Many harbor this notion during home renovations: "Thicker waterproofing must equate to better protection." But is that really the case?

The Myth of Thickness

No, thicker isn't necessarily better. For one, waterproofing should be applied in multiple thin layers, not too thickly, to avoid cracking or peeling—similar to applying makeup. Moreover, like cosmetics, waterproofing materials aren't cheap. Over-application is not only time-consuming and labor-intensive, but also wasteful. However, too thin a layer won’t be effective and can age and fail prematurely.

The Optimal Thickness

So, what's the right thickness? Taking Polyaspartic Polyurea as an example for non-destructive waterproofing:

• Bathrooms and Kitchens: Suggested thickness is 0.3-0.4mm for flat surfaces, 0.15mm for vertical surfaces.
• Balconies: Suggested thickness is 0.4-0.6mm.
• Exterior Walls: Suggested thickness is 0.4-0.6mm.
• For prone areas like drains and pipes: Multiple coats (4-7 layers) are recommended.

Different products have different requirements, understanding them before commencing work is crucial. Remember, actual usage depends on various factors such as construction technique, surface smoothness, environmental temperature, and product consistency.

Effective Waterproofing Application

During application, avoid trying to achieve the required thickness in one go. Instead, apply multiple thin coats, crisscrossing each layer to prevent missed spots and bubbling.

A Special Note: Before the waterproofing layer has set, avoid walking on it to prevent damage. Protect entrances, walls, and other areas during the process to avoid contamination of the finished surfaces.

In conclusion, different waterproofing materials require different thicknesses depending on the application. Don't fall into the trap of thinking thicker is always better—it could lead to wasted expenses and ineffective results. Hopefully, this insight has been helpful.

Polyaspartic Polyurea's advantages extend beyond waterproofing to anti-corrosion and flooring projects, offering superior performance in diverse applications.

Shenzhen Feiyang Protech Corp., Ltd. specializes in researching and producing polyaspartic polyurea resin and other new chemical products. We are recognized as a "National Special New Key Little Giant" and a "State-level High-tech Enterprise", with more than 50 polyaspartic polyurea invention patents. We also participated in the preparation of 13 industry standards for polyaspartic polyurea materials as a leading company in this field, ranking No.1 in the Chinese market.

In the coating industry, polyaspartic polyurea is used in construction machinery, automobile, containers, fan blades, marine heavy corrosion protection, and high-end industrial and commercial floor coatings. In the adhesive field, it is mainly used in sealants, stone adhesives, electronic adhesives, film circuit packaging adhesives, and other high-end applications. In the waterproofing materials sector, it is primarily used in hydroelectric dams, water parks, building waterproofing repair materials, and other areas. In the structural materials field, it is applied to curling tracks, artificial ice skating rinks, and other structural materials.

Polyaspartic polyurea is considered a high-end new material in the strategy of manufacturing power. We have broken the foreign technology monopoly and filled the domestic market gap. Due to its comprehensive characteristics of "Environmental protection, Energy saving, and Long durability", polyaspartic polyurea can contribute to the realization of genuine carbon neutrality in the coatings, adhesives, and materials industries.

Since 2012, Feiyang polyaspartic ester resin has been supplied overseas. It has been widely used to replace Bayer's current polyaspartic system in many coating companies and has been applied in anti-corrosion and waterproofing by international coating companies.
