I'm planning on refinishing the concrete sidewalk to my front door and was told by a friend in the concrete business that I should purchase WeldBond glue to assure good adhesion between the layers. I purchased a gallon of the glue and was amazed at its claims. I went on the net to see what I could find on it and came up with some really interesting info. Woodworking sites seem to like it. It is recommended on a few mosaic/tile sites as a sealer and adhesive. I found it highly recommended on two separate model building sites as an excellent adhesive for wood and foam - claims that the wood will break before the bond. One site even recommended using it with fiberglass cloth instead of epoxy resins - claimed it dries to a glass like finish and is paintable, sandable and toolable. It can be used as a primer for paint and is an excellent stain blocker. It has been used by NASA, can be added to colored concrete to use as a paint on finish, can be used as a sealer or crystal clear finish, wont peel or crack, glues glass, metal, terra cotta, wood, foam etc, etc, etc. REALLY! Well we'll see about that. I plan to try it on HDU, Cedar, Concrete, mixed with concrete as a stucco, as a base for gilding, to glue metals & glass together, as a clear coat, put it in the sun and then throw it in the freezer. Anybody tried this stuff - it has been around since the 60's? Anyone want me to try it out on any applications while I'm at it?

Hey Kelly, I wonder if that would be good to use to apply zip-change copy tracs to plex, lexan and white baked-on finish aluminum? Sounds like you are the "consumer Reports" person on this one! By the way how do you apply it/ how does it come? (ex. caulk tube, can, bottle, etc.)

So far I have tried it on HDU to prepare it for gilding - I haven't tried the gilding yet but it is alot nicer than primer. I watered down the first 2 coats 1 to 5 and then applied a 50-50 coat. What I liked about it was that the first coat took care of the crumbs and it made a glass like finish. I also glued some glass stones onto a piece of glass and stuck pretty good. The glue dries clear so you can almost imbed the stones in it. Next week I have to do a repaint on a sign so I'm going to try using it as a primer first. It claims that it will penetrate the old paint and bond to the new paint acting as a sealer and primer. I'm going to tell the client that because I don't know who painted the original that I can't guarantee anything. The nice thing about using it as a primer is that it dries clear so I'll be able to see the original. I'll let you know how it works - hopefully I won't be posting a replica of your post Karyn. LOL Sheila the glue looks similar to white craft glue. I brushed the diluted stuff on with a foam brush and for the glass I applied it from a squeeze bottle.

Hi there,
I used WeldBond on nine 2' x 3'sandblasted signs for the back nine at a golf course here. I dropped a coulpe of scrap pieces from waste height and, sure enough, the wood (delicate cedar) cracked and the glue seem stayed intact. I know Gorilla Glue is "DA' CHIT" but I like the tried and true appeal about Weld bond......if it has been on the market for..ever (like comet) then it must have proven it's worth. I did the signs just before Winter and gave them to the course for storage. They were put up last week and I will be golfing this Sunday to see them "hard at work". If there is any glue issues, I'll fill you in.....no punn intended...well, a little.

Does Weldbond have to be ordered or do any stores carry it? I would love to try some. I just need to know where to get it. Thanks

Kelly, for guilding on HDU, try DuraFinish from SignFoam. It is a 2 part epoxy that is very fast and easy to apply. It will self level and end up as smooth as glass. Add a little One Shot metalic gold to the epoxy (the ratio is in the instructions)for a base color. 24 hours after you apply the epoxy, you're ready to put down the size.
It's also a bonding epoxy. Will make HDU stick to almost anything.
