Prior to painting the surface must be well prepared and free from loosely adhering material and contamination such as dirt, grease, oil, polish etc.
Power-floated Concrete, creates adhesion difficulties and therefore should not be painted without successful preparatory treatment. This can be done by either 'track blasting' or using a 'floor etchant', to the manufactures recommendations. Track blasting is the most successful of the two treatment and should be considered where the concrete is particularly well polished, it can also often be more economic on large areas.
This system is not suitable for external use or areas subjected to prolonged contact with wet vehicle tyres.
It is important to ensure that the floor has an effective damp-proof membrane, no damp problems and a moisture content not greater that 5%. A small sheet of polythene sealed flat and to the surface and left overnight will often highlight if there is any moisture present, however a Hygrometer moisture meter would be required to obtain a more accurate assessment .
In order to dry correctly, the coatings (especially waterbased types) require good air flow at temperatures above 10 degrees centigrade with a relative humidity below 85%. Do not recoat or use the floor until the coating is fully dry.
Optimum chemical and abrasion resistance will not be achieved until the final finishing coat is allowed to dry for a minimum of seven days. Optimum intercoat adhesion properties will only be achieved if subsequent coats are applied within seven days. Refer to Data Sheet for further information.
*Use 'track blasting' or 'floor etchant'(*See ICI Site Work Instructions SW4.83 and SW4.82) Prepare the floor to remove surface laitance and to open the pores of the surface thus providing a suitable mechanical 'key'. Use an emulsifying oil and grease remover to clean the surface if necessary. Rinse surfaces thoroughly with frequent changes of clean water to remove all residues. Wet vacuum equipment or absorbent material may be required to soak up excessive water. Allow to fully dry. After pre-treatment ensure that the surface is thoroughly dry and open enough to allow penetration of the floor paint. Test the surface by applying a droplet of water on to it, the water should be absorbed by the surface within a minute. A trial would be recommended if in doubt. Before painting, sweep and vacuum the floor to remove any surface dust. Make any repairs necessary using a levelling compound which is suitable for the usage and loading requirements of the area involved.

Remove all loose and defective coatings back to a firm edge by whatever means appropriate i.e.; scraping, manual or mechanical abrading or 'track blasting' Treat any exposed polished areas by either using a 'floor etchant' or 'track blasting'.(*See ICI Site Work Instructions SW4.83 and SW4.82). Wash the sound painted surface to remove dirt etc. Use an emulsifying oil and grease remover to clean the surface if necessary. Rinse surfaces thoroughly with frequent changes of clean water to remove all residues. Whilst wet, abrade the surface with suitable abrasive. Rinse and allow to dry.
