Hello dman,

I'm thinking I saw the Techniseal name on a Unilock bag of poly sand. That doesn't mean they can't change the formula for the bags of sand with the Unilock emblems on them - that kind of thing happens all the time.

My experience with each has been very positive.

Dman,

We installed a flagstone patio this past fall and used Techniseals
HP poly sand and it has the problem of not completely harding. I also noticed some washout. I figured it didn't totally hardin because some of the joints are wider than an inch. I guess I should call techniseal to see whats up.

Yea, you're right, I suppose Techniseal could've come up with a slightly different blend to sell to Unilock - I still maintain that its an inferior blend than their original product though.

And Keith N, you should contact Techniseal and see if they can send a rep out to look at your job, you never know, maybe they'll credit you some product or do a repair. I know Alliance DP just came out with a product for flagstone good for joints up to 4 inches - called Gator Dust or something and comes in gray and brown.
