About Rain Guard Water Sealers SP-4004 Concrete Sealer 1 Gallon
Overall Feedback:
93% positive
86% praised for its strong adhesive, while 14% found it didn't hold well
I have noticed that the adhesive strength of the hardware-sealer is good enough to make the cement waterproof.
The hardware-sealer has good adhesive strength. When water was spilled on the cement, it beaded up like plastic.
The product left my stain tacky and caused it to reverse cure with no way to fix the damage.
91% found it easy to apply
I find the product easy to apply and it is working as advertised.
I found the product easy to mix and apply.
I found the application process of this product easy. I mixed the concentrate with water in a 5-gallon bucket and applied it to my driveway using a pump sprayer in two passes oriented at right angles.
The product is very easy to use, just spray on.

89% appreciated its fast drying time, but 11% had to wait too long
The hardware-sealer dried overnight and when water was spilled on it the next day, it beaded up like the cement was plastic.
When the product dries, there is only a slight beading of water during subsequent rainfalls.
86% liked its flexibility
The sealer is flexible and does not penetrate the concrete even when the pavers are wet from the storm.
87% appreciated its moisture resistance, but 13% found it let water in
The sealer has good moisture resistance as water beads up and runs in rivulets down to the street when it rains, and it is not slippery to walk on when it's wet.
The concrete pavers are wet from the storm but the product is not penetrating the concrete, indicating moisture resistance.
I have not tested the water resistance of the product yet since it has not rained since applying it.
I applied two coats and tested the moisture resistance by spraying water on the floor. It beaded up, but when I rubbed it with my hand, the concrete became wet.

85% praised for its long shelf life, while 15% found it expired quickly
I am waiting to see how the product holds up by next summer, but I think I will get some protection. The product was able to absorb into the previously treated concrete.
I plan to purchase and apply more of it after 3 years, indicating its 3-year shelf life.
I am curious about how long the product will last before needing another coat.
The old oil-based sealer was difficult to apply and clean and only lasted for 1 year.
