Renew-Crete Spray Coat
Spray Coat is a ready to use co-polymer modified resurfacing compound especially formulated to bond to almost any porous concrete surface. Due to its high strength and easy workability, Spray Coat is perfect to repair rain damaged slabs, scaling or dusting concrete, low spots or damaged steps, curbs as well as facing foundations. Spray Coat can be applied from a feather edge up to 1/2″ thick. Spray Coat can be broomed, sprayed or trowel finished.
The concrete surface must be clean and free of all loose material, oil residue and have no sealers or paints. Clean thoroughly by using a pressure washer with a degreaser or stripper if necessary. Etch the surface using 1 part muratic acid to 2 parts water. Neutralize with an ammonia or baking soda and water solution, rinse thoroughly and allow to dry.
In a clean 5 gallown pail measure 1 1/3 gallons of clean water (and add color pack at this time). Using a dripp with a mixing wand, slowly add the dry Spray Coat to the water as you are running the mixing wand. Once you have added all the material, continue to mix thoroughly for 2 minutes to a plastic consistency with no lumps. For smaller portions use enough water to mix to a plastic consistency.
Patch & Leveling
Start by misting the surface with water, (surface should be damp only, no standing water) and then apply the Patch-It compound. Screed where necessary, smooth with a round edged fresno or pool trowel, keeping all tools clean and moist, and finish as desired. If the area to be patched is thicker that 1″, two or more applications may be necessary. Wait until the first application is dry, (1-3 hours) and then reapply.
Using a steel trowel or a squeegee apply an even coat of the desired color Spray Coat about 1/16″ thick. Allow to dry before continuing.
Using a hopper gun and an air compressor set at around 20 pounds, shoot the top coat of Spray Coat material. Before the material sets all the way, pass a pool trowel across the surface creating flats as you go along.
After the surface is completely dry, lightly scrape the deck with a flat floor scraper. Blow off any debris and seal. Toll or spray 2-3 coats of Renew-Crete Hi-Gloss Sealer. Allow 24 hours for foot traffic and 48 hours for auto traffic.
