Thread: Soft rezi

    Soft rezi

    I'm fixing up an epoxy board and my epoxy resin kit doesn't really harden up compared to fixing a regular Pu board with q cell and stuff.. I let it dry for over a day, and it's hard enough to surf but to soft to sand down. Is this normal for epoxy? How do I fix? Should I just not sand it?

    If its too soft to sand after 24 hours, its not normal and probably is not properly repaired. ...the epoxy resin didnt set up properly. What kind of epoxy kit did you use?

    Make sure you mix it up real good and make sure it is the correct ratio of epoxy to hardener. Sometimes if you are using small amounts the ratio has to be perfect for it to harden using higher amounts will have a lesser chance for error. For example if you use .5 oz to and 1oz and it didnt work use 1oz to 2oz (hardener to epoxy).

    Every epoxy sun cure resin I have ever used is like that. Stays tacky and never fully hardens, I hate that stuff.

    Feesh's advise is solid. It should cure hard as a rock. If it didn't, your mix ratio was off. If it's water tight, just sand it as best you can and ride it. If not, or if you want to do it over, cut out the repair and try it again. I recommend mixing the entire contents (they usually give you the exact amount of each needed), and wasting what you don't use, or putting a dixie cup on a digital scale, taring the scale, then mixing the ratio by weight per the manufacturer's specifications.

    Have you tried Acetone to get the resin off your fingers? Is the area of the repair still half way clean, meaning litle to no debri in it, other than the oils form your skin from touching it? If it is I would try mixing another batch of resin (mixing it hot, more hardener with less working time) . If that resin is hot enough it may possibly get the resin in the original reapir to kick off, I am not sure, but thats what I would try. Also maybe apply heat via a hairdryer (dont get to close to the board) right after applying the new resin. I am no epoxy expert granted, but since its either cut out the repair or try to get the original glass job to kick off I would try the latter first maybe.
    Does expoxy resins have laminating and sanding resins? Does your kit have two resin bottles in it? IF so check to see if you used laminating resin, maybe in expoy resins they dont have laminating resins but if they do you might have used that as opposed to sanding resin which would cause the resin to never get hard without a hot coat of sanding resin on top.

    Uncured epoxy can be removed with white distilled vinegar. It can also be removed with any citrus based cleaner, like gojo... I like the kind with pumice.
