What should you check first?

Tell whether the concrete is new or finished earlier. Remains of other treatments, paint or contamination can affect the adhesion. Have the condition checked instead of immediately applying a product over the entire surface.

How does this affect your choice?

The necessary pre-treatment depends on the material and the plaster system. A product for controlling suction is not automatically the same solution as a means to improve adhesion on smooth concrete. Use the current product information and the evaluation of the performer.

Planning the next step

Ask when the next layer can be applied and how the surface will remain clean in the meantime. Take seams, repairs and edges with you in preparation. Capture the products used so that the surface of the plaster layers can be traced later.

Practical checklist

  • Describe previous treatments
  • Separation suction and adhesion
  • Ask for the waiting period of the product
  • Save system data

Questions about this topic

Is every primer suitable for smooth concrete?

Which agreements help to implement the agreement?

A smooth substrate requires an appropriate adhesion

Concrete must be evaluated for the condition of the surface and the plaster product. Gloss, contamination or residues from previous agents may be relevant. Therefore, choose a product not only because it is concrete.

Discuss these points for your home

  • Have the surface assessed for suitability.
  • Follow preparation and processing as one product system.
  • Report previous layers or treatments as known.
