Coatings Test Conclusions
Polyurethane, Acrylic, and Spar: ᢗ% Reduction
Oil Based Finish: 80-97% Reduction, Average=90%
Oil Finish wears Uniformly and Does not Chip – May Be Preferred on Foot Traffic Surfaces
Application of these coatings effectively eliminated any surface removable arsenic for up to one year.
Better Side By Side Comparisons Need to be Carried Out (Different Coatings on Matched Surfaces compared to uncoated – Correct for time effects observed on a particular sample date)
