Filling Joints in Patio Pavers

By: Joe Truini

The joints between patio pavers are usually filled with sand, which has a tendency to wash out of the cracks over time. PowerLoc Jointing Sand from Quikrete is a polymer based product that prevents it from washing out or cracking. Simply pour it out and sweep the jointing sand diagonally into the cracks with a push broom. To lock it in place, mist the surface down with water from a sprayer, going over it three times within an hour, and let dry.

    Hi. I just paved my back patio.the gaps if filled with sand may blow away when I power clean as we have lots of leaves and dust. What is the best filler. Thanks.

    Hello. I have moved into a house where they just laid the concrete pavers on dirt, so every time it rains, it’s a mess! Dirt splashes up on everything. There are also some concrete slabs that have wood spacers between with dirt on each side. If I power wash out as much of the dirt as I can, could I then apply this sand? Most of the pavers have only about a fourth of an inch between them. Between the pavers and the concrete is about an inch of dirt. Same with where the pavers connect to the house. It creates so much dirt as it is and drives me crazy! Thank you!

    Is it okay to pressure wash or otherwise clean out the cracks in my patio stone before filling with the polymeric sand as over the years it has filled up with debris, weeds, etc.

    I would like to know how you answered, Tom Jennings, concerning the gaps between his flagstone , I also want to fill gaps between 12 x 12 inch pavers, the sweep in kind just washes out and does not harden. Please help

    I watched your video filling gaps between pavers using jointing sand. Looks great but the gaps between your pavers were very narrow and the gaps between my patio flagstones are very wide and I am wondering if jointing sand would work on wide gaps or if I should use a mortar. Wish I could attach the picture, but right now we have small rocks filling the gaps, which are messy. If I should use mortar can you tell me what to get and how to use it?
