Dustless Blasting
Wet abrasive blasting: the abrasive is mixed with water before it leaves the nozzle, which suppresses dust and reduces heat and sparks.

Surface Treatment & Coatings
Surface preparation with techniques that minimize environmental impact, and paints, protective linings and thermal linings applied by certified personnel.
- 3surface preparation technologies: Dustless Blasting, Gritblasting and Sponge Jet
- 2paint application methods: conventional and Airless
- POLYCORPresins, rubbers and protective polymers for linings
The service
We protect steel from the marine environment in two stages: first we prepare the surface, with techniques and equipment that minimize environmental impact, and then we apply the system that will protect it.
- Surface preparation with Dustless Blasting, Gritblasting and Sponge Jet
- Paint application by conventional and Airless methods, with certified personnel
- Linings with resins, rubbers and protective polymers from leading manufacturers such as POLYCORP
- Thermal linings for piping, equipment and tanks that handle high temperatures
Surface preparation
A coating lasts as long as the surface beneath it allows. We use state-of-the-art techniques and equipment for surface preparation, minimizing environmental impact.
Gritblasting
Dry blasting with angular abrasive (grit). It removes rust, mill scale and old coatings, and leaves the anchor profile that the new coating needs to adhere.
Sponge Jet
Abrasive embedded in sponge particles that flatten on impact and trap most of the dust and rebound. The media can be collected and reused several times.
Paints and coatings
We have certified personnel with experience in applying paint by conventional and Airless methods.
Conventional spray
Compressed air atomizes the paint. It gives fine control of the finish and suits smaller areas and detail work.
Airless spray
A pump forces the paint at high pressure through a small tip, without atomizing air. It allows thick films and high output on large surfaces such as hulls, decks and tanks.
Protective linings
We apply linings with resins, rubbers and protective polymers from leading manufacturers such as POLYCORP, guaranteeing durability and resistance.
Thermal linings
With more than 40 years of experience, we have taken an active part in engineering projects and in the application of thermal linings for piping, equipment and tanks that handle high temperatures.
Environmental care
We choose surface preparation techniques and equipment that minimize environmental impact. Tanzaca's certifications include RACDA, Venezuela's registry of activities capable of degrading the environment.
