We’ve all heard about the ease and time-saving qualities of using fence post foam vs concrete with the construction of posts, but what about the longevity and durability of post foam? Will it last? Will it hold up? Well, the answer actually lies within a chemical reaction.

To understand the longevity and durability of foam post foam, we first need to understand what happens when you see that foam appear. Fast 2K is based on a reaction that creates a cross-linked polyurethane. Polyurethane is the type of polymer and cross-linked means that the polymer chains are connected together.

Polyurethane bonds are generally stable, but the subterranean environments that are created when installing fence posts provides a climate where polyurethane is even more stable. This is what results in the excellent durability of fence post foam.

So Fast 2K™ is durable, but will it actually last a long time? The question of longevity when it comes to foam post vs concrete is a topic that is often discussed because concrete has traditionally been the material that is the best for long-term performance and stability. That was before the invention of the fence post foam filler.

Fence posts last an average of 15 – 20 years. What typically happens is that fences start failing due to rot of the post at or below the ground line. The Fast 2K technology has been used in the field for more than 30 years, without degradation of the product or posts. Fast 2K becomes water-resistant after fully cured and can be applied in a way to reduce the moisture reaching the post and increase its lifespan and durability. The versatile formula prevents water from getting into the seams of each post, thereby decreasing expected rot, rust, deterioration, and other water-related damages increasing the longevity of your fence post – making Fast 2K the longest and most durable option for your next fence project.

There are chemical and practical qualities of post foam that can extend the longevity of your fence post not only keep up, but surpass the durability of concrete. Add these advantages to your list of reasons why to use Fast 2K™ instead of concrete. Find where to buy Fast 2K and get your project started today!
