Sanding and Sealing Pavers: Step-by-Step Guide

Paver patios, walkways, and driveways can last for decades when they receive proper care; sanding and sealing pavers should absolutely be part of this care.

Paver Upkeep: Why It Matters

Sanding and sealing pavers protects both their appearance and structural integrity. Adding paver joint sand helps lock pavers together, preventing shifting and reducing weed growth between pavers. Sealant adds a protective layer that resists moisture, stains, and fading from sun exposure.

How to Sand and Seal Pavers in 5 Steps

Step 1: Clear & Clean the Area

Clear the area of furniture and other object. Then sweep away debris with a broom or leaf blower before washing the area (with a a pressure washer or garden hose) to attack dirt, grime, moss, or mildew. Let the pavers fully dry.

Step 2: Add Your Joint Sand

Sweep polymeric sand into paver joints until the gaps are completely filled.

Step 3: Activate Your Joint Sand

Lightly mist the surface with water to activate the bonding agents in polymeric sand; avoid using too much water, which can wash the sand out of the joints.

Step 4: Add Your Sealant

Once the sand has set and the surface is dry, apply a paver sealant using a sprayer or roller.

Step 5: Let Everything Cure

Allow the sand and sealant to cure according to the manufacturer's instructions. Most sealants require 24 to 48 hours before the surface can handle foot traffic or outdoor furniture.

Considerations Before Getting Started

DIY vs Professional Paver Cleaning

Some homeowners choose to clean, sand, and seal pavers themselves. However, large patios or heavily stained surfaces may require specialized equipment and experience.

Type of Paver Sealant Used

Sealants come in different finishes; some enhance the natural color of the pavers, while others create a more subtle protective layer.

Type of Paver Sand Used

Polymeric sand contains binding agents that harden when activated with water, adding stability to paver driveways, patios, and walkways. Standard joint sand can also be used, but it may wash out more easily over time.

Sanding & Sealing Pavers FAQs

Do you seal pavers before or after sanding?

Joint sand should be installed before applying a sealant. The sand stabilizes the pavers and fills the joints, while the sealant locks everything in place and protects the surface.

What is the average cost to seal pavers?

The average cost to seal pavers typically ranges from $3 to $5 (by sq. ft.) for professional services.

Can you seal pavers yourself?

Yes, many homeowners seal pavers as a DIY project. However, proper cleaning, sanding, and sealant application are important to avoid streaks, uneven coverage, or trapped moisture.

What is polymeric sand?

Polymeric sand is a joint sand that contains polymers and bonding agents. When activated with water, these materials harden to lock pavers together while reducing weed growth and insect activity.

How long after activating polymeric sand can you seal pavers?

Most manufacturers suggest waiting between 24 to 72 hours after activating polymeric sand before applying a sealant. This waiting period allows the sand to fully harden and set between the pavers.

What is a paver sealer?

A paver sealer, as the name implies, is a protective coating for paver surfaces. It helps resist moisture, stains, fading, and weather-related damage.

How often should I be resanding and resealing pavers?

Most paver surfaces benefit from sanding and resealing every three to five years, while high-traffic areas or surfaces exposed to heavy weather may require more frequent maintenance.

How do I prepare pavers for sanding and sealing?

Preparation for sanding and sealing pavers involves removing debris, deep cleaning the paver surface, and allowing the pavers to dry completely. Any missing joint sand should be replaced before sealing occurs.

Refreshing Your Pavers

Routine maintenance like cleaning, joint sanding, and sealing pavers helps ensure these outdoor surfaces look and perform well for years to come.
