Why Coat Paver Stones?

Applying a sealer to paver stones offers several benefits:

• Protection Against Stains – Prevents oil, dirt, and spills from seeping into the stone.

• Weather Resistance – Shields against rain, snow, and UV rays, reducing fading and erosion.

• Enhanced Appearance – Deepens color and provides a glossy or matte finish, depending on the chosen sealant.

• Weed and Moss Prevention – Reduces weed growth and discourages moss from forming in joints.

• Easier Maintenance – Sealed pavers require less frequent cleaning and prevent deterioration.

When to Coat Paver Stones?

1. Timing for Initial Sealing

• New Paver Installation – Wait at least 30–60 days after installation to allow for settling and efflorescence (white chalky deposits) to surface.

• Concrete Pavers – Generally, sealing can be done after four weeks to let moisture fully escape.

• Clay Brick Pavers – These can be sealed sooner since they absorb less moisture.

2. Seasonal Considerations

The best time to seal pavers depends on climate conditions:

3. Signs That Pavers Need Resealing

• Water Absorption – If water soaks in rather than beading on the surface, the old sealer has worn off.

• Fading Colors – UV exposure causes pavers to lose their vibrant hues.

• Stains or Oil Spots – Increased staining means the protective layer is compromised.

• Weed Growth Between Joints – Indicates that joint stabilization has weakened.

• Pavers Feel Rough or Dry – A sign that the previous coat has degraded.

Most paver sealants last between 2 to 5 years, depending on climate and foot traffic

How to Coat Paver Stones: Step-by-Step Process

1. Gather the Necessary Materials

• Sealer (water-based or solvent-based)

• Pressure washer or garden hose

• Mild detergent or paver cleaner

• Broom or leaf blower

• Paint roller or sprayer

• Polymeric sand (if needed)

• Safety gear – gloves, mask, and protective eyewear

2. Clean the Pavers Thoroughly

• Remove Debris – Sweep or use a leaf blower to clear dirt and leaves.

• Wash the Surface – Use a pressure washer or hose to remove built-up grime.

• Apply Cleaner (if needed) – For tough stains, apply a mild detergent and scrub with a brush.

• Let the Pavers Dry Completely – This usually takes 24-48 hours; sealing over wet pavers traps moisture and causes hazing.

3. Reapply Joint Sand (If Needed)

• Check Joint Stability – If gaps have formed between pavers, refill them with polymeric sand.

• Sweep the Sand In – Use a push broom to spread it evenly into the joints.

• Compact the Sand – Lightly mist with water to activate the binding properties.

4. Choose the Right Sealer

• Matte Finish – Ideal for a natural look.

• Wet-Look Finish – Enhances color vibrancy and provides a glossy effect.

5. Apply the Sealer

• Select an Application Method

• Sprayer – Best for even coverage and large areas.

• Paint Roller – Provides control and avoids overspray.

• Apply the First Coat – Work in sections, applying a thin and even layer.

• Let It Dry – Allow 24 hours before applying a second coat (if needed).

• Apply the Second Coat (if necessary) – For added protection, apply a second thin layer.

6. Allow Proper Drying Time

• Avoid Foot Traffic – Keep the area clear for at least 24-48 hours.

• No Heavy Objects – Wait 72 hours before placing furniture or driving on sealed pavers.

• Monitor for Proper Curing – Full curing can take up to 7 days.

Common Mistakes to Avoid

• Sealing Too Soon – Traps moisture and causes a hazy appearance.

• Applying Too Much Sealer – Leads to a sticky, uneven finish.

• Not Cleaning Pavers Properly – Dirt and stains will be locked in under the sealer.

• Skipping the Drying Step – Moisture under the sealer can cause bubbling and discoloration.

• Using the Wrong Sealer – Not all sealers work on every paver type; check manufacturer recommendations.

Maintaining Sealed Pavers

To extend the life of your paver sealant:

• Clean Regularly – Sweep and rinse every few weeks to prevent buildup.

• Spot Treat Stains Quickly – Use mild soap and water to remove spills before they set in.

• Avoid Harsh Chemicals – Acid-based cleaners can degrade the sealant.

• Reseal When Needed – Check every 2-3 years to determine if a new coat is necessary.

Coating paver stones is an essential step in preserving their appearance and durability. Choosing the right time and method ensures long-lasting protection and a professional finish. By following this guide, you can keep your outdoor space looking pristine while preventing damage from weather, stains, and wear.
