How much impact does flexible putty have on the wall?

The impact of flexible putty on the wall is very important. Compared with ordinary rigid putty, flexible putty has better performance and quality, can effectively prevent the tape at decorative seams from sticking off the primer, and has higher crack resistance. It has strong two-way bonding with base layer and primer, which can significantly extend the life of textured paint.

Rigid putty is often called P-type putty, while flexible putty is called R-type putty, and they are different types of products. The main difference is the putty's resistance to cracking, also known as dynamic cracking resistance. The dynamic cracking resistance of flexible putty is more than twice that of rigid putty. Most putty products on the market are rigid putty and their crack resistance is relatively poor. After about 3 months of construction, obvious spider web-like cracks will appear on the wall, also known as cracks. After using flexible putty for construction, due to its good performance, there will be no cracks caused by the putty itself. The dynamic cracking resistance of high-quality flexible putty can reach more than 0.08 mm, which means that the putty can cover micro-cracks of more than 0.08 mm, and no cracks will appear in appearance. Simply put, flexible putty has better flexibility and ductility, and is relatively soft, while rigid putty has a higher cement content, is harder, and is prone to cracking.

The construction method of flexible putty is similar to that of rigid putty, but it should be noted that the drying time of flexible putty is longer than that of rigid putty. In the early stages of construction, flexible putty may feel very soft, and some workers may worry that the putty will fall off. However, this worry is unnecessary, because the adhesive force of flexible putty after construction is very strong. Compared with rigid putty, flexible putty construction is smoother, and workers' construction speed can be increased by about 2 times. Flexible putty has excellent construction performance and is very smooth and effortless when scraping, which can significantly improve workers' work efficiency. Especially when labor costs are high and material costs are relatively low, worker benefits are very important.

The following is the construction process of flexible putty powder:

Base treatment: The surface of the base material must be solid, smooth, and free of oil, floating dust and other debris. If there are peeling, powdery, hollow, loose and other areas, they need to be removed. For porous materials or substrates with too high surface temperatures, the surface should be lightly moistened before application.

Ingredients: According to the ratio of water and flexible putty powder to 1:3 (mass ratio), first pour 1 part of clean water into the container, then add 3 parts of flexible putty powder, and use an electric mixer to stir into a uniform paste without particles. . Let it sit for 3 to 5 minutes and stir again before use.

Scraping and polishing: Use a spatula to scrape 2-3 times. The thickness of each scraping is about 0.5-1mm. The next batch of scraping can only be carried out after the previous putty layer has dried. After the last putty layer is completed, it should be polished within 1-2 days, but do not polish too early to avoid affecting the strength of the putty. About 5-7 days after the putty layer is completed, the surface coating can be applied. If early construction is required, an alkali-resistant sealing primer should be used for back-sealing.

In short, flexible putty has a great impact on the wall. It has excellent crack resistance and ductility, and can effectively prevent the occurrence of cracks. During the construction process, flexible putty has excellent construction performance and can improve work efficiency. Therefore, when carrying out exterior wall projects, it is recommended to use flexible putty powder for construction.
