Help Finishing Flagstone Patio

    I built a flagstone patio (approx 15 x 20). It is built on a sand base. I'm planning to put patio furniture on it. I'm trying to decide what to use to fill the cracks. Most of them are 1-3". I'm not sure if I want sand because it is close to the pool.

    Questions: If I use Sand will hit harden enough not to wash away? Or, should I use some kind of concrete or mortar mix? Should I put it down dry or wet?

    Thanks for any advise.

    If you want to use sand, do a google search for "polymeric sand"? Once you sweep it into the joints and spray it with water it hardens. I'm not sure if it can be used on big gaps though.
    Maybe start a thread in the hardscaping forum here on Lawnsite.

    Mortar mix would be the best, mix it up and put it in a bag...I know they sell these bags at HD...it's like a icing bag and fill those cracks up...its almost like grouting tile.....good luck...

    never mortar joints over a sand or dust base

    only mortar joints over a concrete base

    sand/dust base is flexible, mortar is not

    Well said, How about puting a loam mix in the cracks and adding some stepable herbs and such...

    I was thinking about using stepables around the outside but I'm not sure about what to do towards the middle. Both the table and chairs have solid pedestals so nothing would grow under them and the chairs will probably get moved.

    You guys beat me to it on the stepables. I was just picking up some plants for my house and saw the stepables there. They are so cool. I just wish I had a place to put some. I'll be thinking of ways until I find some. :)

    I just looked and there is a website for them. http://www.stepables.com Do an advanced search and you can select you need plants for shade or part shade and they will give you suggestions (many criteria to choose from). I think you might find something that will work and look very cool between your flagstones.

    Good luck and post pics. I'd love to see it now and after you put some stepables in.
