Georgia
Drive Windward Parkway on a bright afternoon and the pattern is obvious. South and west elevations along the GA 400 corridor have gone chalky, while the shaded sides have gone green. Alpharetta leans hard on brick fronts with synthetic stucco returns, hardboard trim and cedar shakes in the gables, and those are the assemblies that fail first. Humid summers feed mildew on north walls in Lake Windward, Nesbit Lakes, Glen Abbey and Park Brooke, and January freeze and thaw opens hairline cracks at window heads and stucco control joints. Near Milton Park and downtown, older painted wood carries film built up over decades of recoating. Rhino Shield answers the cracking directly. It is a ceramic coating that stays flexible after it cures, so it moves with a stucco return instead of splitting across it. Applied at a minimum of 10 to 12 mils over a prepped and primed wall, eight to ten times what a coat of paint leaves behind, it comes with a 25-year warranty that transfers with the deed.
