Concrete water sealant
Haven’t seemed it rained on yet but easy to apply. Hopefully it will keep water from soaking in.

Follow directions. No issue
This was very easy to apply. Be aware it is very watery. I poured some in my birdbath and actually put to much but I just kept painting with it til I used it up as it dried. I allowed to dry like directions said for 24 hours and it has worked perfectly.

Very pleased
I used the product on my front porch steps and my large back patio. Both are colored stamped concrete. Easy to apply. Thorough coverage. Surprisingly pleasant smell with no noxious fumes. Excellent water repellent without being slippery. I'll be curious to see how it holds up to harsh Midwestern weather extremes. Very happy so far. The price was reasonable

Easy to apply
Not only is it easy to apply but it looks great too. Be sure to power wash first with a good industrial cleanser and resand with engineered sand if doing a brick patio. It might take 6 or 7 sweepings to get all the sand settled and the excess off the surface.

I bought a solid concrete bird bath. The manufacturer recommended a Behr product that was almost twice the price. This Amazon concrete sealer worked very will. Follow the directions as written...prepare the concrete with cleaning and drying it. Then I applied with a brush on all surfaces except underneath... the concrete has to breath. Make sure not to create puddles by repetitive brushing it around. Then I kept applying another coat before it completely dried within 2 hours. The concrete did take on a slightly darker appearance as if you applied a clear satin finish. No change in colour though. Allowed to dry for two days before adding the water. After a full season of water in the birdbath I cleaned it for winter and no water marks were evident. Easy to clean as well. Lots of sealer left over in the container to repeat the process in a year or two. Highly recommended.

I bought the smaller jug of sealer as I do concrete craft projects, previously i paid about $110 for a pail of concrete sealer at my local hardware store and sadly over 6 months of Canadian winter in the garage it congealed and went bad possibly due to weather or a bad seal on the tin can, i like that this comes in a small jug with easy closure and now i can store this in my craft room rather than the garage, product looked exactly like the expensive one i previously purchased and had no problems with application, because i use this for garden stones i can’t really comment on durability for large products but it definatley did the trick for what i needed it for

It was easy to apply. Went deep into cracks (sealed a concrete dragan). Would recommend this size for small concrete items. Would easily cover the area stated.

Meh. Did the job, lasted one year. Am now using 3% vinegar.
