Why Remove Paver Sealer?

Paver sealer, while initially protecting your paving stones, can eventually wear down, fade, or become damaged. This can leave your pavers looking dull, uneven, or even stained. Removing old sealer is crucial before resealing to ensure proper adhesion and a longer-lasting finish. Removing the old sealer is also necessary if you're planning on changing the color or type of sealer you use.

Assessing Your Pavers and Choosing a Method

Before starting, inspect your pavers. Note the type of sealer used (water-based or oil-based), the extent of the damage, and the size of the area. This will help determine the best removal method.

Identifying the Sealer Type

Knowing whether your sealer is water-based or oil-based is vital. Oil-based sealers are more durable but also tougher to remove. Water-based sealers are generally easier to work with. Check the original product label or consult with a paving professional if uncertain.

Methods for Removing Paver Sealer

Several methods exist for removing paver sealer, each with its pros and cons:

1. Chemical Strippers

Pros: Effective on stubborn oil-based sealers. Cons: Can be harsh, requiring safety precautions (gloves, eye protection, ventilation). May require multiple applications.

How to Use: Follow the manufacturer's instructions carefully. Apply the stripper evenly, let it dwell according to the instructions, then scrub with a stiff-bristled brush. Rinse thoroughly with water.

2. Pressure Washing

Pros: Efficient for large areas, removes loose sealer effectively. Cons: Can damage pavers if used improperly (too high pressure). May not remove all sealer residue. Requires a pressure washer.

How to Use: Use a pressure washer with a wide-angle nozzle. Maintain a safe distance from the pavers. Start with a lower pressure setting and gradually increase if necessary. Work in sections, rinsing frequently.

3. Mechanical Methods (Grinding or Sandblasting)

Pros: Excellent for removing very stubborn sealer. Cons: Very aggressive methods, potentially damaging pavers if not done carefully by a professional. Can create a lot of dust and debris. Generally requires specialized equipment and expertise.

4. Manual Scrubbing (for small areas and light sealer)

Pros: Environmentally friendly, inexpensive. Cons: Labor-intensive, only suitable for small areas with light sealer buildup.

How to Use: Use a stiff brush and a cleaner appropriate for the sealer type. Scrub vigorously and rinse thoroughly with water.

Step-by-Step Guide to Stripping Paver Sealer

Prepare the Area: Clear the area of any furniture, plants, or debris. Protect surrounding areas with plastic sheeting if necessary.
Choose Your Method: Select the method best suited to your pavers and sealer type.
Apply the Stripper (if using): Follow the manufacturer's instructions precisely. Ensure adequate ventilation.
Scrub and Rinse: Use a stiff-bristled brush to scrub the pavers. Rinse thoroughly with water, ensuring all residue is removed.
Pressure Wash (if using): Use a pressure washer to remove any remaining sealer. Keep a safe distance and use a wide-angle nozzle.
Inspect and Repeat: Inspect your pavers. If necessary, repeat the process to ensure all sealer is removed.
Clean Up: Dispose of all chemicals and debris properly according to local regulations.

Safety Precautions

Wear protective gear: Gloves, eye protection, and a respirator are crucial, especially when working with chemical strippers.
Work in well-ventilated areas: Chemical strippers can release harmful fumes.
Follow manufacturer's instructions: Always follow the instructions on any chemical products you use.
Test in an inconspicuous area: Before applying any stripper to the entire area, test it on a small, hidden section of pavers to ensure it doesn't damage them.

Post-Stripping Care

After removing the sealer, allow the pavers to dry completely before resealing (if desired). Sweep or vacuum up any remaining debris.

By following these steps and choosing the appropriate method, you can successfully strip sealer from your pavers, leaving them clean and ready for their next phase. Remember safety is key! If unsure about any aspect of the process, consult a paving professional.
