Pour Foam Instructions - Mixing and Pouring


Our Pour Foam systems are closed cell rigid polyurethane foams designed for molding, void filling, and insulation applications. Available in 2lb. Or 4lb. Per cubic foot densities.

The unique handling characteristics of the series systems provide ease of mixing by hand and produces a uniform product with excellent cell structure.

Product temperature must be stabilized at room temperature @ 72°F to 82°F before use to get the best results. If the foam is not maintained between these temperatures, the foam will become too light or too dense.

Tip: A few days before use, we recommend storing the product at room temperature to let it stabilize. Product may be stored between 65°F to 85°F.


Mixing tools and containers should be perfectly clean and made of metal, glass, or plastic.
Before mixing, know you are using a mix ratio of 1:1 plus. After dispensing the correct amounts of Parts A and B into mixing container, mix thoroughly for 45 seconds. The color of the foam will change to a light cream color and should be blended evenly before pouring.

Stir quickly but do not induce air pockets. Make sure that you scrape the sides and bottom of the mixing container several times.
Remember, foams cure quickly. Do not delay between mixing and pouring.


Pour your mixture in one area at a time at the lowest point of the fill area and let the mixture find its level. Leave enough room for the foam to grow in the containment area. Let the foam cure for at least 20 minutes before handling.

Once the foam is fully cured, it can be sanded, drilled, or machined to fit any application. This foam can also be primed and painted for finishing applications.


  • Wear safety equipment at all times when using the product.
  • Calculate the waste when ordering for a project.
  • Calculate foam needed before mixing 
  • For larger amounts mixed - Use an electric drill or jiffy mixer.

Storage: Both components must be stored in tightly sealed containers and protected from moisture, at temperatures above 65°F.
