The VOC’s will still linger. I would get in contact with a commercial hvac company and get them to put in an air exchanger that should cycle out all the air.

I use Camie adhesive on most of my work. I still use a respirator, but Camie is non-flammable and doesn’t put off near as much fumes as Weldwood. It’s properties are a little different, but I feel it’s a little less hazardous and works well for me. Also, I have a separate sewing room from where I spray glue that has an air purifier. Maybe a couple of ideas that will help your situation…

You could look into using Simalfa745 glue. It is water-based versus Weldwood which is a solvent-based glue. I still use Weldwood for certain things including headliners, which I do outside, but Simalfa works really well for most things. You can contact Jay for questions. Phone number: 973.423.9266 x122

How did the 321 work for you overall as an adhesive? I have a full box that I have not started using yet.

As an adhesive, it works great! I've used it for a couple of dashboards and headliners. It is different to work with than Weldwood. So, there is a bit of a learning curve as you understand how to work with it. Each glue has its advantages and drawbacks. On the headliners, it bled through a little bit. It ended up being in an inconspicuous area so it wasn't a big deal. I'm guessing since it is water-based it bled through a little easier; I probably sprayed a little too heavy in those areas.

I mainly use it for gluing vinyl to scrim and repairing foam. I like that you can attach the pieces right away instead of waiting for the glue to dry a bit as you do with Weldwood. Saves a few minutes of time.

I can't say that Weldwood is better or Simalfa is better, they are different. It is nice to have another tool in the arsenal depending on what I am doing. \

I have to say the foam to foam bonding is amazing! I am experimenting with it right now seems to take a bit to dry maybe coating too much. I do have a question though. Did you go with their gravity system and their spray gun or put the solution in you own pot?

I went with their gravity system and their gun. It works really great.

Fantastic! I have it all set up just a repair on my gun to do then am on my way to experimenting with the 321. I never seen the 745 maybe that would be the box to buy next?

Thank you

I believe 745 and 321 are the same. Not 100% sure though.
