SURFACE PREPARATION

Steel Shot/Grit Blasting

Steel Shot and Grit blasting primarily used for preparing steel for the application of protective coatings. 

Garnet Blasting (also known as Sand Blasting)

Commonly known as Sandblasting, Garnet is now used in place of Silica, due to health and safety risks associated with Silica. Garnet Blasting is primarily used for preparing steel for the application of protective coatings but is also used when non-metallic media is required, for example, aluminium blasting. 

Glass Bead Blasting
Glass Bead Blasting is a specialised media used for blasting aluminium and stainless steel, depending on the application required.

Soda Blasting

Soda Blasting is used when a surface needs to be cleaned without creating a profile or a minimal profile is required. Essentially, it is used as a cleaner.

Ultra-High Pressure Water Blasting

Ultra-High Pressure Water Blasting provides a powerful, fast and economical solution for your blasting projects. With pressures from 20,000 to 40,00 (PSI), Ultra High-Pressure Water Blasting quickly erode any type of tough surface build-up using only water, with no abrasives, chemicals, solvents or caustics - so, it’s safe for the environment.

OFF-SITE INTUMESCENT PAINTING

 

Utilising our Comblast teams, we can undertake off-site intumescent applications providing you with steelwork ready to be erected with Intumescent and topcoats already applied if required. This saves you programme time, H&S and access costs. We also have a mobile team that follows the installation of the steel to undertake touch-ups and welding remedial work.

 

We have a range of intumescent products available that provide greater durability than the standard thin-film sprays, minimising the chance of transport and installation damage.

SPECIALIST COATINGS

 

Metal Arc Spray

Two metal wires are fed into a thermal arc to liquefy the metal and then delivered to the steel in a stream of air. This is commonly used for applying liquid metal coatings to steel. Metal Arc Spray is an alternative to Hot Dip Galvanising.

PROTECTIVE COATINGS

Epoxy Coatings

Epoxy coatings are used as a protective coating for steel and concrete. Epoxy coatings can be applied by our teams on-site, and offsite.

 

Polyurethane Coatings

High performance aesthetically pleasing topcoats.

 

Intumescent Coatings

Off-site application by ComBlast Mobile

Structural protection for steel, in the event of a fire (fire protection)

Tank Linings
