Opinions on using Rock Blue on landscaping rocks that surrounds concrete deck around the pool?

I have an underground pool with a concrete deck around it with landscaping rocks around the concrete deck. I'm getting annoyed with the weeds growing through the landscaping rocks and having to keep up on picking them out. Also annoyed when using my blower to clean leaves and stuff around the pool and then also blowing the rocks around.

In looking for solutions I came across "rock glue" you can spray on the landscaping rocks which keeps them from moving and also helps prevent stuff from going through.

Anyone use it or have any opinions?
