The answer to 'how to maintain paver' is to regularly clean, seal, and repair pavers to keep them looking their best. This includes sweeping away dirt and debris, applying a protective sealant every 2-3 years, and addressing any cracks or uneven pavers promptly.
Start by thoroughly sweeping the paver surface to remove any leaves, dirt, or other buildup. You can also use a garden hose or pressure washer to clean the pavers, but be careful not to damage the surface. Once clean, inspect the pavers for any cracks, chips, or uneven areas. Use a paver joint sand or polymeric sand to fill in any gaps between the pavers.
