If you have a new patio, you need to wait for at least 1 month before sealing it. Then, you have to pick the days with warm temperatures (around 50°F). Patio sealant needs dry conditions to make it settle completely and it takes at least 3 days to finish the process.

  • Use the weather apps on your phone and check for 3 consecutive days with the warm temperature and low humidity.

  • Mix water and detergent then pour the mixture onto the surface of the patio.
  • Scrub the paint stains and grease with a stiff brush. If you spot the stains that have penetrated the pores of the surface, you have to use muriatic acid. Be careful about dealing with this chemical, use a small amount first, and wear your safety gear.
