How to find the right Flooring Adhesive Primer AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Flooring Adhesive Primer

System match
Use the primer the adhesive or leveler manufacturer specifies for that product. Warranties and bond performance depend on the matched system.
Porous vs non-porous substrate
Choose the primer rated for your surface: porous concrete and wood, or non-porous surfaces such as existing tile, terrazzo or adhesive residue. Porous-surface primers will not bond to glazed or sealed surfaces.
Dilution and coats
Follow the stated dilution and number of coats for the substrate's porosity. Very absorbent concrete often needs a diluted first coat to stop pinholing.
Drying before covering
Let the primer dry to the film or tack state the instructions specify before applying adhesive or leveler. Covering wet primer traps moisture and weakens the bond.
Moisture first
Test slab moisture before priming. Primer is not a moisture barrier unless it is explicitly rated as one. High slab moisture causes adhesive failure regardless of primer.

Brands that matter

  • Ardex: Offers primers for both porous and non-porous substrates.
  • Mapei: Primers matched to its leveler and adhesive lines.
  • Henry: Primers paired with its DIY levelers and adhesives.
  • Custom Building Products: Primers for the LevelQuik system.

What to avoid

  • Mixing brands between primer and leveler on warranty jobs
  • Priming over dust, curing compounds or loose residue
  • Treating primer as a moisture mitigation system
