Product Details

Interlux Interfill 833 Fast Cure Epoxy Finishing Fairing Compound 2-part epoxy putty designed for fairing and smoothing a surface when a fine finish is required. Interfill Epoxy Filler can be used above the waterline to prepare the surface prior to applying topside finishes, and can be used to fill pinholes between coats of two-part polyurethanes due to its ability to trowel to a very line, smooth finish. Interfill Epoxy Filler can also be used below the waterline to fill blisters and as part of a keel fairing system.

If Interfill Epoxy Filler is used below the waterline, it must be overcoated with four coats of Interprotect 2000E/2001E. The cured epoxy is easy to sand, has excellent solvent resistance, and will not be attacked by the strong solvent in two-part polyurethanes or epoxies.

Application Method Trowel, filling knife, fairing batten

worth it
By sailorstud from panama city, fl

restoring the fibreglass on my 1984 sailboat. Used a pressure sprayer to remove old non skid, but it left a lot of "divots". Used this product along with a flexible trowel to rapidly fill all the holes. Easy to sand. Regular cure takes a long time to cure before sanding. Will try the fast cure next. This is better then trying to mix your own fairing compound.

Bottom Line Yes, I would recommend to a friend
