How do I stop weeds from growing between paving slabs?
Sprinkle baking soda
Baking soda is probably the simplest and safest way to soften up and kill weeds. All you need to do with it is sprinkle it over your patio slabs and then sweep it into the gaps between your slabs. Once you’ve done this, simply pour some water down the gaps too.
What is best to fill the gaps between pavers?
Traditionally gaps between pavers were filled with a mixture of one bag of sand and one-quarter bag of white cement. These two ingredients are mixed in a wheelbarrow and spread on top of the pavers. A broom is usually used to push the mixture in between the pavers.

Does polymeric sand stop weeds?
When the polymers dry and cure, the sand between the joints gets quite hard and it cements the pavers together. Weeds won’t grow between the joints and the sand doesn’t wash away.
Is polymeric sand worth it?
Polymeric sand is the more reliable and durable option for filling in the paver gaps. It outperforms regular sand when a homeowner is looking to lock the paver joints properly and wants a steady and stable path. It also provides a better appearance with its cleaner look and availability in varied colors.
How long does polymeric sand last?
Polymeric sand is the most popular and useful filler used under brick pavers. It is a mixture of fine sand, adhesive and is most widely used in paver joints. Typically, polymeric sand lasts for up to 10 years. But if you use high-quality polymeric sand, it can last for approximately 15 years.
Do you need to seal the sand between the pavers?

Should you seal pavers before polymeric sand?
Traditionally, concrete paver manufacturers have recommended waiting at least 90 days after polymeric sand installation to apply a protective sealant to a paver surface. Nowadays, a 30 day delay is sufficient to allow the evaporation of any remaining natural efflorescence contained in the pavers.
What are the problems with polymeric sand?
Over time, the sand in between paving stones will erode and begin to fade. For the DIY pathway, this means you will need to fix the pathway in as little as 1-2 years, depending on weather changes.

Can polymeric sand ruin pavers?
Improperly installed poly sand can ruin a great paver project. If you want your patio finished for tomorrow’s family picnic, you should rethink your timeline. Because it takes time for sand to set, you’d be better off rescheduling the installation. It’ll be worth the wait to avoid the risk of a potential disaster.
