Sikafloor 1 Metal Top | MCT CHEMICALS | SIKA PAKISTAN

Uses
Sikafloor®-1 MetalTop should only be applied by experienced professionals. It creates a non-staining, extremely hard-wearing metallic dry shake topping for monolithic concrete floors. When applied to fresh, wet concrete and troweled in, it forms a coloured, highly abrasion-resistant, smooth, and dense surface.
Typical applications include:

• Warehouses
• Heavy-duty distribution centers
• Factories and manufacturing facilities
• Transport terminals
• Power stations

Characteristics / Advantages
