Today we had a break in the weather and I applied the poly sand to the paved areas.
Matt, you were right in regards to using compaction to insure thorough penetration of the sand and I guess that's where Scott's concern was coming from. I used a hand tamper - since the area is relatively small - with a hard foam pad (similar to an exercise Pad) as buffer. I tamped and swept three times followed by a thorough sweep and used a blower at a low speed to remove the remaining haze. I finally misted the surface (very fine spray) three times at 8-10 min. intervals. I think it turned out OK.
I have a question though regarding curing times. I am aware that the time required for curing is dependant on temperature and humidity. What is the usual curing time of this stuff, and at this time of year where the temp. here is 45-50 F. how long should one expect to wait for it to set.
And finally, these bags contain a certain amount of sand and polymers. When using a broom to sweep this stuff, there is no way to distribute the same ratio of sand and polymer to all the areas of the job equally. So it is safe to say that some areas will have the right amount of polymer and set properly whereas other areas will have little or no polymers and not set as intended.
What do you think?
