HELP !! SEALING A FLAGSTONE PATIO

by chris B

When we moved into our house, we put in a flagstone patio ourselves. The booklet from the wholesale supply where we bought the stone and materials said to finish off the patio with a final layer of slag sand, sweeping away whatever didn't fill in the spaces between stones.

Over the past 6-7 years, we seldom used our patio because the slag makes it impossible to go barefoot, and
it tracks into the house!!! The climate here in MI gets
cold and we are afraid to do anything really permanent,
like mortar, in case it crumbles. Would Permalock sand be a good idea?? or would sealing by itself work??
WE ARE DESPERATE!!!
Thanks for your expertise.

Not familiar with permloc

Dear Chris,

My dad is out of town, so I'll try to answer your question.

Sealing won't solve your problem. The sand will still be tracked into your house.

By filling your joints with mortar, you'll just get cracking over time. If you don't mind doing that every year or so, then that could solve your problem, but that's a lot of work.

I'm not familiar with Permaloc. I looked them up online and I think it would be best if you called them and got their opinion. They'll know if their product will work for you.

I hope that helps you out some.

Great luck!

David
