Masonry & Mortar Cements

Quality masonry and mortar cements, from brands you trust.

Our masonry product line offers quality, flexibility and most of all, choices.

First, we offer the basics: masonry and mortar cements, available in ASTM C91 Types M, S and N, suitable for all masonry construction. Then we kick it up a notch with a pigmented masonry – Rainbow Mortamix Custom Color Masonry Cement – that is available in 70 standard colors, and can be mixed and customized to meet any design needs.

Materials That Perform: Rainbow Mortar Scale

Masonry Cement​ is specially-formulated to ensure a uniform product and color. It’s a quality masonry mortar for use in almost any brick, block, and stone masonry construction.  

Masonry cements are composed of Portland cement, plasticizers, and air entraining additives, which we proportion at the cement plant under controlled conditions in a single blending operation. The result is an easier process — no need to field-proportion cement and lime — and a better outcome — a more uniform mortar.

Mortar Cement​ offers superior performance: durability, weather resistance and aesthetics. It is suitable for all masonry construction, especially projects that require higher flexural bond and compressive strengths.

In independent testing, mortars made with our Mortar Cement exceeded the flexural bond strengths required in:

  • ASTM C 1329 Standard Specification for Mortar Cement
  • International Building Code Standard 2103.7 Mortar
  • CSA-A3002 Masonry and Mortar Cement.

They also achieved flexural bond and compressive strengths that meet all seismic zone requirements — enhancing structural stability and maintaining the margin of safety.
