Compared to regular putty, water-resistant putty offers several advantages beyond its excellent moisture resistance. Here are some key features that make it a superior choice for interior wall applications:
1) Smooth and Soft Finish
Water-resistant putty provides a white, smooth, and delicate surface after application. When treated with light, the texture becomes even more refined, offering a soft touch that can serve as a decorative layer on its own. This makes it ideal for achieving a high-quality finish without additional coatings.
2) Long-Lasting Durability
Unlike traditional putty, which often needs to be removed and reapplied during future renovations, water-resistant putty remains stable over time. It doesn’t require removal during second or third decorations, saving both time and effort. This also reduces waste, minimizes environmental impact, and protects the structural integrity of walls. With proper application, water-resistant putty can last as long as the wall itself.
3) Reduced Paint Consumption
The high density and bright whiteness of water-resistant putty improve paint adhesion and coverage. As a result, it can reduce paint usage by up to 25–30% per square meter compared to regular putty. This not only lowers material costs but also enhances the overall efficiency of the painting process.
4) Strong Adhesion
According to the JG/T298-2010 standard for building interior putty, water-resistant putty must meet higher performance criteria. While ordinary putty has a minimum bond strength of 0.25 MPa in dry conditions, water-resistant putty achieves at least 0.50 MPa. Even after immersion, it maintains a bond strength above 0.30 MPa. This ensures better adhesion, reducing the risk of peeling or blistering over time.
5) Higher Initial Cost, Lower Overall Cost
Although water-resistant putty typically costs 1–2 times more than regular putty, its long-term benefits make it a cost-effective option. The improved finish, reduced paint usage, and lower renovation costs over multiple cycles lead to a significantly lower total cost. In the long run, using water-resistant putty is a smarter investment for both aesthetics and durability.
Sandwich Panel
What are the methods for judging the pros and cons of sandwich panel?
The material of the sandwich panel directly affects the later use. Sandwich panels are the main building materials for Prefabricated House and Steel Structure Warehouse. If you want to choose high-quality panels, you must have an understanding of their basic quality. There are many types of boards on the market, and their core materials, steel plates, adhesives, etc. are different, and the quality will also be affected. So how to judge its pros and cons?
check edge
Because the sandwich panel has several layers, it is difficult to judge its internal quality from the surface. Therefore, it is still necessary to observe its exposed edges first, and it is necessary to pay attention to whether its cross-section is clean and ensure that it is tight. If there are problems such as graying and impurities, then there must be problems in quality, so it is still necessary to do a good job of cross-sectional inspection.
Tap to hear the sound
If it is a relatively good board, you can simply tap it with your fingers. If the sound is a crisp metallic sound, then it is a relatively good board. The fire rating of the Rock Wool Sandwich Panel is Class A, and the fire rating of the polyurethane sandwich panel and Eps Sandwich Panel is B1.
Note the thickness
The thickness of the sandwich panel directly affects the long-term use in the later period. It is necessary to observe the substrate, peritoneum, etc., especially the thickness and quality of the coating, which we cannot ignore. It is necessary to choose a plate with a relatively thick coating and guaranteed quality. Generally, the thickness of the substrate should be about 0.4-0.8MM. If you see the real thing, you should also measure it. The thickness of the finished product is 50mm, 75mm, 100mm, 150mm. The bulk density of the core material is also an important link that affects the quality.
certificate
In fact, as long as it can cooperate with regular manufacturers, the plates sold by the manufacturers need to go through various inspections, and the quality must meet the regulations. Therefore, when purchasing, you can directly check whether it has a certificate of conformity. If you choose a plate from a regular manufacturer, you can not only enjoy a preferential price for direct sales from the manufacturer, but also enjoy good after-sales service.
Now there are many manufacturers supplying plates, and the market quotations and quality of each manufacturer are also different, so it is still necessary to do a good job of quality comparison and price measurement. It is suggested that when purchasing sandwich panels, one must pay attention to its specific quality, and compare the quality of the actual products in order to select high-quality panels.
