I have used other sealers from Custom but this one truely is superior to their standard sealer. It penetraded and was absorbed very well and evenly. This was the first time I tryed this particular sealer from Custom and I am pleased with it. It is pricey, however when compared to their standard sealer I found that you truely get what you pay for.
The biggest attraction this product had for me was that it was not solvent based. I applied it per directions with a small brush. It does take some time and as I was doing shower walls and floor plus bathroom floor. I worked in sections and went back and wiped off excess before the maximum time was up. After it was applied and allowed to cure I spot check the grout lines for water resistance and found it had worked as promised. Time will tell as far as how long it holds up but I believe I got the best product for the job.
Luckily I forgot to write a summary right away so I didn't give it the same 5-stars as others have... At first glance this seems like a solid product, but as the week ended I noticed the sheen fade away as fast as it showed up and trying to mop it with just warm water since there is very little product knowledge out there, and I feel I wasted my money now.
I applied this to both bathrooms within the last two weeks. It was easy to apply and seems to be an excellent sealer. Once applied water pools on the tile and does not absorb into it. It is a little early to tell how durable it is, but the directions says it should last 15 years. A bit pricey but if it lasts that long the price is worth it.
I read the specs, instructions, and viewed the manufacturer's video but none answered my questions before I cracked open this $30 bottle. I will call Home Depot again after I write this but so far nobody seems to know much about this product and it is a Sunday so the manufacturer is unavailable. I suggest a go-slow approach as Custom Building Products is not a company that provides much product information other than marketing material. I do not recommend this product on the basis of not enough product information.
We won't know how well this sealer lasts for a few years, or after we spill something. Our bathroom marble looks great after using it, as it enhanced the details in the mable. Our installer said it was easy to use, and 24oz covered all the marble in our bathroom. All of the reviews and information I read before purchasing say that it is one of the best sealers available, and it will last better than most, at up to 15 years... Maybe beyond! I loved being able to order online & pick up in the store, where it was waiting for us at the front desk.
Pros: Durable, Easy to Use, High Quality, Looks Great
