Crestafix F26 (formerly Poly-Fair F26)is a water resistant, low-density polyester-based fairing compound. F26 has good adhesion to cured fiber 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. Catalyst is included.
- Fast setting, with follow-on “cheese state”
- Sufficient time for rasping/filing before a full cure
- Tack-free and good feather-edging
- Easy to apply and spread
- Easy to sand
- Excellent adhesion
- Low shrinkage
Crestafix F26 is a suitable base for all marine finishes such as polyester, urethane and epoxy paints. F26 is often covered, prior to painting, with our sprayable polyester-based primer Poly-Fill to hide surface imperfections and to obtain a high-quality finish. (Please refer to the ATC Poly-Fill Technical Data Sheet). Below the waterline, Crestafix F26 and Poly-Fill must be covered with epoxy bottom paints.
Crestafix F26 fairing compound is used primarily in the boat building and fiberglass fabrication industries for fairing and sanding plugs, molds, one-off custom boats, fairing of lead keels (not if coated with epoxy), fairing of keel to hull joints, repair of damaged fiberglass parts, and mold rework/modification.
