Waterproof Coatings for Roofing, Basements, Bathrooms and Concrete Structures
We manufacture waterproof coatings for different building surfaces and construction conditions. Our range includes polyurethane, polymer cement, acrylic, rubber bitumen, cementitious crystalline and fiber-reinforced coatings, with single-component and two-component formulations, water-based and solvent-based options, and hot-applied and cold-applied products.
These materials serve different purposes, from flexible waterproof films for roofs and wet areas to cement-based protection for concrete and bituminous coatings for underground structures and membrane systems. We supply products for wholesale, import and OEM orders, with formulation and packaging options available for selected product lines.

3. Applications and Product Selection
Roofing and Exterior Surfaces
Our decorative acrylic coatings are available for exposed roofs and exterior walls. Standard colors include white, gray, brick red and sky blue. Customers can select matte or semi-gloss finishes, with heat-reflective components available as a formulation option.
For roof surfaces exposed to mechanical stress, our fiber-reinforced coatings use polyester or glass fibers to improve resistance to tearing and puncture.
Bathrooms and Wet Areas
Water-based polyurethane and polymer cement coatings are available for bathrooms, kitchens, balconies and other wet areas.
Our polymer cement system combines polymer emulsion with cement and mineral powder. Type I has higher elongation, while Type II has higher tensile strength. The coating can be applied by brush, roller or trowel to damp substrates without standing water.
Basements and Underground Structures
Our rubber bitumen and tanking products cover different underground waterproofing requirements. Non-curing rubber bitumen is hot-applied at 150–160°C and can serve as an adhesive and sealing layer in composite membrane systems. Cold-applied rubber bitumen provides an ambient-temperature application option, with standard and high-elasticity formulations and polyester fabric reinforcement available.
Our high-viscosity anti-slip coating is designed for vertical surfaces where non-sagging properties are required. It can also serve as an adhesive layer beneath waterproof membranes. Tanking coatings are available for basement floors, walls and other underground structures subject to positive or negative water pressure.
Concrete Structures and Water Tanks
Cementitious crystalline coatings use active ingredients that react within concrete pores and capillary structures. Our elastomeric cementitious coatings provide a flexible cement-based option for concrete and masonry surfaces. These coatings can be applied to damp substrates without standing water and are not intended for prolonged direct UV exposure.
Steel Roofs and Metal Structures
Our steel structure waterproof coating is a single-component, water-based acrylic formulation for metal roofs and steel structures. We can adjust its formulation for different corrosion environments, including coastal and industrial conditions, with attention to salt spray and acid/alkali resistance.
4. Customization, Packaging and OEM Options
We provide formulation adjustments for selected product lines rather than applying one customization program across the entire range.
| Product | Available Customization |
|---|---|
| Two-Component Polyurethane | Tensile strength, elongation, low-temperature flexibility, curing speed and viscosity |
| Decorative Acrylic Coating | Custom colors and color-code matching, matte or semi-gloss finishes, and heat-reflective components |
| Steel Structure Waterproof Coating | Formulation adjustments for salt spray resistance and acid/alkali exposure |
| Fiber-Reinforced Coating | Polyester or glass fiber reinforcement |
| Cold-Applied Rubber Bitumen | Standard or high-elasticity formulation; polyester fabric reinforcement |
| Polymer-Modified Bitumen | Water-based or solvent-based formulation; SBS, SBR or rubber modification |
For two-component polyurethane, we offer 20 kg, 50 kg and 200 kg packaging, neutral packaging, OEM labels and transportation markings. Sample development takes approximately one week.
Decorative acrylic coatings are available in 5 kg, 20 kg and 50 kg packaging. Customers can select standard colors—white, gray, brick red and sky blue—or request color-code matching. Custom labels and transportation marks are also available. EXW, FOB and DDP delivery terms are available for this product.
Minimum order quantities vary by product: 1 ton for several standard formulations, 1 ton per model for two-component polyurethane, and 1 ton per color for decorative acrylic coatings.
