Hiring and Process Guide
What Should Professional Paver Sealing Include?
A professional proposal should describe the complete process—not reduce the job to spraying sealer on a driveway.
Written and reviewed by HydroSeal’s Trident Master Certified paver-sealing team serving selected Northeast Florida communities.
Quick answer: Professional paver sealing should include an inspection, measured scope, cleaning and surface preparation, stain and coating evaluation, joint-sand assessment, adequate drying, a compatible sealer applied at the correct rate, protection of adjacent areas, and written cure and maintenance instructions. Repairs, stripping, stain treatment, and complete sand replacement should be identified separately when needed.
The quality of a sealing project is usually determined before the sealer is opened. A strong coating cannot compensate for trapped moisture, dirty pores, unstable joints, incompatible old sealer, poor drainage, or rushed application.
The professional paver-sealing checklist
| Stage | What should be included | Why it matters |
|---|---|---|
| Inspection | Surface type, old coating, drainage, movement, stains, joints, and access | Determines whether the project needs cleaning, resealing, repairs, or stripping |
| Measurement | Actual square footage and identified work areas | Prevents vague pricing and scope disputes |
| Cleaning | Appropriate pressure, chemistry, dwell time, agitation, and rinsing | Removes contamination without unnecessary surface damage |
| Preparation | Residue removal, stain treatment, old-coating evaluation, and repairs | Creates a surface the selected sealer can bond to |
| Joint sand | Depth and condition assessment, replenishment or replacement as specified | Supports joint stability and a uniform finished appearance |
| Drying | Weather and moisture evaluation rather than a fixed clock alone | Reduces whitening, blushing, adhesion failure, and trapped moisture |
| Sealing | Named product or system, controlled coverage, proper coats, and traction planning | Matches protection and appearance to the surface |
| Aftercare | Foot, furniture, vehicle, irrigation, and cleaning restrictions | Protects the coating during cure |
Inspection should come before price
A contractor should be able to explain whether the pavers are concrete, clay, travertine, or another material; whether an existing topical coating is present; and whether the joints, drainage, and surface condition support the proposed process. Photos can help, but measurements and an on-site evaluation are often necessary for failed sealer, moisture problems, repairs, or stripping.
Cleaning is more than high pressure
Professional cleaning matches pressure and chemistry to the surface. Excessive pressure can remove too much joint sand, scar softer pavers, expose aggregate, or damage an old coating. Weak cleaning can leave organic growth, oils, minerals, detergent, or old coating residue that interferes with the new sealer.
Homeowners should also understand the limits. Some oil, rust, fertilizer, tannin, irrigation, silicone, efflorescence, and coating defects cannot be completely removed. A professional scope should describe treatment and expected improvement without guaranteeing a perfect result.
Joint sand should be condition-based
Not every project needs every grain of sand removed. Some joints need replenishment after cleaning. Others contain contaminated, hardened, poorly graded, or incompatible material that needs more extensive removal. HydroSeal commonly installs ASTM C144 kiln-dried joint sand where appropriate, but the correct scope depends on joint condition and the sealer system.
The sealer must match the surface
“Wet look,” “natural look,” “water based,” and “solvent based” are not complete specifications. The contractor should consider porosity, existing coating compatibility, moisture, traffic, traction, joint stabilization, coastal exposure, desired sheen, and future maintenance. HydroSeal uses contractor-grade Trident systems when appropriate, including Hurricane CAT 5 for selected enhancing and joint-stabilizing applications and Break Wall for selected natural-look penetrating applications. Neither is universal.
Written cure guidance is part of the job
Typical HydroSeal guidance may include keeping foot traffic off for about 24 hours, furniture off for 24 to 48 hours, vehicles off for 48 to 72 hours, and irrigation off for about 48 hours. Product, weather, shade, surface, and project conditions can change those windows, so the instructions provided for the actual job control.
Before hiring, compare the process using the contractor-selection guide and review whether the proposal clearly distinguishes routine sealing from cleaning, resealing, or stripping.
Frequently asked questions
Should joint sand always be replaced before sealing?
Not automatically. The joints should be inspected for depth, contamination, washout, hardening, and compatibility. Some projects need replenishment, while others need substantial removal and replacement.
Should pavers be sealed immediately after pressure washing?
Only when the product, surface, joints, weather, and measured moisture conditions allow it. In Florida, many projects need additional drying time after cleaning.
Does professional sealing guarantee every stain will disappear?
No. Cleaning and treatment can improve many stains, but permanent discoloration, embedded minerals, rust, oil, silicone, efflorescence, and old coating damage may remain.
