The way to boost the normal water maintenance of putty in summer time

At the moment, it is about to enter in summer, along with the temperature is relatively higher. Especially in the upper area, the temperature is not only high but also the air is dried out. The surface temperature of your wall surface can achieve 70°C. Due to temperature, the powdery exterior wall putty often has very poor construction and peeling. Natural powder and other difficulties, the key reason is that due to substantial temp of your wall, water retention in the putty is not really good, therefore the normal water from the putty is quickly ingested or evaporated by the wall surface, so the putty can not be repeatedly scraped and contains the sensation of atmosphere pores and skin and natural powder removing. Hollowing and flaking may arise after layer. How you can improve the water preservation of powdery external wall structure putty, there are mainly the subsequent strategies:

Strategy 1: Raise the amount of cellulose ether

Cellulose ether has excellent drinking water retention. In summer, the volume of cellulose needs to be increased appropriately. The liquid retention performance of cellulose is directly proportional to the volume of cellulose added under certain situations. Increasing the quantity of cellulose can effectively enhance the putty. top quality.

Method 2: Boost the volume of lignocellulose

Lignocellulose has a specific water preservation effect. Adding wooden fiber content raises the drinking water retention capacity in the fabric, helps to make the material process hydrated uniformly, and might enhance the workability concurrently, however the drinking water preservation concept of lignocellulose differs from that of cellulose. It offers the characteristic of locks absorption. (H2o conduction), you will have dampness between each fibers, and once the dampness inside the encompassing atmosphere in the fiber content modifications and lessens, the dampness between the materials is going to be launched uniformly. Open time, quite difficult to crack.

Technique 3. Increase the volume of polymer

On wall space where the putty is comparatively slender, air is free of moisture and also the heat of your base is great, to create the putty have frequent scraping components, one of many far better techniques is usually to raise the volume of polymer, and redispersible latex powder can be extra appropriately. Boost the repeatability of putty and increase the lighting of putty.
