19 reactions | National Gypsum's Permabase cement board is perfect for outdoor projects. Stucco can be applied directly to the board, saving time and money. You can also use it to apply stone, brick or tile — think front-door surrounds, outdoor kitchens and fireplaces. (We sure are!) It also comes in an R-10 insulated version, which means increased energy savings for homeowners! | Today's Homeowner | Facebook
