Tiles are one of the most common floor coverings in German households. If you want to refine a room with the beautiful floor covering the right tools and high-quality materials are essential. This also includes the right primer for tiling. Tile adhesives as the sole bonding layer to the substrate is often not enough. To be sure that the right primer has been selected it is important to check the substrate thoroughly.

In our brochure PCI Tiling and Natural Stone Technology, our team of experts gives you valuable tips and product recommendations for testing and preparing the substrate.

Types of primers for tiling and their function

A primer is an important part of laying tiles and natural stone for

  • the protection of the ground
  • as a bonding agent
  • improving the substrate strength and
  • for shutting off the substrate moisture.

In general, a distinction can be made between dispersion primers and synthetic resin primers. The former, like PCI Gisogrund®, are mostly polymers or synthetic resins dissolved in water. To achieve the desired effect, too much dilution or too little amount applied must be avoided. Synthetic resin primers for tiling, on the other hand, are based on epoxy resins or polyurethanes. They effectively stop moisture penetration and are often used as a capillary barrier.

During the priming process, be sure to ensure a homogeneous result. Puddles and differently structured sections prevent homogeneous drying which can result in poor adhesion quality and hollow spaces in the floor covering.
