Rayson MortarBond EM90 is a three-pack, solvent-free epoxy mortar — resin, hardener and graded aggregate — that reinstates concrete floors with a non-shrink, highly abrasion-resistant repair.
MortarBond EM90 rebuilds damaged concrete with epoxy strength. The three components — resin, hardener and graded aggregate — combine into a trowelable mortar that hardens without shrinkage to a compressive strength of 80 N/mm² at 7 days, well above the concrete around it.
The cured mortar is highly durable and tough, with high abrasion resistance, good adhesion and good resistance to chemicals and solvents — so patches, joint arrises and worn areas repaired with EM90 stay put under forklift traffic rather than breaking out again.
It is applied by steel trowel over a compatible epoxy primer and is typically overcoated by the floor system, keeping repairs invisible inside the finished floor.

Quoted after inspectionCompressive strength reaches 80 N/mm² at 7 days — several times stronger than typical floor slab concrete.
No — the epoxy binder hardens without shrinkage, so patches stay tight to their edges instead of debonding.
Yes, a compatible epoxy primer applied to the prepared repair area. Rayson recommends PrimeBond E20, with final system pairing to be confirmed by our technical team.
Indicatively hard dry in 16 hours at 30 °C, with full cure and chemical resistance at 7 days. For heavy loading, confirm timing with our technical team.
Epoxy mortars perform best at a defined minimum thickness with cut edges rather than feathering. Square-cut the repair perimeter for a durable result.
Tell us what the surface is, where it is and what it has to withstand. Rayson replies with a system recommendation; for installation, the applicator for your area in Johor, Kuala Lumpur or Penang is introduced to quote the job.
Malaysia launch: 1 March 2027. Enquiries are welcome now; supply, site assessment and installation timing are confirmed for each project.
