Why is shipping only available via ground?
Spray polyurethane foam is classified as a hazardous material by the Department of Transportation due to being considered a flammable aerosol. As a result, our products can only be shipped via ground transportation.
Do you provide any additional discounts with bulk purchases?

What is the shelf life of Todol Foam products?
All aerosol products have a shelf life. Polyurethane foam products can range in shelf life from 9 months to two years.
Shelf life is dependent on the valve system that is being used. We use predominately the Pageris Valve. This is the highest quality valve on the market. It is made with only plastic and metal components, thereby eliminating any storage issues.
Most other foams use a rubber valve system. These rubber valves expand and contract while in storage due to temperature fluctuations which then can allow the propellant to escape the can and ruin the foam.
Our plastic and metal valve does not expand or contract with weather fluctuations. For the best storage, store our cans of foam in an upright position in a dry constantly moderate temperature.

Can you provide the Safety Data Sheets (SDS) for your products?
Where can I find information on best safety practices for using spray polyurethane foam?
Does the foam present a hazard to workers?
One of the chemicals in all urethanes is a dilsocyanate which can cause irritation to mucous membranes if present in high concentration. Our foams are designed to reduce this hazard, and in fact tests have shown that in normal use irritating levels of diisocyanate are never reached.
Do the foams contain formaldehyde?
No. They contain no formaldehyde and cured urethane gives off no odors.
Does the foam burn?
Yes. The foam is combustible, self-extinguishing, has low flame spread and does not drip.
Tips & Tricks
What is the most important thing to keep in mind when using this system?
ALWAYS KEEP A CAN ON THE GUN. The pressure of the aerosol can prevents moisture from entering the gun.
What happens to the gun if the can is removed and not replaced?
The gun will become locked with cured foam. The foam will cure in the gun and there is no solvent or cleaner that will remove the cured foam. In this case, a gun replacement would NOT be covered under warranty.
Do I need to use a gun cleaner?
We believe if you “ALWAYS LEAVE A CAN ON THE GUN AND PULL THE TRIGGER ON A REGULAR MONTHLY BASIS” there shouldn’t be the need to purchase gun cleaner.
The common gun cleaner is acetone, commonly known for being finger nail polish remover. Acetone breaks down the propellant collapsing the polyurethane into a thicker polyurethane resin. The cleaner then pushes the resin through the gun. The use of cleaner is time consuming, expensive and can lead to the polyurethane to coat the inside of the dispensing gun.
Always have a can of foam on the gun; it doesn’t matter if the can is empty or full.
What do I do if the can on the gun is empty and I do not have a replacement can available?
Leave the empty can on the gun until you have the replacement can. Even an empty can has enough pressure to keep air out of the system and this will protect the gun from damage.
How do I change cans?
Remove the empty can, promptly screw on a replacement can and continue foaming. If there is to be a delay before foaming, purge the system for a few seconds after the new can is in place.

What do I do when I am through foaming?
Lock the flow adjustment screw at the back of the gun to prevent accidental discharge of the foam. Thoroughly wipe the tip of the dispensing gun to remove any uncured foam.
How long can I leave a can of foam on the gun?
The foam when properly mounted on the gun will be usable for the full shelf life of the can. We have seen cases where cans have lasted longer than 2 years and still worked when needed.
What do I do if a properly mounted can on the gun either doesn’t dispense or the stream is very weak?
A) First assure that all cured foam has been removed from the opening in front of the needle valve at the tip of the gun. This is the most common problem. B) The second most common fixable complaint is a sticky ball valve. This has the same symptoms as the first, but a different cure. Unscrew the can from the gun and immediately flush the valve and the adaptor with Pur Clean. Now pull the trigger to reduce the pressure in the gun; this will dispense a little foam, so do this into a waste basket. Now look down into the adaptor to locate the white or green ball valve. Use a pencil to push the ball down into the gun. This will free it up. Screw the can of foam back into the
adaptor.
How does the foam cure?
The foam cures by reacting with water. While beads less than 1″ in diameter can get all the moisture that is required from the air, the best technique is to spritz a mist of water in the place where foam will be used. This assures a faster cure and full expansion of the foam to its maximum volume.
What is the proper technique for using the foam and gun?
Shake the can before each use, hold the can vertical while dispensing and keep the tip of the dispensing tube clear of cured foam. Increase the flow of foam by backing off the flow adjustment screw Do this carefully, there is no stop on screw.
Can I make any size bead?
All sizes from 1/4″ to 2″ are easily made directly from the Pageris gun. Needle adaptors which press onto the nub at the front of the IPM gun can make much smaller beads. Use an adaptor when the end of the gun is too large to fit into the gap which must be foamed.
Flexible tubing, which fits on the nub, permits foaming around corners or behind pipes.
Rigid, longer tubing which fits over the end of the gun dispenser is also available to extend the reach when the place to be foamed is beyond the length of the gun.
Can I make a thick section of foam?
Yes. If a very thick block of foam is needed, we recommend that you lay in a 1 inch bead of foam and then mist water on top of the uncured foam; Do not put water on the top layer of foam, use this layering technique until the cavity is about half filled, the expansion of the foam will complete the filling.
How long does it take for the foam to cure?
The surface will be tack free in about 10-15 minutes, and is trimmable in about 40 minutes.
Can the foam be used at low temperatures?
It can be, but best results are had when the can temperature is at least 60 F Lower temperatures slow the flow of the foam and job takes longer. The surface to which the foam is applied should be above freezing.
How do I remove foam that is in the wrong place?
Pur Clean will dissolve the foam, as will lacquer thinner, but solvents still leave a mess. It is best to mask the work area to prevent problems. Cured foam is removed with sand paper.
What effects cured foam?
Direct sunlight will slowly destroy the foam, but a coat of paint will protect it perfectly; either oil or latex paints will work. The foam does not shrink nor become brittle with age. It is not affected by water, or most solvents.
Will cured foam stop the passage of gas, air or water?
Yes. Closed cell foams expand in place and bond to most construction materials to effectively seal the opening.
Will new foam bond to old foam?
Yes. Just be sure that the surface of the old foam is clean.
Are there tips for foaming around doors and windows?
One component moisture curing polyurethane gun dispensed foam is an excellent product to use around windows and doors to stop the passage of air.
Goal: To stop the passage of air and drafts. Purfill WF has excellent adhesion and adheres to most window materials.
We are air sealing, not insulating. With insulation more is better, but this is not true when air sealing around windows and doors. When foaming around windows and doors the goal is to match the thermal resistance factor (R-factor) of the window. Most windows have an R-factor of 2 to 3. Purfill WF has an R-factor of about 5 per inch. Therefore ¾ of an inch of foam should be sufficient to match the R-Factor of the window.
Place the foam as close to the exterior as possible. Then follow these simple instructions:
- Shake the can very well
- Assure the can temperature is between 60-80 degrees F.
- Practice laying down beads of foam. Play with the set screw on the foam gun and leave the setting when the desired bead size is dispensed.
- Assure the window is clean and dry to assure good adhesion
- Foam from top to bottom, placing the foam gun barrel into the void and foam down the window
- For small voids, use our foam reducer or plastic barrel with the green needle; dispense the foam slowly when using these adapters.
- When foaming is complete, let the foam properly cure, review the window and look for any void and use the foam to touch up where needed.
