H-SEAL CONCRETE COUNTERTOP/WORKTOP SEALER | FOOD SAFE | HIGH TEMP | MATT FINISH | WATERPROOF | UV RESISTANT (1 Litre)

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.

Worked really well, I used 5 coats just to be sure and now water beads up on the surface really well, it’s like super hydrophobic now and has a very nice natural effect. Was easy to apply and doesn’t leave any streaks, just soaks right in. I’m still going to apply wax on kitchen area just as a second layer of protection against oil as I’ve read it’s still good to maintain a wax layer for this. Overall really pleased!

Very disappointed in the quality of this product given such high reviews. Maybe I had a dud but despite the most meticulous attempts to prevent streaks from application when each coat dried there were white deposits which have never gone. I will be trying to contact H Seal for a replacement but now I’m going to have to re-sand and start again!

Nos 1.

Finally found a non-toxic sealer that doesn’t leave streak marks and gives a natural finish! Worth the money and goes a long way. We used this for our bathroom countertop and still have enough to re-coat in the future. Going to give this a go on marble too as we’d like to find a durable sealer to coat natural marble in our the bathroom.

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.

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.
