Do I have to seal my clay pavers?

No. In fact, it is strongly recommended not to seal a clay paving brick. The colors will not fade and the surface does not wear down. This is because genuine clay pavers are baked in a kiln at extreme temperatures, fusing the clay particles together in a process called vitrification.

If for some reason, you still must seal your pavers, be sure the sealer you select is a breathable, siloxane based sealer such as Euclid Chemical's Weatherguard. DO NOT USE AN ACRYLIC BASED SEALER!
