Mixing

Give the container a shake prior to application.

Application

Floors – must be dry before application for Concroff to be most effective.

Brush in undiluted Watco Concroff with a stiff broom, scrub and leave it for at least 15 minutes to allow it to penetrate and to lift the contamination out of the surface. A little water may be added to the floor at this stage to aid spreading; (too much water will reduce the effectiveness of Concroff).

Scrub the floor again with a stiff broom or a mechanical scrubber to loosen the dirt deposits.

Rinse with clean, cold water preferably whilst continuing to scrub. Where grease and oil has penetrated into concrete, Concroff will help to draw it out. Check the surface a few hours after application.

If more oil has risen to the surface a repeat application will be required.

Limitations

Do not use on a previously painted or sealed surface. This powerful formulation may stain or soften existing paint or sealers.

Once Concroff has been used to remove oil or grease it must not be allowed to enter sewers and should never be allowed to enter rainwater drains or open water courses. In such cases it should be removed from the floor by the use of a squeegee in conjunction with absorbent material (sawdust or sand) and disposed of as chemical waste.
