You should wait until your pavers have completely dried and cured before pressure washing them. Wait at least three to five days, though some sealants may need up to an entire week. Rushing that timeline can mess with the finish, weaken the seal, or leave streaks that are tough to fix. Once the sealant has fully set, stick to a gentle approach. Keep the pressure under 1,500 PSI and hold the nozzle at least two feet from the surface. Anything stronger or closer can blast the joint sand loose or wear down the sealant you just applied.

Stamped concrete is durable and relatively easy to maintain. Regular maintenance includes sweeping away debris to keep it clean and prevent staining. It is also important to repair any cracks promptly to maintain its appearance and longevity. The concrete should be resealed every 2 to 4 years to protect the surface.

The ideal frequency for pressure washing depends on the surface being cleaned and your local environmental conditions. For a home's exterior with siding that is safe to wash (such as vinyl, cement, or aluminum), a full wash once or twice a year is a good guideline to remove accumulated dirt, grime, mold, and mildew. You may need to wash more frequently if you live in an area with heavy rain or snow, near a dirt road, or if you notice excessive buildup. Other surfaces have different schedules; for example, a frequently used driveway may need cleaning more often, while outdoor patio furniture might only need to be washed every few years. Use your discretion based on how dirty the area gets.

Yes, pressure washers can remove rust stains from concrete. However, when coupled with an acid treatment, they can be even more effective. Just be sure to use a minimum of a 15-degree nozzle to prevent damage to the surface, and users must also be careful not to get in the way of the pressure washer’s jet as they can cut through skin and cause injury.
