Vendor Part # 181178

Sika Diamag 7 is an economical, mineral shake-applied surface hardener. It contains carefully graded, hard wearing particles, which provide an exceptionally durable surface. Special dispersing and plasticizing agents promote ease of incorporation into the concrete surface. Sika Diamag 7 is premixed and ready-to-use

What is a Surface Hardener?

Plain concrete floors do not offer the type of abrasion and impact resistance required in modern manufacturing environments. They can be a source of dust, premature wear and are relatively porous allowing penetrations by chemicals and pollutants of all sorts. Sika Canada Inc. has developed an extensive line of floor hardener and ancillary products that improve the performance of plain concrete floors. Sika floor hardeners increase concrete density as well as abrasion and impact resistance on the wearing surface. This results in a measurable upgrade in durability of three to eight times over plain concrete. Ultimately, this means your floor will have a longer life cycle, free of costly repairs and inconvenient shutdowns.

How it works

Sika combines carefully selected aggregates, Portland cement and wetting agents into a dry powder blend. During the concrete finishing process this powder is broadcast onto the concrete surface and “floated” in, creating a new fully bonded layer. This layer has a lower water/cement ratio and coats the face of the floor with durable aggregates, creating a superior wear resistant surface.

Factors to consider

There are three key variables to consider when selecting a floor hardener. Aggregate type, interlocked gradation and application rate, work together to produce a range of floor hardener applications. Sika floor hardeners combine these factors to produce wearing surfaces for industrial, commercial and institutional floors, whether light, medium or heavy-duty in-service conditions exist.



Contains cement and silica sand which may, in certain cases, cause skin irritation. Avoid breathing dust. Use only with adequate ventilation. In confined areas, use of a NIOSH/MSHA approved respirator is recommended. Consult product label for additional information.
