Technical Spraying Upholstery Adhesive question

So I am getting ready to make some door panels for my 39 ford in an effort to make a more comfortable trip out to Bonneville in a few weeks. I have my panel boards, upholstery materials everything i need to do just like i have done in the past with one exception. I have always used the Spray glues in a can in the past, and have always been less than impressed with both the quality and the cost of the cans. This time around i have a gallon of spray grade Dap Weldwood.

I used Weldwood when i covered the running boards with white vinyl and it worked great. But when i did that i used a brush which was messy and tough to get smoothed out. This time around i would like to spray it on. So he is the question, after searching I have found tons of different answers, but would like to hear from guys on the HAMB what they have used with success as far as thinning the contact cement to be sprayed and what type of spray gun you used to spray it with. Its certainly cheaper to do it by the gallon and spray it than buying a bunch of cans at 20 to 30 dollars each.

 

Go buy a cheap spray gun. One from Harbor Freight will work just fine. Or use an old wore out paint gun. Weldwood from the hardware store. The glue isn`t as thick as the commercial grade from an upholstery wholesaler. So when shooting thru the gun--- it sometimes shoots little glue bubbles. Adjusting the pressure doesn`t work to prevent this. It also takes longer to set up. So maybe try leaving the glue exposed to the elements to see if this helps. To thicken it up a bit. I only use the hardware store kind when I`m in a pinch.

 

Here's a great video that will answer your questions.
It looks like a Harbor freight gun was used.

 

I've been using 3M # 45 spray adhesive (aerosol can). The local ACE hardware has it for 8 or 9 bucks.

Cheap Harbor freight spray gun.

 

I just used an old siphon feed paint gun with the tip drilled out. Didn't need to thin the glue.

 

Economically priced gun with a 1.8 tip works great. We don't thin it out. Clean up with mineral spirits. I use the sprayway 92 in the cans. It's really good stuff. I get 10 cans for a little over $100. If you're going with pleats of any kind on your panels, concentrate your glue on the back side of the seam, and when your go to rub it down, use your scissor handles and rub the seam down first. Makes the pleats look more full.

 

Great tip to make the pleats look more full.

 

Thanks for the tips guys. I was planning on picking up a cheap siphon feed spray gun with a large tip at harbor freight to do this with. Do not want to risk any of my good spray guns.
