Renovation skills of old walls and old houses have become new and simplified.

If the house was built in the 1980s, 1990s and 00s, as time goes on, old walls will begin to appear. Once the wall is old, it will inevitably have a certain impact on its appearance, giving people an old and broken feeling and affecting the living experience. In order to solve the problem of the old wall, we can renovate the old wall, let it be swept away and become new again. Here are some related knowledge about the renovation skills of old walls.

Old wall reconstruction skills

Part 1: clean up the old wall.

The basic treatment of the old wall includes cleaning the original latex paint and putty layer on the old wall, wood decoration and removing other surface decoration (such as wallpaper). If the wall is only decorated for one or two years, you can get rid of the putty on the wall, polish the wall with steel brush and sandpaper and brush the latex paint again. If the decoration takes a long time, it is necessary to remove the putty layer before the subsequent process. Remember that the old wall surface must be treated, not directly painted. After the severely pulverized wall is removed, apply a layer of white cement and then paint.

Part II: Startup

The function of wall primer is alkali-resistant and moisture-proof, sealing the substrate, protecting the topcoat and improving the texture and hiding power of the topcoat. If the top coat is directly applied without primer, the wall will be prone to foaming and mildew after a long time, and the wall will also change color under long-term sun exposure.

Part III: Large-scale restoration

Repairing the wall with a good finish will be more troublesome and prone to color difference. It is difficult to guarantee the quality of materials with different use time, and it is difficult to achieve the ideal effect. Therefore, it is best to repair the whole wall together to avoid color difference as far as possible, and the quality of the repaired wall will be better.

Part IV: Anti-chromatic aberration

When repairing the wall, try to avoid color difference, so pay attention to the proportion and painting of paint barrels, and it is best to estimate the dosage. Prepare enough quantity at a time, so as to ensure the consistency of wall color and avoid the difference of re-allocation color caused by insufficient quantity.

Matters needing attention in wall decoration

Water-resistant putty that has been used for more than five years must be removed to the bottom of the wall during the secondary decoration due to the aging of the material, otherwise it will affect the construction quality of wall latex paint and the long-term use effect after decoration.

The ventilation condition of the old house is poor, and the xylene component in the diluent will react chemically with the components in latex paint, resulting in yellowing of the wall. Therefore, it is necessary to strengthen ventilation, open more doors and windows, or put a few electric fans to enhance the ventilation effect.

In addition, while carrying out space transformation, we should understand the wall characteristics of the house. The load-bearing walls must not be destroyed in the decoration, and some non-load-bearing walls cannot be removed at will, otherwise it will have a serious impact on the safety of the house.

How to distinguish load-bearing walls? Generally, according to the annotation on the engineering drawing, the thick solid line in the construction drawing and the wall under the non-load-bearing beam in the ring beam structure are load-bearing walls, and the non-load-bearing walls are generally marked with thin solid lines or dotted lines on the drawings. In addition, it can also be distinguished according to the thickness of the wall. Generally, walls over 240MM are load-bearing walls.

Some walls can't tell the thickness, but they are also load-bearing walls, such as the outer wall and the wall used by neighbors, which is easy to tell.

The old wall reconstruction skills are as above. Mastering the skills of old wall renovation, and then completed by a professional decoration master, can often make the wall novel in a short time and give you a brand-new living environment. If the home is an old wall, try this transformation technology. At the same time, I remind you that before rebuilding the old wall, you need to see clearly what your own price is, and then complete the renovation work after determining the price, so it is not easy to have disputes with the other party.
