What should we do if the seamless wallcovering is bulging and blistering after being pasted? To solve the problem, we must first understand the cause of blisters and treat them fundamentally.

There are many reasons for wallcovering blistering, which can be summed up into three categories:

First, the wall itself is too uneven, difficult to repair;

The second is caused by the construction process;

The third is after the completion of construction, because the wall breathable or wallcovering expansion and other reasons lead to bubbling, wrinkling and so on.

01

Uneven wall surface

The wall surface is not flat, if not timely treatment is easy to cause the phenomenon of bubbling after it is pasted on the wall..

Advice:

Before sticking seamless wallcovering, white cement and old powder should be mixed as the putty of indoor wall, so that the wall is solid and smooth, handle the internal and external corners..

After leveling the wall, brush the base film, because the base film has a good function of maintaining the wall , and is waterproof, moisture-proof and mildew-proof, thereby inhibiting the bacteria on the wall and extending the life of the wallcovering.

02

The glue collocation is not reasonable

In the process of construction, the unreasonable collocation of slurry leads to the phenomenon of bubbling on the wallcovering.

Advice:

Before construction, the proportion of slurry and rubber powder is very important. Different wallcovering, demand ratio is not the same. Make sure you read the instructions.

In general, manufacturers suggest that the ratio of rubber powder and glutinous rice glue is 2 to 1, that is, 2 bags of rubber powder +1 bag of glutinous rice glue.

The prepared glue shall not be too thick, too thick will cause the glue uneven scraping and wrinkling phenomenon; If the preparation is too thin, the wallcovering will not stick and the whole wallcovering will fall off. Therefore, pay attention to the proportion of glue powder and glutinous rice glue and the proportion of water added when mixing and preparing glue. Experienced master can judge the consistency only with the naked eye.

03

Late foaming and wrinkling

Blisters and wrinkles often occur due to wall ventilation or swelling and shortening of the wall fabric.

Advice:

Faced with this situation, don't worry. For blistering, you just need to poke a small hole with a small needle to release the air inside. If there is a depression after deflating, it can also be adjusted by injecting an appropriate amount of glutinous rice glue.

Tips:

We must pay attention to checking the wall surface before measuring and mounting the wallcovering to avoid unnecessary loss and trouble.
