mechanical scarification. Seal using SP-1264 Damp Concrete Primer Sealer.

MIXING RATIO

Brush Grade or Spray Grade; By Volume: 3 Parts Base to 1 Part Activator.

RECOMMENDED FILM THICKNESS:

 Pipelines: 0.50 mm minimum to 3.0 mm maximum (20 mils to 120 mils)

 Tank Lining: 0.50 mm minimum to 3.0 mm maximum (20 mils to 120 mils)

RE-COAT INTERVAL:

 Spray Grade @ 25C (77F) Maximum: 12 hours

 Brush Grade @ 25°C (77°F) Maximum: 14 hours

 SP-1386

®

is a one-coat application system. However, if there are areas below the specified thickness

and the coating has cured beyond the specified re-coat window, roughening of the surface is

necessary to ensure inter-coat adhesion. Small areas  316 sq. cm. ( 49 sq. in.) may be sanded using

a medium grit (80-100) carborundum cloth. All dust from the sanding or blast roughening must be

removed from the surface prior to the application of the coating.
