Reconstec 350 (Limestone)
Reconstec 350 (Limestone) is a mortar specially designed for the restoration of limestone. This product has non-shrink properties and provides a very good bond to stone. Reconstec 350 (Limestone) is easily applied to clean, sound substrates, and does not contain synthetic polymers.
• The same coefficient of thermal expansion as limestone
• Very good adhesion to substrates
• Not a vapour barrier; completely breathable
• Good freeze-thaw resistance
• Easy-to-use
• Pigmented versions available

2. USES
Please refer to Features & Benefits section.
3. PROCEDURES
Surface Preparation: Remove all impurities, dirt, grease, other bond inhibiting materials from surface. Preparation work should be done using manual or pneumatic cutting techniques. Be sure patch area is not less than 10 mm (½”) deep. Dampen surface to be repaired with clean water.
Mixing: The mixing ratio is approximately 5 parts powder to 1 part water. Use clean container. Pour water into mixing container. The mixing may be done by hand or using a slow speed drill (300 rpm-450 rpm) with a mixing paddle. The mortar should be the consistency of damp sand. Do not over water. Do not over-mix. Working time is approximately 1 hour.
Application & Finishing: Mortar must be scrubbed into substrate, filling all pores and voids. Use a steel trowel. Force material against edge of repair, working toward center. When the mortar is the consistency of dry sand screed to desired finish.
4. CURING
Use mist spray of clean water for at least 3 days after installation, several times a day.
5. TECHNICAL DATA
Application Time: Approximately 15 minutes after mixing. Application time is dependent on temperature-it is faster in heat, slower in cool.
