Danish Concrete Hardener's concrete hardener is a non-toxic, concrete impregnation liquid for effective treating of concrete. It is water-based, colourless and is available in three different types – Floor, wall and block hardeners.
This hardener penetrates floors by 1-3 cm deep, and 10-15 mm for walls and blocks. It prevents water penetration and rapid drying of poured concrete and prevents cracks during hydration reaction. Your floors and walls will also become water repellent, oil stain repellent as well as slip, acid, chemical, fire and abrasion resistant.
