How To Clean and Seal Granite and Travertine

by Roger
(USA)

QUESTION:

Antiqued golden flame granite (tan color) and semi-polished rustic (brown color) travertine were installed as countertops. Both were sealed with a silicon based impregnator.

How should I clean the countertops and would it be okay to add more sealant? Would I have to use a silicon based impregnator?

Also, I've not heard a complete explanation of what "antiqued" granite really means, but I liked the look and feel.

Thank you

ANSWER:

For daily/weekly cleaning you can use hot water (soap will build up on the surface) and/or a granite and marble spray cleaner like STONE PLUS Cleaner.

Sealing again may be necessary since neither surface is polished (polishing makes stone less absorbent). But you don't have to guess about it. You can do a simple test with water that will tell you if your countertops are still absorbent.

Perform this test every year... really you'll notice just from general use... to determine when or if you need to seal.

When it's time to seal I'd recommend using SenGuard or Stone Sentry Sealers.

An antiqued surface is just one of many finish styles like polished, honed, brushed, tumbled.

Usually it's done by water with an added abrasive to give it an old "rustic" look. It's done much more often on travertine and marble because the composition of these stones responds more effectively to the treatment.

Good Luck,
Ryan

How to remove sealer brush marks on travertine?
by: Judy

Can you please advise me what to do about a filled, honed travertine floor that was sealed with Stone Defender Color Enhancer and Sealer. Instructions said to apply with a natural bristle brush which we did but you can see all the brush marks on the tile now that the sealer has dried. so, how can we get this coat of sealer off now & what should we re-apply? Thanks, Judy

ANSWER: If I understand correctly you let the sealer dry on the travertine. If so, there's your problem. You are supposed to wipe all excess sealer from the surface before it dries or you get problems.

If a large area, it may be best just to have it re-honed. Or you can try to strip it with acetone or methylene chloride.

I'd have a pro come take a look before you do anything though.

After you solve the problem you can re-apply an enhancer or sealer. An enhancer makes the stone look "wet" or darker. Apply the enhancer first. You may be able to apply just an enhancer if it is also a sealer.

I recommend SCP-Enhance & Seal.

Good Luck,
Ryan

Using Two Different Sealers
by: Ryan

Sealers can be either water-based or solvent-based.

You can apply a water-based over a solvent-based, but not vise versa.

Also, sealer resins can be of different type and quality.

You noted that your sealer was a silicone sealer. True... silicone sealers are not the best anymore.

Mixing sealers can be a problem because you just never know if they will work together and/or create a crummy look on the countertop.

Sometimes sealers in the same family and brand can be chemically incompatible. That's why the recommendation is to just go with the same sealer.

I'd test on a sample left over tile. Apply some of the original sealer and then a coat of whatever sealer you want. See what happens.

I'm betting your sealer was solvent-based so you can try a water-based sealer.

I'd recommend STONE SENTRY Sealer for a water-based sealer.

Followup Question
by: Roger

Concerning the type and brand of the sealer, would it be ok if I do use a different product to seal the slate, granite, and travertine? My concern is that a lesser quality of sealer might have been used for the installation. Thanks
