Question DetailsAsked on 11/1/2013

How often should granite be sealed? Can I purchase a long lasting sealant?

One fabricator told me all granite comes from the quarry with a resin so it is not necessary to re-seal one's granite.
Another fabricator told me I could pay $150 for a sealant that will last for 10 years. Another told me $350 for a 15 year sealant. My fabricator told me to re-seal my granite every 6 months. Who is telling the truth
Is there a sealer I can purchase that is economical and will last a long time?

omg some body is trying to rip you off. stone work is my specialty. the truth is granite is porous, therefore sealing is needed. some stone are more porous than others and require very little sealing. you can go to your local home depot or lowes and go to the tile section and pick you up a bottle of sealer for around 50-60 bucks. its very simple think of stone like a sponge, if you pour water on the surface and notice the area starts to darken, than it needs to be sealed, if it just puddles up than there's no need to seal it. on the back of most bottles of sealers are step by step directions. follow those and check your stone in a few months by pouring water on the surface, give it a few minutes and see what it does. there are sealers out there that are better than others, I get mine from a granite distributing company "triton stone" its a simple wipe on wipe off application mostly. the ones at lowes work great as well, any further questions 225-603-7563

Not all granite comes treated - some are shipped "bare" because the fabricator is going to do special edging or such on it. I cannot imagine any sealant lasting 10-15 years - 6 months is sort of short too, but I bet you fabricator said that because he (rightly) does not want complaints about staining - and many sealer manufacturers recommned every 6 months. Remember, it only takes one place where it is worn off for a stain to occur.

Wetting the entire surface to check if ANY areas start darkening is your best check - but if any do, it means you are PAST time to seal, because oil and foor stains would permanently stain the same way, so you should really do it on a regular schedule. I would recommend not more than 3 years between sealing - using a good brand name sealer like DuPont BulletProof Stone Sealer or DowCorning 700 series (exact number depends on whether previously sealed or not and if exposing to boiling temperatures, etc) Silicone Stone Sealers.
