3"/6" SLOTTED PADDLE ROLLER fiberglass laminating roller bubble roller for resin Laminating Roller project kit for composite Review: A Very Useful Tool When Laminating Glass Fiber - This tool proved to be very useful. I was laminating large (6 ft x 4 ft) sheets of fiberglass, consisting of two layers of (14 ounce per square yard) cloth and enough laminating resin to wet and bond both of them together. I used a cheap bristle paint brush to evenly apply the resin, but this roller proved to be essential to squeeze out air bubbles, push the resin through both layers of the cloth, ensure a very even distribution of resin and deliver a flat well-laminated sheet. I used a laminating formula polyester resin with 1% (by volume) of MEKP catalyst to provide a gel-time of about 30 minutes. Prior to gelling and curing, I quickly dismantled the roller and dropped it (and the paint brush) into a sealable container of acetone. After a few good swirls, I left them to soak. Later, the fairly soft gloppy resin residue in the roller's grooves could be removed with a pointed-edge hacksaw blade (see picture), followed by a stiff brass-bristle wire brushing to restore it to good-as-new condition and ready to reuse.
