Is anyone familiar with Pakmix Proline polymeric sand? I found it for $10 for a 50lb bag at Menards which I thought was really cheap compared to the Unilock's poly sand I've used once before.

Yesterday I applied this stuff and I was amazed at how easy it went into the joints and at how little dust there was left on the pavers compared to Unilock's. I was thrilled. I wet it down per instructions. but this morning it's not bonding up and it seems no different than regular sand in the joints. Even worse, ant hills are already popping up.

Unilock's poly sand dried like mortar the one time I used it. This stuff, after 24hours is not bonding at all. Does it need more time? Is it junk? Any help would be appreciated. Thanks.

Ugh. Same brand? We'll see if anyone else has any input... thanks.

All I can tell you is you get what you pay for. You want professional paver products, you can't find them at the big box stores. Menards included. I've heard of a really large brand of sand selling a "polymeric" that did not perform any different than silica or torpedo sand. So I'm thinking you have junk sand. Your best bet may be to power wash it out and start again.

Check with your local paver suppliers to get your hands on real poly sand, and pay the extra $10 per bag.

thanks Stone, I'm thinking it's junk too. I had a really bad experience with Unilock's sand. It was so dusty I never got it off my pavers and it formed a hazey look. I'm afraid to try it again.

I guess I'll power-wash it all out while I have my buddies pressure washer on hand.... argh!

EDIT - I'm really torn on washing it all out... what if I just put a sealer over it? Will the sealer hold down the sand?

If the joints aren't too big, that would work fine.

unilock has a special sealant that also bonds regular sand ask your sales rep for it.
