I applied "Armor AR350 Solvent Based Acrylic Look Concrete Sealer And Paver Sealer" to the concrete curbing surrounding our flower beds.  I used a 4" wide roller with a 1/2" nap and wore vinyl gloves.  The rose color stood out brightly as it was applied, but as it dried completely it was even more stunning.  It is very easy to apply and clean-up. I did apply two coats.
