Application Procedure
1.Flush all equipment with thinner or Amercoat 12 before use.
2.Stir resin and cure using an explosion-proof powermixer to disperse pigments.
3.Add cure to resin. Mix thoroughly until uniformly blended to a workable consistency. For low temperature application, use Amercoat 861 accelerator. Do not exceed the 1 pint Amercoat 861 accelerator per 5 gallon unit recommendation.
4.Do not mix more material than can be used within the expected pot life.
5.For optimumapplication,material should be from50° to 90 °F (10° to 32 °C). Above 122 °F (50 °C), saggingmay occur.
6.Use only PPG recommended thinners. For potable water applications, see current NSF listing atwww.nsf.org for approved thinners and thinning restrictions. For other applications, above 85 °F (29 °C) use Amercoat 8, or 101 at lower temperatures use Amercoat 65. A small amount of thinner greatly reduces viscosity; excessive thinning will cause running or sagging. Thin cautiously as follows:
Amercoat 8 or 65 thinner400400AL
Airless - up to¼pt/gal1½pt/gal
Conventional - up to½pt/gal1½pt/gal

Below 50 °F additional thinning may be needed and multiple coats required to achieve specified thickness.
Above 122 °F, up to 250 °F surface temperatures, use Amercoat 101 thinner sparingly to promote flow and leveling. Excessive thinning will cause running or sagging.
7.To minimize orange peel appearance, adjust conventional spray equipment to obtain adequate atomization at lowest air pressure.
8.Apply a wet coat in even, parallel passes with 50 percent overlap to avoid holidays, bare areas and pinholes. If required, cross spray at right angles.
9.When applying Amerlock 400 directly over inorganic zincs or zinc rich primers, amist coat/full coat technique may be required to minimize bubbling. This will depend on the age of the Dimetcote, surface roughness and conditions during curing.
Note . Do not use Amerlock 400AL onwater damp surfaces
10.Ventilate confined areaswith clean air between coats and while curing the final coat. Prevent moisture condensation on the surface between coats.
11.Repair damaged areas by brush or spray.
12.Clean equipment with thinner or Amercoat 12 immediately after use.
