Application

Surface Preparation: The concrete must be sound and free of all foreign material, including oil, grease, dust, laitance or other surface contaminants. For maximum durability, saw cut the perimeter of the repair 1/8” deeper than the depth of the repair, creating a notched, reinforced edge. Mechanically abrade the surface by an engineered approved method in accordance with ICRI 310.2 Guideline to a minimum CSP 5. All concrete surfaces to be repaired must be in a saturated-surface-damp (SSD) condition with no standing water on the surface.

Priming/Scrub Coat: Thoroughly clean all exposed steel reinforcing of rust and coat with SpecPrep SB.
Prepared concrete must be SSD and primed with a spray or brush coat of SpecPrep SB and the repair mortar applied wet on wet or up to the recommended open time (see SpecPrep SB technical data sheet).
As an alternative, apply a scrub coat of the properly mixed repair mortar by scrubbing a thin layer into the predampened substrate with a stiff brush. Place the repair mortar immediately before the bond coat dries.

Mix 4.75 – 5.25 pints (depending on desired consistency) of clean water per 50 pound bag of material.
Mix with a low speed drill or mortar mixer. Add recommended amount of clean water into the container, followed by slowly adding the RepCon® 928 powder. Mix 2-3 minutes. Mix only what can be applied within the setting period. Depending on the area dimensions, RepCon® 928 can be applied in applications from 1” to 6” in a lift without extension.

Deep Applications: For repair applications over 2”, RepCon® 928 can be extended with clean, SSD, 3/8” aggregate up to 60% by weight (30lbs) and mixed an additional 2 min. Choose a clean (free of organic material) wellgraded 3/8” aggregate. Aggregate should be predampened prior to mixing with RepCon® 928. The total mixing water for the batch shall be reduced by the amount of free water found in the aggregate. This extension will add approx 0.18 cu-ft to the unit yield and should be placed within 15-20 min.

Placement: Trowel, or screed RepCon® 928 firmly into the prepared area, ensuring intimate contact with the bonding surface. Finish RepCon® 928 level with the surrounding concrete and allow to take an initial set. After the initial set, when RepCon® 928 is surface hard, finish by hand trowelling. Excessive troweling is not required. Finishing/Curing: Finish the repair material to the desired texture to best match the surrounding concrete. Do not add additional water to the surface during finishing.
