Just before you sand, go over the areas you have previously cleaned to ensure that no weeds have grown back or that any dirt has been produced.
Before you start, make sure you are wearing protective gloves to prevent any chemicals or irritable plants reacting badly with your skin. Also have a weed disposal bag ready, as cleaning whilst you go will avoid any excessive clean up after.
4. Sealing the gaps
Now that you know how to seal block paving to stop weeds growing through, deciding on your chosen sealer that comes with the desired finish requires some careful consideration.
Whilst we have an FAQ section and a helpful expert guide on our website, we thought it would be a good idea to cover some of the most important pointers for professional patio sealing in the quick responses below.
1: Weed removal
Depending how aggressive your weeds are, choose a weed killer that is right for you. When it comes to these products you really get what you pay for.
That’s right. A flat-topped screwdriver works great to pop pesky weeds out by the roots. If you just grab a weed by the stem, you might get the top part of the weed, but the roots will remain. That weed will grow back faster than you can say “Roundup.”
You can choose to fill the cracks between pavers with a polymer sand. This filler, once wet with a hose, turns hard, almost like mortar. It will make it tougher for weeds to take root.
Step 2: Reach For The Roundup
This spray-on weed killer kills existing weeds and keeps new ones from sprouting for up to a year. It’s a great way to keep weeds from growing between pavers.
Step 4: Fill and Seal
The best-looking patios begin with expert installation.
