Staining and/or sealing large concrete driveway?
The driveway at my home is a mismatch of different coloured concrete. It has obviously been enlarged over the years and pieced-up with mortar at various points where the original concrete has cracked. In an attempt to make it more attractive I have been thinking about sealing it or staining it. Which would be the better option?
Alternatively, would I get away with painting it with external, eg masonry, paint?
