Miraharden Plus is a lithium silicate treatment which penetrates deeply and reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores. This makes the surfaces tougher, easier to clean, and even water-damage resistant.

The product is typically used on new slabs either at the time of placement, or 28 days after curing or construction. It can also be used on a previously densified floor where sodium or potassium silicates were used, if the surface is starting to dust or deteriorate.
