which granites don't need to be sealed?
Comments (11)and if a stone will absorb a sealer, it's a good idea to use it. Absolutely. However, many stones won't absorb it. The pearls for example-- Blue Pearl, Emerald Pearl, etc.-- or the black granites, such as Absolute Black or Black Galaxy-- none of those will absorb a sealer, and as a result end up looking like there's a haze on the surface. Another popular one is Ubatuba. Although there used to be some slabs that would take a sealer, 99.9% of the Ubatuba found today, won't. In the following link, at the top of the page, you'll find two other links-- one, A-L, and the other, M-Z. Both links will take you to a chart of the most popular granites from around the world. On those charts is a column for absorbsion rates. If the rate of your granite is .25% or less, it SHOULD NOT be sealed. If you have a granite that's not on the list, try the "sponge" test. Lay a sopping wet sponge or rag on the countertop. After a couple of minutes, remove it and then wipe up any water sitting on the surface. If the stone under where the sponge or rag was sitting darkened, then your stone needs to be sealed. Otherwise, you're okay to leave it as is.

Comments (4)bill_vincent: Thanks for the response. The granite is called Azul Platinum and yes it does get slightly darker when it gets wet. Luckily, it returns to the regular color after sometime. What would you recommend cleaning the granite with? What do you think about the Simple Green Stone Cleaner product? Bone dry...will 24 hours be long enough? How does one know when granite is bone dry???...See MoreDo I need to seal my granite countertops?
Comments (3)Nothing can really hurt your granite. Some colors MAY show some oil staining if not sealed, but granite is much sturdier than marble, which can easily stain. I've had my granite counters for 13 years. They are a mottled golden brown agains my unstained cherry cabinets. My husband does use some sealer about twice a year and purchases it from Lowes or HomeDepot....See MoreSealing granite countertop
Comments (3)You are right! The fabricator says the granite is sealed. What the installer said apparently referred to follow-up maintenance. Thanks for setting me straight....See MoreMiguel Deleon
