Foam it Green Slow Rise Spray Foam for Filling Closed Walls

Customer Top 10 Questions & Answers

Why is Foam it Green Slow Rise the best choice for my home?

Foam it Green Slow Rise is the ONLY Slow Rise formula on the market that is an ASTM E84 Class 1 fire retardant insulation, so it’s safe to be in your home. It is also the only ASTM G21 Anti-Microbial Slow Rise insulation on the market. Finally, it is the only Slow Rise with the blue-and-yellow-makes-green technology, so you know you’re putting foam that will cure into your closed walls.

Can I use Slow Rise if I have fiberglass batt already in the wall?

Foam it Green Slow Rise is designed to work only on empty vertical walls. If you wish to blind-fill a wall that already has fiberglass batt, look to our unique product to solve this, the DROPFILL system.

Can I just drill one hole at the top to fill the whole wall?

The best way to fill an existing vertical wall with Foam it Green Slow Rise is to drill a hole every 3′-4′ up the wall. By going slowly in chunks, you’re increasing the likelihood of getting a complete tight air seal, and reducing the risk of bowing or blowing out the drywall. It is not recommended to do it from one hole at the top.

Can I blind-fill an existing cathedral ceiling or horizontal surface?

Foam it Green Slow Rise should be used to blind-fill only vertical walls. The slow rise project of drilling holes every 3′-4′ should not be performed on slanted or horizontal ceilings or floors because it is very unlikely the foam will get into all the cracks and crevices to form a tight air seal. Also, there is an increased risk of foam blockages that could cause bowing of the drywall.

Can I fill existing walls during cold weather?

Spray foam uses heat to cure, and should be sprayed to surfaces between 65 and 85 degrees Fahrenheit. But if it’s cold outside, don’t wait until Spring to do the project! Turn up the heat in the house or use a direct-heating source on the wall you are filling.

How do I calculate how much I need for my project?

First, measure the length and height of the vertical walls you’ll be filling. Multiply the length times the height of each wall and add those totals together. Then, multiply that new total by the number of inches deep your wall is. For example, if your wall is newer construction 2×4, multiply the total square footage times 3.5″. This will give you the total board feet of foam you will need for your project. It is a good idea, especially for this type of project, to multiply that total times 1.2 to add a 20% buffer to make sure you have enough. Divide that total by 600 (if the total number is more than 600) to find out how many kits you will need. Each Foam it 602 Slow Rise kit has enough chemical to produce 602 board feet of foam in free-rise.

Is this the product to use for filling pontoons?

Foam it Green Slow Rise is the right product to fill a pontoon for buoyancy. It is important to keep the foam out of direct contact with sunlight and water.

What do I need for doing a slow rise project?

For blind filling projects, don’t stick the nozzle directly into holes in the wall. It won’t fill the wall and will likely jam the gun. Purchase clear plastic hose that snuggly fits over the end of the black nozzle. What we’ve found works best is 5/16” inner dimension, 7/16” outer dimension size clear tubing. Foam flowing through this tube will appear green. If it is not, stop spraying. Cut tubing into 3-4 ft lengths. Drill holes every 3 to 4 ft up the wall. Use a new nozzle and length of clear plastic hose for each hole to avoid the curing foam in the line. Lower the line into the hole and pipe the foam into the hole. Slowly pull the hose back out so the foam is dispensed higher and higher. Let it cure and then proceed with the next hole up. Slow rise foam takes 2 minutes to rise. Allow each section cure for at least 20 minutes before adding more. You may purchase the correct extension hose with more nozzles as a package from us HERE.

Do I need to use the whole kit in the same day?

Foam it Green Slow Rise 602 kits are designed to be used within 30 days of being opened. If you do not complete your project the day you first use the kit, simply follow the shut down for reuse instruction on page 8 of the instruction manual. Failure to follow these instructions can stop your kit from operating correctly the next time you go to use it, which may lead to the purchase of replacement parts.

What color should the foam be?

Foam it Green Slow Rise has a dark yellow A component and a blue B component that when mixed, creates a light green color foam. When you are putting liquid foam into a wall, it is important to know it is mixing correctly, and Foam it Green’s green color will give you that confidence.
