Metal warping and clogged air lines

We are the company that people contact when they require additional muscle for cleaning jobs. Some stains are so tough that elbow grease alone won’t be enough. Things like old paint, soot, and even mortar need specialist attention if you hope to get rid of them. Our team can provide this to you. We’re the foremost establishment working in sand blasting North London has.

Our service is an efficient method of removing rust if done correctly. If you make the wrong moves however, you can harm the underlying metal. In addition it’s possible to cause a huge mess. With the right understanding, sand blasting isn’t a difficult technique to use. Read on to discover our top advice for this practice.


Metal can warp easily if you blast media at it for too long. The particles create friction when they encounter the surface. This in turn generates heat. The metal can expand as it heats up. Normally, this happens outwards.

While blasting, it’s nearly impossible to detect metal warping. This is unless the metal makes a loud “pop” noise. As a result you need to work carefully and shouldn’t blast the same area for too long. A couple of seconds is sufficient. Let that area cool before you blast it again.


It’s also possible for you to clog the air line. The process uses compressed air to propel media at extreme speeds. The issue is that there could be moisture in the air. If there is it can end up in the blaster’s tank. As a result it can affect the media. In the worst cases this can create clogs of media that cannot be fired out of the hose.

Luckily there is a way of preventing this completely. Simply clear the air line after every use of the blaster and keep an eye on the moisture.

Another thing to keep an eye on is the particle size of the media. You may need to use a larger hose for bigger materials, including glass beads or steel shot.
