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.

Mixing
Add 4.5 – 5.0 pints (depending on desired consistency) of clean water per 50 pound bag of material. Mix with a low speed drill. Add recommended amount of clean water into the container, followed by slowly adding the REPCON® H powder. Mix 3 minutes. Mix only what can be applied within the setting period.

REPCON® H can be applied in applications from 1/4” to 2” in a lift.

Deep Applications: For repair applications over 2”, REPCON® H should be extended with clean, SSD, 3/8” aggregate up to 60% by weight (30 lbs) and mix an additional 2 minutes. This extension will add approx 0.17 cu-ft to the unit yield and should be placed within 20-30 minutes.
Extended mixes will depend on the gradation of the aggregate but normally will reduce compressive strength by 500 psi.

Placement
: Trowel, or screed REPCON® H firmly into the prepared area, ensuring intimate contact with the bonding surface. Finish REPCON® H level with the surrounding concrete and allow to take an initial set. After the initial set, when REPCON® H is surface hard, finish by hand
trowelling.

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. Lightly spray SpecFilm as a finishing aid on this and any other polymer modified mortars to assist in finishing. REPCON® H is self-curing under most conditions. In severe drying conditions, use an ASTM C-309 compliant, water based SpecChem curing compound.
