Basic Use

Adi-Con BA AC Super modifier improves waterproofing, in- creases chemical resistance, allows thin section applications and slows down the carbonation of concrete and mortar. Adi-Con BA AC Super modified mortar and concrete are suitable for traf- fic toppings, patching and as leveling courses. The crack resis- tance and bond strength of thin set mortars, stucco and terrazzo are considerably improved with the addition of Adi-Con BA AC Super. It provides very high strength when used as bonding slurry with sand and cement. Values over 3 MPa in direct tensile pull-off test can be achived

Composition and Materials

Surface Preparation

Remove all loose, delaminated and oil contaminated concrete. Clean the surface by shotblasting, scarifying or a high pressure waterblasting (min. 24 MPa or 3,500 psi) to remove laitance, form release agents, dust, dirt and efflorescence. Acid cleaning is not recommended.

Crack Treatment

Any existing cracks must be treated separately

Mixing

Adi-Con BA AC Super modified mortar is easily mixed using a mortar mixer, or heavy duty drill (400-600 rpm) with a mixing paddle. Mix sand, cement and most of the water specified, before adding Adi-Con BA AC Super. Do not use air-entraining admixtures. Do not over mix to prevent high air content. Adjust the water to obtain the desirable consistency. Convey the mixed material to point of placement in clean, uncontaminated contain-ers.

Application

Saturate the surface with water for a minimum of six (6) hours. Remove all standing water to achieve a saturated surface dry condition. Apply a thin coat of the Bonding Slurry and place the Repair Mortar into the wet slurry. Keep wet edge. Do not over trowel or over finish. Provide a broom finish.

Curing

Moist cure for 24 hours and air dry cure for additional 3 days. Protect against rapid evaporation, or plastic shrinkage cracking could occur.

Clean Up

All tools must be cleaned with water immediately after use. Cured material can only be removed mechanically.
