Type N – PRO MASONRY
ProMasonry Type N Mortar Mix exceeds the requirements of ASTM C387 and ASTM C270 for compressive strengths when used as directed.
For laying brick, block and stone, or pointing, plastering and stuccoing.
Remove all loose and/or deteriorated material as well as any surface contaminants such as oil, paint, grease, etc.
Empty the contents of the bag into a clean wheelbarrow, mortar box, mechanical mixer or other mixing vessel. Form a crater with a shovel or hoe in the center of the dry mix. Mix sufficient water to achieve desired workability.
For hand mixing
Blend dry mix with a shovel or hoe from the outer edges working the material towards the center. Continue mixing until all free water is used and all the aggregate is uniformly coated with cement
For mechanical mixing
Mix the material for three minutes.
Joints can be finished when material has begun to set and the surface has a thumbprint hard consistency. Mortar joints can be finished with a jointing tool.
Protect from direct sunlight, wind, rain and frost during the curing period.
Clean tools and equipment with water immediately after use. Cured material will need to be mechanically removed.
