How We Clean Your Pavers
1. To clean the paver area, we begin using a commercial grade surface cleaner that has a rotating bar with 2 spray tips. This operates at 3500-4000 psi and will thoroughly scrub the pavers and paver joints without causing damage. We then "cross wash" the paver area again, so it gets "double scrubbed" to ensure they're clean, and to help remove algae buildup or dirty sand between the paver joints.
2. We then use a wand to pressure wash around all edges, corners, columns, etc. Pool areas also get detailed around the pool screen, pool coping, hot tubs, and other water features. The wand helps remove paint spots, mortar, grease, and more from the surface of your pavers.
Rinsing The Paver Area
3. After the washing process, we thouroughly rinse all dirt and debris from the paver area. Flusing the mold and algae from the paver joints is a key part of the rinsing process. Once the pavers are rinsed, it's time to re-sand all the paver joints.
Resanding The Paver Joints
4. Resanding the paver joints is very important, as the sand provides the stability of your entire paver system. We use a coarse-grained masonry sand and fill to within approximately 1/8" of the paver edge using the "wet sanding" method. Wet sanding is betther than sweeping because the wet sand settles to the lowest point and allows us to fill them properly and rinse away the excess.
5. Once the sanding of the paver joints is complete, we use a blower to blow any excess sand off the pavers before applying the sealer.
Applying The Sealer- Flood Coat
6. The first coat of sealer to be applied is called a "flood coat". The paver joints and surface of the pavers are actually flooded with sealer to ensure the sand absorbs the sealer, and that the paver itself gets soaked to create the barrier between your pavers and the elements. Getting the sealer deep into the paver helps bring out the true colors of your paver system, and keep them there.
Applying The 2nd Coat of Sealer
7. A second coat, or "top coat" is also applied to help form the protective barrier your pavers need, and to deliver more sealer to the paver joints. The 2nd coat adds another layer of protection helps give your paver system a hint of shine without becoming slippery or too shiny.
After the sealer fully cures, the sand will be fully locked into the paver joints, colors enhnaced, and long-lasting protection against the elements.
Finishing The Job
After the sealer is applied, we use a backpack blower to help disperse excess sealer and to help recoat the paver surface. We make sure to wipe down pool cage, sliding doors, track drains, etc. For driveways, we make sure that all dirt and debris is rinsed from sidewalks and curb areas.
Seal 'n Lock recommends waiting 24 hours to return furniture to patios, and 48 hours before driving vehicles on driveways or paver roadways.
