This product has following uses;

•  Patching mortar for use on vertical and overhead concrete and masonry surfaces

•  Can be used as a bedding mortar joining vertical and horizontal precast members together
•  Restoration of architectural details, bridges, parking structures, tunnels, precast concrete products, retaining walls, balconies, etc

Ideal application conditions are when air, material and substrate temperature are between 40°F (4°C) and 80°F (27°C). For applications outside this range of temperatures, contact ProSpec® Technical Services.

• Hot weather and job conditions above 80°F (26°C) will reduce working time and accelerate set, while cold temperatures below 40°F (4°C) will have a retarding effect.

• When Dry Pack consistencies are required, immediately apply the fresh mortar into the entire surface, forcing Precast Mortar Grout firmly into the previously prepared area insuring full contact with all bonding surfaces.

• Slightly overfill the area and after initial set, using a steel trowel, shave Precast Mortar Grout to the desired final profile, shaving the patch from the center towards the bond edge at the existing surfaces, before the patch hardens insuring that nothing extends over the repair edges. A wet spray may be used for final shaping.

• In deeper areas additional lifts can be made after the original patch has reached initial set. Score and roughen the original lift layer to improve bond between applications.

• Precast Mortar Grout can be placed in lifts up to 5” (127 mm) on vertical and overhead applications by compacting the mortar in place until initial set takes place. In applications where the thickness is greater than 3” (76 mm) up to 33% clean, washed and dried 3/8” (10 mm) pea gravel, based on the weight of the grout may be added. (15 lb (6.8 kg)) pea gravel to 50 lb (22.7 kg) Precast Mortar Grout)).

• When placing adjoining precast members use the mortar consistency water level 4.5 qt (4.3 L) to 50 lb (22.7 kg) bag. Place the mortar on the horizontal member and then place the vertical element. Let the mortar reach a shavable consistency and shape as outlined above. A joint striking tool will be helpful to insure a clean seam.

Test results obtained under controlled laboratory conditions at 73°F (22.7°C) and 50% relative humidity unless otherwise specified. Reasonable variations can be expected due to atmospheric and job site conditions.
