Flexible Epoxy Wood Filler & Putty, 450ml Dual Cartridge, Cold | Cold weather 450ml dual cartridge epoxy wood filler; requires Dura-Fix gun, cures 40-70F for exterior wood rot & cracks

I didn't know what I was going to do. I tried some of the two-part putty mix from the big box stores. It sort of works, but it's hard to mix and very difficult to shape and place for anything but the smaller repairs. This stuff exceeding all my expectations, including the ability to put it on in 45 degrees! Mixes fast and easy, stiff and very workable, and cleans up easily with mineral spirits, even when partially hardened. I was able to mix and place three full tubes in this spot myself well within 30 minutes. Please ignore my messy technique. I ordered more to come around for another pass to clean up the top (it was too soft to really get clean in two dimensions. Holy SMOKES it's expensive, but nothing else is remotely like it. This is the happiest I've ever been about any home improvement product. I'm 100% keeping a tube of this on hand always now.

The product needs a special caulk gun (not just double barrel, but double barrel for a larger size) and I can’t buy one for less than $100. Return window has closed, so this was an expensive mistake.

The developer and owner of Next Generation Systems / Dura Fix is John Stahl. I spoke with John about the product before purchasing it. I bought two tubes of the cold weather formula and the application gun.Everything worked as advertised and I could not be more pleased with this product and its ability to repair wood in my old house that has rotted away and needs an epoxy to stick to the good wood and be able to sculpt it to match the original design.Once the epoxy dried, I just had to rough it up to paint it.Highly recommend this product.

Bought to rebuild rotten wood after treatment with hardener. Easy to use, but it rained on it overnight and it made a bit of a mess on the wall below. Cover it while it sets

Worked as required

This is a great product for use in the field.Normal epoxy resin is a liquid system requiring you to measure and mix either from a pump system or by volume.Product sets up extremely well giving you the right amount of working time.We use this to stabilize the substrate before adding our fillers from a different epoxy system.It has tenacious holding power and shear strength. Easy to apply and coat the deteriorated wood. It does not sand easy nor should it as there is no micro balloons or silica for sanding.The only downside is the case of product we ordered did not come with mixing tips this is the only reason for the 4 stars.We will order this again and hopefully for the price we can get the mixing tips or a link to order them
