Key Features
Spray-like smooth finish
High-density foam delivers a smooth, even coat that looks spray-applied — no brush strokes, no texture, no lap marks on flat surfaces.
Lint-free application
Foam construction leaves zero lint or fiber in the paint film — critical for gloss, semi-gloss, and enamel finishes where lint is visible.
4" compact size
The right size for cabinets, doors, furniture, trim, molding, and shelves — where a 9" roller is too wide and a brush leaves marks.
Works with all paint types
Compatible with latex, oil-based paint, chalk paint, varnish, urethane, enamel, stain, and waterborne finishes.

Pro tips: Roll slowly to prevent air bubbles — foam saturates quickly so keep dips light. Apply two or three thin coats rather than one heavy coat for a smoother result. Foam rollers are single-use — clean immediately after use to extend life, or replace inexpensively for the next coat.
