wood filler

[jkgroff]

What is a good filler to use? I've just replaced part of my floor. There are gaps between areas of plywood that I want to fill before I glass over the plywood. I tried to fill with epoxy but the liquid drips through before it hardens.<br /><br />Thanks

Try epoxy filled with milled fiberglass. Make a paste of a ketchup consistency and add a litte more if you need greater thickness.

Re: wood filler

any epoxy store will sell "filler" to thicken it.

I just put saw dust in my polyester resin to thicken it.<br /><br />Greg

Re: wood filler

Filler material can range from kitchen baking flour, talcum, sawdust, metal filings to commercial fillers such as Cabocil or Aerocil.<br /><br />For filling wood, I personally thicken resin with the dust from my orbital palm sander collection bag, but nearly any sawdust will do fine.

Re: wood filler

Thanks for the great tips, I took a pair of scissors and cut fiberglass matt into little strands and mixed that with epoxy. It worked great.

Re: wood filler

What are the advantages of commercial products like cabosil?<br /><br />Sawdust seems to work fine for me but I have never used any of the products you buy. I have herd those micro balloon things used work well.<br /><br />Greg
