Which Granite Sealer To Use?

Marble & Granite Sealer Comparison

Marble & Granite Sealer Comparison

QUESTION:

I was wondering... are there any reviews or studies ranking the performance of the different granite sealers?

I just purchased granite counter-tops (crystal yellow), and I want to seal them. However, there are many different sealers out there.

I have looked at two in particular: MB-4 Impregnator/Sealer for Stone, and Stonetech Bulletproof Stone Sealer. Any other suggestions? Thanks for your help. Sincerely, LJ

ANSWER:


LJ, I understand your confusion. Although sealing granite and marble is a simple task, getting the right answers and deciding how to go about it can give people fits sometimes.

The following granite sealer review and discussion will provide the desired perspective, answers and advice to help you confidently compare, evaluate, and decide which sealer to use.

The chemicals /ingredients have evolved (and are still evolving), so they get better and better, but there are still plenty of low-grade sealers on the market.

An explanation of sealer technology, different types of chemical formulations, how sealers work, how to apply sealers correctly is found in the All About Sealing Granite & Marble e-book. It doesn't break down every brand, but it does thoroughly cover this topic, so consumers can get a detailed understanding about sealers.

A scientific sealer comparison would be great, but that's a tricky task.

A true comparative test would need several years with samples undergoing "normal" use and cleaning, or at least some type of accelerated process that simulates years of use in a short time.

Either way... quite a project and maybe of little use by the time completed as new or improved products hit the market.

Years ago Stonetech was cutting-edge, and I've recommended bulletproof in the past. It's still a decent, but average product similar to others in its class like Miracle 511, Marble Life, Stonecare International, Rock Doctor, Black Diamond, Weiman, Aqua Mix, etc.

MB-4 Stone Sealer is far better... very good product, much more durable and longer-lasting than Stonetech. In fact, it used to be the best on the market until recent technological advances discussed below.


Stone Care Pro Impregnating Sealer is also very good in this class and cheaper than MB for essentially the same performance.

However, today... none of the above would rank as the best. Sealer technology has advanced far beyond how those two sealers work.

Development of high-quality permanent stone sealers has left these behind.

The top product now for sealing granite & marble countertops (and other natural stone or porous surfaces) is the SenGuard DIY Sealer Kit.

SenGuard is currently the best sealer available utilizing the most advanced and durable chemical technology yet invented forming permanent bonds with the stone, which means... only one application necessary... no re-sealing!

Obviously, this is a big step up from "traditional" sealers that require re-application.

SenGuard is also super-easy to apply and comes with instructional DVD and book, etc... everything you need to do the job properly.

We still recommend the Stone Care Pro Impregnating Sealer and MB-4 Sealer. These are by far the best of the "last generation" sealers.

The cost is less than SenGuard up front, so these are good choices if on a tight budget or when sealing a large floor.

However, both will need periodic re-application, so time / effort / cost catches up with you in the end. All considered (total lifetime cost, performance) SenGuard is easily the best value for all countertops and vanities.

Just remember that no sealer will work as well as designed without proper application. It's not a difficult job, but you must completely saturate the stone without letting the sealer dry on top.

Follow the directions carefully and you'll do fine.

First and foremost, be sure to perform the sealer application test to determine if you even need to seal the stone.

If you don't know... and many don't... some stones just don't need sealing and trying to apply one can cause problems with a hazy film.

Now, Crystal Yellow almost certainly will need sealing, but it's always best to test

better sealant

i have had my tops sealed with Granite Shield, this green product came with a lifetime (transferrable) warranty against stains, they had certified technicians come to my home and apply the sealant and now my tops look brand new everyday ...

Re: Better Sealant - Granite Shield
by: Ryan

Granite shield is a very good sealer. Forms permanent bonds requiring only one application just like SenGuard Marble & Granite Sealer, which is the sealer we recommend for a few reasons.

We take issue that granite shield uses misleading language and in some instances flat out lies on their website.

Granite shield is not a "green" product. By having to seal only one time, you save from throwing away bottles of other sealers that require re-application. Good, but hardly qualifies as a "green" product.

From granite shield website:

"You don't have to worry about wiping up spills immediately or have to use coasters or place mats like you have to do with other presealed granite countertops."

--Just not true. You don't have to use coasters or place mats, etc. or worry about spills with "other " sealed countertops either.

"With other well known sealers they are temporary and depending what you use to clean your granite may only last weeks, usually 6 to 12 months at the longest. "

--Flat out false. While it is true that some sealers will require re-sealing this quickly, there are several sealers on the market that will easily last 5 year and up to 10 years on some stones.

"In the long run using Granite Shield it will save you hundreds to thousands of dollars,"

Granite shield is very expensive. It must be applied by a franchised operator and only so many "licenses" are allowed per area, so prices remain high.

While it may save you the trouble of re-sealing, you'd have to re-seal 3 to 10 times (depending on the sealer you use) before granite shield would save you money.

