those of interior decoration putty.

Exterior wall putty is generally applied 2-3 times, and the thickness of each pass should not be too thick to avoid cracking of the putty layer caused by high dry shrinkage strength. If you use Dajiang's special putty for exterior walls, the thickness of each pass should not exceed 1.5mm, and the total thickness of the putty layer should not exceed 3mm. The time between applying and scraping the front and rear putty should not be too long. The last putty should be applied after the front putty is dry. The putty layer should be polished in time after it dries.

3. Apply penetrating sealing primer

Sealing primer can seal the alkalinity of the wall, adjust the permeability of the bottom layer, and also increase the adhesion of the exterior wall paint coating. Focus on it, so you can't skip or brush in order to save trouble.

4. Exterior wall paint

The choice of exterior wall paint can be based on the desired effect, whether to use real stone paint, imitation stone paint, or liquid granite. For the choice of color, it is recommended to coordinate with the surrounding environment and the selected cultural stones; avoid being too bright, because the color retention of bright exterior wall paint colors is a test for big brands and is easy to fade; you also need to consider the local area Customs or Feng Shui issues.

Finally, for the construction of exterior wall renovation, special attention should be paid to the weather forecast and avoid work before the arrival of rain or snow. Only when the time is right, the place is right, and the people are right can we smoothly replace the old tiled self-built house with beautiful paint and new decoration, so that it can be worthy of its appearance!
