![]() A number of Bradite floor coatings are suitable for external use.All surfaces must be dry and dust free before coating.They must be clean, sound, well adhered, well feathered and well abraded. Existing coatings should be checked for compatibility.Wooden floors should be clean and sanded to a smooth finish. For larger areas Vacuum Blast Cleaning or Scarifying may be more appropriate methods of surface preparation.To test concrete or screed floors are suitably prepared for painting, water dropped on the floor should soak in to give a dark patch, not droplets on the surface.Etching may need to be repeated until all laitance (loose cemeticious material) has been removed and the surface has a rough, grainy profile. New power floated and smooth floors should be primed using Bradite ES40 Floor Primer or etched using Bradite TA37 Pre-Treatment for Concrete, then washed with fresh water and allowed to dry.Scrape off loose and flaking material and degrease using Bradite TD39 diluted with 9 parts clean water and a scrubbing action. Ensure that the substrate is thoroughly clean.If it is noticeably darker under the polythene or rubber mat, then the floor is still drying out and must not be painted. This can be tested by taping a piece of polythene or laying a rubber mat onto the surface, leaving it overnight and seeing if the surface has sweated by the following morning. ![]()
