Resin Flooring Primers

Resin flooring primers are specialist preparation coatings designed to ensure optimal adhesion and long-term performance of resin floor systems. Applied as the first layer, primers penetrate and seal the substrate, creating a stable, uniform base that enhances bonding and reduces the risk of defects.

Formulated for compatibility with epoxy, polyurethane, and polyaspartic systems, resin flooring primers improve durability, control surface porosity, and support a smooth, high-quality finish. They are an essential component in achieving reliable, professional resin flooring installations.

Which primer for which substrate

Every Jofa floor starts with a primer, and the right one depends on the concrete underneath: sound and dry, damp, oil-contaminated, weak and porous, or about to take a screed or an ESD system.

EPR-100 Solvent Free Epoxy Primer: the general-purpose primer for sound concrete. It penetrates and seals porous substrates, and can be filled with quartz for a scratch coat.
SRS-700 Deep Penetrating Epoxy Primer: ultra-low viscosity, for strengthening weak and porous concrete and cutting outgassing and pinholing.
DPM-230 Moisture Tolerant Epoxy Primer: a primer that also works as a damp proof membrane, tolerating concrete at up to 98% RH.
DPM-250 Flexible Epoxy Damp Proof Membrane: a flexible membrane for residual moisture and rising damp, up to 98% RH, that accommodates minor substrate movement.
OT-235 Oil Tolerant Epoxy Primer: for oil-contaminated substrates, typically in refurbishment work. It cures even at low temperatures.
EPT-115 Epoxy Tack Coat Primer: a bonding coat for resin screeds and covings, applied wet-on-wet and ready to overlay in 1 to 2 hours.
Bondex-421 Waterbased Epoxy Bonding Primer: a fast-curing, low-odour bonding primer with a long pot life, suitable for occupied areas.
WB-120 ESD Water-based Conductive Primer: the conductive layer for static-control (ESD) floors.

Primer questions

Which primer should I use on damp concrete?

Use DPM-230 or DPM-250. Both tolerate concrete at up to 98% relative humidity and act as a damp proof membrane. DPM-250 is flexible and accommodates minor movement in the substrate.

Can I prime concrete contaminated with oil?

OT-235 is made for oil-contaminated substrates. The surface still needs preparing first, and our technical team can advise on how for your floor.

Which primer goes under a polyurethane cement floor?

Use JofaCrete Primer, which is compatible with every JofaCrete product and system and works as both primer and sealer.

The product datasheets are in the datasheet library. Work out how many kits you need with the coverage calculator, or request a specification and our technical team will recommend a system.
