While using dry or wet sanding as the best technique kindly ensure that you use the correct number and size of abrasive paper. If you wish to go ahead with mechanical means, it is advantageous to use a mechanical sander (belt or disc) with a vacuum exhaust attachment. Important: Always wear a dust and respiratory mask when dry sanding
Following sanding, the surface must be thoroughly cleaned again since sanding dust can adhere to it more firmly than one would expect. Rinsing with water or removal with compressed air is often only partially effective. A thorough removal of sanding dust can be achieved through a combination of brushing and rinsing- hose in one hand, brush in the other. Re-rinse with ample fresh water. Before coating can commence, surface must be absolutely dry.
