Use method and difference of usual internal wall putty powder
Specific operation methods of internal putty powder and water resistance wall putty
What is the specific operation method of putty powder during application? What is the difference between normal internal putty powder and water resistance wall putty in the market? Putty powder mixer manufacturer Henan Ant Constructions will give you an in-depth analysis.
a. Inspect the wall, process the hollows and cracks, remove the loose base layer and old coatings that are damaged, powdered, and peeled, and then roll the "interface treatment adhesive" after removing the floating dust. If the wall surface is slightly powdered and loose, you can also roll the "interface treatment adhesive" directly on it without removing the base layer.
b. Open the package, pour the putty into barrel, pick it up with a ash knife and place it on the scraper which can be scraped back and forth.
c. Due to the high solid content, it is convenient for wall treatment and correction of male and female angles. The appearance of the paste is slightly dry, but the thixotropy is good. The ash knife can be cleared by scraping on the wall once or twice. Dryer materials can be cleaned by kicking outside the inner packaging bag with your feet or stirring with a trowel, and scraping freely.
d. Water can be added appropriately when the material is dry. It will be easier to push and scrape after adding water, but the ability to fill and supplement the angle will decrease, so be careful.
e. After the package is opened, it should be used up as soon as possible. The remaining materials should not be exposed to the air and must be sealed and stored.
f. The thickness of one batch scraping should be less than 0.5mm, and the curve deviation greater than 2mm should be leveled with "filled angle putty". For large area, fill in the inner wall filler putty powder to level the closed wall, and use the inner wall filler putty to level the closed wall. "Corner putty". Never use plaster powder mixed with glue to treat walls.
g. For lime wall or alkaline wall, apply "filling angle putty" once again.
h. The next batch of scraping can only be carried out after the first batch putty completely dried. The number of scraping depends on the smoothness of the wall, generally 2-3 times. The wall must be painted within one week after wall putty has dried.
There are many normal leveling putty powder and water-resistant putty on the market. The main component of normal leveling putty powder is mainly calcium carbonate. After years of use, it has shown many fatal shortcomings. Water-resistant putty is a high-quality substitute for normal leveling putty powder.
Disadvantages of normal leveling putty powder:
a. Poor adhesion and low bonding strength.
b. Poor flexibility.
c. Chalking will appear soon after encountering moisture.
d. Easy Cracking, peeling, shedding in a short time. Especially for the treatment on the inner wall moisturizing board, it is difficult to prevent even it is fully enclosed with cloth. After the construction is completed, multiple maintenance will be brought, which will cause inconvenience to customers.
e. When painting the wall again, the original old putty needs to be removed, which is laborious and pollutes the environment.
f. The surface is not delicate enough and the texture is poor.
Advantages of water-resistant putty:
a. Strong adhesion, high bonding strength, good flexibilty and good air permeability.
b. There will be no chalking after being damp, and it has strong water resistance.
c. When using water-resistant putty, the wall will not crack, peel, fall off, etc.
d. The wall with water-resistant putty has a delicate touch, a soft look and a good texture.
e. After the wall with water-resistant putty is polluted, it can be directly scrubbed or directly painted with interior wall paint. And can improve the performance and service life of latex paint.
f. When painting the inner wall again, you don't need to remove the wall and directly paint the inner wall paint. Therefore, water-resistant putty is the bonding layer of wall and latex paint.
