granite

Two questions. First is about sapphire brown granite. I have a counter done in it and it does not appear to need sealing (bylemon and oil test), but it can get a little dull. What can I do to get a more "wet loo". Second is about a counter I had installed that either has 2 different slabs or different granites! One side is definitely St. Cecilia. It is glassy and smooth and well fabricated. The other half is fissured and gritty and the laid out with the sections going in different directions. I don't know what granite it is. It is simiar to Cecila but the pattern is not diagonal. It has a much lighter background and is more brown than gold. The patten is more spotty looking.The contractor agrees that half of it need to be replaced to get match. We want to keep the unknown half but I am leary because of the gritty feel. can this be resolved by sealing? If a glass of water is left on it, it discolors but then dries out and returns. Sorry so long but I don't know what to do. THANK YOU SO MUCH.

 

Dear Kathy:

The followings are all classified as Sapphire Brown “granite”:

 

          And I could post even more pictures!!...

 

Now, you tell me if I could even try to guess which Sapphire Brown “granite” you have!!... :-)

Having said that, about the “dullness” it's either a stone that doesn't get any shiner than that (which is the most probable cause), or it was not polished properly by the factory (which I highly doubt), or it's a low-grading slab.

No matter what, there's not much that you could possibly do about that, and anybody else for that matter.

 

As for the Santa Cecilia issue, I could post of few different pictures of that one, too!...

 

As for the gritty feeling, it is exclusively a matter of poor grading of the slab and no sealing could ever do the first thing about it, if you consider that sealers for stone are strictly below-the-surface (of the stone) products and that them most important phase of the application of an impregnator (a.k.a. sealer) is the thorough removal of every residue of the product from the surface of the stone. In other words, at the end of the sealing job, the stone surface must be as bare at it was before the beginning of the application. A good sealing job would help solving the problem of the temporary discoloration of the water, though.
