Guard Hardener WO– Strengthen and Protect Concrete, Stone and Brick from Stains, Oil and Water

Deep-strengthens weak concrete, stone and brick while protecting against oil, grease, stains and water. Ideal for garages, terraces and exposed areas.

Guard Hardener® WO strengthens weak, porous concrete, stone and brick while providing advanced protection against stains, oil and water.

It penetrates deep into damaged or ageing areas to restore strength and make them solid again. Long lasting: At the same time, it protects against common staining substances such as oil, grease and everyday dirt, preventing them from soaking in and leaving marks.

This makes it especially suitable for areas exposed to vehicles, food, or frequent use, where both durability and cleanliness are essential.

It also limits water penetration, helping reduce damage caused by moisture, rain and repeated wetting and drying cycles.

After application, treated areas become stronger, cleaner and easier to maintain, while keeping their original appearance.

Guard Hardener WO is ideal for garage floors, terraces, outdoor areas, workshops and any place exposed to stains or heavy use.

It can be applied on dry or slightly damp areas, making it practical for renovation projects.

Easy to apply, it is sprayed or rolled until saturation. Once dry, the treated area is more resistant, better protected and easier to clean.
