RUBI Polishing Block Grit 120 – Silicon Carbide Hand Sanding Block for Tile, Stone & Glass Edge Finishing

Unlike ordinary sanding sponges that wear out quickly or leave inconsistent scratches, the RUBI Polishing Block Grit 120 uses a dense silicon carbide abrasive bonded to a rigid foam core. This combination delivers controlled material removal on hard surfaces while the block shape keeps edges flat and corners crisp. It is the same block used by professional tilers to refine cut edges before grouting, and it works equally well for restoring dull stone or removing micro-chips from glass.

Highlights

• 120 grit silicon carbide abrasive for medium smoothing and deburring
• High-density foam/rubber body resists deformation during heavy hand pressure
• Rectangular profile reaches into corners and along straight edges
• Wet or dry use – wet sanding reduces dust and extends abrasive life
• Suitable for ceramic, porcelain, natural stone, marble, granite and glass
• Ergonomic grip reduces hand fatigue during repetitive edge work

In daily use

After cutting a porcelain tile, the exposed edge often has tiny chips and a sharp burr. Running the RUBI block along that edge with light, even strokes removes the burr and softens the profile without rounding it excessively. For glass or polished stone, use the block wet to achieve a fine satin finish that blends with the surrounding surface. The block can also be used to clean grout haze from textured tiles or to refresh the surface of honed marble before sealing.

Final note

For professionals who finish tile edges by hand, the RUBI Polishing Block Grit 120 is a dependable daily tool. Its silicon carbide abrasive cuts faster than aluminium oxide on hard materials, and the block format gives you more control than a loose sheet. Keep one in your tool bucket for on-site touch-ups and one in the workshop for final preparation before installation.
