What is the Handi-Foam E84 Class 1 spray foam kit?

A low pressure spray polyurethane foam with a two-component system made to fill and insulate large surfaces, creating a continuous air tight barrier. The quality of Handi-Foam E84 Class 1 completes the casing of the building, improving air quality and overall lowering heating and cooling cost.

Not only is this spray foam insulation kit high quality, easy to use and cost effective, it is also fire rated foam that meets multiple building code requirements for insulation, giving you the best for your dollars spent on any insulation.

The spray foam starts as two liquids that are heated and released through two hoses and combine at the tip of the spray gun, creating a foam spray that covers the targeted area evenly and expands to ensure an airtight layer when it sets up permanently.

Handi-Foam E84 Class 1 has a tack-free time of about 30-45 seconds and is able to be cleaned-up, cut, or scraped in a matter of 5 minutes, meaning you are able to cut, scrape, and mold the foam to fit exactly how you need it to, and where you are installing the insulation. This gives you the control you need to insulate any area in your home or building.

It cures within 1 hour of being installed. Due to the quick set time it is important to change the nozzle on the tip of the gun frequently. You should be change the nozzle after 30 seconds of non-use otherwise the foam will cure inside the nozzle.

While the installation of Handi-Foam E84 Class 1 is easy and manageable for any DIYer to do on their own, it is also important for anyone and everyone making use of the spray foam kit to wear protective gear during the installation process and to work smart. All polyurethane foam products contain strong chemicals that can cause sensitization from inhaling or from contact with skin. It is recommended to wear Personal Protective Equipment (PPE) such as, safety glasses, appropriate work clothes, gloves, and a mask or vapor respirator to avoid contact with said chemicals as much as possible. Your safety is ultimately up to you, so please be sure to follow the recommendations for protection.

How to Operate the Kit

Now that all the technicals have been covered we can move on to how installation starts and works. PLEASE READ ALL INSTRUCTIONS PROVIDED WITHIN THE KIT CAREFULLY.

You want to make sure the area you are spraying is clean of oil, dirt, water, and other liquids to ensure the foam is able to tack to the surface correctly. Next, you want to prep your spray tanks, one thing to keep in mind is not to let the tanks get too cold. The tanks should be at a temperature between 75 and 85 degrees to work, spray, and for the foam to be fully effective and tack to the targeted surface properly and safely.

It is recommended that the tanks be kept indoors or in a heated space. You may apply an appropriate heat source to the tanks before use, you may even set them in the sun for a couple hours in the summer time so that they can reach the correct temperature in order to spray correctly. The tanks will be warm to the touch when they are at the required temperature for foam to develop properly. It is recommended to warm the tanks 1-2 days before use making sure they reach that desired temperature.

Much like the tanks take time to warm up, they take time to cool down as well so unless it is 30 degrees and below where and when you are working, you do not need to keep a heat source on the tanks, they will not cool down in the time it takes to use up the entire kit.

NEVER apply an open flame to the tanks to warm them, a simple heating source works quite nicely. Be cautious and mindful and you will perform installation of the insulation like a professional.

After you have properly prepped the area and checked your tanks for the correct temperature, you want to give the liquid inside both of the tanks a good mixing. To do this, get the tanks on their side and rock back and forth aggressively for about 3 or 4 minutes each.

Once that is done attach the provided hoses. Do not over tighten the hoses to avoid breaking and the kit becoming unusable (some of the kits come with the hoses pre attached).

Once the hoses are in place you will attach a nozzle to the spray gun, it will simply snap into place.

You will find that each nozzle creates a different spray pattern:

  • The cone shaped tip provides a conical spray pattern that is ideal for overhead application
  • The fan shaped nozzle provides a wide vertical spray pattern that is more ideal for large area coverage.

As I already said, you should replace the nozzles after 30 seconds of non-use because of how quickly the foam sets and can cure inside the nozzle. But you are able to reuse them if they are cleaned properly with approved and suggested solvents. The nozzle tips are solvent resistant so using acetone to clean the tips is ideal. But cleaning must be done before the foam cures inside the nozzle tip.

Cleaning and reusing the tips more than once is not recommended, and remember to wear PPE while using the solvent to clean the tips and the gun.

With each of the tanks upright, the hoses attached and nozzles in place, open both of the tank’s valves completely and move on to spraying. You are going to want to “test” out the trigger by only squeezing ¼ to ½ the way to get a feel for the pressure and to achieve the desired spray pattern for your project. You want to be prepared to keep spraying in a timely manner, keep in mind that once the trigger is squeezed, it must be reactivated within 30 seconds of the initial spraying or the nozzle will need to be replaced or cleaned before using again. Failure to do this can result in the liquids within the tanks mixing incorrectly in the gun unevenly, chemical leaking, and ruining the hoses or gun completely.

DO NOT remove the hoses or clean with the solvent used to clean nozzle tips or the gun, this compromises the foam quality and potentially makes the foam not useable and unable to tack to the project surface.

Make sure you are spraying evenly and in 1-2” thick sections so that the foam layers and expands correctly, giving you the complete and air tight layer that you are aiming for. Trying to apply more than 2” in a single spray will pack the foam down preventing it from expanding properly, lowering its effectiveness.

As you work through your project, you may use up the kit completely or find that you have some of the product left over. There is a trigger lock on the spray gun that allows you to prevent accidental discharge of the foam, making it easier to save and reuse the product for another later project, just remember to clean the gun and remove the used nozzle to prevent damaging the hoses and the entire kit system making the kit unusable for future projects.
