How to check for curing compounds or other contaminations on your concrete substrate

Checking for curing compounds or other contaminations on concrete substrates

This is what you should consider

To ensure an excellent bond is achieved to a concrete substrate, Waterproofing and Tiling end-users should always check for curing compounds or other contaminations by:

  1. Taking a bottle of water and placing droplets of liquid randomly over slab.
  2. Revisit the area after 10 or 15 minutes to see whether any water has been absorbed into the concrete.
  3. If the water has not been absorbed then the floor has to be mechanically prepared. For example, the concrete should be ground using an electric grinder with a diamond disc to remove any contamination.
  4. This preparation will provide you with a good bond to the substrate.
