Tips on Keeping Your Block Paving Clean and Pristine
Jointing Sand Right After
The joints on your block paving will be porous for the first few weeks following installation. Any water that reaches the joints will combine with the sand and end up flushing the sand out. This is even more true in sloping areas. To avoid this, joints should be topped with jointing sand.
Block Paving General Maintenance
Regularly sweep your paving using a stiff broom, especially at the beginning of Spring. Along with the broom, use a non-bio detergent and a weed killer. Preventing weeds from growing around your block paving prolongs its lifespan because weeds that grow in between the joints would weaken the paving.
When you hose down your driveway and you’re using a power washer, make sure to angle the water at 30 degrees or less. This will spray the water at a diagonal angle, which will then lessen the pressure that is applied directly on the surface. This is to avoid damaging the patio surface because of too much pressure. Also try to only use light to medium pressure.
After cleaning your driveway with detergents, make sure to thoroughly rinse the area. Then rinse out drainage points as well, and make sure to do this thoroughly. Build up of detergents that are left on the surface can end up weakening your pavement. In doing this, be aware of any required resanding or repointing in the pavement.
Treating Algae, Moss And Lichens
Moss, algae and lichens grow naturally but they grow even more in areas that are damp and shaded. If your driveway has these growths, scrape them off then treat with a moss killer and weed killer. Wait for a few days for the products to take effect, and then you can brush them off.
Removing Stains Caused By Cars
For rust stains, you need to wet the area then apply a solution with hydrochloric acid. For oil stains, it is important to treat the area as soon as possible because the longer the stain stays, the harder it will be to remove. Soak up the area then brush it and hose it down.
For paint stains, soak up the area using an absorbent material. Make sure that you don’t wipe the stain around the area because the stain will only spread. Then use a solvent to completely remove the stain. This is easier to do with fresh stains.
If the paint has already dried, try to scrape off as much of it as you can. Then use a paint remover solvent and wash the area thoroughly.
