BioShield Herbal Oil is a penetrating sealer created for raw, freshly sanded wood and not over previously stained surfaces because those surfaces may contain chemicals may prevent penetration or react poorly with this oil. Sometimes, if the stain is very old and dried out, the oil may penetrate just fine. It's difficult to make a broad statement about how it will perform over any type of wood or stain. Testing is the only way to know for sure. We offer small samples of all our products on our website. We suggest you try it.Another option would be to try our AFM Safecoat Acrylacq which is a clear topical sealer that will provide better abrasion and moisture protection.
