How to choose waterproof coating?
Three practical purchasing tips
- Look at the certifications and look for environmental protection and performance standards
Priority is given to products that have passed China’s ten-ring certification, French A+, German TÜV or GB/T 23445-2009 (national standard for polymer cement waterproof coatings).
Environmental protection is the bottom line, and performance is the guarantee. - Match type according to scene
- Kitchen, bathroom, balcony: choose JS or K11 cement-based paint with good flexibility and water pressure resistance;
- Roofing and basement: polyurethane or high-elastic acrylic is recommended, which is more resistant to cracks and punctures;
- Children’s room, elderly room: Be sure to pay attention to VOC content and odor, and prefer clean-odor products.
- Don’t just look at the unit price, consider the comprehensive cost
Low-price paint may require 3 coats to reach the standard, while high-quality brands usually need 2 coats and have a lifespan of more than 10 years.
Including labor and rework costs, choosing the right one the first time will actually save money.
Things you need to know about waterproofing projects
1. Waterproofing is not about “the thicker the paint, the better”
Many people think that it is safer to paint more than once. In fact, over-painting will cause the coating to crack and peel.
National standards stipulate that the single film thickness of polymer cement waterproof coating (JS) should be 0.5mm, and the total thickness is usually 1.5 – 2.0mm.
Excessive thickness will cause stress cracks due to different drying speeds inside and outside.
2. Treatment of the base layer before waterproofing is more important than the coating itself
90% of waterproofing failures result from the base layer not being properly treated!
The wall surface must be solid, free of floating dust, open water, and hollows.
Before construction, holes should be repaired with a leak-proof sealant, and the inner corners should be made into “arc corners” (R corners) to avoid stress concentration at right angles that may lead to cracking.
3. Waterproof paint cannot be applied directly to the insulation layer or lightweight partition wall.
For example, base surfaces with strong water absorption or low strength such as foam concrete, gypsum board, calcium silicate board, etc. must first undergo interface treatment (such as painting wall solids or special primer), otherwise the waterproof layer will easily fall off.
Tips: Waterproofing is a “one-time project” and the cost of repair is extremely high.
Instead of saving hundreds of dollars to buy inferior materials, it is better to choose a big brand and standardize the construction in one step.
After all, quality is best seen where you can’t see it.
Conclusion: Waterproofing is no small matter, brand is the guarantee
Waterproofing project is a “hidden project”. Once something goes wrong, the repair cost will be high and life will be affected.
Rather than fixing the problem afterwards, it is better to do it in one step.
This list of the top ten brands of waterproof coatings in 2026 covers not only technology leaders such as Oriental Yuhong, Keshun, and Sika, but also cutting-edge forces close to home users such as Sankeshu and Wodelali. Whether you are decorating your own home or purchasing an engineering project, you can find a suitable choice.
True waterproofing is not about “just applying one layer”, but the double guarantee of “choosing the right brand + standardizing the construction”.
I hope this list can help you avoid pitfalls and spend every rainy season with peace of mind!
