What does the slab need before you start?

Concrete or screed of at least 25 N/mm², clean and free of oil. We check the moisture before any primer goes on.

How is the surface prepared?

By vacuum shot-blasting where possible, or by planing, grit blasting or grinding, until the surface shows a profile.

What goes under a heavy-duty floor?

EPILOX 246 epoxy mortar, trowelled on at 3 to 6 mm, under the wearing coat.

What do you lay in car parks?

A floor hardener power-floated into the fresh concrete, or a polyurethane deck coating.

All systems, by building zone

Industrial and Car Park Flooring.

Factory floors, loading bays, car parks and plant rooms. Forklifts, chemicals and hot wash-downs, on a floor that has to stay seamless and cleanable. This page sets out what the slab needs, the layers and the order of work.

The build-up.

Three layers over the structural slab.

From the slab up

Substrate preparationShot-blasted or ground, moisture checked. The slab must be sound, clean and free of oil before any primer goes on.
EPIPRIMEEpoxy primer, applied by roller.
EPITHANE CPSMedium-duty polyurethane self-levelling screed. Heavier duty takes EPILOX 246 epoxy mortar underneath; car parks take a floor hardener or a PU deck coating instead.

How the job runs.

We check the slabConcrete or screed of at least 25 N/mm², with its moisture checked, and free of oil, paint and loose material.
Surface preparationVacuum shot-blasting is preferred. Planing, grit blasting or grinding are used where they suit, until the surface shows a profile.
EPIPRIMEThe epoxy primer goes on by roller, within its pot life and without thinning.
EPILOX 246, under heavy-duty floorsThe epoxy mortar is trowelled on at 3 to 6 mm before the wearing coat.
EPITHANE CPSThe polyurethane coat is applied within its pot life and spike-rolled at once to release air.

Joints, ramps and car parks.

Moving joints
Every moving joint in the slab is carried through the floor finish. See expansion and construction joints.
Car park decks
A non-metallic floor hardener is spread onto the fresh concrete and power-floated in.
Car park ramps
O-ring patterns are formed in the surface of the ramp while the concrete is fresh.
Curing
A power-floated slab cures for at least seven days before it is loaded.

These products are made by CHEMIND. Where a project specifies another manufacturer's system, we apply that instead.
