Professional Blast Cleaning Services

At GT Problast Ltd we carry out private, commercial and industrial blast cleaning services and are capable of blasting anything from car parts and gates to bridges and power stations!

We use a variety of different blast media depending on the job, which include:

  • Crushed Glass – Manufactured from recycled glass bottles. It is silica, toxic free and inert. It produces a much lighter and finish in comparison to other slag blast media. It is ideal for removing of coatings and lighter surface rust. Crushed glass is available in many grades and can be generally used on most blast cleaning jobs.
  • J Blast – Commonly known as copper slag, J blast has been used in the industry for many years. It is much harder and denser than crushes glass and can be used to remove heavy rust from corroded steel and thick coatings. It has a much faster cleaning rate than glass and is available in many different grades.
  • Glass Bead – Mainly used for cabinet work, Glass bead is spherical in shape and is inert. IT is generally used for removing light burring, polishing or peening the surface. Due to its shape and not being as hard as some other blast media, it does not leave much of/if any profile on the material being blast cleaned. This makes it a perfect product for cabinet work on alloy prior to being polished.
  • Soda – Soda is a soluble product and is environmentally friendly. As it is non-abrasive and non-destructive, it leaves no/very little profiling to the material being cleaned. It is a gentle process which can be used to neutralise rust, water damage and fire damage; removing toxins, odours and bacteria.
  • Garnet – The vast majority of the Garnet we use is mined from Australia. It is a very hard material which is used for its superior coating preparation and adhesion properties. As Garnet is a natural product and environmentally it is commonly used in protected areas such as national parks etc. if there is a risk of any media escaping into the atmosphere.
  • Additional blast media we use include steel shot, walnut shells, aluminium oxide and olivine etc.
