Interior wall putty plays a vital role in building wall decoration. With the improvement of people's quality of life and aesthetics, there are not only quality requirements for interior wall decoration, but also aesthetics. Good-quality and beautiful walls not only need good skilled workers, but also need high-quality putty powder as a guarantee.

Peeling between two coats of putty:

reason:

1. Before the first putty is completely dry, start the construction of the second putty.

2. The first putty layer is polluted. (Floating dust, oil, etc.)

3. The putty is not matched, that is, the strength of the first putty is lower than that of the second putty.

4. Use inferior putty.

Solution:

1. Thoroughly eradicate the peeled putty layer.

2. After cleaning the floating dust, use high-quality wall solids to paint and seal. (Wall solid can choose instant hydroxypropyl methylcellulose)

3. After the wall is solid and dry, choose high-quality putty for repair construction.

4. Correctly choose and match putty. Hydroxypropyl methylcellulose for putty powder has the advantages of high purity, strong water retention, easy construction, and less addition. It is an indispensable and important additive for high-quality putty powder.

Peeling between the putty layer and the base layer:

reason:

1. The base layer is loose and there is sand running.

2. The base layer is too smooth.

3. There is pollution on the grassroots level. (Floating dust, oil, release agent, etc.)

4. The base layer has been soaked in water for a long time.

5. When there is clear water in the base layer, the putty is scraped and approved.

6. Use inferior putty.

Solution:

1. Remove the peeled putty layer, and re-select high-quality putty for batch scraping.

2. For the severely pulverized construction surface, use high-quality wall solids to paint and seal them. After the wall solids are dry, repair the putty layer.

3. After the water-soaked wall is removed and dried in the sun, waterproof paint must be applied first, and then the putty layer should be repaired.

4. Correctly choose and match the putty. The putty is not matched, that is, the strength of the first putty is lower than that of the second putty. For the second putty, it is recommended to add redispersible latex powder to increase the lightness and elastic modulus of the putty powder. Redispersible latex powder can improve many minor problems of putty powder.
