When renovating an old house, how can you quickly remove putty from the walls?

821 water-resistant putty cures well, is insoluble in water, and the wall can be scrubbed clean with clean water if it is dirty, which has the effect of moisture-proof and waterproof. Water-resistant putty needs to be scraped three times, the first time to smooth the wall, and the last two times to also smooth and whiten. Water-resistant putty dries relatively quickly, in fact, the inner wall will also be hung with steel wire mesh, and the wall hanging mesh is usually divided into two kinds, one is to hang steel wire mesh when plastering, which is to hang the net at the junction of different walls, which can prevent different walls from cracking under thermal expansion and cold contraction.

<> damp, moldy and alkali back walls. Find the cause of moisture, due to waterproof leakage caused by the wall alkali return, wall treatment, no solution! Unless the leakage point is redone on the inside of the waterproofing to prevent leakage.

Moisture and alkali return caused by simple weather reasons, an appropriate amount of oxalic acid is served, and before the wall is mended according to the regular after neutralization and drying, it is necessary to make sure that the material is sufficient: the wall plaster is mainly used to repair and fill the wall damage, potholes, cracks, peeling, blistering and other incomplete wall problems. Wall paint is mainly used to protect and repair walls, cover soiled wall renovation.

For the renovation of the wall, the old wall is still shoveled off, if you don't want to shovel off the wall, just want to do repairs, but the use of Qinglong strong surface repair paste, you can repair it to the original, or use Qinglong wall solid, the overall improvement of the waterproof quality of the wall! I just did it myself, and the original peeling and loose ones have to be shoveled, and the ones that don't peel don't need to. Shovel knocking, hollow drum to dig clean, if digging to the base, found that the ash is loose and loose, you can go to buy sand without a trace according to the instructions to adjust the water and spray it in the place where the ash and sand rise.

If there is serious peeling and many cracks, it is recommended to shovel it off and do it anew, you can brush the wall solid, and then Nizi leveling, drying on both sides, and then brushing latex paint. If the area is moldy, hollow, cracked, etc., it is recommended to shovel off all the old wall skin. If it is a small part of the cracking and hollowing, shovel off a small part, and then use cement mortar to repair and level it with a batch of Lebao putty powder to paint it twice, or it has not lived for a few years before changing hands, since it is good, why must it be shoveled.

Before shoveling the wall putty, you can first wet the entire wall with a water gun, put the wall putty wet for about 30 minutes, and the wall putty can be easily removed after soaking it softly.

You can buy a large shovel to scrape the putty off the wall, which is generally solved in 10 minutes.

Before shoveling the putty on the wall, first brush it with clean water, and after soaking in water, you can quickly remove the putty.

1.The walls of the old house, if not shoveled, can you directly scrape the putty.

It depends on the situation: First, the wall foundation is good, there is no glue paint, no blistering, and it can be scraped directly.

Second, on the contrary, it is better to shovel it from scratch.

2.Blank wall, can you scrape putty directly and also use an interface agent.

? This depends on the specific situation of the wall, some developers cut corners and use the cement mark in the mortar when plastering the wall.

If such a wall is best brushed with a layer of base film, so that the mortar that is easy to fall off the wall can be fixed, and then scrape the gypsum powder.

When scraping gypsum powder, an appropriate amount of milky white glue should be added.

The plaster powder should be flattened after completion, and then the putty powder should be scraped.

If the wall mortar falls off seriously, it is necessary to dispose of all the wall and re-plaster the wall, otherwise it is not possible to brush the base film, and it will bulge in 1-2 years, resulting in cracking and falling off the wall skin. The condition of the wall is the key to deciding what to do.

3.Before scraping putty, does the roof wall skin need to be shoveled off?

Carefully check whether the cracks are hollow on both sides, if they are very strong, there is no need to eradicate them, just scratch the opening and fill it with putty. Yes, there is no need to scrape putty. You can completely save the process of scraping putty (provided that the wall surface must be flat and free of hollowing and cracking).

If you scrape putty on the paint, it will definitely not be strong, and even if you paint the wall, it will be too thick (your workers are not honest enough).

Remember, if you must scrape putty for leveling, you must shovel the original putty, otherwise do not shovel putty (a small part of the repair can be), polish the original wall, brush the wall solid, brush the paint.

