Three Different Types of SPF Blasting

Spray polyurethane foam is an excellent material when it comes to interior and exterior property insulation, protection, and future-proofing your aging roof. Unfortunately, even with the finest open or closed-cell SPF available in the market, it can get old and become more of a liability than an asset. When this happens, the durability and capability of SPF becomes a disadvantage — it can be very difficult and extremely dangerous to remove them on your own.

We at Ener Spray have used many of the usual strategies in removing unwanted and aged SPF and improved it by a mile with our special capabilities. We perform the following and take it to the next level with specialised adaptive methodologies:


Combining sand with high-pressure air creates surface abrasions on cured SPF. In doing so, it will dislodge the unwanted SPF without any incident in the shortest amount of time possible. However, only well-trained specialists can achieve exceptional sandblasting results safely provided high-impact sand is dangerous to the body. 

The high impact of sand and micro-fragments allows property owners to enjoy SPF-free surfaces without the possible risk of material damage thanks to the consistent spray of sand that glass manufacturers use for making mirrors and glass smooth and consistent.

Shot Blasting

This method is useful for panel surface SPF removal. Similar to sandblasting, shot blasting uses fragments to remove unwanted SPF from the panel. Even if it has cured or is old, the dried SPF will crumble. The machine can then restore the panel’s early aesthetic through 1-2 shot blasting cycles.

Unlike sandblasting, shot blasting is a stationary tool that’s perfect for removing SPF only on removable metal or concrete surfaces that unwanted SPF has contaminated. On the other hand, it provides a better finish than sandblasting because of the smooth, consistent surface of the shots inside the machine.

High-Pressure Water

A tried-and-proven way to remove the most stubborn matter and other materials inside machines, high-pressure water is definitely the most basic yet efficient way to soften up SPF that have only begun to cure in the last few hours. In fact, it can quickly remove soon-to-dry SPF without any consequences.

High-pressure water is the safest among the three methods of removing SPF from surfaces. However, it does not leave any clean finishes that sand and shot blasting can do. Additionally, contractors can conveniently use local water sources to begin SPF cleanups, which make this procedure greatly accessible and efficient.

Why is SPF Blasting Important For Property Owners?

In some cases, faulty SPF applications happen. Even our professional team at Ener Spray admits that some off-chances leave surfaces with uneven SPF that had begun to cure over a few hours. With effective blasting methods to remove SPF, you won’t have to worry about uneven surfaces and excessive SPF use. We can re-apply removed SPF and make sure your property gets the best interior and exterior SPF application result possible without any hassles to you.
