The amount of concrete required for a 10-by-10-foot slab is determined by the slab's diameter. A 4-inch slab requires either eight 60-pound or six 80-pound bags, while a 6-inch slab requires either 12 60-pound or nine 80-pound bags. The weight of the bag varies depending on the type of concrete that is used. As with any project that involves concrete, durability and longevity are factors to consider when selecting a color for your driveway or patio. The best way to ensure that you get the look you want over time is to choose an oil-based paint. These types of paints resist heat and sunlight better than latex paints, so they last longer. If you'd like to add a touch of green to your driveway or patio, consider using grass clippings as mulch. This will help retain soil moisture and create a more natural look while also reducing cleaning costs! Concrete is a very durable material and can last for decades with proper maintenance. As long as you don't walk in the wet area or use the pool as a bathroom, your concrete floor will remain looking new for quite some time. Regular washing of your driveway or patio will keep it looking newer for longer. The best way to keep concrete clean is with a power washer. A gentle rinse under a faucet should be enough to clean off any dust or debris before you start building again.
