Abrasive blasting & sandblasting

Three stripping levels, one single company. We choose the method suited to your surface, or combine them for maximum efficiency: from delicate facades to heavily corroded metal.

Our techniques

Three stripping levels

01

Abrasive blasting

Fine natural abrasive at low pressure. Preserves sensitive surfaces: wood, stone, brick, facades. No water or chemicals.

02

Sandblasting

Coarse abrasive at high pressure. Bare metal exposure, removal of deep rust and industrial coatings.

03

Combined COB71R

Abrasive and dry ice in the same flow. Thermal shock plus mechanical action for extreme contamination and post-fire situations.

Applications

Sectors we work with

Heritage & monuments

Stone facades, sculptures, listed buildings, non-abrasive cleaning that preserves the original material.

Industry & structural steel

Rust removal, paint stripping before recoating, structural steel preparation.

Building & facades

Renovation, facade cleaning, moss and biofilm removal without water infiltration.

Post-fire

Soot and corrosive residue removal on structures and equipment after fire damage.

Graffiti removal

Tag and graffiti removal on stone, brick, metal and wood without damaging the substrate.

Wood & timber frames

Beam and timber frame cleaning, moss and mould removal without adding moisture.

Frequently asked questions

Abrasive blasting & sandblasting

The choice depends on your surface, the type of contamination and your constraints. Icetec assesses this during a free site visit and recommends the most suitable technique, sometimes combining several methods on the same job.
No if the pressure is correctly adjusted. A test is always performed on a discreet area beforehand. Abrasive blasting is specifically chosen for its gentleness on sensitive materials such as natural stone.
Yes, sandblasting is our preferred method for exposing bare metal and removing deep, adherent rust before repainting or recoating structural steel.
It combines abrasive and dry ice in a single flow, adding thermal shock to the mechanical action. It is reserved for the most extreme contamination, such as post-fire soot on complex structures.
Yes, for most jobs a free site visit lets us assess the surface, contamination level and access constraints before recommending the right technique and providing an accurate quote.
