Frequently Asked Questions
What do masonry primers and prep products do?
They give repair compounds, adhesives, membranes, sealants, and coatings a clean, stable surface to stick to. Choose a primer based on your substrate, its moisture, and the product that goes on top. Not every surface needs one, and some systems need a specific type.
Which primers work on damp masonry or green concrete?
Gripset E-60, Gripset Xpress H2O Plus, and Megapoxy 154 handle moisture on damp masonry, brickwork, mineral substrates, and green concrete. Check the moisture level, substrate limits, coat build, cure time, and what you can apply over them first.
Do I need primer on every masonry surface?
No. Some surfaces need it, some do not, and some systems call for a specific prep method. Absorption and surface condition vary. Clean and check the surface, then follow the product instructions to see if priming is required.
What is the difference between porous and non-porous primers?
Porous primers like Everflex Supaprime and Gripset GP penetrate or stabilise absorbent surfaces such as brick and render. Bond-bridge products like Eco Prim Grip, Gripset OP, and Gripset Xpress SP help later materials grip dense or smooth surfaces. Match the primer to your substrate.
Can I put any primer under any masonry product?
No. The primer must work with the surface below and the product above it. A sealant primer, moisture barrier, membrane primer, and bond bridge each do different jobs. Read the product instructions for your next layer and use only a primer the system allows.
What is a bond bridge and when do I need one?
A bond bridge helps a later product grip a dense or smooth surface that stays too slick to bond. Use it on non-porous substrates or dense concrete where a porous primer will not penetrate. Check the product instructions to confirm it suits your system.
