HOME: How do I seal seams between bricks on a patio without using sand?
I have a patio that's made of bricks with fine sand filling the gaps. This is turning out to be a maintenance hassle. Every time the kid or dog gets mud or crud on the patio I hose it off and manage to blow more and more sand out of the cracks.
Is there a way to seal the seams between the bricks or use something more sticky than sand... like a fine grout? I like the look just fine, but it appears that I'm going to be spending a lot more time than I desire on maintenance of my patio.
What you are looking for is a joint sand stabilizing sealer. That should prevent washout as well as weed growth in the joints.
You could mix up a fine sand & cement mixture brush that into the gaps then water the patio to turn that into mortar in place.
You'd need to make sure the patio was clean first, and don't use too much water.
Though this would be a fairly permanent solution.
Fill them with sand then carefully add pure cement to the top of the crack and lightly spray with a mist until the cement washes down into the sand and then no more. Let it set a day.
You can try the polymeric sand. It is sand mixed with some binding agent. You fill the gaps with this sand. Use a broom to remove excess from the brick surface. Sprinkle some water at the joints and the chemical reaction starts. My experience with a specific product was so so. May be I did not do it right. But polymeric sand claims to be for the purpose, you are looking.
