Hope it holds up for you through freezing and thawing cycles.
Permeability may be good in some applications, not in others.

Not sure if you're referring to the jointing mortar or the polyurethane surface. In the former case, all is well after the first winter just passed. In the latter case, there was some pooling of water at one end during a heavy rain but the rest was OK.

@@peterbloch5590 did you fill in where it was pooling with another layer of mortar mix to stop the pooling?

I’m contemplating on doing this to 4 year old field stone patio for a client. I’m confident that it’s probably settled to where it needs to be. But I’m nervous of thaw and freeze. Do you recommend an alternative. Polymeric won’t work as the gaps in stone are about 4-6 inches in some places

I used rompox in the spring of 2023. It did not hold up in the winter. I will repair with concrete.

You must have some money pal how much did that set you back way above my pay grade that’s for sure nice job all the same

Usually your don't dip the brush into the can of poly, put a little in a cup, helps prevent trash and dust from getting in the van. Mortar removed by sweeping? That is not good. Perhaps the product is less than ideal for this application.

$100 to buy a bucket of premixed flag grout that will only do 5 minutes of grouting. You’re better off buying the bags and premixing yourself (1 part type S, 3 or 4 parts sand)

Polyurethane doesn’t sound like a good idea at all

That's a lot of plastic for a bag of mortar. Different colors? That's not good. Your storage technique sounds problematic. Hope that stuff was made by windmills.
