having finished jet washing and re-sanding of my block paved drive,I have come to the tricky matter of what to do next. to seal or not to seal? - that is the question! I'm completely stuck about 1) what to use - so few products out there and even fewer places to get them from. 2) do the sealers actually work - maintinance free drive for a few years etc. 3) are they cost effective - £100 or so for 1 coat of a medium sized drive. 2 coats are recommended so double that. 4) can you still clean the blocks- brushing etc, or does that erode the sealer I'll be most interested in hearing other peoples stories, if anyone has any. Most people tend to get their drives sealed by the people who fit them. Unlike mine which was there when we moved. As usual, any comments will be greatly appreciated.
