    • Fast cure
    • High build (in one coat)
    • High abrasion resistance for drilling applications
    • Does not shield cathodic protection


  • Application

    Surface shall be roughened approximately 1" around all repair areas using a Carborundum cloth or 60 to 80 grit sandpaper and than remove the remaing dust with a clean, dry cloth, brush or clean compressed air.
