1.Flush all equipmentwith thinner or Amercoat 12 before use.
2.Stir each component separately, thenmix cure into resin and mix until uniform. Slowly stir in zinc dust and mix until uniformly blended. Maintain slow agitation during application to ensure thematerial remains uniformly blended.
3.Thinning may be required; thin with up to ½ pint Amercoat 65 per gallon of Amercoat 68HS.
4.Apply a wet coat in even, parallel passes; overlap each pass 50 percent to avoid holidays, bare areas and pinholes. If required, cross spray at right angles to first pass.
5.Check dry film thickness using nondestructive dry film thickness gauge such as Mikrotest or Elcometer. If less than the specified thickness, apply additional material. Typical dry film thickness is 3mils in one coat, however dry film thickness up to 5mils in one coat is acceptable. Do not exceed 5mils in one coat as excess dry film thickness may result in increased mechanical damage during handling or shipping.
6.Touch up random pinholes, holidays and small damaged or bare areas by brush when filmdry to touch. Larger areas should be resprayed.
7.Clean equipment with thinner or Amercoat 12 immediately after use.
