Reasons for the glue penetration on the wall
Analysis of the reasons for the penetration of glue
1. The glue is too thin
This reason should be well understood by everyone: the glue is too thin, and the water in the glue will pass through the composite layer with part of the glue and appear on the surface of the wall covering.
2. The glue is too thick
This reason is also easy to understand: when the glue concentration is moderate, too much glue will cause unevenness on the wall. At this time, inexperienced construction masters will generally squeeze the glue to the edge for smoothness.
The glue was squeezed, and through the wall covering, the problem appeared.
3. Improper use of tools: scraper
This reason is the culprit of most glue penetration problems: in actual construction, the glue on the wall cannot be completely in the theoretical state, so when the glue is in a moderate concentration, the glue will be more or less, and there will still be excess on the wall. glue.
The tools used at this time are a very important part. If the scraper is vigorously backlogged against the wallpaper, there will be a phenomenon of glue penetration.
4. Impatient wall construction
The reason for this is that the construction requirements are higher, or the main problem of glue penetration is the wallpaper with delicate material. Patience is all the more important when neither glue nor tooling is an issue.
When the glue has just been applied to the wall and the moisture content is still too large, the inexperienced construction master will choose to immediately attach the wall covering to the wall in order to receive the construction cost as soon as possible.
At this time, a similar high-precision wall covering will have a problem of glue penetration.
1. The proportion should be appropriate when making glue
Take glutinous rice glue as an example, add water in a ratio of 1:1. After mixing, the glue can be attached to the drum without running off quickly and can still be retained on the drum. The glue works best at this point!
2. The glue on the wall should not be excessive, and attention should be paid to the inner corner
When brushing glue, it is required to apply thinly, and the glue should not be too much or too thick! When brushing glue in the inner corner area, it is enough to apply a thin layer of glue, because during construction, most of the excess glue on the wall will be brushed to the inner corner, so the glue at the inner corner is not required. a lot of.
