This Hot Job! was sent to us by Ryan at Monarch Construction in Temecula, California. Here are before and after photos of an interior office in Los Angeles. This office space is 3500 square feet up on the 22nd floor. Ryan and his crew had to grind off an existing and failing sealer to expose the existing concrete. Then they installed TC-2 with Water-Based Stain in Mahogany and Onyx and then sealed with SC-65 Water-Based Polyurethane Sealer.
