Q. What is the difference between One-Component foam and Two-Component foam?

A. One-Component foam comes in a single can (or cylinder) and cures in 10 to 20 minutes through a reaction with moisture in the atmosphere. Two-Component foam comes in a kit with two cans (or cylinders), each containing a separate chemical. Upon activation of the kit, the chemicals are mixed and dispensed through a specialized dispensing unit. The cure time is much shorter than One-Component foams, usually within two minutes.

Q. What is the cure time for Handi-Foam® Two-Component Foam?

A. Handi-Foam® Two-Component Kit Foam is a chemically cured polyurethane foam sealant. The cure time for Two Component foam is very short, within 2 minutes foam will be tack-free and chemically inert. Two-Component foam is cuttable in 2-5 minutes and is completely cured in 1 hr.

Top

Q. What is the best temperature for using Handi-Foam?

A. Handi-Foam® should be applied when the temperature of the tank contents is between 75 and 85 degrees F. If the tank or can is warm to the touch then it will dispense properly. It is important to remember that the contents of the tanks will take some time to warm up completely. This is a non-issue on a warm summer day. But in winter if the tanks have been stored in an unheated area it may take a considerable time to be certain the actual contents have warmed up. In these cases please plan ahead so that you can allow adequate time for the contents to warm fully.

Warning: Foam containers should not be stored at temps in excess of 120 deg F or stored in direct sunlight. Two Component Cured foam should not be exposed to flame or temps in excess of 240 deg F. One Component cured foam should not be exposed to flame or temps in excess of 200 deg F.

Top

Q. Some Handi-Foam® items are classified as E-84 Class1, what does this mean?

A. ASTM E-84 Class 1 is a rating indicating a material is fire rated product. When a flame-retarded material passes a specified flammability test, it is termed a fire rated product. In practical terms, a fire rated product aids in reducing the risk of flashover in a major fire by its diminished role on supporting combustion. However, being organic in nature, fire rated products are still combustible. Even the most flame retarded urethane foam will undergo combustion at temperatures exceeding 1022°F (550°C).

Q. Does Foam off-gas once cured?

A. No Polyurethane foam is completely inert once cured. There is no off-gassing.

Top

Q. Do I need to buy a dispensing gun and hoses for my Two-Component Handi-Foam® kit?

A. No you do not, all the accessories needed are supplied in the foam kit. This includes factory attached hoses and a dispensing gun. The hose length is 9-1/2 ft. The larger II-600 and II-605 kits come with 15’ hoses. All kits come with 8 disposable nozzles (5 Cone and 3 Fan Nozzles).

Top

Q. Do Handi-Foam® products have a VOC content?

A. No. One of the great benefits of all Handi-Foam® Two Component products is that they are 100% free of VOC's.

Top

Q. Can fungus or mold grow on Handifoam in damp conditions?

A. Foam does not support the growth of mold or fungus.

Top

Q. Can Handi-Foam® Slow Rise be used in pool/spa applications?

A. Handi-Foam® SR is commonly used in this application to fill a void under a tub to stop flexing, provide structural support, insulate and reduce vibration. However, installers should be aware that the foam will expand at least 3 to 5 times and exert a lot of pressure on the tub. Use a brace to secure the tub/spa or fill the tub with water to add weight to keep the tub in place when foam is rising and curing.

Top

Q. Can Handi-Foam® or Handi-Stick® products be stored?

A. Yes. Instructions are listed below for the different types of products:

One-Component straw foam - Leave straw adapter connected to aerosol can. Trim off tip of straw to reuse. Product must be reused within 30 days.

One-Component gun foam - Leave pressurized can of foam attached to gun during storage. Product must be reused within 30 days.

Two-Component foam kits - For short or long term storage please follow these guidelines:

  1. Leave dispensing gun and hoses attached to cylinders.
  2. Always remove and discard the used gun nozzle. Never attempt to dispense material through a nozzle that has been left unused for more than 45 seconds! Doing so will ruin the Gun and Hose assembly.
  3. To avoid discharging material after removal of nozzle set the black trigger safety in the down position.
  4. Use the supplied tube of petroleum jelly and a rag to clean the tip of Handi-Gun® where disposable nozzles are mounted. After you have finished cleaning the mounting face apply additional petroleum jelly to seal out moisture and prevent corrosion during storage.
  5. Cylinder valves should be turned off; however, do not drain hoses.
  6. For long-term storage fresh chemical should be dispensed through the dispensing gun every 5 to 7 days to avoid crystallization within the hoses. No more than 1 foot of material needs to be dispensed to accomplish this. It is not necessary to mount a nozzle on the Handi-Gun® when performing this operation.

