Do you recommend covering all materials and surfaces that are not being sealed with SEAL-ONCE products?

Yes, we recommend covering all surrounding materials and surfaces, as well as wiping down all areas impacted by over spray while still wet. While all SEAL-ONCE® products are eco-friendly and will not harm the surrounding landscaping, it is advised that you cover any adjacent walls or materials that are not recommended for coating with SEAL-ONCE, especially if you are using one of our semi-transparent tints.
