GBS Penetrating Concrete Sealer is designed to prevent moisture penetrating indoors or outdoors on concrete surfaces such as floors or wall. It can be used on shower pans. However, please note if you plan on using ceramic or porcelain tile over the top of the shower pan, you can only use a mastic and not thinset as it will not bond once the concrete is sealed.If you do not plan on using tile over the top, this product will not change the look or feel of the concrete at all. If you want a wet look, you'll need to use a solvent-based sealer and we do not sell toxic products like that.
