When I stopped at a local garden center, I asked them and they showed me to the product. Maybe I'm the only one who has never heard of it, but you put it between the stones, water it and let it harden into a concrete filler.
I offered James the job and he cleaned the patio well today. He had to dig out and blow the sand and dirt that was between the stones. Within the next few days we will put in the "super special patio sand" and then it can't be walked on for 24 hours which will be challenging!
See how all the weeds grew in the cracks?
They are gone today -
While James did that, JD worked on the never-ending wiring job in the garage and the kids and I planted 5 of the 7 garden beds. We pulled out 4 full wagon loads of weeds.
Before I started the garden, I laid three bags of grass seed. While I was waiting on the promised rain, I had to keep running the chickens off of every time I saw them.
