Sealing granite countertop

Need to seal two granite slab countertops. Is penetrating grout sealer the same thing as granite sealer or do I need to buy a product that specifically states "granite sealer"? Thanks.

If you don't get any knowledgeable responses in here, nor by phoning the companies that supply and install granite counter tops, I'd open your yellow pages to "Janitorial Equipment & Supplies" and phone around to find out who sells S. C. Johnson Wax products.

Phone that place and ask for the name and phone number of the local S. C. Johnson Wax sales rep. Explain the situation to him and see what he recommends to protect a granite counter top from stains rather than to serve as a finish over a granite floor.

I expect that any finish the have for granite flooring will dry to a very hard film, which means that it would be a crosslinking acrylic that crosslinks very heavily to form a very hard and strong (and therefore also very impermeable) film. That impermeability would also help protect the granite from stains.

Keeping this very simple...there are two types of sealer for stone: impregnating and topical.

One penetrates into the stone and acts like a pore-filler, these are called "impregnators". The other (the 'topical') sits on the surface and is like a floor wax. You can buff it to shine, and even remove it, if you want...

I prefer the impregnators, as they are really designed for stone. Your $5k kitchen countertop isn't a place to experiment with $20 floor waxes

PS: I like that site given by buletbob. Plus it endorses our mentor and recently-departed stone guru, Maurizio Bertoli's products.

Here's what I use. It has a strong smell for a day or two though.
