• Tile Bonding Mortar: Ensures strong adhesion of tiles to surfaces, preventing detachment and cracking.
• Tile Joint Filling: Enhances the durability and water resistance of tile joints, extending the lifespan of the installation.

Quality Check Methods for Redispersible Powder

Ensuring the quality of RDP is essential for its effective application. The following methods are commonly used to assess its quality:

Method No. 1: Bonding Ability Check

To check the bonding ability of RDP, a small amount of the solution is poured onto a clean tile surface. After drying, a film of VAE (Vinyl Acetate-Ethylene) should remain on the surface. If the film is hard to scrape off, it indicates a high-quality RDP. This test ensures that the polymer effectively penetrates and adheres to the tile surface.

Method No. 2: Film and Dispersibility Check

This method involves creating a small amount of RDP solution and pouring it into a glass dish. After drying, a smooth and even film should form. The film should be elastic and stretchable when torn off, indicating good dispersibility and quality. This test is crucial for ensuring that RDP can be easily redispersed in water, maintaining its performance properties.

Free Samples and Testing

Before placing a bulk order, it is recommended to test the quality of RDP through free samples. The manufacturer provides free samples with the buyer covering the air shipping cost. This allows customers to evaluate the product's performance and quality stability across different batches.