When you are ready to begin using your Two-Component foam kit follow these guidelines:

  1. Be certain contents of foam containers are warm (75 to 85 Deg. F). A rule of thumb is if the tanks exterior is somewhat warm to the touch (and the tanks have been stored in a warm area) then the contents are warm enough to work properly.
  2. Agitate the contents of both tanks. Gently rock each tank back and forth for 1 minute or so to ensure that the contents are thoroughly mixed and have not settled in the bottom of the tanks.
  3. Inspect the face of the Handi-Gun® for dirt and debris. After ensuring that it is clean put a layer of petroleum jelly on the mounting face and attach a new nozzle to the Handi-Gun.
  4. Open the valves on the top of each tank (turn them counter clockwise ) and release the trigger safety on the Handi-Gun.
  5. Once you are ready to begin spraying foam fire a test shot of material into a disposable container. This will ensure that the material is mixing and dispensing correctly. If everything appears normal begin spraying foam immediately. If the Handi-Gun® is un-used for more than a minute you will have to replace the nozzle before using tool again.
  6. Always wear eye and skin protection when spraying foam. Refer to manufacturers complete instructions supplied with kit before use.

Q. Can Handi-Foam® be used as a Fire Stop?

A. No, Handi-Foam® is not rated for Firestopping applications. Handi-Foam® E84 Class 1 foams are classified as flame retardent. This may include insulating rim joists, tub and spa applications, use in mechanical rooms near machinery and in vehicles and refrigerated trucks. Cured foam should not be exposed to flame or temps in excess of 200 deg for one component foam and 240 F for two component foam.

Standard and Handi-Flow® Two-Component Handi-Foam® kits are not classified as fire retardent.

Top

Q. Can Handi-Foam® be used as a Flotation material?

A. Yes it can. Handi-Foam® meets the U.S.Coast Guard Spec. for flotation in Title 33 Code of Federal Regulations, Paragraph 183.114. We recommend the use of Handi-Foam® Slow Rise for a more controlled application. Also keep in mind that large volumes of foam in a confined space can generate heat while curing. Use caution when touching a metal pontoon or canister until it cools. Handi-Foam® exposed to UV rays must be painted to avoid the hardened foam being damaged by sunlight.

Top

Q. Can Handi-Foam® be exposed to sunlight?

A. Polyurethane based foams are sensitive to UV light ( Sunlight ). Any UV exposure indoors or out will cause the foam to break down. If used in an area exposed to UV the foam must be painted to provide UV protection. However it will work very well in an outdoor application as long as it is coated.

Top

Q. How can I remove foam from surfaces?

A. Since no solvent readily removes cured foam, it normally must be removed through mechanical abrasion techniques such as scraping or sanding. Uncured foam can be removed with Handi-Foam® Cleaner, acetone, or nail polish remover.

Top

Q. How do I determine the amount of foam coverage in a Two-Component kit?

A. The Foam kits are identified by a number. For example a II-205 kit will yield 205 board feet of dispensed and cured foam. A board foot is defined as a 12” x 12” square x 1” thick after expansion and cure.

Top

Q. How do I dispose of a Two-Component kit once I am done with it?

A. Relieve pressure from the cylinders by fully dispensing the kit. Dispose of kit per local regulatory guidelines. Please read complete instructions supplied with your kit.

Top

Q. If I want to fill a mold or cavity, what type of product should I purchase, and how much will I need?

Q. To which surfaces will Handi-Stick® adhesives bond?

A. Handi-Stick® Adhesive Polyurethane Foam will stick tenaciously to a wide variety of substrates, including metal, plastic, rubber, brick, concrete, drywall, glass and wood.

Top

Q. If I spray a Two-Component kit, and the foam does not cure, is soft and spongy, or is crispy to the touch, what went wrong?

A. The kit is probably off-ratio. The components are designed to dispense 1:1 in volume. Make sure the kit has been thoroughly shaken before use, and that each tank valve is fully open. Change the gun nozzle and resume spraying. Proper chemical temperature is also required for optimum dispensing.

Top


Q. How many disposable nozzles will I receive with my Two-Component kit?

A. Each Two-Component kit, size II-105 and larger, will come with 8 disposable nozzles. Regular and E-84 foam kits will come with 5 Cone and 3 Fan style nozzles. The Slow Rise foam kits, designed for filling large voids and cavities, will come with 8 Cone style nozzles. Additional nozzles of either type are available in our on-line store.

Our small II-15 Two-Component kit is supplied with 2 disposable dual purpose style nozzles.

Top

Q. What is the difference between Cone & Fan Nozzles?

A. Cone Nozzles are designed to dispense Two-Component foam in a steady stream. This makes Cone nozzles ideal for filling closed wall cavities, large voids and for filling drums and pontoons used for flotation. Fan nozzles have a flattened tip and dispense the foam in a fan type spray pattern. Fan nozzles are best for use when spraying foam over larger open area surfaces such as walls and between floor and ceiling joists.
