Does block paving need to be sealed?

Question

Someone mentioned sealing extends its life. Is it something you really need to do, and how often?

Cleaning block with a power wash takes the sand out so once cleaned you must re sand the driveway then seal the driveway . yes this will extend the life if it was laid properly entitally i would say every 6 months maximum every 12 months then it will protect the driveway thanke Benjamin

Hi Elly. Once the blocks have been sanded and compacted it is wise to seal the area. . It won't change the colour of the blocks but will harden the kiln dried sand and help protect the joints from any seeds that could germinate within the joints. Use a wrll k own sealant and not a basic cheap one. It really does make a difference. I hope this information is helpful for you ? 
Thank you.

Blerim · Answer

Sealing block paving isn’t essential, but it is recommended. A quality sealer helps protect against stains, weeds, algae, and colour fading while extending the life of the paving. Most sealers last 3–5 years before reapplication is needed.

John · Answer

Block paving does not have to be sealed, provided it has been installed correctly on a suitable sub-base and with kiln-dried sand brushed into the joints.

However, sealing can offer a number of benefits, including:
• Enhancing and maintaining the colour of the paving
• Helping to reduce staining from oil, dirt, and algae
• Slowing down weed and moss growth
• Protecting the surface from general weathering

We normally recommend waiting at least 3-6 months after installation before applying a sealant, as this allows the paving to settle properly and any natural salts to disperse.
