Who's wrong with the wallcovering penetrating glue? Is it the quality of the wallcovering? Is it the glue? Or improper construction? First of all, let's analyze the reasons for the glue penetration of the wallcovering.

01

Reasons for glue penetration

1. The glue is too thin

If the glue is too thin, the moisture in the glue will carry part of the glue through the composite layer to the surface of the wallcovering. (Poor quality glue may also cause penetration.)

2.The glue is too thick

If the glue is too thick, the wallcovering will appear uneven. At this time, inexperienced construction masters will generally squeeze the glue to the edge. During this process, the glue will penetrate the wallcovering because of being squeezed strongly, resulting in artificial glue spillage.

3. Improper use of tools

In actual construction, the glue on the wall cannot be completely in the theoretical state, so there will be excess glue on the wall when the glue concentration is moderate. The tool used at this time is a very important part. If the scraper is vigorously backlogged to the wallcovering, there will be glue penetration.

4. Rush to get things done

This reason is the main reason for the glue penetration problem of wallcoverings with high construction requirements or delicate materials. When the glue has just been applied to the wall and the moisture is still too large, inexperienced construction masters will choose to attach the wallcovering to the wall immediately in order to receive the construction cost as soon as possible. At this time, high-precision wallcoverings will have glue penetration problems.

5. Improper treatment of internal corners

Internal corner refers to the recessed corner on the wall. During the construction in the internal corner area, it is best to remove some glue liquid with a small brush first, leaving only a thin layer, which can effectively avoid the penetration of glue in the internal corner.

Treatment of glue penetration

1.Thermal sol wallcovering

Hot sol is generally not easy to penetrate the glue, but once the glue penetrates, there is almost no way to deal with it. The hot glue that penetrates the glue feels hard to the touch. Generally, you can try to brush it with a small brush, but the effect is not obvious. It is not recommended to repair large-scale glue penetration.

2.Non-woven wallcovering

Once the non-woven fabric penetrates the glue, the glue is easily diluted with water and enters the non-woven fabric fibers, so the glue marks are difficult to clean. The following is the treatment method of small area glue penetration.

● Just after the wallcovering is pasted, do not wash with water before the glue mark is dry. Use a clean dry towel to absorb the water. You can't wipe it, you can only absorb it, so as to avoid expanding the scope of pollution.

● If the glue marks are dry, use a clean eraser or white towel to erase them.

● In the process of construction, it is necessary to avoid the occurrence of glue leakage as much as possible. If glue seeps accidentally, it must be dealt with in a small area in time.

Warm prompt

If the glue and construction reasons are excluded, then the glue penetration of the wallcovering may be the reason for the quality of the wallcovering itself. When glue penetration occurs in a large area, the construction should be stopped immediately, the problem should be reported to the merchant, and the reason for the glue penetration should be analyzed and found.

The prevention methods

1. The proportion of water and glue should be appropriate

First of all, you must not use inferior glue. When brushing glue, thick glue is required to be applied thinly, and the glue should not be too much and too thick. Take wet glue as an example, add water according to the ratio between 1:0.6 and 1:1 (the ratio of adding water is different for different thick wallcovering), the glue can be attached to the roller after modulation, and the glue effect is the best at this time!

2. Use a short-bristle brush for construction

When working on large areas, be sure to use a short-bristle brush instead of a scraper after the wallcovering is applied to the wall! The contact surface of brush and wallcovering is larger than the scraper, the bristles is soft, and will not produce strong extrusion on the wallcovering, and will not leave scratches, hook wire and other damage to the wallcovering phenomenon. In addition, pay attention to the gentleness of the construction method, generally will not cause glue penetration.

3. Slow work makes fine work

After the glue is applied to the wall, the construction master should be patient. Construction can be done after 15 minutes, the purpose is to let the excess water in the glue evaporate some. Doing so can greatly avoid the glue penetration of silk-textured wallcoverings or the glue penetration due to excessive moisture!

4. Pay attention to internal corner construction

When applying glue to the inner corner area, just apply a thin layer of glue. Because most of the excess glue on the wall will be brushed to the inner corner during construction, there is no need for a lot of glue at the inner corner..
