Sealer for Unilock block walkway?
I had a wide new walkway and patio installed in July. I have heard that there are sealers that might bring out the color more, like the way it looks when it is wet. My house is dark brick, and though pretty, the "matching" blocks look much paler. I know sealer on my stone tile in the house made a huge difference in color: made it look richer.
Down the road, are there any negative consequences to using a sealer?
Any brand I should look for? Thanks!
