Properties

Instructions for use

Cleaning brickwork & rust stains from concrete

A small trial area should be cleaned first to determine the most suitable Fosroc Acid Etch dilution. Pre-wet the surface, then, using a sponge, rub the affected areas with a solution of Fosroc Acid Etch and water. Strength of the solution required will vary but should be between 1:1 and 1:4 (by volume) Fosroc Acid Etch to water.

When the action has finished, wash down thoroughly with clean water. As treatment with Fosroc Acid Etch can alter the surface finish of concrete, the minimum concentration necessary for effective removal of stains should be employed.

The surface should be washed down with water immediately treatment is complete.

Cleaning large items of equipment

(Examples are readymix trucks, concrete mixers or barrows).

Fosroc Acid Etch should be liberally applied to the deposits by a soft broom and allowed to soak overnight if possible. If the surfaces of the deposit can be cracked by mechanical means this will speed up the operation.

In severe cases more than one application may be necessary. On completion, dissolved deposits and loose material should be brushed and washed away with clean water.

Cleaning small tools

Use Fosroc Acid Etch as a dip. The tools should be soaked overnight, then taken out and washed with clean water to remove all loosely adhering materials. Care should be taken to avoid prolonged contact between Fosroc Acid Etch and zinc or aluminium parts of tools, such as rivets, etc.

Cleaning concrete floors

Pre-wet the floors, then, using a stiff bristle broom, brush the affected areas with a solution of Fosroc Acid Etch and water. Strength of the solution required will vary but should be between 1:1 and 1:4 Fosroc Acid Etch to water. When the action has finished, wash down thoroughly with clean water.

Oil or grease should be removed by treatment with a suitable chemical degreaser followed by water or steam cleaning. Where heavy contamination occurs, as in garages or workshops, pre-treatment with Fosroc Acid Etch assists in freeing oil or grease and renders the action of the degreaser used more effective.

Removal of rust and mill scale

After wire brushing to remove loose material, apply a solution of Fosroc Acid Etch and water using a soft broom or brush and leave to act for 20 – 40 minutes. Strength of the solution required will normally be between 1:1 and 1:4 Fosroc Acid Etch to water. Wire brush again to remove remaining loose material and finish by thoroughly washing down with clean water. Repeat if necessary.

Spillage

Spillages should be hosed down with plenty of water.

Caution

Fosroc Acid Etch is acid based and should be handled with care. Acid vapours from undiluted product can damage nearby surfaces, notably causing rusting of unprotected steel. If in doubt about its effect on a material, test a small area before general application.
