How to Apply Air Seal Pro
Hand Brush- You can apply Air Seal Pro to any surface using a brush. In some cases, this might make more sense than gearing up for a spray job. We’ve created a specific product for hard-to-fill larger gaps called, Big Gap Brush-On.
Hand held Hopper- You can spray Air Seal Pro using a small hand-held hopper with air hose attached. It works just as well as the full machine set-up, however it is limited to the spray gun’s angle of use. The fluid will spill out of the hopper if tilted much more than 45 degrees up or down. It is also limited to volume capacity of hopper which is less than two gallons. It is a good option for touch-ups and limited angle requirements. This option also makes cleanup simple since you only have to clean up the small hopper and gun. Retail gun and hopper, under $100.
Graco 1400si RXT texture gun machine is an entry level spray machine. It is light weight (42lbs.) and its portability makes it a versatile machine. It’s noisy. It is limited by a maximum 25-foot hose, so you have to able to get the machine close to the air sealing. It’s small enough to fit through a 20”x24” hole so you can drag it up into some attics. But it’s 42” height may not fit into most crawlspaces. Retail about $1600
Graco 1500 RXT texture gun machine is a larger version of the 1400, with more power and can use a 50-foot hose and weighs 131 lbs. Retail about $3400
Benron Compact texture gun machine operates on a completely different kind of pump system. It’s a very quiet and very powerful machine. It is small, and at 70 pounds, lightweight (machine only). The Compact requires a separate compressor for air (pancake type at minimum— cost $100 and up). The Compact can deliver Air Seal Pro through a 100-foot hose, making it extremely versatile to get to any spray location while keeping the machine in one place. Its design is simple and its durable, the parts offer easy access and cleaning. This machine is all you will ever need for big or small jobs.
Benron sells a heavy duty commercial grade hose with their machine. I find it to be too rigid and heavy to haul around attics and tight spaces. I recommend using a commercial grade garden hose rated at 300-400 psi. The garden hose is also a lot cheaper and can be found online or at hardware stores. If you use the garden hose, tell Benron you will be doing so, and they will change out the machine to accept the 3/4” garden hose.
I have used 3/4” Gilmour Pro Commercial hose and 3/4” Never Kink Pro Commercial hose (Both are good, I prefer the Never Kink).

So, You are Ready to Spray: Using Your Texture Gun
Using the Benron Compact
Read Benron manual first.
Here is my view: It is very important to prime up the machine and hose and gun before you start spraying. First with water, then with soap. After you have followed all of Benron’s set up directions:
- At gun: Set air control at lowest setting.
- On pump control (box hanging on machine) Set material volume flow at #2 (lowest)
- To make material come out of gun, you must:
Turn on/pull up hand held switch. You must begin to spray once you have done this. Turn off switch when you stop spraying. Continue to spray for 20 seconds after turned off to relieve pressure in hose line (important).
If the material stops coming out of the gun shut off the hand held liquid delivery switch immediately (not the air). It is possible the granules are clogged either at the gun’s tip or where the hose enters the gun handle. Make sure the material flow or air is NOT on. Unscrew the nozzle tip and look inside the gun. Or, unscrew the hose connect at the gun to see if a clog exists. If yes: poke out the stuck cork and reassemble.
If neither gun nor hose end is clogged: disconnect hose from gun and turn on the on/off switch on the machine body, and see if the machine is pumping directly out of the end of the hose, (pump back into hopper) with no gun attached. If it is still not pumping, either the hose is clogged or the machine is not working properly. If the hose is clogged, you can use a 50 ft electrical wire puller to ream out the hose. This may not ever happen but It may be wise to keep an extra garden hose on hand.
Alternative start up: Follow all the steps above, but without gun attached, pump first flow of Air Seal Pro directly back into hopper. After material is flowing out of hose end, then attach gun to hose and begin spraying. This could prevent the granules from clogging at the hose or gun.
Using the Graco 1400 or 2000 RTX
Read the Graco manual first.
Here is my view: You might consider priming the pump and hose and gun with a soapy water 1:1 mix (not in manual).
If material stops flowing out of the gun, shut off the on/off switch on the machine body. It is possible the granules are clogged either at the gun’s tip or where the hose enters the gun handle. Make sure the material flow or air is NOT on. Unscrew the nozzle tip and look inside the gun. Or, unscrew the hose connect at the gun to see if clog exists. If yes: poke out the stuck cork and reassemble.
If neither gun nor hose end is clogged: disconnect hose from gun and turn on the on/off switch on the machine body, and see if the machine is pumping directly out of the end of the hose, (pump back into hopper). If it is still not pumping, either the hose is clogged or the machine is not working properly. If the hose is clogged, you can use a 50-foot electrical wire puller to ream out the hose.

Air Spraying Tips
Use a 3/16” inch orifice on the gun tip. You can go up to 1/4”.
Before you begin air sealing, test the gun on some scrap plastic or plywood to make sure you are getting the flow and spread you like.
I like to use stop/start pulling of the trigger to cover holes and cracks, and sometimes continuous spray for some applications. Experiment for yourself. Experiment with distance of gun nozzle as well as angle of attack and the volume and air delivery. The trick is to use as little material as possible to seal the gaps and holes. If you are winding up with big pools and lakes of material, reduce the air and or the volume delivery.
A second pass after the material sets up can reduce the amount of Air Seal Pro needed to close the gaps.
Too much air volume will blow the material off or away from the target.
Start the work at the furthest ends of the space and work your way back to the machine or access hole. That will save you from having to drag the hose and your body over already-wet areas (messy stuff).
If you are working up in an attic or a crawlspace, you are probably going to need a helper to be near the machine or assist with details that may arise.
Consider cutting a hole in the drywall ceiling or plywood floor to pass the gun through for access while leaving machine at floor.
Go back over already-wet areas and use a 4 inch brush for touch up.
