Description
Overview:
The Errut Floor Grinding Stone is a medium 36 grit bonded abrasive block for preparing and smoothing concrete floors. Made by Altrad/Belle, it is designed for use on floor grinding and polishing machines that accept stone blocks sized 4" x 2" x 2" (approximately 102 mm x 51 mm x 51 mm). The medium grade offers a balanced cut that removes high spots and laitance while leaving a consistent surface ready for finer finishing or coatings. Each stone is sold individually, so you can replace single blocks as they wear; most machines typically use six stones at a time for even performance. Built for reliability and long service life, this stone helps tradespeople and DIY users achieve a neat, uniform floor surface on concrete substrates.
Key Features:
- Medium 36 grit for a balanced blend of stock removal and surface smoothness
- Size 4" x 2" x 2" (approx. 102 mm x 51 mm x 51 mm) to suit common floor grinding carriers
- Durable bonded abrasive construction for consistent wear and predictable results
- Sold individually, allowing cost-effective replacement of single worn stones
- Typically six stones required per machine for optimal balance and coverage
- Suitable for many Altrad/Belle and similar floor grinding machines that take this block size
- Straightforward to fit and replace in the machine's stone holder or plate
- Helps flatten ridges, remove surface laitance, and key concrete ahead of coatings
- Provides an even finish ready for progression to finer grits if required
- Reliable performance for site work, refurbishment, and routine floor maintenance
Typical Applications:
Used for concrete floor preparation on building sites, workshops, garages, and industrial units. Ideal for removing high spots and trowel marks, blending patch repairs, and creating a keyed surface for screeds, levelling compounds, paints, or sealers. Suitable for initial passes before moving to finer grades for final finishing.
