Tercoo Rotating Blasters

Tercoo Perago discs are powerful rotating cleaning discs designed for the fast and controlled removal of various layers and contaminants. They effortlessly remove tar, paint, rust, bitumen, and antifouling from steel and cast iron, and are also suitable for scraping plaster, textured coatings, and similar materials from stone surfaces. In addition, Perago discs are widely used for removing gelcoat from boat hulls. The result is a surface with the correct roughness and cleanliness for optimal adhesion of paint or coatings.

Benefits of rotating blasters

Using a rotating blaster offers several benefits: it provides a fast and efficient workflow, saves considerable labour time, and can be easily mounted on a polisher or drill. This makes the Tercoo Perago disc accessible to both professionals and DIY enthusiasts. The result is a surface with the correct roughness and cleanliness for optimal adhesion of paint or coatings. This not only improves the quality of the finish, but also enhances the durability and lifespan of the new coating system.

The operating principle of Tercoo Perago discs

The Tercoo Perago disc removes coatings and deposits in an efficient and controlled manner using hardened steel pins mounted on the disc. During rotation, these pins chip away the existing layers of paint, coatings, or tar without damaging the underlying material. A major advantage is that the treated surface is immediately ready for a new primer, allowing the full coating system to be rebuilt. Because the Tercoo Perago disc does not generate heat, it is also highly suitable for removing soft coatings, such as tar products and bitumen. This makes the system ideal for stripping steel boats, as well as other steel structures. The specially designed carbide tips make only light contact with the surface, effectively scraping away deposits and leaving a clean, even finish.

Which Tercoo rotating blaster do I need?

The Tercoo rotating blasters that can be mounted on a drill are available in three versions:

Tercoo Single
A rotating cleaner for small jobs, hard-to-reach corners, spot repairs, and small surfaces, such as blistering under paint, rust spots, or weld seams.

Tercoo Double
A rotating cleaner for surfaces up to 10 m². This version is ideal for stripping a cast-iron keel, parts of a boat deck, or large rust patches.

Tercoo Triple
A rotating cleaner for large surfaces up to 30 m². With the Tercoo Triple, you can easily strip an entire deck or the full underwater hull.

For even larger surfaces, a professional machine with 8 discs is also available.

For surfaces larger than 30 m², we recommend the Tercoo Multi (8 discs), a professional machine designed for larger surfaces.

The use of Tercoo Perago discs

Tercoo Perago discs are mounted in a power drill and used at speeds of up to 4000 rpm. Start the drill and allow it to reach operating speed, then press the disc against the surface with light pressure. The hard steel pins will then effectively remove the paint, revealing a clean surface.

Tercoo Tools

To make the Tercoo rotating disc easier to use, you can equip the discs with an adjustable guide and dust cover, which are also available in combination:

• Dust cover: to reduce dust and simplify cleaning, you can use a dust cover mounted on the disc.
• Adjustable spacer: the adjustable spacer ensures that only the defined layer thickness can be removed.
