SelfClean and Shield can be used on all paver types just as long as your pavers are not currently sealed.  Most sealers only last 6 to 18 months. Check with the paver installer or manufacturer of the sealer used and asked for the product shelf life. We recommend 1 coat of SelfClean followed by 1 coat Shield as an application on new unsealed pavers. Old pavers that have been restored more than once may need 2 coats of SelfClean, followed by 1 coat of Shield.
