Dongshun Super Elastic & Flexible Waterproof Coating

Super Elastic & Flexible Waterproof Coating

Cement-Based Polymer Waterproof Coating for Concrete & Mortar

This cement-based polymer waterproof coating is designed for waterproofing concrete, mortar, and masonry structures. Ideal for absorptive surfaces in bathrooms (floors/walls), kitchens, balconies, and other wet areas requiring high elasticity and crack resistance.

Key Advantages

1.Eco-Friendly & Non-Toxic – Water-based, low VOC formula safe for indoor use.

2.Super Elastic Film – Exceptional crack resistance and flexibility for dynamic substrates.

3.Superior Waterproofing – High impermeability, alkali resistance, and water tolerance.

4.Breathable Design – Allows vapor transmission to prevent blistering while blocking water.

5.Fast Curing – Ready for next coat in 3–4 hours, reducing project downtime.

6.Easy Application – Simple mixing and brush/roller application on damp surfaces.

Application Guide

1. Substrate Preparation

Ensure substrates are solid, smooth, clean, and free of dust, oil, and loose debris.

Pre-wet substrates to maintain moisture (no standing water). Round internal/external corners for optimal coverage.bstrate Preparation

Ensure substrates are solid, smooth, clean, and free of dust, oil, and loose particles.

Pre-wet substrates thoroughly to maintain moisture, but no standing water is allowed.

2. Mixing

Follow package-labeled ratios for liquid and powder components.

Add liquid component to a mixing bucket first, then slowly pour in powder while stirring continuously for at least 5 minutes until lump-free.

Stir intermittently during use; use mixed slurry within 2–4 hours.

3.Application

Apply 2–3 coats with a brush or roller:

1st coat: Allow 3 hours to dry before applying 2nd coat (brush perpendicular to the first).

2nd coat: Allow 4 hours to dry before applying 3rd coat (brush perpendicular to the second).

Apply extra coats to corners, pipe roots, and joints.

Final cure time: 24 hours for full dryness.

4. Coverage

3–4kg/m² (for 1–2mm film thickness, varies by substrate smoothness).

5. Application Conditions

Apply at 5–35°C and <85% relative humidity.

6. Tool Cleaning

Clean tools immediately with water after use.

7.Curing Tips

Moisture Return Warning: Temporary moisture spots may appear in humid areas (e.g., basements) but will disappear after 10–15 days of curing.

Enhance curing by mist-spraying or covering with a damp cloth during days 1–3.

Storage

Store at 5–35°C in a cool, dry, clean place. Keep containers tightly sealed to prevent contamination.

Shelf life: Over 12 months when unopened and properly stored.
