Why are There WHITE SPOTS ON MY PAVERS + How to Clean Them 

I enjoy your channel. Its good to see someone who knows what there talking about and willing to help smaller guys learn and make there bussiness better, I have a small company thats been in business about 8 years and this kind of info would have been awesome to have when i was first getting started instead I had to learn the hard way a few times that first year. Id always use acrylic sealers so when i was inexperienced i didnt understand the pavers must be bone dry when you start so you dont trap moisture between the sealer and the paver. I also learned that you can overapply the sealer and you end up layering the sealer over itself which doesnt allow the original coat to dry properly and a secound pass over top will trap the moisture from the orginal coat and give you the same effect. At least with acrylic sealer, water based sealer thats never a issue but it just doesnt have the protection as acrylic plus water based doesnt look nearly as good in my opinion and the customers in my area tend to agree.

I feel like efflorescence is less common now that most guys are switching to open graded base.
