Concrete Sealant For Driveways

[stgrhe]

I am thinking of putting sand washed concrete on the driveway for my new house but most of the applications I have seen so far seem to look rather ugly after a few years. Whether that is due to non-use of a good sealant or not I don't know.

Since the concrete surface is rather porous I believe the naked concrete surfaces should be sealed with a proper sealant, and basically I am looking for a product that make the driveway look good for a very long time without the need for maintenance.

My first question: Does anyone have any good experience from using concrete and masonry sealants here in Thailand?

My second question: Is the BASF MASTERSEAL available here in Thailand and has anyone had any experience using this product.
