• Wall Putty: Improves the adhesion and durability of wall coatings.
• EIFS Mortar: Provides excellent adhesion and flexibility for exterior insulation systems.
• Interior Wall Mortar: Ensures a smooth, crack-free finish for interior walls.
• Tile Bonding Mortar: Increases the bond strength between tiles and substrates.
• Tile Seam Filling: Offers excellent filling properties and resistance to cracking.

Quality Assurance and Testing

Ensuring the quality of RDP is crucial for its performance. The following methods are commonly used to assess its quality:

Method No. 1: Bonding Ability Check

1. Prepare a small amount of RDP solution.

2. Pour the solution onto a clean tile surface.

3. Allow it to dry completely.

4. A VAE film should form on the surface. If it is difficult to scrape off, the product is qualified.

Method No. 2: Film Formation and Dispersibility Check

1. Prepare a small amount of RDP solution.

2. Pour the solution into a glass container111 and let it dry.

3. A smooth, even film should form. When torn off and stretched, the film should be elastic and tensile.

For a visual demonstration of these tests, watch the quality check video.
