A pothole, broken joint edge, static crack and moving joint do not receive the same treatment. Rayson reviews the defect, substrate condition and traffic before defining the repair-and-protection route.
First identify whether the damage is a local pothole, spalled joint edge, static crack, moving joint, vertical defect or coating delamination. Only after weak material, moisture and movement risks are understood—and the repair is taken back to sound concrete—can the repair material and protective coating establish a dependable bond.
Each selection changes the site visual, technical priority and project brief carried into your enquiry.
Cut back to a sound, load-bearing edge and reinstate with an epoxy mortar suited to horizontal traffic. Confirm whether the joint itself is still moving.
Weak material, feather edges and trapped dust shorten repair life. Define the pothole or spall cleanly, then prime and reinstate it with the appropriate epoxy mortar.
Record width, direction, change and signs of water. A static repair and a movement problem that needs a flexible joint or engineering review follow different routes.
Equipment bases, kerbs, upstands and local overhead details require a thixotropic non-sag compound checked against the actual depth and substrate condition.
Inspect the interface between coating, primer, surface concrete and moisture. Covering a loose area simply preserves the same weakness below the new system.
Rayson can help define coating and non-structural repair routes. Structural safety and continuing movement require assessment by a suitably qualified engineering professional.
This is the project-review route—not a substitute for site assessment or the product TDS.
Define defect type, cause and extent
Plan traffic, dust and the shutdown zone
Remove to sound concrete and form reliable edges
Mechanically prepare for the selected material
Place the repair for its duty, depth and orientation
Recoat the local area or full floor where required
These are preliminary directions. Confirm the actual defect, substrate, moisture, repair depth, traffic and complete build-up against the relevant TDS.
For horizontal floor spalls, potholes and joint-arrises; not for vertical, overhead or large-area screeding.
For cracks, voids, joint filling, vertical, overhead and mat-damp surfaces without standing water; not a flexible movement-joint sealant.
For prepared dry or damp—not wet—substrates; it is not the final wearing surface.
An industrial floor finish within a confirmed system; review the complete build-up and TDS.
For projects requiring a self-smoothing industrial wearing surface after all repair and preparation work is complete.
Restore isolated potholes, arrises or details while the surrounding floor remains serviceable.
Reinstate defects, then prepare, prime and coat the treated area as one continuous system.
MortarBond EM90 and PatchBond TX80 publish pot-life and cure information in their individual TDS PDFs. Actual opening time also depends on site temperature, repair depth, any following coating and vehicle load, so one universal “overnight repair” promise would be misleading.

Identify whether the defect is a pothole, joint edge, crack, vertical repair or delamination, then confirm weak concrete, moisture, contamination, movement and traffic. Cut back to sound concrete before selecting a horizontal epoxy mortar or thixotropic repair compound against its TDS.
Both may use a horizontal epoxy mortar, but the detail is not identical. A joint also requires movement assessment, while repair geometry, depth, wheel path and the subsequent joint treatment must be confirmed on site.
MortarBond EM90 is a three-pack solvent-free epoxy mortar for horizontal concrete-floor spalls, potholes and joint-arrises. It is not intended for vertical or overhead repair, or large-area screeding.
PatchBond TX80 is a two-component solvent-free thixotropic epoxy adhesive and repair compound for cracks, voids, joint filling, vertical, overhead and mat-damp substrates without standing water. Moving joints require a movement-capable detail rather than rigid filling alone.
Escalate cracks that widen, repeatedly return, show differential movement, settlement, heave, exposed reinforcement, active water or possible structural distress to a suitably qualified engineering professional.
Some products permit use on mat-damp substrates without standing water, but damp does not mean ponding or persistent negative water pressure. Confirm the water source, substrate condition and applicable product TDS first.
Not always. Local repair can suit an isolated defect when the surrounding floor remains serviceable. Where the old coating is generally worn, contaminated or delaminating, wider preparation and recoating can provide a more continuous, cleanable surface.
There is no universal promise. Return to service depends on product, temperature, repair depth, follow-on coatings and the actual load. Plan it against the relevant TDS and site sequence.
Send context and close-up photos, dimensions and depth, movement history, moisture, traffic, existing coating and the available shutdown window. You can start with photos even when some details are unknown.
