Topic tags/keywords: veneering spray gun question

This is less for fun, and more for work. I have found myself needing to relaminate millwork in certain remodeling jobs over the past couple years. I have learned as I go, and gained knowledge through research. Basically, I have been using rollers to apply adhesive onto the substrate.

It occurs to me that in a production environment, the more efficient apparatus for applying glue would be a sprayer. Each of my relaminating jobs has been such that work is performed in the field, and not in a shop environment.

I wonder if anyone here has had experience with spraying glue in a similar manner as paint, using compressed air, for instance.

You have posted in the right place. Spraying contact glues is the only way to go, with few exceptions. Come to think of it, I can’t think of any exceptions ! for 20 or so years I used two gallon paint pots with binks guns with 16-20 ft. Hoses. with this style we typically used lock weld red. For the past ten yrs. I have been using teac canisters which come in asstd. sizes. An 11lb can for example is very compact and travels well. Also it is a single hose system which is convieniant. I personally prefer the green glue as opposed to their clear as it is very easy to see. Once you have the hose and gun you only need to buy canisters as needed. I have found that I can get approx. 400 sq ft of coverage with an eleven pound bottle.
If you have any other questions about the spraying or anything laminate, ask away. JB

I have no experience spraying glue but it seems that masking off the horizontal area for a typical laminate job could take more time to do than just rolling it out,my guess in an average kitchen you might need 20-25 minuets to roll it out where spraying it you might take 5 minutes to shoot plus gun cleaning 15 minuets and masking 10- 20 minuets. The coverage with spraying must be very good as it is with any job you spray,assuming you have experience spraying. Then the main advantage of spraying is good coverage verses rolling (assuming my estimates are correct for spraying ,clean up and masking are correct) rolling is quicker,with less equipment clean up. The folks who do this all the time must feel spraying is a better way to go if they spray.

Been using spray canisters for contact for the last 15 years. I’m never going back.

Awesome info guys. Thanks!

I wonder also if th glue requires thinning, and if the nozzle tends to get caked up. I assume cleaning with minerals spirits, or acetone would be required.

I’m going to research the gun types you mention. I have found that buying the right tool for the job tends to pay for itself in man hours in virtually no time.

With a little experience/practice masking or use a piece of cardboard to protect areas you don’t want glue is quite fast.

One of the great thing about the spraying with he canisters is you never have to clean the gun, the hose or anything other than wiping the tip of the gun occasionally. Once you hook the hose to the canister and pressurize it you never turn it off until you change to another canister. The canisters can sit around for month at a time not being used and are ready to go when you are. Great system.

There it is, alaskaguy… I had a misconception, but a YouTube is worth a thousand words. I was thinking air compressor and a gun with a can attached. This is a thousand times more efficient. My current job is restroom partitions, so masking is a non issue.

Another question comes to mind: does the hose become clogged with glue… And how do you prevent/address that issue?

If you’re using contact cement…..
I’ve worked in shops that sprayed almost everything, except for very small work where we used brushes. The pink adhesive came in 55 gallon drums, and we would use regular pressure paint guns. cleaning up was easy, in fact we’d often let the spray heads stay immersed in laquer thinner overnite, and the next day we’d just pick up where we left off. Super fast, easy, and super-even coats. Our ‘easel’, a 4X8 sheet of particle board, where we’d spray doors and panels, was about 3 inches thick with old overspray.

I actually have a five gallon can of contact cement. I bought it when I bought the laminate. (From wilsonart) I probably overpaid, but convenience is sometimes worth a premium.

Could I use the air compressor and pain sprayer I already have? Would I need to thin it?

I wish I had asked earlier, because the method in the YouTube video is very efficient and manageable in the field. Not tied to a compressor, or limited to a quart sized spray can. 400 square feet of straight production.

It might even be worth taking my 5 gallons back and buying two or three 11 pound canisters and the spray nozzle. It could save perhaps 5 man hours on this job alone.

Cardboard is in abundance… That will come in handy.

One more question, if you guys don’t mind…

Where does one purchase these pressurized glue canisters, and does a standard paint nozzle do the job?

I found a couple sources by opening a snack size package of google, but the two sites I actually found seemed to be distributorships. I’d love to pick this up locally.

AlaskaGuy nailed it.
The canister style in the youtube vid is the only way to go!

Super efficient, pretty much zero maintenance, really easy to use, low odor and the glue sets up in less than 5 minutes, usually 2 or three.
As for taping off, the speed, ease of use, zero maintenance and quick set up more than makes up for the time it takes to tape.

Buckethead
Contact(pun intended) the distributor. They’ll tell you where to get it.
As for the paint nozzle, no idea as I’ve never tried it. I would guess no though.

I am convinced! Now I just need to find here to purchase locally. I usually have good luck with google, but this seems to be a specialty item.

Glenseal
CP adhesives.

All online, but none with simple shopping. I’ll need to have it in hand by Wednesday the 8th. So if I can locate it, that is definitely the route I will take.

I would think unless your way out in the sticks your laminate dealer should be able to hook you up.

Very valid comment. I live near Jacksonville and Saint Augustine, Florida in Ponte Vedra Beach. I went to wilsonart, the laminate manufacturer (the jacksonville distributorship) and the guy seemed fairly clueless as it pertains to installation of his product. They had contact cement, and a j roller, and that was it. I asked him about a slitter, and he had no idea what it was.

I’m sure I can find another source Monday. I also need to supplement the existing partition hardware with a few replacement pieces, but I have a source for that.

Again, thanks for all the tips. A no cleanup, minimal set time, portable, labor efficient means of increasing my income was just handed to me on a silver platter. I am truly grateful for all those who commented. Very glad I joined this forum.

I did want to add that the gentleman who helped me at wilsonart did go above and beyond the call of duty and was able to obtain very favorable pricing for their product. I don’t want to throw him under the bus with my previous comment. He was a great help.
