Wood Filling Epoxy Paste

This stuff is awesome. It is the perfect consistency. It spreads easily but is also firm enough not to sag. Dries super hard and the work time is accurate as stated on the container. Many products like this, the more you work it, the harder it is to keep things smooth and you end up making more of a mess trying to fineness it. I found it very easy to fineness and spread. No pinholes or air pockets. I like that you can aggressively sand the product one it dries without it turning to dust or burning into what you just applied. Now that I am confident in it's capabilities, I've already ordered another batch tonuae on other projects.

I buy this product a couple of times a year. I really like it but thier's a bit of a learning curve on how best to use and apply it. After its mixed its sets up slow which is both good and sometimes bad. it stays gooy for awhile so i usually let it sit before i apply it. if you putting it in small cracks then let sit for about 5 minutes or so. if your molding larger repairs then you could wait up to an hour before applying. It sticks to your fingers quite a bit especially when its first mixed so I always spray a little WD-40 on my fingers before touching it. It takes awhile to get good and hard so I always give it atleast 24 hours before sanding. once dry it sticks and stays where you put it and doesn't shrink. Works great for out door projects! i've got some on outdoor windowsills and handrail repairs for 3 years and still holding up great with no issues! it doesn't take stain that well but not sure any plastic wood epoxy does?

