How to Seal a Block Paved Drive

However, over time, exposure to the elements and heavy usage can cause the paving and joints to become dirty, worn, and prone to weeds. Sealing the block paving not only enhances it’s visual appearance but also provides protection against stains, weed growth, and erosion. To ensure a successful sealing process, it’s essential to follow a systematic approach that includes cleaning, sanding, and sealing the joints. Begin by thoroughly scrubbing the paving and joints to remove any dirt, grime, or weeds. Once the surface is clean and dry, proceed to fill in any gaps or low spots with kiln-dried sand, ensuring it’s evenly distributed. Use a brush to meticulously work the sand into the joints, creating a solid, stable base. Finally, sweep off any excess sand and proceed to apply the sealant, paying close attention to even coverage and thorough saturation. The sealing process provides a protective layer that not only enhances the overall appearance of your block paved drive but also prolongs it’s lifespan, ensuring years of beauty and functionality.

How Do You Clean Block Paving Before Sealing?

Cleaning block paving before sealing is an essential step to ensure a smooth and effective sealing process. First, it’s recommended to use a pressure washer and a wire brush to clean the block paving thoroughly. This will help remove any built-up dirt, grime, and moss that may have accumulated on the surface. Be sure to pay special attention to the joints between the pavers to remove any debris.

After cleaning the block paving, it’s important to remove any weeds that may be growing between the pavers. These can be manually pulled out or treated with a weed killer, depending on the severity of the weed growth. Weeds not only affect the appearance of the paving but can also risk further damage if left untreated.

Once the block paving is clean and weed-free, it’s crucial to allow the area to dry completely before proceeding with the sealing process. This ensures that the sealer adheres properly to the surface and provides optimal protection. You can speed up the drying process by allowing the area to air dry or using a leaf blower.

Next, it’s advisable to use a broom to remove any loose bits of dirt or debris that may have been left behind after the cleaning process. This will provide a clean and uniform surface for the sealing.

Before applying the sealer, it’s recommended to refill the jointing gaps between the pavers. This can be done using kiln-dried sand, which is swept into the joints and then excess sand is brushed away. Properly filled joints not only enhance the appearance of the block paving but also prevent weed growth and maintain the stability of the paved area.

Is It a Good Idea to Seal Block Paving?

Sealing block paving is indeed a good idea for several reasons. Firstly, it provides a protective barrier that helps to prevent the growth of weeds and moss between the blocks. These unsightly intruders can quickly ruin the overall appearance of your paving and can be difficult to remove once they’ve taken hold. By applying a sealant, you can prevent them from taking root and keep your paving looking clean and well-maintained.

By creating a waterproof layer, it helps to prevent water from seeping into the joints and causing the blocks to become loose or unstable. This is particularly important in areas that experience frequent rainfall or frost, as waterlogged or frozen blocks can easily crack or shift over time.

Without a sealant, the surface of the blocks can gradually fade and become dull over time due to exposure to sunlight and other environmental factors. By applying a sealant, you can lock in the vibrant colors and keep your paving looking fresh and attractive for many years to come.
