Are sealers really necessary?
Absolutely. Marble is a porous material, which means that any liquids which spill onto the surface tend to leech into the body of the marble. This can negatively affect how your marble will look over time. A sealer, or an impregnator as it is also known, can make sure that any materials remain on the surface of the marble, until you clean it off, of course. This is the best way to make sure that your marble retains its original look for as long as possible. Talk to your local outlet about which products to use and how long to leave them before sealing your marble again. Always read the labels of the products you buy, take safety precautions where necessary, and follow instructions carefully.
