Improving Tile Adhesion with Redispersible Polymer Powder

Improving Tile Adhesion with Redispersible Polymer Powder

The tiling process has been around for centuries, and it has served us well. But as technology evolves, so too must our methods of tiling. Traditional tiling methods can be limited in terms of adhesion strength, shrinkage resistance, and water absorption—but that doesn’t mean those shortcomings can’t be overcome. In fact, redispersible polymer powder (RPP/RDP/RDP) is the perfect way to improve the physical and mechanical properties of cementitious tile adhesive (CTA). Read on to learn more about how RPP/RDP blends with other cementitious components to create a superior CTA.

The Role of Redispersible Polymer Powders in Cement-Based and Gypsum-Based Dry Powder Materials

Whether you’re a contractor, engineer, or a DIY enthusiast, you need to know about Redispersible Polymer Powder (or RDP/RPP), which is one of the most important binders used in cement-based and gypsum-based dry powder materials. This type of powder is created by spray-drying polymer emulsions and has the same properties as the original emulsion—namely; it forms a film after water evaporation that is known for its toughness, weather resistance, and adhesion to a substrate. Let’s take a closer look at how this key ingredient helps make mortar waterproof.
