H-SEAL Concrete COUNTERTOP/WORKTOP Sealer | Food Safe/Grade | High Temp | Matte Finish | Waterproof | UV Resistant (1 Liter)

Easy and fast and turned out great. Applied 4 coats in a about 3 hours. No Mixing necessary with this product Nice flat finish. Buy the recommended roller kit!

A small amount goes a long way. I put five coats over concrete paint on my kitchen counters. Water just rolls off. No chips or stains two months in. I still have over half the container full.

This sealer worked perfectly. You will not be disappointed. There’s nothing that smells. The application was very easy. I have no doubt that I won’t have to use this for years to come.

Calling this product a sealant is misleading; it does very little to seal concrete. In the time since I’ve applied it, simple tomato juice and light oils have stained our countertops in very short times. All this product does is bead water. Additionally, the company lists fluorocarbons as a main constituent in this product (though they’re extremely opaque as to well else is in it). Fluorocarbons are rarely “food safe” as this company claims. Many are bioaccumulative and chronically toxic in humans. Despite my inquiries, the company refused to answer as to what fluorocarbons are used in the product. Highly recommend against this product.

I spent a considerable amount of time reviewing concrete countertop sealers and came up with this or Cheng's. I went with this one based on its ability to withstand heat. I sanded my countertops down to 1000 grit then applied this with a 4" high density foam roller. The instructions say 2-3 coats, but I applied closer to 8-10 coats. The concrete continued to absorb coat after coat. Only until I hit about coat #7 did it appear the concrete was not readily absorbing the liquid and that it was drying in an even manner on the countertop. I did another coat or 2, then did the water test suggested in the Cheng's video to ensure complete absorption of the sealer. I hope this helps someone - 2-3 coats were totally inadequate in my application (I poured my countertops using Rapid-Set mortar mix, not sure if that matters). I was disappointed with the lack of instructions, and there isn't much additional instruction material on their website or youtube. I have been doing concrete for 20 years, although new to concrete countertops, so I have a familiarity with concrete. Not sure of the other reviewers applying this in 30 minutes - it took me about 4 1/2 hours of total application time and dry time to completely seal the countertop. I will revise my review after I have

I'm so happy with the choice I made on this product that I had to get on here and wrote a review. This product worked 100% better than I expected on my cement countertop I made. I'm glad I did not pick the other sealer! Thank you for this awesome product. It's not shiny, just leaves cement actually smooth and withstand cat puke, water etc .. I love this

Tried this for the first time instead of Cheng and it came out really nice. Was really easy to get a consistent finish without any streak marks and only needed 3 coats before it passed the water drop test, and still have some left over for more projects. It seems like less sealer gets absorbed into the surface as it becomes more waterproof with each coat, so it uses less and less sealer with each consecutive coat. I usually try to finish polishing my projects to 1500 grit and this soaked up into the surface really well even at that level of smoothness. The surface is now super hydrophobic and has a really nice natural matte finish! Very happy, thank you.

We had our first BBQ with our new home made concrete top and I thought I’d test how heat resistant it was before firing her up. I heated a frying pan until it was red hot and smoking and place it on the side of the worktop (somewhere not visible) held it there for about 45 seconds and didn’t get any burn marks, peeling or discolouration. Very impressed! Also, I have tried other sealers on smaller projects and it can be difficult to get a good finish. This sealer only took 30 minutes to apply all the coats needed and the surface came out really nice, with no streak marks. Instructions were clear and simple, and I just followed them and it worked out great. Still got some left over and will definitely buy again for future projects, well worth the money.

This product did not work for me at all. I am looking for a refund. Based on what I read about the quality of the sealer I expected way more. Couldn't be more disappointed.

We used 5 coats on our polished concrete bathroom sink/countertop just to be sure that it would be fully sealed and the surface became extremely water repellent! It was really easy to apply and didn't leave any streak marks at all. After the first coat, it gets progressively more difficult for the sealer to soak up into the concrete and by the third coat, it was pretty much just sitting on top of the surface but we continued with a couple more coats just to be sure. All in all it took 45 minutes to apply, including the wait time. It worked really well. Great product - thank you!

Used this on a second lockdown project now and I’m really happy with the finish and the seal it gives each time. I am finding that I needed to use 4-5 coats rather than the 3 recommended, but I’m getting a lot more square meterage out of it than shown, using a clean rag to soak the surface rather than a roller. Very happy with it and still have some left for future DIY adventures.

It’s cement

Very impressed, I took a smoking hot skillet straight off the bbq and placed it on the back corner of the worktop at first just to be sure that if it did burn the surface it would be a little out of sight. And lo and behold I didn’t get any burn marks. First I left it there for about 5 seconds then checked it, then 30 and checked it, then 15 minutes or so until the meat finished cooking and there were no burn marks at all and still just as waterproof. Also super easy to apply and seems to dry nice and quickly in these hot weather conditions so I could put the next coat on straight after the previous and got the job done in approx 30 minutes.
