Q. Can't find this info here or on MBStoneCare.com. How much MB-4 Impregnator/Sealer do I need to buy to seal 100 sq ft of unresined Santa Cecilia Light kitchen countertop. I understand this is an open question since every stone is different and may require up to 3 applications but there needs to be some guidelines. MB-4 is expensive (don't want to order to much) and takes 1 to 2 weeks to order if I don't order enough.

Hi- First off before you order the product test you stone using water in a few areas which you can let sit for 5 or 10 minutes. Then wipe it away and see if it leaves any dark marks. If it does a quart of our product should be enough to get you sealed up.