They do provide a lifetime warranty, but is it worth anything?

I'll say the same about GS warranty as Senguard warranty...

You are paying a lot and getting very little. Your risk of staining is minuscule. If you did manage to stain it... stains are rather easy to remove.

You end up paying $100s more for a warranty you'll never use and they know it.

That's why we recommend SenGuard... Same protection... way less expensive.

No warranty, but as I've explained here and in several other posts, I truly believe the warranty is near worthless.

Stains and etching are easily and cheaply handled by the homeowner.

Again, GS is very good. If you choose to use it, you won't be disappointed. I just think you have a much better choice that provides the same permanent bond technology and protection for at least 50% less.

Ryan you're full of it

I think that your opinion of Granite Shield is what is misleading. You are bashing the product without much factual information and your statements are very opinionated.

First, you claim that Granite Shield and SenGuard are similar, yet only GS guarantees their information. Well, I think that makes GS a little more trust worthy. The cost difference you mention? Not true. Granite Shield costs as much as any sealer.

You then go on about how warranties are "useless," especially Granite Shield's. Are you serious? Your reasoning is that "stains are rather easy to remove..." I can tell you do not know what you are talking about because lots of stains become IMPOSSIBLE to remove. I know this from experience. Plus, most of the regular sealants, even SenGuard, can absorb stains even if correctly applied, so I would say the use of coasters and trivets is ABSOLUTELY necessary, unless you have GS that is.. Why? Because, opposite of your statements, Granite Shield guarantees you wont get stains. If you happen to get a stain with SenGuard, a stain that wont come out, SenGuard wont help you, and that would make me want to use a coaster. GS will, however. I would say that's a very useful and reassuring warranty.

I also think GS has the right to call themselves green even if saving bottles is all they are doing. Grocery stores claim to be green by offering tote bags rather than plastic, but you don't see people calling them liars.

I am not "bashing" granite shield. In fact, I stated 2 or 3 times that granite shield is a very good/excellent sealer.

Yes, it is my opinion and that is all I expect anyone to understand. However, we take the consumer's point of view and detail the pros and cons of any stone care issue.

All factors considered Senguard is the top sealer on the market providing a much better value for the consumer, which is why we recommend it over all other sealers... period.

Senguard performs far better than all standard sealers... and it performs as good as Granite Shield, but much easier to apply and far less expensive. You simply can't buy a "better" sealer than Senguard.

Maybe you've had trouble removing a lot of stains and it is true that stains can "become" (key concept) impossible to remove when left for years.

And certain stains are very difficult/impossible to remove. However, such stains constitute a miniscule percentage of all marble and granite stains that occur.

The vast majority of stains are very easy and cheap to remove without any need for professional help (see Removing Granite & Marble Stains e-book).... especially if in the rare event they have occurred on a sealed countertop.

So, in light of this paying for an relatively expensive sealer warranty (far more expensive than the actual cost to remove a stain) isn't a good bargain.

Why pay in advance for a service that 99.5% of customers won't ever need... particularly if (as you state) GS guarantees that you "wont' get stains" at all?

Which I don't think is exactly the case since a few GS licensed applicators have contacted us to discuss our knowledge and experience with Senguard precisely because they had trouble with warranty service (and other issues) from granite shield HQ.

It simply makes more sense to save the money, apply a sealer like Senguard that has the same performance, but without all the muss and fuss and high cost of granite shield.

And agreed... saving bottles from the dump is great... a step in the right direction. My point was only that the GS product itself is not "green". Simply "claiming" to be "green" doesn't make it so.

resealing SensaStone
by: NoPermaSeal

Very informative from both sides - yet I have a question. Seven years ago we put in new granite (New Venetian Gold) which came from the factory impregnated with the SensaGuard (it was SensaStone). I.e. we never sealed it and kept it clean.

After six years, we had an issue with a crack in front of the sink - oxidation jacking. Long story short, after three years of discussion, the manufacturer and the store agreed to replace our stone.

The old stone had developed many pits and pocks and chips around the sink area and was rough to the touch.

Away from the sink area the stone was like new. Obviously, the factory seal wasn't perfect. There was zero - I mean zero staining of any kind.

Now that we have new SensaStone counters, what cleaner and sealer can I use to make my new stone stay looking new even after six years down the road?

==== Countertop Specialty comment:

Sounds to me like the pre-sealed Sensa stone lived up to billing. Sealing only prevents staining and you noted no stains at all... and that is what you'd expect with Sensa. You didn't seal it, but the Sensa granite comes "pre-sealed".

The pitting is a completely different issue. No sealer will keep a stone from pitting. All granites have the potential to pit, but some more than others.

Unfortunately, New Venetian Gold is prone to pitting and chipping. And this will typically happen more around the sink due to all the water and constant impact occurring in this area.

If you get pits again, then just fill them using this repair kit for pitting and chipping in granite, marble, quartz.
