System Three 1610K20 Brown SculpWood Paste Kit, 0.5 gal Tubs

Love the Sculpwood/Endrot rot repair series - from the Borate solution, via the Endroot fluid epoxy, to the Sculpwood paste and putty epoxies. I've used tons of the stuff for patching up sidings, railings, deck beams etc. The paste is best for filling small cracks or tweaking your results once you've filled a bigger void with the putty variant and found imperfections with your job after some sanding. The stuff is not "elastic", so it's not recommended for filling gaps between moving parts such as railing tops hitting posts etc. Sculpwood was originally recommended to me by a seasoned painting expert in Napa CA, and I've never looked back.

You can buy the putty consistency epoxy wood repair all over the internet and some stores. This stuff is different and has been hard for me to find. Consistency is in between liquid resin and putty. The consistency of the resin part is like cake icing and the hardener is like a thick pancake or cake batter. When mixed the final product is somewhat between the two but as hard as any other wood fill epoxy when cured. Working time is similar to putty formulations out there. If there is a better product for skimming or filling grain for a mirror smooth durable wood surface (like a piano surface) on a vertical or overhead surface I haven’t found it. I’ve found that having liquid, this stuff and putty epoxy on hand has been invaluable in restoration and wood repair.Finally, don’t complain if you didn’t read the description of what you were buying. People that do that and wrongly drive down product ratings should be banned from giving reviews.

A few years ago I hired a "pro" to fix some rotting decorative columns in front of my house. He patched them with Bondo but didn't fix the source of the water leakage nor did he kill off the fungal infection so it all came back. I tore it apart and, using System Three's RotFix, Paste, and borate products, I patched it up. I ran out of the Sculpwood Putty and ordered more but accidentally bought Sculpwood Paste which is really a thick syrup, not a paste. It turns out to be perfect for filling cracks up to about 3/16" of an inch, something that the putty won't do well at all.Everything is sealed up tight now, even the tiniest of cracks; I doubt I'll have water problems again.

Mix equal parts of A and B and get a first class epoxy for filling cracks, knot holes and rot in wood. Just finished painting my house and this product worked great. Be sure to thoroughly mix the two parts and apply. When using on a vertical surface I let it set up for about 20 minutes on a cool day, less on a warm day and it filled counter sunk screw holes, knot holes and cracks in the wood. I let it dry for two days and then painted the wood to protect the repair, The epoxy does not appear to be U.V. stable. A+ product

I use it like spackle for exterior trim. It works well for weathered wood, if you are remiss in your facia upkeep. :( Mix only what you can use in 15 minutes, less if it is hot.
