coated e g ship hulls pressure spray equipment is preferred preferably the compressor and regulator are set to produce 60 pounds per square inch of pressure at the spray gun air hose junction average coverage per single coat of spray is 350 square feet per gallon although the spray is non toxic use of a respirator by the spray gun operator is highly recommended the spray gun fluid control valve may be adjusted as required to produce a thin coating on the application surface the spray gun operator 39 s stroke should be rhythmic over a range of 12 to 14 inches per second releasing the spray gun trigger at the end of each stroke to prevent excessive product buildup in the spray overlap areas the coating is allowed to 34 set up 34 e g allow evaporation of the vapor degreaser carrier for 5 to 10 minutes to 34 work 34 the product into the surface it is preferred a mechanical buffer e g electric or air driven applying moderate pressure be used as a guide on a horizontal surface the weight of the buffer apparatus alone will provide adequate pressure as a surface will usually have a slight tackiness after spraying buffing should be continued until the tackiness is eliminated it has been noted after many applications to various surfaces that the higher the ambient temperature the less the tackiness before buffing any subsequent coating added should also be worked in the same manner the spray coating is transparent and has not effected any noticable color change in painted or bare surfaces if for any reason the invention is to be removed as might be the case in repainting a surface wet sanding with wet or dry 600 grit silicon carbide sandpaper is.
