hi guys, i have just completed my drive with concrete blocks
and am quite pleased with the result. the colour of the blocks
are HEATHER which look well when they are wet. however when they are dry they are rather dull looking. is there a sealer i can buy to keep the colour and prevent algae growth.
i would be grateful for any recommendations.

There are dozens of sealants on the market, many of which are listed here. I'm not sure which ones Tobermore (manufacturers of the Heather Tegula blocks) recommend, but I think it's Resiblock. JointFix from Instarmac is good, as is CoverGard from Nufins.
