It is used of remove mill scale, rust, old coatings and impurities from surfaces and to prepare the surfaces for any protective coatings if required. Effective and correct surface preparation is the key to successful corrosion protection. uNyazi specialise in the following surface preparation methods:

Conventional Grit Blasting
Hydro Blasting
Mechanical Cleaning


Ultra-High Pressure Blasting is the use of high pressure water jetting with or without the addition of other liquids or solid particles to remove unwanted matter from various surfaces.


Sponge-Jet’s unique technology allows uNyazi to change from costly outdated processes and improve coating performance. Achieve sustainable, safe, environmentally-responsible and superior surface preparation.
