How to Resurface Concrete with Re-Cap

although concrete is one of the most durable building materials available time traffic and exposure to the elements can cause the surface to spall wear and discolor quikrete recap concrete resurfacer can provide a new durable wear resistant surface to old worn concrete driveways sidewalks and patios that will last the life of your concrete the crete recap concrete resurfacer will renew your concrete surface at a fraction of the cost to tear out and replace old concrete slabs as with any concrete repair project proper surface preparation is essential for a successful result this is especially true when resurfacing concrete old concrete must be rigorously cleaned to ensure proper adhesion of the new surface a high strength 3500 psi pressure washer must be used to remove any dirt oil grease or deteriorating concrete prior to recaps application recap is ideal for resurfacing large areas like driveways patios and pool decks but because it sets quickly it is important to section off your work areas to no larger than 144 square feet this will allow enough time for placing and finishing the resurfacer before it begins to set with this project it is essential that control joints and expansion joints are maintained to allow for slab movement these joints can usually be used to define your work area weather stripping or duct tape can be used to prevent recap from spilling into the joints before resurfacing your slab deeply spalled areas in large cracks should be repaired using recap that has been mixed to a trowelable consistency the repairs should be allowed to harden before resurfacing the entire area to mix recap a five-gallon bucket and a half-inch drill and paddle mixer should be used larger quantities can be mixed using a mortar mixer when working with any cement based mix it is important to wear safety glasses and waterproof gloves first measure and add two and a half to three quarts of clean cool water to the five gallon bucket to mix one forty pound bag of recap then begin to add the powder to the water while mixing mix for about five minutes until a lump free horrible consistency is achieved if the mix is too thick add water sparingly to reach the consistency of syrup if the mix is too thin additional powder can be added [Music] one 40-pound bag of recap covers about 90 square feet an eighth of an inch thick so a typical 16 foot by 24 foot driveway will use about five bags of recap and because the application process is continuous it is always best to have a few extra bags to allow for any changes in thickness or waste prior to applying recap saturate the surface of the concrete with water make sure to remove any standing water concrete acts like a rigid sponge dampening the concrete will cool the slab and prevent the mixing water from being drawn out of the material during application and curing you are now ready to begin the application process pour the recap onto the concrete in one foot wide strips then using a long-handled squeegee scrub the material into the concrete surface and then working back and forth evenly spread the recap onto the slab within about five minutes a non-slip finish can be applied using a concrete broom make full strokes across the full distance of the work area without stopping all broom strokes should be made in the same direction for uniformity of appearance a concrete edging tool can also be used within about 20 minutes of pouring the recap recap has a working time of about 20 minutes at 73 degrees in hotter weather the working time will be reduced using cold mixing water and keeping the bags of recap shaded will help extend the application time under normal conditions no special curing is required in temperatures over 90 degrees moist cure with a fine water mist for 24 to 48 hours because quikrete recap concrete resurfacer is polymer modified temperatures should remain above 50 degrees for at least eight hours and should be protected from freezing for 24 hours after applying recap will support foot traffic in about 8 hours and vehicle traffic in 24 hours quick crete recap concrete resurfacer [Music]
