Consistency is key for producing high-quality, integrally colored concrete. But sometimes mistakes happen, or blemishes occur due to damage during shipment, installation, or by mistakes from other trades. Matching colors for patching or other necessary repairs can be a difficult endeavor, and if not done properly, can leave buildings with eye-catching imperfections. Corrective concrete staining beautifies the finished product, saves replacement costs, and has even eliminated pending arbitration between contractors, suppliers, building owners, and architects on major new commercial concrete construction projects in the UK, Dubai, Canada, and the US.
