How to Clean and Maintain Block Paving
Block paving can greatly enhance your outdoor space, but keeping it in good condition takes some maintenance. The best cleaning method depends on the type of stain or debris present. Here’s a concise guide to cleaning and maintaining your block-paved driveway or patio.
Maintenance Tips
Prevention is key. After laying your paving, fill the joints with kiln-dried sand to prevent shifting and water damage. Regular upkeep includes sweeping with a medium-stiff broom, using weed killer, and applying outdoor brick cleaner.
Quick maintenance tips:
Use a medium-stiff broom and paving detergent.
Apply a strong weed killer between joints.
If using a power washer, set it to low pressure and hold at a 30° angle.
Always rinse off cleaning agents to prevent discoloration.
Refill joints with kiln-dried sand after washing.
Apply a sealant for added protection, especially in high-traffic areas.
Preparation Steps
Before cleaning:
Clear debris: Remove loose dirt and litter.
Remove weeds: Pull out weeds by the roots and apply a weed deterrent like No Gow Block Paving Sand.
Check for damage: Look for loose or uneven blocks and repair as needed.
Cleaning Methods
1. Pressure Washing:
A popular method that uses high-pressure water to remove dirt. Keep the washer at a 45° angle and use the lowest setting to protect the sand between blocks. Overuse can damage the surface, so follow instructions carefully—or consider hiring a professional.
2. Basic Cleaning:
If you don’t have a pressure washer, soap, water, and a broom can still do the trick. Sweep the soapy water across the surface and rinse thoroughly.
3. Steam Cleaning:
Effective for deep cleaning and removing oil or tyre marks. Though time-consuming and equipment-heavy, it's a great option for stubborn stains. Many prefer hiring a steam cleaning service or renting a machine.
4. Block Paving Cleaners:
These specialized products tackle moss, mildew, and algae. Always follow safety guidelines and wear protective gear when using chemical cleaners. Clean the area beforehand for best results.
Removing Oil Stains
Oil stains are tricky. While steam cleaning works well, another method is scrubbing with a grease-fighting cleaner and a stiff brush. You may need to repeat the process several times for full removal.
With consistent care and the right tools, you can keep your block paving looking fresh and long-lasting. Whether it’s a patio, path, or driveway, regular cleaning can make a big difference in your outdoor space’s appearance and durability.
