Floor Primer

Floor tile primer is a rapid-drying acrylic primer suitable for priming floors prior to the fixing of ceramics, mosaics and natural stone tiles in both internal and external wet or dry environments. It works to enhance adhesion through the consolidation of the substrate surface, and also reduces absorbency allowing materials to flow, cure and bond successfully. The primer can be easily applied with a brush, a roll or a spray.

What does a floor primer do?

A floor primer is a preparatory coating applied to a substrate before the application of another flooring material, such as a self-leveling compound, adhesives, or paints.

Do I need primer on floor?

The need for a primer on the floor depends on various factors, including the type of flooring material you are installing and the condition of the substrate. While it's not always mandatory to use a primer, there are situations where using a primer is highly recommended to achieve optimal results. Here are a few scenarios where using a floor primer is typically advisable:

  1. Porous Substrates: If your floor substrate, such as concrete or wood, is porous and has a high absorption rate, using a primer is beneficial. Primers help seal the pores, create a more uniform surface, and prevent excessive absorption of moisture from subsequent flooring materials. This improves the adhesion and overall performance of the flooring system.
  2. Smooth Substrates: In some cases, particularly with smooth or non-porous substrates like existing tiles or certain types of coatings, using a primer can enhance the bonding between the substrate and the new flooring material. The primer creates a more receptive surface, allowing for better adhesion and reducing the risk of delamination.
  3. Moisture Control: If moisture is a concern in your project, using a moisture-blocking primer is recommended. Moisture-resistant primers act as a barrier, preventing moisture vapor transmission from the substrate to the flooring material. This is particularly important when installing moisture-sensitive flooring materials like hardwood, as excess moisture can cause damage.
  4. Substrate Preparation: Applying a primer can improve the overall substrate condition, especially if it's weak, damaged, or has dusting issues. Primers can stabilize and strengthen the substrate, reduce dusting, and create a more suitable surface for subsequent flooring materials.