Answer: The wall of the old house, if you don't shovel it, you can't scrape the putty directly. Because it is easy to scrape the new putty without shoveling off the dust on the old wall, it is easy to fall off the new putty.

It depends on the condition of the wall. If the wall is just dirty, there is no problem with scraping putty directly. If the wall has peeling skin, it should be shoveled.

No, the putty scraped directly in this way is not sticky, and it won't take long to fall off, and then it will be troublesome, so let's shovel off the putty of the old house first.

The walls of the old house must be shoveled off the old wall skin first, and then the putty can be scraped again. Otherwise, the putty on the melon will fall again.

If you want to redecorate the old house, the stucco on the wall should be completely removed, and the direct scraping of putty is equivalent to doing it in vain, and in the end there will still be all kinds of problems.

The specific ways to quickly remove putty or paint from the wall of an old house are:

1. Spray water twice with a sprayer or roll both sides with a paint stick, and the wall can be easily removed with a shovel after it is wet. However, you can also try it partially, if you can't shovel it, it means that the original wall is good, and you can polish it with sandpaper.

2. Wipe off the dirty parts with dish soap first, and then wipe the dirty parts with clean water, including the surrounding part, so as to ensure that the wiped parts will not have obvious color difference with the original paint surface. If there are still traces, you can go to the stationery store and buy a "high-end painting eraser" (the translucent kind) and wipe it clean with a few wipes.

3. Take a fine sandpaper to polish the dirty place, and light the place where you wipe, and focus on polishing the dirty one. If it is a colored latex paint, you should pay more attention to the strength when sanding to prevent excessive sanding and exposing the bottom.

4. The shovel blade is the kind that can replace the art blade, so that the wall absorbs water and wets the wall, and before the wall is produced, the wall is rolled several times with a roller dipped in water, and it is easier to shovel it after a while.

Wall planer. Wall planer, also known as wall shovel machine, old wall renovation machine, rough planer, is mainly used for wall uneven repair, old wall renovation treatment.

The principle of woodworking planer, but the cutter is different. It uses multiple rotating diamond bits to remove the coating from the original wall. Two-handed handle operation, fully built-in bitterhead, easy and safe.

Series motor, small size, light weight and strong efficacy; Belt drive, maintenance of Jianling Li Dan, no dead angle in the working area Xun Zheng; The cost of consumables is low, and the life of the working cutter head can reach 5000 square meters; **Only a few hundred yuan, it is really a weapon for the renovation of old walls.

Putty is the putty on the old wall, of course, to shovel off, do not shovel off the old putty wall and the new putty can not be combined, will produce the phenomenon of wall skin falling off or bulging, must be shoveled to the bottom of the cement and then use glue and putty to stir, as a base use, wait until the bottom layer is completely dry, and then scrape the putty operation, so that the wall skin will not be peeled when it encounters water.

1. When scraping putty, the wall must be in a dry state, fill the cracks and holes at the bottom layer, and then scrape the putty after filling, so as to prevent the holes from drying and cracking the putty layer, when the first layer is scraped, it should be dried after thorough drying, sandpaper is used for sandpaper, the second layer of stucco is painted, and the putty is generally operated three times to make the wall smooth and smooth.

2. Putty is elastic, the second layer should not be applied before it dries, in case the wall cracks, when the first layer is dry, the second layer is smeared, even if the first layer is dry, there will be a second layer to make up, in the continuous polishing, the subtle cracks will be polished clean, so that the wall is in a smooth state.

3. The ratio of putty to water is that it must be stirred more than three times before it can be used on the wall, and the putty can not be used overnight.

We should apply some laundry detergent so that it can be removed well, and we should also spray some perfume so that the house will smell special.

In this case, I recommend you to use an angle grinder, which can remove the putty from the wall in a very short time.

There is a lot of putty on the tiles, the area is large, and the floor can be mopped with a daily mop. The step is to soak the mop thoroughly, and then wipe the putty with a dry towel with a rough surface that has fully absorbed the moisture.

The quickest way is to get a professional to deal with it, because they know the technology, they know the way, they know the fastest way.

We can use those shovels to do this and keep banging on the walls, so that the powder on the walls will fall off quickly, and we can use other knives to get the powder.
