It was very easy to mix and put on with a sprayer now I have to just wait 5 or 6 months. See how it holds up.

Easy to use.
Easy to use. No mixing necessary. Clear instructions. Too recent to have full results to share but early indicators are positive.

Pretty effective
[This review was collected as part of a promotion.] I cleaned and used this on a small section of my paver patio that stays in the shade. It was easy to apply and has so far kept it free of green moss growth. I left the surrounding areas green to show the effectiveness.

Easy to use!
[This review was collected as part of a promotion.] This can be useful for so many areas at my house, I want to use it on everything. I have quit a few areas that get mold growing on them. I started with my stamped concrete porch. I used my garden sprayer and it was very easy to apply. It only takes about an hour to dry so that wasn’t a problem staying off it. It doesn’t leave a sticky film, you hardly even notice it is there. I plan on putting it on my new roof next. I feel a lot better knowing...

Brought my patio back to life.
[This review was collected as part of a promotion.] Really happy with how this turned out. The product was easy to apply with a roller, spread well, and gave the patio a fresh, clean, richer look without making it look overdone. It definitely helped bring out the texture and color of the stamped concrete. Drying and finish were solid. Taking off one star only because coverage/application needs a bit of care to keep everything even, but overall it did the job well and made a noticeable differe...

prevents stains
[This review was collected as part of a promotion.] Great product. Easy to use and works great. Perfect for the floors in our house. Prevents from staining and it’s exactly what I was looking for. Not sticky at all and gentle to touch. The 2 gallon was plenty since you don’t meet a lot to use.

Wipes out dirt and grime quick.
[This review was collected as part of a promotion.] This is amazing stuff little goes a long way. Sure dissolves the dirt and grime on the garage floor. A good stiff brush and a little elbow grease and that yucky stuff came right up.

Easy to Use and Effective
[This review was collected as part of a promotion.] The Seal Once Stay Clean Ready-to-Use Formula was easy to use and had an instant effect. I used it on the paving stones leading to my outdoor shower, which get a lot of use during warmer months. This product was easy to apply and dried fairly quickly. I could definitely see a difference. I’m excited to see if it seems to repel water the next time it rains.

Easy to use ready made formula!
[This review was collected as part of a promotion.] The seal once stay clean ready to use formula was very easy to use. The hardest part was waiting for the weather to be consistently warm enough (between 45 and 90 degrees f) to use it! We applied this to our stamped concrete patio per instructions. First we power washed the patio to get the dirt and grime of the winter off (before first photo for before). Then we used a garden sprayer to apply a flood coat of the sealant and let it dry. It dri...
