Color Staining a Concrete Floor
Project: Storm-Ready Design, Episode 8, Part 1
Bob reviews storm-ready features and visits with the homeowners and Tom Moorad of Moorad Painting as he applies a proprietary concrete staining product that will complement the Porcelanosa metallic-look tiles inside. This stain is dripped on, spread with a squeegee to avoid pooling, and topped with a clear coat sealer to give a long-lasting color finish. Joe Breese from Alcoa and Leslie-Chapman Henderson from FLASH join Bob for the vinyl soffit panel installation. Soffits are a major cause of roof failure and water intrusion during hurricanes, so this home has a reinforced soffit construction to tie it to the building walls and enhanced construction to make the panels grip tighter during high winds rather than pull apart. These panels channel air through grooves and provide 80 percent more ventilation than traditional vinyl panels. Bill Zoeller and Lance Keeling explain the energy efficiency measures that will save the home $100 per month in operating expenses like low-e glass that blocks up to 70 percent of solar heat gain, insulation in the concrete walls to prevent heat transfer, air conditioning ducts that are dropped in the attic floor and insulated with soy-based foam, and a 14 SEER heat-pump air conditioning unit.
- Part 1: Color Staining a Concrete Floor
- Tom Moorad joins Bob to show how his proprietary technique and product for color staining concrete is applied. He explains that the concrete slab should first be etched then treated with a mineral acid -- not muriatic acid, as that is too strong and will degrade the acrylic stain that goes on the surface. This is called “shocking the substrate”. Moorad then applies the stain with a hand pump.

- Part 3: Building an Energy-Efficient Florida Home
When hurricanes strike again and again, as they did in Florida in 2004, the effects are devastating. Bob Vila and crew work to completely rebuild a damaged house, using new standards for storm-ready housing. Along the way, Bob investigates a home's vulnerabilities in extreme weather and learns why some building systems fail and others succeed.
