Application: B-555OL-UUU is formulated for spraying as supplied. It is strongly recommended that the material be
mixed before use. Optimum application temperature is 65 F – 90 F (18 C – 32 C). Apply in several thin, overlapping
passes rather than a single heavier coat; this will help avoid porosity, solvent entrapment, and sagging. The suggested
wet film thickness is 18 – 22 mils (0.45 – 0.56 mm). Brushing is not recommended.
Storage and Handling: B-555OL-UUU should be stored in closed, opaque containers at temperatures above freezing
but not exceeding 77 F (25 C). Do not keep gel coats near catalyst storage areas. To avoid decomposition keep away
from direct sunlight and excess heat. Refer to the Safety Data Sheet for further details on safety and storage.
