Frequently Asked Questions
Why prime before tiling?
Primer prepares porous or non-porous substrates for the next system layer. It can control absorption and improve the bond of the membrane, levelling layer or tile adhesive.
Does every substrate use the same primer?
No. Porous concrete, dense concrete, existing tiles and cured membranes can need different primers. Select only a primer approved for the substrate and following layer.
Can primer replace surface preparation?
No. Primer does not remove dust, grease, weak material or old coatings. Prepare the surface first, then apply primer as the technical data requires. Match the product spec to the job conditions before you start.
Do I prime before waterproofing?
Often, yes. Many under-tile membrane systems require a compatible primer before the membrane. Follow the membrane manufacturer's system instructions. Match the product spec to the job conditions before you start.
Can I tile over primer immediately?
Only after the primer has dried or cured as specified. The next layer must be installed inside the product's stated application window. Match the product spec to the job conditions before you start.
