Floor preparation prior to painting:

Floors with heavy contamination – should be reasonably dry for Bio D to be most effective. Brush in undiluted Watco Bio D 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. 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. If further applications are required, the floor should be reasonably dry before repeating the process.

Floors with light-medium contamination – as above but Bio D may be diluted.

Floor maintenance -  Apply undiluted Watco Bio D with a stiff broom to the surface and leave for 5-10 minutes for penetration. Then scrub with a stiff broom or mechanical scrubber. Rinsing with clean cold water will float away oil and grease. Bio-D can be diluted with up to 10 times water for cleaning existing painted or bare floor surfaces. 

Machinery - Liberally coat oily and greasy parts using a soft brush. Leave for 5-15 minutes according to hardness of oil or grease, then rinse well with water. Protect materials that might be damaged or must not become wet. 

Warning - Watco Bio D is biodegradable, but a mixture of Bio D, oil and grease should not be allowed to enter rainwater drains or open water courses. The mixture can be removed from the floor using a wet vacuum and disposed of as chemical waste. 

Surfaces cleaned with solvent based degreasants generally require the use of a second stage cleaner to remove residues prior to painting. Surfaces washed with Watco Bio D and then rinsed with water are left ready for painting. May be diluted with water for removal of light to medium contamination.
