System Three 3'' Foam Epoxy Roller Covers, 4-Pack

These foam rollers feature the ideal 1/8'' thickness needed for an even coating of epoxy without runs or sags. Designed as epoxy rollers, they can also be used to spread water-based glues. Ideal for applying thin seal coats, coating and fiberglassing wood, and rolling epoxy barrier coats on fiberglass boats. Great for spreading over large surfaces without absorbing a lot of glue. Applies an approximately 3 mil coating. Use with a 3'' roller frame (sold separately).
