FAQ’s

Frequently Asked Questions

Clear, honest answers about how our Product.

Where is polymer cement waterproofing commonly used?
Polymer cement waterproofing is well suited to concealed or non-exposed applications such as retaining walls, basements and other concrete waterproofing areas. It is commonly selected where the waterproofing layer will subsequently be covered or protected rather than left permanently exposed.
What application method gives the best result for polymer cement waterproofing?
For demanding waterproofing areas, a reinforced system using one layer of fabric with three coating applications can provide the best overall result. The reinforcing fabric improves continuity and crack resistance, while the multiple coating layers help achieve a uniform waterproofing membrane.
Is polymer cement waterproofing suitable for permanent water immersion?
The standard version is not recommended for long-term continuous water immersion because prolonged immersion may cause discoloration or peeling. If your project requires a version specifically designed for permanent water immersion, please contact our team for a customized product recommendation.
What is the shelf life and recommended storage condition?
The product should be stored sealed in a cool, ventilated place at 5°C–30°C and protected from direct sunlight. Under proper storage conditions, the typical shelf life is 6 months. The product should be used within the stated shelf life and the packaging should remain intact before use.
What substrate preparation is required before application?
The substrate should be thoroughly cleaned and should be firm and free from dust, loose particles, oil and other contaminants. Cracks, corners and penetrations should be treated before the main coating application to help form a continuous waterproofing layer.
