Compared with ordinary putty, water-resistant putty has the following characteristics in addition to good water resistance:
1) White and delicate, feel good
After the water-resistant putty is applied, the surface is smooth and delicate, and the putty after the light-receiving treatment will give a smooth and delicate feel, and the decorative effect can be used as a decorative layer.
2) Durable, no need to eradicate the second decoration
Ordinary putty is poor in water resistance. In the future, it must be cleaned up together with the original paint, and then putty putty again. Not only does the cost increase cause waste of resources, and the cost of decoration (materials and labor costs) increases, and the waste that is removed is difficult to recycle and pollutes the environment. The water-resistant putty is once and for all. After several years, after two, three or more renovations, it is no longer necessary to shovel the putty layer, polish the surface layer, and partially repair the next step, etc., saving time and effort and protecting the wall. body. Usually good water-resistant putty ensures the same life as the wall.
3) Save on coating usage
The unique whiteness and density of the water-resistant putty make it possible to save 25-30% of the coating amount per unit area of ​​paint adhesion and hiding rate compared to the wall using ordinary putty.
4) high bonding strength
JG/T298-2010 "Building Interior Putty" standard has a clear definition of the strength of putty. The standard state bond strength of ordinary putty is greater than 0.25 MPa, there is no requirement for the strength after immersion, and the water-resistant putty requires standard state bond strength. It reaches 0.50 MPa and the bond strength after immersion is greater than 0.30 MPa. It can be seen from the standard that the strength of water-resistant putty is higher than that of ordinary interior wall putty, so the use of water-resistant putty is not easy to produce empty drums and fall off.
5) High unit price and low comprehensive cost
The water-resistant putty unit price is 1-2 times that of ordinary ones, which is also a factor affecting the promotion of water-resistant putty, but the decorative effect after water-resistant putty is far from the ordinary putty. Moreover, the comprehensive use of the amount of paint and the cost of the putty at the time of the second renovation, and the construction cost, the cost of using the water-resistant putty is low.
