Putting a sealer on will help you so much with maintaining the whole thing better. But be sure to wait for 24 to 48 hours after you install the surface and let it dry out properly. That's going to help you get the best effect with the sealer. If you can't wait longer, just try to go for at least one day to let the surface dry out a little bit. That's going to make the sealer work so much better on the surface, which is vital in the process.
