METHOD TO USE
Surface preparation
Proper repairs depend upon a solid bond between mortar and base surface. Thoroughly clean and roughen subject area. Remove any curing compound, grease, oil, loose carbonated concrete, dirt, dust, rust, etc... from exposed slab. Surface must be mechanically prepared to obtain sound concrete. The concrete surface that will receive the product must be sufficiently saturated with water during 12 hours before the application can begin. Do not apply on a surface where ponding water is present. 

Mixing 
Place mixing equipments close to repair area. Always mix by adding the dry product to the part B. Use a mortar mixer or 1/2" drill with mixing paddles. Place 5kg of liquid polymer in a clean mixing container. Measure water with reliable volume measure. Slowly add the powder while mixing until uniform. If the mixing should be performed manually, it must be done vigorously. Add the remainder of the liquid polymer . Repair mortar 219 should be mixed to the proper consistency depending upon project requirements. Mix until a smooth uniform consistency is obtained. 

Application method
Vertical surfaces
Apply a tight coat of Repair mortar 219 to surface using trowel, rubber float trowel or gloved hands to to force material into all crevices, cracks and edges to eliminate all air pockets and ensuring complete contact for a good bond. Apply material from same batch to build to desired thickness. Minimum thickness is 5 mm . Two layers of Repair mortar 219 may be applied in as little as 30 minutes after set time.

Applications greater than 50 mm thickness
Place one or two layers totalling not more than 50 mm thickness, leave surface rough, then damp cure. After 6 hours, apply an additional 1 or 2 layers totalling not more than 50 mm each. Finish final layer with steel trowel or sponge float. If material has begun to set prior to placing, discard it. 

Curing 
The curing must begin as soon as the final set is attained. The final set will vary depending on site conditions. Immediately after application the surface with clean potable water being careful not to erode the surface with water pressure. Continue this curing for at least 4 to 6 hours or tack rags over patch and keep wet for first 2 hours and leave rags for 4 more hours. 
.
HANDLING 
Repair mortar 219 should be stored in a dry place under shade, free from moisture contact. Remove splashes from skin with water. In case of eye contact, wash with plenty of water. If irritation persists, seek immediate medical
