13 Sep Block Paving Maintenance And Sealing
Block paving is arguably the best option when considering to installing a driveway, walkway, path or patio in your home. It provides a natural look and is easy to maintain. Unfortunately, not many people know of the upkeep requirements that help ensure that the paved surface looks presentable and it in its best condition.
Sealing and adequate maintenance should be a factor worth having in mind when it comes to protecting your investment. Why pay lots of money to have the pavers laid only to let weeds, dirt, algae, lichen, moss, and grime take over?
As such, part of the maintenance effort start before installing the pavers where the area and pavers are pre-treated with a weed killer and a fungicidal wash. But this is a precautionary measure that needs adequate support through routine cleaning and maintenance as well as re-sealing. With that in mind, below are the maintenance efforts worth keeping in mind:
• Pressure Cleaning
While cleaning the block paving with high-pressure water jet is very efficient in getting rid of dirt, grime, moss, algae, and lichen as well as lower the development of weeds, it should be an occasional thing because the pressure can undermine the sand bed on with the pavers are laid. The result of this is sunken sections of the paved surface that may also have some of the paving blocks lose. It is because of this that sealing the paving is essential.
• Scrubbing And Mopping
Given that pressure cleaning should be occasional, the other alternative answer to having clean paving is to scrub and mop. The scrubbing should be done lightly and using a mild-bristled floor scrubber to avoid damaging the seal. But it should be limited to only when dealing with stubborn elements before mopping or sweeping the surface while using running water via a hosepipe.
Sealing should only be done on a clean surface that is free from dust, debris, and efflorescence. If there is the issue of efflorescence, then treat the paving using the appropriate remover and rinse it off using clean water. Give it about four weeks to ensure the efflorescence does not re-occur and then you can seal or reseal the paving. Do the same when dealing with moss, algae, weeds or lichen.
When resealing, ensure the surface is dry and then scrape out the sand between the paving blocks to about 5 – 10mm in depth as you also check to see if the sand is dry. You can use a sanding brook to remove any remaining sand of the beveled edges of the face of the blocks. Apply the first coat of the recommended paving sealer and give it around two hours before applying the next layer. To ensure the sealer covers the borders, use a 4-inch paint brush.
After cleaning and resealing the block paving, restrict any traffic on the pavement for not less than six hours and give it a day before letting vehicles to over the paving to allow the sealer enough time to dry and set in for a robust finish.
