Concrete Driveway Sealer Plus Penetrating Concrete Densifier (Clear Natural Finish) Commercial Grade Outdoor Indoor Waterproof Sealant Protects Pavers Sidewalks Pools (1 Gallon) H2100

I used this on sandstone flagstones and it worked great with one application. It went on very easily. I put the liquid in a pump sprayer, no need to dilute it, sprayed it on the flagstone and it was dry in an hour. I sprayed water on it and voila, the water beads as you can see in the picture. Sandstone is rather permeable and I'm pleased to see how well this works. It dries clear, so you can't see any residue. I also didn't have to worry too much about overspray, as it's very forgiving with minor puddling.

The media could not be loaded. I bought this a while back for our first tiling project because as novices we needed something easy to use. We added one coat using a roller and let it dry for about two hours then to be safe added a second coat. We didn’t need this to be 100% waterproof but needed something that would keep the grout from sticking to the tumbled travertine too strongly and ruining the look of it. After two coats, the sealer seemed to work great (as seen in the video) we got a nice bead of water when we tested it and the tile looked exactly the same. There was no residual whitish haze that I’ve read can happen with other dealers.We sealed a small bathroom (less than 100 sq ft) twice and have almost the entire bottle leftover. We may use it to re-seal outdoor stamped concrete that’s lost its old seal. I’m eager to try this in a sprayer for easier use. It definitely seems like a great consistency for a sprayer.

Okay, if you knew me, you would know that I hate admitting that I'm wrong. My first review said "It does not work." But after the rains, I realized it works great. The water just beaded up on my tile patio table, just the way I wanted it.The instructions say that more than one coat could possibly darken what you are coating, but I found that not the case. I put on three coats thinking the product was too thin and watery, not realizing that it's actually doing it's job.The only drawback is that it doesn't actually put a shine on the table, which I was hoping for. But waterproof is good enough!

I looked for ages for something that would give my outdoor travertine marble tables a smooth sheen... apparently the answer was that it needed to be cut/prepared differently and no top-coat is going to do that for me. So I bought this. Honestly I have no idea if it worked or what it's doing for me... I pressure-washed the tables clean, applied this after they'd dried for a day, and they seemed to get dirty/soiled at the same rate as before. Maybe not? Maybe the grime came off easier when I pressure-washed it earlier this summer again? It felt the same, but who knows. Enough people have left five-star reviews on this that I suspect I'm the one who doesn't get it. Also, bottle arrived leaking and much of the label/instructions had turned to pulp--I looked them up online so am pretty sure I got it right, but it was a big mess to clean up.

I love my flowers, and have them in beds and containers, but watering all the plants I have in containers every day due to moisture loss is a pain, so I applied a coat inside and out to some, and only outside to others – and it works! Holds moisture so much better and I water far less. I used a paint brush, and did a rather sloppy-fast job, too. No shine, no change in color on painted plaster, terra cotta, or concrete.While applying it, I spilled a bit on the concrete walkway. It rained that evening and the spill area remained white, with only water on the surface, whereas the rest of the walk was dark with water. It later dried to all the same color again, of course. So we power washed the filthy walkway and applied this sealer… it stays white during rains now. Amazing!Love the fact that brushes and spray containers are washable with soap and water after using this.

H2Seal H2100 saved my sanity, my pool tiles and grout! Efflorscene the enemy! I have tried too many products, spent hours cleaning only to have the "enemy" return until I discovered Serveon Sealants. Research on the Company confirmed this product would maintain seal even in swim pool environment. Days of succes now a into a month ... the enemy has not returned! H2100 is easy to apply and will maintain that seal. I highly recommend: Read the Directions, Follow the Directions exactly so you can enjoy the same success. Tip to clean: 50/50 mix of water and Muriatic Acid or higher Acid as needed. (Before pic w white in grout on left then clear grey grout in After on right.)

Its like waking on ice when it rains or snows .

Wonderful product to use
