Crestafix F26 is a water resistant, low-density polyester-based fairing compound. Crestafix F26 has good adhesion to cured fibre-reinforced polyester and vinylester laminates. It sands easily, gives a hard finish after a full cure, yet is not brittle and has good impact strength. F26 is a suitable base for all marine finishes such as polyester, urethane and epoxy paints.
Crestafix F26 is often covered, prior to painting, with our sprayable polyester-based primer Poly-Fill to hide surface imperfections and pinholes in order to obtain a high-quality finish. Below the waterline, they must be covered with epoxy bottom paints, or we recommend to use Poly-Fair F24VE, the vinylester version of F26.
F26 fairing compound is used primarily in the boat building and fiberglass fabrication industries for fairing and sanding plugs, moulds, one-off custom boats, fairing of lead keels (if not coated with epoxy), fairing of keel-to-hull joints, repair of damaged fibreglass parts and mould re-work or modification.
