The concrete surface must be clean and free of all loose material, oil residue, 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 4 parts water. Neutralize with an ammonia or baking soda and water solution, rinse thoroughly and allow to dry.
Mixing Instructions (45 pound unit)
In a clean 5 gallon pail measure 1 1/4 gallons of clean water. Using a drill with a mixing wand, slowly add the dry Patch-It 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.
Patching & 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 a more uniform surface is desired, coat the entire surface with Re-Coat.
Note: If the area to be patched is thicker than 1″, two or more applications may be necessary. Wait until the first application is dry, (1-3 hours) and then reapply.