They only seem to sell this in a light wood color, which is odd because it barely darkens when you apply stain. YOU ALSO CAN'T PRE-MIX IN STAIN. Maybe oil-based stain would work but PC recommends not mixing with anything liquid. The water-based stain I tried pre-mixing actually left the wood filler like soft rubber even after five days of curing. A comment on my review mentioned that the PC Woody web site says you're supposed to buy dry pigments to add to the filler in order to tint it. I tried to use some online color mixing tools to figure out what color I needed to mix in but the colors I came up with were not even close. It seems real materials don't behave like RGB colors. Unable to find anyone recommending tools or methods of color matching other than experimentation, I picked a dark reddish brown that was the same hue and shade as a stained piece of wood but much lower luminance (using an hsl color picker). Since it was so dark, it only took about 10% pigment to get a stained filler that matched fairly well. The color was "burnt umber" from Earth Pigments Company and I was matching a redwood-toned stain on pine. Since the wood darkens more than the putty when you stain it, you have to pre-color it to be darker than the wood, but not as dark as the stain. The putty turns a disturbingly purplish hue with 5-10% pigment mixed in but ends up matching the wood pretty closely after you stain them both. I don't think you'll ever match it exactly but it's worlds better than untinted putty. Keep in mind that tinting makes more go to waste. I can no longer fill a bunch of voids and stop halfway through one. When I mix another batch, it won't be exactly the same color so filling the other half of where I stopped won't look so great. So you have to stop wherever you think you won't have enough to complete the next void and waste the rest of the batch. If it's still soft enough I suppose you could try mixing some new stuff into the previous batch. As other reviewers have mentioned, the filler is sticky. I think that helps it bond well to wood because when I accidentally cracked a piece of hardened putty off the wood, the putty took a layer of wood with it - no part of the putty pulled away from the wood it had been touching. Unfortunately the stickiness makes it stick to your tool as well, so as you try to smear it into a hole it will pull away from one side of the hole because it's sticking to the tool. You can keep pushing it down and working it back and forth until it bonds well to the wood, but you can't get a very smooth finish unless you use denatured alcohol on your tool. I later discovered that using a metal putty knife such as Allway Tools 1-1/2-Inch Stiff Nylon Handle Putty Knife works much better than a plastic putty knife for smoothing. Even with metal, it's pretty inevitable that you'll have to sand it thoroughly after it dries or it just looks sloppy. With some practice and the use of alcohol it may be possible to get it smooth and avoid much sanding, but my attempts at that didn't feel any faster than just sanding it. When it's closer to dry I think the alcohol trick would be a lot more successful but I haven't bothered since I'm going to be sanding everything. I also read someone say you can wait for it to "almost" harden and then shave it smooth with a sharp chisel putty knife as if it were hard cheese, but I haven't tried that. Once dry it's stronger than wood, though still possible to gouge with a fingernail and enough force. It sands at about the same rate as the wood around it. It cuts more easily than wood with a sharp knife and almost feels like very hard rubber as you're cutting. It also absorbs some stain - more stain than water-based Elmers - but it doesn't darken very much. Water will soak into it just like stain will, so it has some amount of porousness. But water won't disintegrate or weaken it - it didn't budge when a 1900psi pressure washer was placed a couple inches above it. Dried stain doesn't crack off of it like it does on Elmers. I also think PC Woody smells kind of nice, like wet wood, and it doesn't contain anything too toxic like the non-water based single-part fillers. The can warns that epoxy resin can irritate skin but I've gotten it on my fingers and had no reaction. It's also nice to be able to make a big batch and have an hour to work with it instead of trying to beat the clock with single-part fillers or having to keep popping open the single-part filler can and hammer it closed every time you remove a small amount. It also won't dry out when stored in the can for too many years like at least some single-part fillers. Since it contains real wood it hopefully will behave somewhat like real wood and expand/contract with the humidity so it won't crack away from what it's filling, but I have no idea if that's the case. I do know the few places I used it on the deck survived a winter and maybe 25 days covered in snow without any problem. I've read that Bondo (often recommended for outdoor wood repair if you paint over it to hide its odd color) is too hard and doesn't expand/contract so it can crack away from what it was used to repair over the years. As far as I can tell, PC Woody does not expand or contract at all as it dries or even a year later. One other important thing I noticed - there's one hardware store in our mountain community that all the contractors go to for supplies and I've noticed they seem to only carry the best brands due to lack of space. PC Woody is the only epoxy filler they carry so that must mean something. However, they have a much larger section of single-part Famowood in all sorts of tints. I actually found a can of Famowood that came with our house and the can looks really old but it still works. It's too dark for my purposes but I did a little test with it and it's pretty good other than I hate the acetone smell and it hardens too quickly. Didn't try it outside. Oh and the PC Woody can says it's made in the USA so that's a big plus. The second can of this filler I bought seems slightly thicker and harder to mix than the first can. It also seems slightly less sticky, which makes it slightly easier to smooth, but I worry it won't bond as well to the wood. I also found that it started to get unusably stiff and less sticky after only 15-20 minutes, much faster than the batch from the older can I'd been using immediately before opening the new can. I originally thought the second can was defective and curing too quickly, but I think the problem was actually that I mixed too much of it. From what I've read, if you mix a big blob of it, the heat of the curing process builds up more in the core of the blob and it hardens faster. I mixed a smaller batch and it stays workable longer. You can also spread a larger batch out as a thinner layer on a mixing surface instead of making a blob. I still feel like the second cans might be hardening a little faster than the first cans, but it's hard to be sure. Finally, this filler is really expensive compared to real wood. I thought the 48 oz cans would last forever, but I'm already running low for my project. When I got down to 1/3 a can left, I thought of mixing in chunks of real wood in amongst the epoxy filler in the larger voids. I tried using chunks left by a tree chipper machine but almost all had heavy damage to the wood. Since voids created by dryrot are long and somewhat triangular and fairly straight (as rot follows the grain), I cut 2" off the end of a 2x4 and used a chisel to break it up into small strips. Many strips were triangular and some square - a good mix. I then fit these into the rot pockets like a puzzle before epoxying. I lifted each wood chunk, laid epoxy paste under it, pressed it in, then filled in around and sometimes over it. Of course doing it that way takes a lot more time, but it does save a lot of filler. The filler was almost too hard to work before I finished with it, so remember to mix less than usual.

This stuff worked better than I expected it to. I used it on some rotted sections of my deck. In 24 hours it hardened up. I used a rasp, chisel, & razor to sand/shape it, then added a 2nd layer to some low spots. 24 hours later, it was ready to stain. Couldn’t have asked for a better outcome. I used their Wood Petrifier Hardner, 2 coats, beforehand.

