1.1 This test method describes a procedure for semi-quantifying visible surface particulates on steel, non-ferrous metals, and other non-ferrous surfaces (i.e. concrete, sheetrock) intended to be painted/coated. It is suitable for both laboratory and field use and can serve as a permanent record, which can prove useful in resolving future disputes.
KeywordsVisual Surface Contaminants, Foam Tape
For proper bonding of coatings, sealer and overlays, it is important that a prepared surface (i.e. steel, non-ferrous materials, concrete, sheetrock, etc.) be properly cleaned, inspected and recorded. This test method allows contractors, applicators and inspectors to obtain a permanent record of the surface cleanliness prior to application. This allows for evaluation/comparison of the tested foam tape to a certified visual percentages. This permanent sample may also prove useful in resolving future disputes.
