The Ultimate Guide to Block Paving Sealer: Benefits and Application

The Ultimate Guide to Block Paving Sealer is an essential product for anyone looking to maintain and enhance the appearance of their paved areas. Whether you have a driveway, patio, or garden path, applying a block paving sealer can provide a range of benefits that will keep your surfaces looking their best. This guide will walk you through everything you need to know about block paving sealer, from its benefits to the application process.

What is Block Paving Sealer?

Block paving sealer is a liquid product applied to paved surfaces to protect them from various elements and wear and tear. It forms a protective layer on the surface of the paving blocks, which can help to prevent damage from weather, stains, and general use. There are different types of sealers available, including acrylic, polyurethane, and water-based options, each offering unique benefits.

Benefits of Using Block Paving Sealer

1. Enhanced Appearance

Applying a sealer to your block paving can significantly enhance its appearance. The sealer brings out the natural colors of the paving blocks, giving them a vibrant and fresh look. It also adds a subtle sheen to the surface, making it look clean and well-maintained.

2. Protection from Stains

Block paving sealer provides a protective barrier that helps to prevent stains from penetrating the surface. This is particularly useful for driveways and patios where spills from vehicles, barbecues, or outdoor dining can cause unsightly stains. The sealer makes it easier to clean up spills before they have a chance to cause permanent damage.

3. Weather Resistance

Sealing your block paving can protect it from the effects of weathering. The sealer prevents water from penetrating the surface, reducing the risk of frost damage in colder climates. It also protects against UV rays, which can cause fading and discoloration over time.

4. Weed and Moss Prevention

A good block paving sealer can help to prevent weeds and moss from growing between the paving blocks. The sealer fills in the tiny gaps where weeds and moss typically take root, making it harder for them to establish themselves.

5. Extended Lifespan

By protecting the paving from various forms of damage, a block paving sealer can extend the lifespan of your paved areas. This means you won’t have to worry about replacing or repairing your paving as often, saving you time and money in the long run.

6. Easier Maintenance

Sealed block paving is easier to maintain. The protective layer makes it simpler to sweep away dirt and debris, and routine cleaning becomes less labor-intensive. This helps to keep your paved areas looking great with minimal effort.

Types of Block Paving Sealer

1. Acrylic Sealers

Acrylic sealers are popular for their affordability and ease of application. They provide a good level of protection and enhance the appearance of the paving. However, they may require reapplication more frequently compared to other types.

2. Polyurethane Sealers

Polyurethane sealers offer superior durability and long-lasting protection. They are more resistant to wear and tear, making them ideal for high-traffic areas like driveways. These sealers tend to be more expensive but are worth the investment for their extended lifespan.

3. Water-Based Sealers

Water-based sealers are environmentally friendly and easy to apply. They provide good protection and are safe to use around plants and pets. They are also less likely to cause discoloration compared to solvent-based options.

How to Apply Block Paving Sealer

Step 1: Preparation

Before applying the sealer, it is crucial to prepare the surface properly:

  1. Clean the Paving: Remove all dirt, debris, and weeds from the surface. Use a pressure washer for a thorough clean and allow the paving to dry completely.
  2. Repair Damage: Check for any damaged or loose blocks and repair them before sealing. This ensures a smooth and even finish.

Step 2: Choosing the Right Sealer

Select the appropriate sealer based on your specific needs and the type of block paving you have. Consider factors such as durability, appearance, and environmental impact.

Step 3: Application

  1. Read Instructions: Always read and follow the manufacturer’s instructions on the sealer product.
  2. Apply Evenly: Use a sprayer, roller, or brush to apply the sealer evenly across the surface. Be sure to cover all areas thoroughly.
  3. Multiple Coats: Depending on the product, you may need to apply multiple coats. Allow each coat to dry according to the manufacturer’s recommendations before applying the next one.
  4. Drying Time: Allow the sealer to dry completely before using the paved area. This can take anywhere from a few hours to a couple of days, depending on the sealer and weather conditions.

Step 4: Maintenance

To maintain the effectiveness of the sealer, regular maintenance is essential:

  1. Regular Cleaning: Sweep and wash the surface regularly to keep it free from dirt and debris.
  2. Reapplication: Depending on the type of sealer, reapply every 2-5 years to maintain protection and appearance.

Common Mistakes to Avoid

  1. Skipping Preparation: Failing to properly clean and repair the paving before sealing can lead to poor results and reduced effectiveness.
  2. Overapplication: Applying too much sealer can cause a glossy, uneven finish that may become slippery when wet.
  3. Incorrect Sealer Choice: Using the wrong type of sealer for your paving can result in inadequate protection and potential damage.
  4. Ignoring Weather Conditions: Sealing in unsuitable weather, such as rain or extreme temperatures, can affect the curing process and final outcome.


Using a block paving sealer is a straightforward and effective way to protect and enhance your paved areas. By choosing the right sealer and applying it correctly, you can enjoy the benefits of a beautiful, durable, and low-maintenance surface. Remember to regularly maintain the sealed surface to prolong its lifespan and keep it looking its best.
