Bubble Roller — Fiberglass Resin Laminating Tool What it does Removes air bubbles and consolidates resin in freshly laid fiberglass for a smoother, more uniform finish. Designed as a manual laminating roller to improve adhesion between layers and reduce pinholes and voids. Key benefits Faster, cleaner results: speeds up finishing and reduces rework by quickly eliminating trapped air. Consistent surface quality: helps produce a flatter, more professional laminate ready for sanding or gelcoat. Durable construction: made from aluminum alloy with hardness for longterm, wearresistant use. Features Function: fiberglass resin laminating (bubble) roller for use immediately after laying fiberglass and resin. Material: aluminum alloy — sturdy, hardness, and wear resistant for reliable performance during repeated use. Practical hand tool: compact, handheld operation that improves work efficiency on small to mediumsized projects. Compatible applications Fiberglass repairs and laminating projects. Ideal for tub, shower, and bathtub and refinishing. Suitable for boat , including hull patching and small structural laminates. Typical use scenarios Boat hull : after laying fiberglass cloth and resin over a patch, roll the surface to expel air and consolidate the laminate before curing. Bathtub or shower refinishing: use the roller when applying fiberglass layers to fill chips or cracks and achieve a smooth base for topcoats. Small panel fabrication: consolidate resin in custom fiberglass panels or patches to reduce voids and improve bonding between layers. Usage note Use on freshly applied resin and laminate; apply steady, even pressure and roll across the surface to release trapped air and level the resin.
