Whats the difference between a sealer and an impregnator?
A sealer is a topical application that adds a coating to the surface of the tile. This is normally done to protect against water, oil, or other contaminants. An Impregnator is designed to penetrate below the surface and acts like a repellent. Again, it is suggested that you speak with a tile care professional or installer as to what appilcation makes the most sense. Generally, topical sealers aren’t recommended in exterior applications, becuase they can trap moisture within the stone which may lead to problems during freeze/thaw cycles. In some resined stone products, impregnators can cause dicoloration or fading. As a general rule, always ask the stone professionals if the stone needs to be treated in the first place?
