Frequently Asked Questions
What is a non-porous substrate primer?
Non-porous substrate primers create a bond on smooth surfaces that do not absorb liquid, such as glass, metal, PVC, polished concrete, and existing tiles. They work by chemical activation, textured mechanical key, or solvent etching rather than penetration.
Do I need to grind existing tiles before tiling over them?
No. Mapei Eco Prim Grip creates a textured mechanical key with embedded silica sand on existing tiles and smooth surfaces. It removes the need for mechanical grinding. Apply it neat by brush or roller and wait 15 to 30 minutes.
Can I use a non-porous primer on glass?
Yes. Adheseal Primer 50A bonds to glass, porcelain, metals, plastics, and rubber with a wipe-on cloth application. It dries in 15 seconds. Do not use it on lead or copper. The Autoshield Activator is for glass and lacquer surfaces only.
How do I know if the non-porous primer has covered the surface?
Gripset OP Primer dries blue so you can see full coverage at a glance. This visual indicator helps confirm no gaps before applying the membrane. Most other non-porous primers dry clear or translucent. Check the product data sheet for specific drying cues.
Which non-porous primer has the lowest VOC?
Gripset Xpress SP Primer has nil VOC and suits self-adhesive sheet and liquid membranes. Mapei Eco Prim Grip carries the EC1 Plus low VOC rating. Both are water-based products applied neat. Most solvent-based non-porous primers have higher VOC levels.
