Do you need to shovel the original wall for the renovation of the old wall, and how to repair the se

The old wall is prone to yellowing and cracking after long-term use, which affects the interior appearance. Now, it needs to be refurbished. First, sandwork the surface of the old wall with sandpaper or steel balls to make it smooth and flat, and use a damp rag to clean the dust and dirt from the surface of the old wall.

The surface of the old wall is painted with a layer of anti-crack reinforcement paint. Anti-crack reinforcement coatings can penetrate directly into the interior of old walls, so that the internal structure is better bonded together and reinforced.

Stick a new layer of wallpaper on the old wall, or repaint it with latex paint. If you use latex paint, you usually need to use it about 2 times, and each time it needs to be completely dry before you can continue to use it. At the same time, it must be applied evenly and not too thickly, so that the wall decoration effect will be better.

Before renovating an old wall, we need to be ready to use tools such as shovels, rollers, sandpaper, and other materials. It is also necessary to prepare enough paint to avoid inconsistent colors of the paint purchased in the future, and then mix it appropriately.

The old wall must be treated with a base layer before it can be renovated. If the wall is badly chalized, you need to remove the painted surface with a shovel and then paint it with white cement. If the surface of the old wall is smooth, it needs to be sanded with sandpaper to remove the unbonded paint film so that it can be applied later.

After the old wall base is treated, putty can be used. In this link, it should be noted that the thickness of the putty should be uniform. In general, it should be applied 2-3 times before polishing.

After it is completely dry, the primer should be applied again. The primer has a good moisture-proof effect and is also conducive to the adhesion of the topcoat.

Two topcoats should be applied for construction. The second topcoat can only be applied after the first topcoat has been applied dryly. The paint film should be uniform and the thickness should be the same.

Whether or not an old wall renovation requires a shovel depends on the specific wall conditions. In general, old walls that need to be renovated will have common wall problems such as wrapping and spalling. Therefore, it is best to fully doze the walls before renovation to ensure flatness and compliance for later construction.

The original wall needs to be flattened, because this can be better decorated, and it can also be decorated with a new feeling, if the damage is very serious, we can use some steel frame to support.

I think of course you need to shovel off the old wall, and if the damage is serious, you can first smooth it with cement, and then paint it with white or wall paint after it is dry.

You can find a professional maintenance worker to repair it, or understand the damage of the wall, or you can repair it according to the actual damaged area.

If necessary, be sure to remove all the damaged parts, and then go to dry the urine in time, and then apply a layer of paint after drying it thoroughly.

If there are cracks in the old wall, it is best to repair it before the painting is applied, usually with plaster or glue to fill it. If there is a large area of cracking on the wall, it is recommended that the entire wall should be repaired, which can effectively avoid the collapse of the color difference problem, and the repair effect will be more prominent.

3. Paint brushing. After the base of the old wall is treated, it is necessary to scrape the construction of putty, generally scrape 2-3 times, and then polish it. After it is completely dry, it is necessary to carry out the construction of the primer, which not only has a good moisture-proof effect, but also facilitates the adhesion of the topcoat.
