PACKAGING
10 gallon kit: 5 gallons Part-A (Isocyanate side) and 5 gallons
Part-B (Resin side).
100 gallon kit: 50 gallons Part-A (Isocyanate side) and 50
gallons Part-B (Resin side).
COVERAGE
Polyeuro® 6881 may be applied at any rate to achieve desired
thickness. Theoretical coverage for 1 mil thickness is one
gallon per 1600 sq. ft.
SURFACE PREPARATION
In general, coating performance and adhesion are directly
proportional to surface preparation. Most failures in the
