Frequently Asked Questions: Power Washing & Paver Restoration
1. What is PT702 Surface Coatings' process for power washing and restoring pavers?
At PT702 Surface Coatings, we follow a thorough, multi-step restoration process tailored to whether your pavers are unsealed or have an existing coating:
- Step 1: Pre-Inspection. We walk the property with you to check for loose pavers, joint sand levels, drainage issues, stubborn stains, existing sealer condition, and surrounding landscaping that needs protection.
- Step 2: Water Recovery Berm Setup. Before turning on any water, we place containment berms around the work area to capture, filter, and safely recover runoff water.
- Step 3: Surface Prep & Stripping (If Needed). If your pavers have an old, failing, or hazy sealer, we apply an eco-friendly stripper to safely break down and lift the existing coating without harming surrounding plants or hardscapes. (For unsealed pavers, we move straight into deep cleaning and prepping the surface for SB-8700.)
- Step 4: Deep Surface Cleaning. Using commercial rotary surface cleaners and controlled pressure, we lift dirt, grime, and stripped sealer residue evenly without etching or damaging the pavers.
- Step 5: Drying & Optional ASTM C144 Joint Sand Installation. Once the pavers are completely dry, we can install fresh, washed ASTM C144 joint sand if your joints are low or washed out. If your existing joint sand is still intact and level, we can skip re-sanding and move straight to sealing.
- Step 6: SB-8700 Solvent Sealer Application. On clean, dry, unsealed pavers, we apply SB-8700 solvent-based sealer to penetrate the surface, enhance color, and—when fresh sand is installed—bind the ASTM C144 sand together into a rock-solid barrier.
- Step 7: Final Walkthrough. We remove our containment berms, clean up the site, and inspect the finished work with you to ensure complete satisfaction.
2. Do you offer ongoing maintenance plans to keep my pavers looking great?
Yes! PT702 Surface Coatings offers a regular maintenance cleaning program every 3 to 4 months at a special discounted rate. Routine washings clear away desert dust, windblown debris, and early surface buildup before they can stain or wear down your sealer—extending the life of your SB-8700 finish and keeping your outdoor spaces spotless year-round.
3. Do my pavers always need new joint sand?
No—re-sanding is completely optional and depends on the current condition of your paver joints. During our pre-inspection, we will check whether your existing sand is still full and stable. If your joints have washed out, settled, or had weeds removed, we recommend adding ASTM C144 joint sand so the SB-8700 sealer can lock them back in place. If your joints are already in great shape, we can clean and seal right over them.
4. What if my pavers already have an old or peeling sealer on them?
If your pavers have a previous sealer that is flaking, turning white, or trapping moisture, applying new sealer over top won't work. In those cases, we use an eco-friendly stripper during the prep phase to safely dissolve the old coating. Coupled with our water recovery berms, we capture and remove the stripped residue cleanly so we can restore your pavers down to a fresh, unsealed surface ready for SB-8700.
5. Why do you use ASTM C144 joint sand and SB-8700 solvent sealer instead of polymeric sand?
Unlike polymeric sand—which can haze on paver surfaces or wash out over time in extreme heat—ASTM C144 sand paired with SB-8700 solvent-based sealer delivers superior joint stabilization. Applied directly to prepped, unsealed pavers, SB-8700 penetrates deep into the sand joints and hardens them from top to bottom while enhancing the rich color of your pavers and protecting them against intense UV rays, oil stains, and weed growth.
6. Why do you use a water recovery berm?
Water recovery berms keep dirty runoff, stripped sealer residue, and washed-out sand from flowing into storm drains, pools, or delicate desert landscaping. This keeps your property spotless and ensures PT702 Surface Coatings meets strict local environmental and water conservation standards.
7. How long does the paver restoration process take?
Most residential projects take 1 to 2 days to complete (projects requiring sealer stripping may take slightly longer depending on the number of existing coats). Deep cleaning and stripping happen first, while optional sanding and applying the SB-8700 sealer happen once the pavers are completely dry.
8. When can I walk or drive on my pavers after they are sealed?
Because SB-8700 is a fast-drying solvent-based sealer, you can typically walk on your pavers 2 to 4 hours after application. For vehicles and heavy patio furniture, we recommend waiting 24 hours so the sealer can fully cure.
9. How often should pavers be resealed in the Las Vegas climate?
Because of intense desert sun and UV exposure, we recommend professional resealing every 2 to 3 years. Pairing your SB-8700 seal with our 3-to-4-month maintenance cleanings keeps colors vibrant, prevents premature wear, and protects your investment long-term.
10. Do I need to move my patio furniture before you arrive?
Yes, please clear all furniture, planters, grills, and décor from the work area prior to our arrival. If you have heavy items you cannot move, let us know during the pre-inspection so our team can assist you.
