Buying-stage answer

A failed epoxy floor should be assessed before repair or recoating so loose areas, contamination, moisture, and the underlying slab condition are understood.
Concrete coating removal is required when old coatings, adhesives, membranes, or sealers would stop a new floor system bonding properly.
Typical removal budgets range from $20 to $80 per sqm, with heavy elastomeric membranes, thick epoxy, and adhesive residues costing more.
Successful removal includes dust-managed grinding or tooling, edge work, waste handling, and final profiling for the next system.

Service explanation

Surface Master removes failed coatings, paint, epoxy, sealers, adhesives, levelling compounds, and some membrane systems using dust-managed diamond grinding and surface preparation equipment. The goal is not just removal; it is creating a measurable profile for the next coating, overlay, or polished finish.

Pricing factors

Cost depends on coating thickness, hardness, bond strength, number of layers, floor area, edge detail, access, dust controls, disposal, whether shot blasting or heavier tooling is required, and the finish standard needed after removal.

Removal preparation requirements

Identify the coating type, thickness, adhesion, likely contaminants, and desired next finish.
Clear fixtures, loose stock, skirting risks, and sensitive equipment from grinding zones.
Plan dust extraction, noise windows, waste handling, and access routes.
Allow for test patches because unknown coatings can change tooling and production rates.

Removal risk prevention

Do not quote removal only by area when coating type and bond strength are unknown.
Check whether old coatings may conceal slab cracks, moisture, oil, or weak topping layers.
Avoid leaving edges, corners, and thresholds partly coated before a new system is applied.
Confirm the required profile after removal so the next coating can bond correctly.

Commercial FAQs

Can a failed epoxy floor be repaired instead of fully removed?

Sometimes. Localised damage may be repairable when the remaining coating is sound and compatible, but widespread delamination, contamination, moisture, or an unknown coating system can make full removal the safer option. A site assessment and test area determine the practical scope.

Can you remove old epoxy before recoating?

Yes. Existing epoxy is mechanically removed or profiled depending on its condition and the specification for the new system.

Is coating removal dusty?

Grinding creates dust, so commercial work is planned with dust extraction, isolation, and cleanup controls.

Do all old coatings need removal?

No. Sound compatible coatings may be abraded and recoated, but failed, contaminated, or incompatible coatings should be removed.
