Grinding, shot-blasting and polishing of concrete and floor slabs

Grinding, shot-blasting and polishing of concrete and floor slabs

Professional grinding, shot-blasting and polishing of concrete and floor slabs are key steps to achieving a level, safe and aesthetically refined surface. At Calor d.o.o. we use specialized machines and abrasives to remove unevenness, open the concrete structure and prepare the substrate for further layers or a final finish.

Depending on project requirements, we can achieve a matte, semi-matte or high-gloss finish, as well as ideal preparation for epoxy, polyurethane and other industrial systems. Our goal is a lasting solution that combines functionality, durability and a modern look.

Service overview and challenges

Every floor has its history — from mechanical damage, spilled liquids and chemicals, to poorly executed finishes. The challenge is to remove existing damage and layers while preserving the necessary concrete strength and preparing the substrate for new loads.

By combining grinding with various grits, shot-blasting where additional roughness is needed, and a final polish or impregnation, we deliver surfaces that are easy to maintain, less dusty and more abrasion resistant. We pay special attention to working in active facilities to minimize disruption to your production.

Execution phases
  • Floor condition assessment:We inspect the existing concrete, identify coatings, cracks and unevenness, and define the required level of grinding, shot-blasting or polishing.
  • Surface grinding and shot-blasting:We use machines with diamond tools and shot-blasting heads to remove old layers, open the concrete structure and achieve the desired roughness or flatness.
  • Polishing and final protection:Depending on requirements, we perform multi-step polishing to the desired gloss and apply impregnations, hardeners or protective coatings that extend service life and simplify maintenance.
Frequently asked questions
When is grinding and polishing of concrete floors necessary?

Grinding and polishing are recommended for worn, uneven or stained concrete floors and as preparation for new coatings such as epoxy or polyurethane systems. It is also an ideal solution for spaces seeking an attractive yet durable concrete floor.
