You need to run the vibrator plate after adding the poly sand in order to make sure that it settles properly in the joints, otherwise you can get air pockets that may pop out down the road as the top layer of the sand washes out over time
80 dislikes of people who work on this type of job and now you can do it by your self without paying a lot of money and it’s easy I already done something like this hahahaahaha
I think a lot of people can follow this instructions; but do they have a healthy back? are they patient enough? do they have long enough attention span to measure tamper, level, etc.? 4+ inches of dirt is a lot of dirt, where would I put it? If they have the money to buy pavers+gravel+sand+machine rental, then they probably have the money for hiring someone else to do it🤑. Well I failed the test😌, I can only embark in this project if I make a 4X4 feet patio😁
