J-B Weld 40004 Wood Restore Repair Putty - 757mL

Material is super tough and versatile. A good choice.

Bought to repair some tongue and groove enclosed porch floor boards and was very skeptical. I cleaned out all the rotten places and drilled holes and added wood stabilizer really well and let dry for several days then mixed up small batches of JB. About a golf ball size scoop and streamed a heavy line across it with the hardener and mixed for a minute with a scraper and started filling the areas that needed filled. I continued until everything was like I wanted. It was so easy. And worked great. Now to sand and paint.

I barely had enough to do the job because the can is not shipped full. Looks like a lot more than what you actually get. Strong bond and cures quickly. East to sand and tool.

I have a covered patio that had some wood rot. I saw this on a Youtube video and it was so easy to use I thought I would try it. It works exactly like it should. I removed as much of the rotted wood I could and mixed the putty together with the small bit of the activator and it worked great. Drys really quick and I was able to sand it and paint over it. You would never know that it was rotted before!!!

Purchased this and the JB Weld 40007. I highly prefer this 40004 over the 40007 as far as both the combining/thoroughly mixing of the products for activation. I also experienced the 40004 applies much easier and creates a better bonding seal. Multiple surfaces were treated and prepped with the liquid JB wood restore and allowed to dry. In all of my experiences the 40004 was superior in every way. We prepared, applied, let dry, primed and painted and hope the product will last a long time to avoid having to replace some vinyl windows as whomever installed them did not get the tin close enough which allowed the surrounding wood to rot in places.

Does what it was intended to do. Fumes are pretty obnoxious while the catalyst is kicking. Used about 1/3 of the can in a 40' x 40' open area and could smell it all throughout the room. Use in a ventilated area only. Not enough harder to do the whole can unless you mix it so cold it takes an hour before you can file or sand. Pretty much on the same level as polyester body filler (Bondo)

This worked perfect after trying different types of wood filler/putty to fix a window that was cut snaller on one side. Pro tip -Use painter's tape where possible to make less mess and perfect lines and use a an electric sander. It sands right out with no problem.

Beware- this item is not returnable. I received this product in the form of a large can of putty and a small tube of hardener. The can had been opened and much of the putty was missing. The tube had been pierced on the end and much of the hardener was missing. Buy it locally so that you can inspect the packaging.
