COLOR AND SEALER TOUCH-UP (prices vary, $200 minimum): If your Carvestone’s color fades or disappears in areas, it probably just needs cleaning or re-sealing. If these won’t help, there are a few likely causes: pool chemicals, oil- or acid-based cleaners, landscape treatments, hard water, excessive power washing, or minerals or ground moisture moving up through your slab. Any of these may be giving your Carvestone a “stripped,” cloudy, or white appearance. While color and sealer are not under warranty, such issues can usually be improved or reversed through relatively inexpensive treatments including xylene baths, gloss restoration, color restoration, and/or re-sealing. When it’s time to reseal, keep in mind that we can also provide color restoration at a discounted price in combination with a full resealing.
