DESCRIPTION
CPD ® Rapidcrete is a ready-to-use, fast setting, high strength patching material. It is non-metallic, non - staining, and non-toxic. CPD ® Rapidcrete can be used for both interior and exterior applications.
WHERE TO USE
CPD ® Rapidcrete is particularly useful when downtime is at a premium and where low temperatures do not allow ordinary cement based patching compounds to properly cure. The rapid hydration of this product allows moisture sensitive coatings such as polyurethanes to be applied to the patched area in 24 hours under normal conditions. Applications include repairing concrete floors in factories, warehouses, parking decks and ramps, loading dock areas and cold storage rooms, concrete bridge deck repairs and concrete runway repairs.
BENEFITS
• fast setting
• high strength
• excellent freeze-thaw resistance
• very low permeability
• high resistance to sulphate attack
• non-toxic
• chloride free

APPLICATION
Surface Preparation
The concrete substrate to receive the patching compound must be clean and sound. Square out the patch area minimum 12 mm ( ½") and chip out all contaminated concrete. Soak patch area with water so that the concrete is thoroughly damp (no free standing water should be present). For substrate temperatures below 10 ° C (50 ° F) use a slurry bond coat of CPD ® Rapidcrete and water. ® Concentrated Latex Adhesive, diluted 1:1 with water, can be mixed with CPD ® Rapidcrete powder to form a slurry bond coat mix. Scrub into the concrete then apply the mixed material as soon as possible . The mixed CPD ® Rapidcrete must be applied before the slurry bond coat sets.
MIXING
CPD ® Rapidcrete can be mixed with different quantities of water to yield a wide range of consistencies from trowel grade to pourable. This product can also be mixed with a dilute latex solution to improve certain physical properties if desired. As with all cementitious products, use only enough water to achieve the desired consistency. Do no exceed 5L (1.32 US gal) of water per 25 kg (55 lb) bag.
CPD ® recommends extending CPD ® Rapidcrete with an equal weight (or loose volume) of clean 10mm (3/8”) pea gravel for all patching over 32 mm (1 1/4") in depth.
CURING
Wet curing of all patches and exposed grout areas is required as specified below. Curing by application of a film forming curing compound is not recommended as a direct substitute for wet curing. Once the CPD ® Rapidcrete has set (the material has a patchy-like finish) which is usually 30-45 minutes after placing @ 20°C (70°F), the product must now be wet cured for a minimum of 1-2 hours. This can be achieved by keeping the applied product wet covered with a layer of water, or using burlap that is continually kept saturated with water. If neither of these curing methods are possible, contact your CPD technical representative.
