Resin Bound Primer – PermaPrime

PermaPrime, the resin bound gravel primer is a technologically advanced solution designed specifically to improve adhesion between porous surfaces such as concrete or tarmac and mixed resin bound gravel material. Its cutting-edge formulation, featuring a high-performance moisture-curing urethane prepolymer, ensures exceptional adhesion between the resin and the substrate below. Applied prior to laying your resin bound material, this quick-drying coating system creates a barrier between the stone mixture and below surface allowing greater adhesion between the two whilst also preventing porous bases from absorbing resin from the material and weakening the final surface.

Preparation is a vital part of using our resin bound gravel primer, before applying any primer you must prepare the substrate adequately. The surface needs to be sound, clean, dry and free from any oil or grease whilst any cracks or defects in the substrate should be repaired before application. Without the correct prior work, the primer may not perform to its fullest capabilities and there may be poor adhesion between your new resin gravel surface and the existing sub-surface.

We recommend applying PremaPrime straight from the can with a brush or roller. One application will normally suffice but in some cases, highly porous substrates may require two coats. You should expect to achieve 30-50m² per 5 litre can of Primer depending on the concrete.

For safe storage, handling & personal protection whilst using the PermaPrime, recommendations in the Safety Data Sheet must be followed at all times.
