System Three 1-Quart SculpWood Moldable Epoxy Putty, 90301

Works well, did the job, though rather expensive

Great product!!!!! Works fantastic!!!

This is the most amazing stuff in the world. I have used Bondo, plastic wood (wood filler) and other products in the past to fix holes in wood. This time I was faced with the job f filling in a large hole in my door to replace an ancient handleset with a new modern one. The holes required are entirely different geometry and I thought I was going to have to cut up pieces of wood to match the old cut-outs, then piece them in and glue them. The main hole was way to large for Bondo - and being down by the sea I also worried that the shrinking and swelling of the door might eventually lead to cracking. When I described the challenge, a friend of mine recommend this product to me. I could not have been more pleased with it's performance. It's simple to mix because you just have to mix equal parts. It stays pliable and workable for about 4-6 hours, so there's plenty of time to scrape and mold once you get it in place. It handles like play-dough, soft and pliable, but with enough body to support itself. It's very light and cures in about 24 hours rock solid. I was concerned about it's ability to adhere since it's really not all that sticky when you work with. You will want to wear plastic gloves because there are chemical reactions involved here, but it's really no more sticky than play-dough. So I took some leftover and made a couple little balls about 1" in diameter and (a) placed them gently together (like a snow man) and (b) placed them gently on a slab of wood. The next day, once they cured, tried to break them apart. I needed to hit the little figure with a hammer to remove it from the wood slab and never was able to cleanly break apart the balls, so the adhesion I was worried about is a non-issue. This stuff sticks well, even to flat surfaces. It cures a light brown color and is much lighter than wood or Bondo when it's done. It sands like wood and can be painted like wood. As my locksmith pointed out, however, it does not chisel like wood, so if you need to make cutouts, it's good to think ahead and mold these when the material is pliable, otherwise you may need a dremel tool to work the small bits. Pros: - easy to mix - easy to work - pliable and workable for 4-6 hours - dries rock hard - sandable and paintable like wood - waterproof Cons: - takes 24 hours to cure - does not chisel like wood (tends to shatter) This is definitely my new "go to" patching material for high-use areas.

I have used this material for this last year or two during renovations of a 100 yr old abandoned house. It is simple to use, although having sculpting skills makes it easier. We have used it to replace missing corners and architectural features, fill big gouges where crowbars were used to open wood windows, and restore areas of rot. We use iron oxide to color it a rich reddish brown that will then pick up wood stain and other finishes. It becomes virtually invisible and is remarkably strong. It is doing well in areas that are functional and not just decorative. A little bit goes a long ways, so start by mixing less than you think you'll need. No other wood filler comes close to the usefulness and strength of this system, and it has been a godsend for this overwhelming project.

I am not one for giving 5 star reviews without a good reason about anything but so far in my experience I am very impressed and pleased with the results of this moldable epoxy. It takes a little getting used to since its very light and airy feeling when mixing an applying but once cured it is nice and strong. A nice attribute is that it is has such a uniform consistency once cured that it is very easy to sad and chisel to whatever shape you need. just fill th void a little proud of the surface and you can easily modify it to match up exactly then paint it to have a repair that looks as good as new. My only suggestion is to use smooth protective gloves over textured because it does want to stick to the gloves a bit also... not to a bad degree but the smoother the glove the easier it is to mix and mould with your hands.

I wanted to try to repair the bottom corner on a large exterior picture window frame that had about 3" of wood completely rotted out. My goal was to stabilize it for this winter before replacing it next summer. Did the resin step and applied the putty within an hour yesterday afternoon & let it dry overnight. (I am in CO and was pushing the temp. min. for the resin @ 49 degrees, but went ahead and gave it a shot.) Went out today & it was wonderful! Putty was hard as a rock. Sanded & painted within an hour and I couldn't be happier. Love the easy mixability, it's light weight, pliable & the low temp. range on putty is a plus. Big thanks to all the reviewers & the pics... this 'old lady' w/this old house, really relies on honest reviews for all kinds of d.i.y. materials, tools, etc. I'm sure I saved a lot of $$$ & will hopefully do a better 'finish' the next time around when I'm not wearing Sorels & winter gear. ;)
