Anyone have any suggestions for patching several dings and cracks in 10 year old relief carvings in 1" Precision Board so that the repairs are fairly inconspicuous? The perfectionist in me wants to match the natural texture of the HDU. These are rather complex dimensional carvings and I do not want to go through the work of hand carving them from scratch.

I just use bondo/spackle

Coastal Enterprises also has some good fillers.

I've used a lightweight exterior spackle, with good results. It's a pale pink color, when you put it on, but dries white. Easy to sand and has a little "porous" look to it (like the HDU).
Not as tough as the bondo, but it worked pretty well for me.

I'm with Wayne. I use Coastal Enterprises Hard Coat for repairing hdu. It comes in two parts, one powder one liquid, that you mix. I've repaired many hdu signs with this stuff. Most you can't tell there was ever any damage.

Dave and Wayne... I was not aware of such product... thank you for the information.

Marty, I use Bono or Magic Sculpt...In the case of the magic sculpt you can, once divot is filled, use a scrap piece of HDU (wet it lightly) and press into fill to get same texture...The reason for the wetting is so when you press in the scrap and lift it away it doesn't bring any of you fill up with it... hope that helps..

I like that suggestion, Pat. I was even entertaining the idea of crumbling up some HDU and mixing it with some kind of glue like using sawdust mixed with glue to make a filler.

Ditto on the magic sculpt.

Anyone ever try Gorilla glue to repair HDU? Saw several videos on YouTube of repairs to lightweight foam.
Posted by Dave Sherby (Member # 698) on :
No, but I've used it to sculpt with. This tree is gorilla Glue and a little bit of water mixed in, then quickly spread over the entire raised tree. Build it a little thicker away from the edges. As it starts to expand, I worked it with a Popsicle stick for texture, then just let it rise and harden.

Nice Dave... I'm having success with my project. I learned on a YouTube video that mixing in a little vinegar and baking soda will give you finer air bubbles and harden faster and harder.
