Answer
How Do I Repair It?
If the damaged areas are small, the most popular answer is applying a liquid coating, much like a sealer, over the original surface. First, sweep and clean the product. You'll probably want to rent a power washer to remove any unwanted debris or peeling paint chips. If the façade is smooth, you'll also have to use an acid wash to rough up the surface for proper adhesion of the coating (the same process should be followed if you're thinking about painting light-colored decking with a darker shade). Once it dries, you're now ready to repair the area. You could of course do this yourself since Mortex Manufacturing Co., Inc. and other companies provide repair kits that cover 6 square feet (multiple kits can be purchased for larger areas). The repair kits are easy to use and come in a wide variety of colors to match your original shade (everything is included except a small trowel). But if you do not feel comfortable repairing the surface or if you have large areas to repair, you may want to contact a concrete contractor to apply it.
