Best polymeric sand for pavers

Hi all,

Had a beautiful patio and walkway installed about three years ago. Pavers were Cambridge, polymeric sand was Alliance/Gator. Unfortunately the polymeric sand never set well in the bigger joints, always seemed rubbery, and has now washed away quite a bit from those locations. This was after an initial washout within a couple of weeks and the contractor re-applying the sand.

I went to the supplier of the products who had indicated Alliance improved the Gator products within the last year or so. Not sure I want to go back to them considering the issues I've seen. Planning to just pressure wash and "touch up" the bigger joints rather than re-do the whole patio since the rest of the sand is in good shape.

Can you recommend a suitable, solid polymeric sand so I can re-do these joints? Thanks.

Also - I have one capstone that has loosened and will probably pull up. Can you please also recommend best block adhesive to reinstall it?

Thanks!

Have pretty much always used Gator sand, honestly it's a pretty basic product sand and binding agent, the application/installation is more critical than the product.

Any name brand block adhesive will work, just dont use a construction adhesive!

Polymeric is not good for big gaps. But, I've found it holds up pretty well if installed properly. I've used a couple different brands of Polymeric and they have all performed about the same. The installation/application is VERY important. The binders and sand particles can separate apart during installation which can create very weak areas. Also, using a vibratory plate compactor really helps a lot to get the sand to densely settle down into the joints before watering.
