sealing a driveway
We recently moved into our first single family home and some guy knocked on our door and offered to fill all cracks reseal the driveway (not sure of the dimensions but about 2 cars long and 2 cars wide) for $150. I researched the matter online and it said to beware of people who supposedly reseal but actually only coat it with oil.
So we bought some latex-ite (the 10-year kind with sand in it) and a squeegee and applied it ourselves after cleaning the driveway, letting it dry and filling the cracks (and letting those cure). Except we ran out and by the time we went back to the store, they only had the kind without sand available, so half of our driveway is sealed with the other kind (color is a little different but we don't care).
-does 10-year latex-ite really last ten years or realistically how long? (we live in VA, so relatively mild but humid climate)
-it's too late for this time around but which is best to use, the one with sand or the one without?
-can you reseal a driveway indefinitely or is there a point where you have to repave and how do you know?
