Hollow tiles or tiles falling off the wall are common quality problems in construction. These issues are not just ugly—they can also be dangerous. Most of these problems happen because traditional cement mortar is too brittle and does not stick well enough to modern, smooth tiles.
To solve these problems from the root, RDP (Redispersible Polymer Powder) is the essential additive for modern tile adhesives.
Traditional cement is stiff. When temperatures change or a building vibrates slightly, the stiff mortar cracks, causing the tiles to come loose.
The RDP Solution: RDP forms a flexible polymer film inside the mortar. This film acts like a "cushion" that absorbs stress and prevents cracks. This ensures the tile system stays stable even when the wall moves slightly.
Many modern tiles (like vitrified tiles) have very smooth surfaces that are hard to grip.
The RDP Solution: RDP creates a double bonding effect. It uses "mechanical locking" to stick to the wall and "physical suction" to grip the smooth back of the tile. This ensures a permanent bond, even on the most challenging surfaces.
Construction quality often depends on how easy the material is to use.
Longer Open Time: RDP helps the adhesive stay wet for a longer time. This gives workers more time to place and adjust tiles correctly.
Anti-Sagging: It stops heavy tiles from sliding down vertical walls.
Easy to Spread: It makes the mortar smoother, ensuring that 100% of the area behind the tile is covered with adhesive.
Thanks to RDP, the industry is moving from the old "thick-bed method" to the modern "thin-bed method." This new way uses less material, saves space, and provides a much more reliable bond. It is the global standard for high-quality decorative engineering.
Using RDP is the most effective way to prevent tile hollowing and falling off. By upgrading your formula with RDP, you can ensure a professional finish that is durable, safe, and long-lasting.
