Rayson PrimeBond E20
Rayson PrimeBond E20 is a two-component, medium-viscosity, solvent-free epoxy bonding primer that anchors resin floor systems to concrete, screed, asphalt and prepared metal — on dry or damp substrates.
ConcreteCement screed TDS RY-TDS-101
Best for
Best for priming concrete and cementitious screeds before Rayson epoxy and polyurethane floor systems, including slabs that cannot be fully dried out.
PrimeBond E20 is the workhorse primer of the Rayson range. A medium-viscosity, solvent-free two-component epoxy, it penetrates mechanically prepared substrates and forms the adhesion bridge that the rest of the floor system depends on. In pull-off testing on properly prepared concrete, bond strength exceeds the cohesive strength of the concrete itself — failure occurs in the substrate, not the primer.
The formulation tolerates damp (though not wet) surfaces, which matters on ground-bearing slabs and in tropical conditions where full drying is rarely practical. It also handles new concrete, existing epoxy floors, cementitious screeds, asphalt and mechanically prepared metal, making it the default first coat across most Rayson floor build-ups.
Because it is solvent-free, PrimeBond E20 is suitable for use in enclosed and poorly ventilated areas — basements, plant rooms and occupied buildings — where solvent-based primers would be ruled out.

Quoted after inspection The practical details
Rayson PrimeBond E20: questions people ask
Can PrimeBond E20 be applied to damp concrete?
Yes — it is formulated for dry or damp substrates, provided there is no standing water and substrate moisture does not exceed 5%. For slabs above that, or with active moisture ingress, speak to our technical team before specifying.
Do I always need a primer under a Rayson floor coating?
In almost all cases, yes. The primer seals porosity, prevents pinholing in the body coat and provides the adhesion the whole system relies on. Skipping it is the most common cause of coating failure.
How soon can the next coat go on?
The primer must be firm enough to walk on but still within its overcoat window. Confirm exact recoat times with our technical team for your programme.
Is it safe to use in enclosed spaces?
PrimeBond E20 is solvent-free and stated as suitable for unventilated areas. Standard PPE and good working practice still apply; consult the SDS once available.
What surface preparation is required?
Mechanical preparation — captive shot blasting, milling or diamond grinding — to a sound, open, dust-free surface. Weak concrete must be removed, defects filled, and all dust vacuumed off before priming.
Can it go over an old epoxy floor?
Yes, provided the existing coating is sound and well bonded. Abrade the surface, clean thoroughly and carry out an adhesion trial first.
