Watco Concroff
Litres required: 0.00L
Based on 4.0 m² per litre- Lightwork of heavy-duty repairs
- Structural strength solutions
Watco Concroff is a powerful water based degreaser for heavily contaminated bare floors. It lifts stubborn oil, grease and ingrained dirt from concrete and other suitable unsealed surfaces, making it a practical preparation cleaner for garages, engineering workshops, factories and maintenance areas.
Where oily deposits have built up over time, painting directly over them can compromise the coating system. Concroff helps remove this contamination before the next stage of floor preparation. Its concentrated, solvent free formulation is worked into the surface, allowed to penetrate, then scrubbed and rinsed away. It can also be used on suitable machinery, with water-sensitive components protected.
- Heavy duty cleaning for bare concrete and other compatible unsealed surfaces.
- Water based, low odour formulation.
- Suitable for interior and exterior preparation.
Surface Preparation
Remove loose dirt and scrape away thick deposits of grease first. Floors must be dry before treatment for the cleaner to work most effectively. Protect surrounding materials and equipment. This is a preparation product for bare surfaces: do not apply it to an existing painted or sealed floor.

Coverage
A 5L container treats approximately 20m² of heavily contaminated floor (4m²/L). The actual area depends on surface texture and the extent of contamination. Stubborn deposits may need another application.
Directions for Use
- Brush undiluted Concroff into the dry floor and scrub thoroughly. A small amount of water may help spreading, but excessive dilution reduces effectiveness.
- Leave for at least 15 minutes to penetrate the deposits, then scrub again with a stiff broom or mechanical scrubber.
- Rinse thoroughly with clean, cold water while agitating the floor. Collect contaminated washings.
- Repeat on persistent contamination after the surface is reasonably dry. Before painting, allow the cleaned floor to dry thoroughly.
Limitations
Do not use on previously painted or sealed surfaces: this strong cleaner can stain or soften the finish. Protect from freezing. Prevent oil-contaminated washings entering drains, sewers and watercourses; collect and dispose of them as appropriate chemical waste. For machinery, follow the technical sheet and keep rinse water away from sensitive parts.
Product FAQs
Is Concroff suitable for painted floors?
No. The technical sheet excludes painted and sealed surfaces because the cleaner may stain or soften them.
Should the floor be wet before cleaning?
No. Start with a dry floor and use the cleaner undiluted for heavy contamination. A little water can aid spreading, but too much reduces effectiveness.
How much does one container cover?
Approximately 20m² per 5L for heavy contamination. Repeated treatment may be needed for persistent deposits.
Can I paint straight after rinsing?
Allow all cleaner residue to be removed and the floor to dry thoroughly before applying a compatible primer or coating.
