Ready to decorate the new house, the developer of the living room of the rough house has been whitew

Whether the original wall of the rough house needs to be removed needs to be comprehensively considered in combination with the condition of the wall and its own decoration needs.

Specifically, the following three main aspects are noted:

1. What is the water resistance of wall putty?

If the putty of the original wall has poor water resistance, there will be problems such as wall peeling, ash dropping, delamination, mold and other problems in the later use process, which will affect the daily use and appearance.

The method of judging the water resistance of putty: pour water on the putty layer on the wall, and then rub the wall with your fingers, if there is white paste on your hands or the wall is paste, it means that the water resistance of the wall putty is poor; If there is no white paste on the fingers and the wall surface is intact, it means that it has good water resistance.

2. What is the curing strength of the gypsum plaster layer of the wall base.

If the curing strength of the wall gypsum plastering layer is poor and there is a problem of hollowing delamination, it will also cause the problem of wall cracking and delamination in the later stage, and it is recommended to eradicate it.

3. Your own decoration needs.

If you are ready to rent it out and there is no hollowing delamination problem in the wall treatment, you can apply the primer and topcoat after the interface agent is applied to the wall. For rental, there is no hollowing and delamination problem in the wall treatment, and the wall can be coated with an interface agent, and then a primer and topcoat can be applied.

The experience room confirms that the putty is intact and can not be removed, and if there is cracking and hollowing, it needs to be treated.

Hello! If you don't paint the general developer, at most you will scrape the white, that is, scrape putty, so when you decorate yourself, you need to seal it with 801 glue first, so that it will not be depowdered. Then scrape the putty twice and then brush the paint after sanding it clean, and you don't have to try other detours to avoid wasting money.

I wish you success!!

There is no need to shovel, it is better to scrape putty after rolling a layer of 808 glue!

My house has just been installed, and it's the same situation as yours. I didn't shovel it off, and I brushed a layer of latex paint directly with solid glue on the wall, which saved trouble and money.

See if the wall surface is strong, that is, whether the white powder will fall off when you touch it. If not, it means that the putty layer is firm and can not be removed; If there is obvious white powder ash sticking to the hand, it means that the surface is not firm and needs to be removed and then re-putty.

However, regardless of whether it is eradicated or not, before the putty is re-applied, the construction glue (such as 801, etc.) should be rolled and brushed, so that the original wall plaster layer can be reinforced, which cannot be ignored.

Whether you can directly brush latex paint, in addition to the above, it also depends on whether the current wall is flat, but in any case, it must be sanded by sand skin before rolling latex paint.

You have to see if the walls of your home are solid, whether they are flat, with your hands.

To the touch, if there is obvious white ash sticking to the hand, it means that the answer surface of the table is not firm, and it needs to be shoveled and then re-batched putty.

Before the putty is batched again, the construction glue is rolled and brushed, which can strengthen the original wall plaster layer, which cannot be ignored

It is best to remove it and scrape the putty again.

No, putty is the most basic treatment.
