Firstly, leaving it to the spring shouldn't cause any calamitous problems. That being said, I've never left stones down over a winter with absolutely nothing between them and I would imagine that, if you try this, you'll have to reposition some stones come springtime - depending on their heft.14yee wrote: ↑I am doing my patio (200 sq ft) rather late in the season when weather is cold. I am looking for a low maintenance, longer lasting solution. My friends recommend me to use polymeric sand.
The contractor charges me $150 extra ($100 being material & $50 being labor since he has to come back at a later date).
Weather does get really wet and I worry that my contractor won't be able to apply the polymeric sand as it has to be applied when the interlock is completely dried. What is going to happen if I leave my patio unseal for the winter? Would it still be effective if I apply the seal in spring? Should I simply do the regular sand and the effect would more or less be the same?
Secondly, I really wouldn't worry about this issue for a patio that size - it can be covered by a weatherproof tarp if you're really that concerned. If you're insistent on doing it now and your patio is mostly in the shade these days, it will be difficult to get your patio dry enough for a properly-applied polymeric treatment, IMO.
