Black Lime Putty Mortar

Black Lime Putty Mortar is a carbonating, non-hydraulic mortar for bedding and re-pointing. It is premixed with sand and pigment and is ready to use.  It absorbs carbon dioxide in order for it to set.  Stand-alone sand binder strong enough for weight-bearing masonry structure The sand is a perfect blend of carefully graded, interlocking, sharp silica sand Easy work-ability with high plasticity (sticky). Up to 1 1/2″ of mortar will adhere to your slicker. Just the right amount of our lime putty to fill the void space in the sand. The lime binder is 98% calcium Cures/carbonates quickly and thoroughly with low shrinkage Water shedding with the correct joint finish Water releasing Highly permeable Self-repairing Cushions and flexes with normal building movements Tint-able for durable color matching Lasts in the bucket indefinitely. The mortar is freeze/thaw stable, however if the bucket of lime mortar freezes, the bucket could crack Our Black Lime Putty Mortar comes in a 5 gallon bucket and weighs approximately 85 pounds. Each bucket will re-point approximately 65 square feet for a 3/8″ wide mortar joint at 3/4″ deep. We recommend using our beater attachment to “knock up” (mix rigorously for 5 minutes) before using. This energizes the calcium in the mortar.  Remove the water on the top and save that water to put back on the top if the mortar is not all used at that time.  To avoid failure, do not re-point in temperatures below 40°F. For areas of high exposure such as chimneys and foundations: Adding pozzolan can be recommended. Pozzolan is a type of clay that makes Lime Putty Mortars more durable and robust in extreme environments. Click here to read more about Pozzolan. A note about color:  A slicked joint verses a weathered joint may appear to be two different colors even though they are the same color. Shadowing, joint recession, finishing techniques etc. will affect color perception. All ingredients sourced and made in the USA! Please follow all safety warnings and installation instructions! Pallets are available. A full pallet consists of 24 buckets and weighs 2,200 pounds.  Installation Guide Safety Data Sheet For Specifiers (manufacturer’s specs) Mortar Tech Sheet
