The answer to 'how to maintain patio' is to regularly clean, seal, and repair your patio to keep it looking its best. Start by sweeping or blowing off any debris, dirt, or leaves on the surface. Then, use a patio cleaner or mild detergent and a scrub brush to remove any stains or grime. Rinse the patio thoroughly with a hose. Once it's clean, you should apply a sealant every 1-2 years to protect the surface from weathering and damage.
If you notice any cracks, chips, or uneven areas, you'll need to make repairs. Small cracks can be filled with a concrete patching compound, while larger issues may require professional help. It's also a good idea to check for any loose pavers or bricks and re-secure them as needed. With regular maintenance, you can keep your patio looking great for years to come.
