Hi folks,

Have a few 5-foot [or so] vertically oriented, jagged 'cracks' in the wood siding in the pic below, though you can't see them in that pic. But wanted to show the wood siding cause not sure "siding" is the proper term. But it's wood (from 1951 when the house was built).

I assume the way to repair is to dig each crack out, widening it as you would in drywall, then clean them up and fill them.

This is a southwest facing wall in So Ca so the sun beats on it all day. The wood expands and contracts. I want to use a flexible product that will not harden to the point the repair fails later (e.g. Bondo). So am thinking PC-Woody, or Abatron WoodEpox, but have never used either. I heard the former is sticky but maintains its flexibility well, and the latter is good, but what would be easier to work with on a vertical crack?? An epoxy paste like PC Woody, or a clay-like material like WoodEpox? Or is there something else you'd recommend?

Any help would be appreciated. This is my elderly Mom's house and I'm her daughter, so please don't answer in shorthand cause I probably won't know what you're referring to. :biggrin2:

Appreciate it guys.... looking closer I have no idea how to work material into these cracks as they are jagged and range in width, plus have breaks. I like the idea of a workable DAP... what about an injectable foam? Like drilling small port holes working my way up so the foam seeps down into the crack, filling it before expanding?

Oh, Chuck F suggested DAP Alex Ultra 230... sorry. Will look into that one. Thanks Chuck F for also saying how to smooth it over with a wet finger. I am guessing it can't be sanded b/c it remains flexible?... but will Google that now.

This is what you want, pretty sure it's now called sonolastic np1, and it comes in colors, Home depot did stock it, don't know if they still do, might try lowes.

Thanks for that but the job was done b/f I saw this, as I happened to have DAP Alex Ultra 230 on hand. But I will keep this product in mind.

There were more cracks than I thought once I started in (like inside each trim piece) so now I have a huge paint job ahead... had to do so many cracks will probably have to just repaint the entire siding.

Thanks for your help, everyone. Appreciated it!

Thought I'd post a pic of the finished product... painted it too. Not as nice as when you can sand something so it doesn't stand out, but that's more work too, so I'm glad this was the best solution for now.... and from the sidewalk you can't see them anyway... Thanks again, everyone.
