What kind of putty should be used to renovate the damp walls of old houses

Thank you for your trust, and personally put forward some views on this issue for your reference; The first floor is generally damp, but there should be room for improvement; e.g. whether the branches outside the building can be pruned; Whether the drainage ditch outside the building can be dug deeper, at least lower than the indoor ground; Open more windows on sunny days, etc.; (Find out more about the reasons and improve it from the source), usually put lime bags in some corners, dry tea leaves in the cabinet, etc., and dry the sun on sunny days; Try not to touch the wall of furniture; , the wall production shovel off the old stucco layer, etc., after drying with a layer of cement mortar powder, a batch of moisture-proof putty dry and then use the bottom cover, dry after the normal batch of putty, dry after grinding, rolling latex paint;

1. The first floor is generally relatively humid, but there should be room for improvement; e.g. whether the branches outside the building can be pruned; Whether the drainage ditch outside the building can be dug deeper, at least lower than the indoor ground; Open more windows on sunny days, etc.;

2. Usually put lime bags in some corners, dry tea leaves in the cabinet, etc., and dry them on sunny days; Try not to touch the wall of furniture;

3. Shovel off the old stucco layer of the wall, etc., use a layer of cement mortar powder after drying, batch a moisture-proof putty and then use 108 and other backings, and then use a normal batch of putty after drying, polish after drying, and roll latex paint.

Well, I agree with the foreman's statement, the current putty powder is generally directly mixed with water and batched, and some are mixed with some glue, but it is not good for construction, it is difficult to dry out, and the effect of batching is not good, although it is strong but not smooth enough. So the kind that the foreman said was the best thing to do.

First, first use 108 glue to close the base layer.

Second, use water-resistant wall lining for leveling.

Third, use a moisture-proof primer on the surface first, and then use a better coating.

The first floor is particularly damp, and the ground is often flooded with water vapor, so you must use a special exterior wall putty powder mixed with water to batch it, otherwise it will be moldy in three or five years.

Waterproof putty, it is not afraid of moisture and is not easy to fall off.

The old house that has been lived in for a long time will be particularly damp due to disrepair, and there are places on the wall that are moldy, blistered, and even peeling off the wall, which are caused by the dampness of the wall, so how to solve these problems is a headache, so we will take it belowHow to decorate an old house when it is dampHow to decorate an old house when it is damp

First, mold, because the room is too damp, or long-term water immersion, the wall is prone to spot mold, or a large area of mold, and some may even grow moss, second, for the moldy treatment of the wall surface, you must first scrape off the moldy wall with a scraper, clean the wall that has been scraped off, and apply the adjusted putty powder. After the putty is dried, apply lime. Lime can absorb moisture.

Keep dry; The walls are then painted with waterproof paint and latex paint, and then polished again.

Some ways to damp old houses.

1.Sometimes blister-like protrusions appear on the walls, and they also contain sand grains. The cause of blistering on the walls is that too much pigment is added to the paint preparation or mixed with debris, and the brushes, rollers or spray guns are not clean; Before the paint surface dries completely, moisture penetrates into the paint and causes the paint film to lose its adhesion.

2.In order to solve the problem of blistering on the wall, first of all, it is necessary to avoid painting in humidity or weather, and secondly, the time interval of the number of late brushing times must wait for the putty or paint film to dry and apply a layer of paint, and clean up the construction environment before painting construction.

3.When bubbles appear on the wall, the peeled part of the blistering should be removed first. Local wall foaming can only be partially scraped, the edges of the scraped part are smoothed, and then primer is applied and then recoated. Brush once; If it is a large area of foam, it must be scraped off and wait until the wall is dry.

4.Sometimes after the decoration is completed, a piece of putty will float and fall on the wall, mainly because of poor construction technology, putty, paint adhesion and shrinkage performance.

5.The quality of the construction process requires a professional construction team and experienced construction personnel. This reminds us to be cautious when looking for a renovation company.

6.The solution to this problem requires the reinforcement of the base layer. After shoveling the wall surface of the peeled area, completely remove debris from the wall surface and repaint the putty and lacquer.

7.Interior wall latex paint has high requirements for scrub resistance, and it is easy to stain the wall in home life, so it can be wiped with water at any time.

8.The cause of wall cracking can be due to the shrinkage of the putty. In the construction, the first putty is not dried and the putty is scraped again, and the second putty is not dried and the paint is brushed, resulting in cracking of the back layer of the putty.
