Masonry Mortars & Repointing Products

SPEC-JOINT 46 is a series of pre-colored, prepackaged, lime and cement-lime mortars for use in new construction and restoration. Lime mortar is formulated to match traditional historic mortars, and cement-lime mortars are formulated in accordance with ASTM C-270 specifications to provide consistent, reliable results in both performance and appearance. SPEC-JOINT 46 is simply mixed with water prior to use, and is applied in accordance with Standard Procedures for use of masonry mortar.

Ice -9 (RL-9) is an additive for mortars, stuccos and concrete that improves freeze-thaw resistance even in the presence of ponded deicing salts. It also improves bond strength and reduces shrinkage.

ROSENDALE 10C are natural cements for use in restoration of historic concrete and masonry and in green building. The cements are prepared in conformance with traditional specifications, faithfully reproducing the natural hydraulic cements used in the 19th and early 20th Centuries. Mortars, stuccos and concretes based on natural cement have endured for more than 200 years, even under severe coastal and seawater immersion service exposures, and feature high vapor permeability, tenacious adhesion and low modulus of elasticity.

ROSENDALE 11G are pre-packaged natural cement-based grouts for filling of voids in historic concrete and masonry. Grouts based on natural cement have endured for more than 135 years, even under severe coastal and seawater immersion service exposures, and feature high vapor permeability, tenacious adhesion and low modulus of elasticity.

ROSENDALE 11Gi is a pre-packaged natural cement-based injection grout and adhesive. Grouts based on natural cement have endured for more than 135 years, even under severe coastal and seawater immersion service exposures, and feature high vapor permeability, tenacious adhesion and low modulus of elasticity. Their primary use is for filling cracks and voids in masonry. Rosendale 11Gi’s fineness, tenacity and flow characteristics also make them excellent general-purpose masonry adhesives.

ROSENDALE 12M mortars are custom-matched, pre-packaged natural cement-based masonry mortars for repointing or rebuilding of historic masonry. The mortars are prepared on a project-by-project basis in conformance with specified mixes and/or traditional recipes for natural cement mortars, the most widely used hydraulic mortars in 19th century North America. Mortars based on natural cement have endured for more than 150 years, even under severe coastal and seawater immersion service exposures, and feature high vapor permeability, tenacious adhesion and low modulus of elasticity

ROSENDALE 13P is a series of custom-matched, pre-packaged natural cement-based mixtures for repair of stone, masonry, and historic concretes. They are prepared using a blend of natural cement and other mineral binders, and custom aggregates matching the composition and color of the original materials for maximum aesthetic, mechanical and thermal compatibility. ROSENDALE 13P is non-polymer modified.

ROSENDALE 14S are custom-matched, pre-packaged natural cement-based plasters for repair or replacement of historic renders and stuccos. It is prepared in conformance with traditional recipes for natural cement renders, which were widely used in the 19th and early 20th Centuries in North America. Stuccos based on natural cement have endured for more than 150 years, even under severe coastal service exposures, and feature high vapor permeability and low modulus of elasticity.

Rosendale Whitewash 15W is a series of custom-matched, pre-packaged coatings based on natural cement or natural cement-gauged lime. The coatings formulations incorporate traditional paint and whitewash recipes specified in 19th and early 20th Century U. S. Government specifications for durable whitewash. They are prepared as fully formulated, ready-to-use coatings for historic masonry substrates such as brick, stucco, stone and natural cement concrete. Rosendale Whitewash 15W features high vapor permeability, tenacious adhesion and low modulus of elasticity.

ROSENDALE 16 B Beton is a series of custom-matched, pre-packaged natural cement-based mixtures for repair or replacement of historic concretes. It is prepared in conformance with traditional recipes for natural cement concretes, which were widely used in the 19th and 20th centuries in North America. Concretes based on natural cement have endured for more than 150 years, even under severe coastal service exposures, and feature high vapor permeability and low modulus of elasticity.
