First, look at the packaging.

Carefully check the brand, model, product implementation standards and whether it is under warranty.

Second, look at performance.

1. Smooth and delicate

Some tiny sand marks will be formed after putty is polished, which is beneficial to the adhesion of latex paint. However, if the sand mark is too thick, latex paint is difficult to fill and cover, which will affect the smoothness of the coating surface.

2. Adhesive strength

Good putty powder (water-resistant putty) has a service life of more than 15 years after being scraped on the wall in normal batches. Ordinary putty powder can only be used for 5 years under the protection of exterior wall latex paint.

3. Good water resistance

This is an important sign that determines the quality of products. Products with strong water resistance not only have good adhesion under moldy and humid conditions, but also are of great help to the film formation of coatings themselves.

4. Environmental protection

In home decoration, putty powder accounts for 80% of the total decoration area. If the product is not environmentally friendly enough, living indoors for a long time will affect people's physical and mental health.

5. Constructibility

Good products are well-structured, easy to polish, and not easy to crack in batch thickness.

I hope I can help you, and I hope to adopt it!
