Technical FAQ
Can Brightside be used below the waterline?
No. Brightside is designed for use above the waterline only.
Is this a one-part or two-part paint?
It is a one-part polyurethane, so no curing agent is needed.
When should the topsides be recoated?
Recoat when the existing finish becomes faded, chalked, scratched, heavily stained or worn through.
Do I need to sand between coats?
Yes. Interlux specifies sanding between coats for adhesion and gloss.
Parts Desk Insights
Best use case: Refreshing topsides, cabin sides and deck structures with a classic warm beige, high-gloss finish without the complexity of a two-part system.
Most common mistake: Applying the paint too heavily. Brightside levels best in thin coats, and skipping surface preparation or sanding between coats reduces adhesion and gloss.
Sizing and fitment guidance: This listing is 1 US quart, covering approximately 137 sq ft by brush per coat. Multiply your surface area by the number of coats planned, and allow extra for texture and application loss. If you are matching an existing finish, confirm colour code 4217 before ordering.
