Choosing the right waterproof coating starts with the application area. Roofs face rainfall, sunlight and temperature changes, bathrooms require continuous moisture protection, while exterior walls need resistance to rain penetration and long-term weather exposure. Using one waterproofing product for every surface can increase the risk of adhesion failure or premature deterioration.
Caruns manufactures a complete waterproofing range including K11 Waterproof Mortar, JS Polymer Waterproof Coating, Red Rubber Roof Waterproofing, Acrylic Heat-Reflective Waterproof Coating, Transparent Waterproof Adhesive and Liquid Waterproof Membrane. These products are designed for roofs, bathrooms, basements and exterior protection.
| Area | Main Selection Requirement |
|---|---|
| Roof | Weather resistance and water protection |
| Bathroom | Continuous waterproof layer and adhesion |
| Exterior wall | Rain resistance and substrate compatibility |
| Basement | Moisture penetration resistance |
| Renovation | Compatibility with existing surfaces |
A roof exposed to strong sunlight requires different performance from a bathroom protected by tiles. Exterior walls also need compatible primers and finishing coatings to create a complete protective system.
For project sourcing, direct manufacturer cooperation provides better control over formulation, raw materials, testing and production records. A trader normally depends on another factory for technical adjustment, which can make project-specific development more difficult.
Caruns operates a 16,000 square meter manufacturing base with annual capacity above 20,000 tons and more than 500 coating formulations, according to company manufacturing records.
Our customized waterproof coating process can include:
Substrate analysis
Water exposure evaluation
Climate assessment
Formula selection or adjustment
Sample testing
Packaging customization
Trial production
Mass production
Caruns provides OEM and ODM solutions according to different climatic conditions and environmental compliance requirements.
Incoming materials are tested for solid content, viscosity, pH, fineness, moisture and environmental indicators. During production, batching, dispersion and formulation stability are monitored. Finished products are checked for adhesion, water resistance, uniformity and batch stability.
Quality management follows IQC, IPQC, FQC and OQC, covering incoming materials, production processes, finished products and outgoing shipments.
Before placing a bulk order, confirm substrate type, waterproofing location, expected water exposure, climate, application method, required quantity, packaging, production lead time and technical documents.
For international supply, Caruns supports compliance credentials including ISO9001, ISO14001, ISO45001, CE, RoHS, REACH, French A+ and German AgBB.
The right waterproof coating should therefore be selected according to the specific application environment, complete coating system, manufacturing consistency and verified quality control, rather than relying on one universal product for every construction area.