Okay, so this stuff is awesome to use. I had woodpecker damage to wood siding, and about 200 holes to fill! Used this over a four day stretch, and these two tubs filled every hole (including extra to sand down). Make this stuff in small batches, as it takes about 30-45 min to start to set up. A full day to be able to sand it. You can stain it fairly soon after it starts to solidify- and be aware it does not absorb stain the same way as wood does, so it can take an extra coat or two. What I did was apply a stain two shades darker than I wanted with a tiny brush to just the wood epoxy spots- I did not wipe excess off but let it sink in. Then I covered both wood panels and spots with a semi-transparent polyurethane product to kind of blend it in. (It’s not perfect, but better!) In my pictures, you can see the one side where spots are darker and blend better- that’s where I applied extra stain to the fill product first; the pic with lighter spots was just the semi transparent stain/poly product on top. The paste itself was easy to use, just get an equal scoop of each tub and mix on a clean surface until color is uniform. You can get too much of one or the other and get a weird texture, so be careful that you get equal portions. I was applying this to holes in recessed areas so I used mostly fingers to shove it inside the woodpecker holes- I used disposable gloves because after the first trial batch I found it to be very sticky and tough to wash off my hands. Goo-gone did work but I thought gloves were a faster option. The material is sticky when mixed, a bit like room temperature peanut butter- so apply it in multiple directions if you need to fill holes or get an even surface. (If you are filling holes like I was, it saves product to use the gap-fill spray in foam stuff inside it first!) It did sand well where I sanded spots- by the end of my project I was too tired to sand the ones I ended up taking pictures of. It’s a never-ending battle with my neighborhood woodpeckers, so I expect more holes next visit. I just hope this stuff is bad tasting to birds hahahaha

I only wish we had purchased the larger size container. This product is similar to the Bondo brand putty, but it is two part putty,rather than one big putty container and a tiny tube of activator. So, it's easier to get the 1:1 mixture correctly. This means it will cure correctly. Easy peesy.

I was using this to fill check cracks in the wooden rails of my deck. I filled then sanded these cracks and I THOUGHT I was finished patching, but when I went back to stain/paint the rails after about a week, I found that the product had shrunk: EXACTLY WHAT I BOUGHT THIS PRODUCT TO AVOID. Before I used this, I had just used Bondo, which also shrank. PC-Woody SAID it wouldn't shrink, but it did, and I shoulda known it would because they don't guarantee results.

Having a few of the rainiest years where I live, it seems I am always repairing rotten wood around my home. Usually on my deck, window sills, or the base of exterior door frames. Initally I used the stuff from the big box stores with mixed results. It just didn't seem very durable. I have been using this for a year or so now with better results. It adheres to adjacent wood well, and seems very hard once dry, and stays that way. Paint seems to stick to it very well and it sands smoothly. Also, it is very thick so it does not run if you're patching a vertical surface. On the downside... Its pretty dang pricey.. I can't really fault it for this, but its also messy. By design, it sticks to basically everything and doesnt clean up well with water.. Just be aware to tape off places you dont want this. All and all seems a great product though. Lastly be careful to ensure it is mixed well. I got in a hurry and applied some of the white that didnt have much of the dark brown mixed in that good and ofcourse it never hardened and just became a sticky mess. Thats my fault, not the product, but be aware.. I tend to use old tupperware containers to mix it in and apply with a super cheap plastic spreader as cleaning tools or a container for re use are difficult with this.

Fácil de hacer la mezcla y usar , no pierde mucho volumen al secar y se lija bien .

this is a super good item. bonds well and is easy to use and sand and paint. but with confidence

Buen producto, muy práctico y resistente. Fácil de manejar y aplicar. Se puede trabajar como cualquier madera, una vez endurecido.

putty mixed ok and set hard in timber.
