We love the look of white marble countertops, but what about the age-old question of marble surface protection? It's a discussion that generally ends in, "Get a marble sample and test it out". While few of us have actually done this, Greg over at The Petch House conducted extensive and brutal marble tests and documented the process for us all to see...
The Petch House's test started with a sample from the countertop slab. Sealant was applied to one half and the other was left as-is for a comparison of sealed and unsealed marble. Then the sample was covered in all kinds of acidic foodstuff and beat up with a dinner knife.
Testing continues here, after the sample has a chance to rest a bit, and final results and observations are here. Thanks to Greg at The Petch House for putting this sample to the test and sharing it all with us.
