For Thorough Surface Preparation
Concrete is a durable and versatile building material. Over time, however, it is heavily stressed by weathering, mechanical loads, chemicals, or abrasion. Cracks, efflorescence, dirt, algae growth, or old coatings can impair the stability and appearance of structures.
For successful concrete renovation, thorough surface preparation is crucial. Blasting agents remove damaged layers, deposits, or loose particles. This creates a structured, clean surface that optimizes the adhesion of renovation plasters, coatings, or protective systems.
Why Blasting Agents are Important in Concrete Renovation
The demands on concrete surfaces in the renovation sector are high: the surfaces must be load-bearing, clean, and roughened to securely receive new layers. Blasting agents ensure that:
- loose particles, old coatings, and deposits are removed,
- the surface roughness required for the adhesion of renovation plaster, epoxy resin, or coatings is created.
- the adhesion and longevity of the renovation are increased.
- In addition, standards such as DIN EN 1504 for concrete repair are complied with.
By correctly choosing the blasting agent type, grit size, and blasting pressure, efficient cleaning, material preservation, and maximum adhesion can be combined.

Advantages of Using Blasting Agents in Concrete Renovation
- Effective removal of old coatings, deposits, and loose material
- Standard-compliant surface preparation for renovation plasters and protective systems.
- Material-friendly cleaning of sensitive concrete surfaces
- Optimal adhesion for new coatings or repair materials.
- Longer lifespan and stability of the renovated components.
Tips for Using Blasting Agents in Concrete Renovation
Treat soft, delicate surfaces only with gentle blasting agents. Heavily damaged or soiled concrete surfaces require blasting agents with high material removal rates.
For renovation plasters or coatings, a certain roughness is usually recommended depending on the material and coating system.
Too high a pressure can damage the concrete; too low a pressure will not sufficiently remove deposits.
With fresh concrete or damp surfaces, blasting can lead to pore damage. Dry material ensures better results.
Blasting work generates dust, abrasion, and splashes. Respiratory protection, safety glasses, gloves, and protective suits are mandatory. An extraction system or dust filter increases safety.
After blasting, surfaces should be treated promptly with renovation plaster, coating, or corrosion protection to ensure optimal adhesion.
