How do you harden sand between pavers?

As we brought up earlier, regular sand doesn’t harden enough on its own. So, if you need it to set, the best way to do it is by sealing them. You should give it at least 48 hours after applying the sealer. Foot traffic is ok after 3-4 hours.

What if it rains after putting down polymeric sand?

Is polymeric sand permanent?

Can polymeric sand be reapplied?

Unfortunately with polymeric sand replacement, you can’t just uproot any weeds and top it up. Secondly, you will have to wait a day while the surface dries before you can reapply your new sand. Remember polymeric sand and moisture don’t mix until after it’s in the joints!

How do you remove hardened polymeric sand?

Can you use polymeric sand to fill driveway cracks?

Should I wet sand before laying pavers?
