auto-truck-repair

One of the many Mobil Oil service stations completed across the US & Canada.

The franchisee/owner of the station removed all the equipment from the repair bays late in the afternoon. He then de-greased the floor and forced flame dried it with a weed burner. The crews arrived at six PM and began shot blasting the floor.

When the station was built, a red colored "shake" was broadcast into the top surface of the fresh concrete and trowelled in.

Shot blasting removed that surface and any inferior laitance on the top surface of the concrete, to insure deep penetration of the ARR primer into the concrete substrate.

Small areas in different locations on the floor are primed and allowed to cure in a quick twenty minutes.

Bond tests are performed to insure surface preparation is adequate for deep penetration of the primer into the substrate.

After the primer cures, a small square patty about a half inch high of ARR resin and sand are applied to the surface.

While these bond test patty's cure/dry, surface preparation and cleaning continues.

Dust controlled diamond grinders are used to prepare the concrete in areas inaccessible to the shot blast machine.

Electric blowers were used to remove fine debris and dust.

After curing completely in a quick twenty minutes, bond tests are chiseled of the floor with a hammer and coal chisel.

Bond tests are examined.

The whole underside of the bond test should be covered in pulled out concrete and the large and small aggregate in the concrete should be fractured in half.

The fast cure feature of ARR resins make it possible to test the floor for adhesion before the floor coating is installed. Another advantage of fast cure ARR resins.

After final blow-down, spot priming is applied to rough and discontinious areas of the floor and allowed to cure.

Thickened ARR fill resin is applied to the floor in the rough areas.

Trowels are used to flatten the fill material.

Large pool trowels are then used to smooth the fill material and blend it into the the existing floor.

A 'blush' (lightly pigmented) primer is applied.

Blush priming continues.

White aluminum oxide for skid resistance is lightly broadcast into the wet 'blush' primer.

After the first 'blush' prime coat has cured in about twenty minutes, a second fully pigmented coat is applied.

Detail work around drains and vertical edges are coated.

Under cabinets are detailed with the second coat prior to coating the open area of the shop.

Second and final coat begins in the open area of the shop.

Finishing up the final pigmented topcoat.

Dawn is breaking and the trucks are being loaded with the flooring tools and equipment.

Customers are starting to show up and the mechanics bays are ready for the equipment to be moved in without missing a day of work.
