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

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.

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!!!

Be very careful with the stuff. It dries extremely hard which is a positive as long as you don’t goop on too much initially. Sandpaper does not work you really need a file or hasp to get off excess. Very good adhesion to existing wood.

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.

Great product

Product arrived damaged, and there is apparently a second component called a hardener that it has to be used with. I didn’t open the container in case the contents had been exposed from the dent where the lid meets the can. I decided to use a different product. When I went to return it, I saw that it was not returnable or refundable, so I’m out $26.

Bought at the request of my partner. He said it worked perfectly. It was easy to mix, use and apply. It’s now all sanded down and ready for paint. He still has quite a bit a bit leftover in case we need it for another project.

This works well (and got the job done) but is just body filler with white hardener instead of red or blue. smells a lot worse that any wood filler that I know of.
