Great for Concrete and Pavers in the PNW Rains
I recently used MasonryDefender Concrete Sealer on our concrete pavers and patio, and I couldn’t be more impressed with the results. Living in the Pacific Northwest, where rain is a constant, our patio and driveway were constantly getting soaked and stained. After applying this Silane Siloxane-based sealer, the difference has been remarkable.Water Repellency & Protection:The sealer is incredibly effective at creating a deep, penetrating barrier that prevents water from soaking into the concrete. After application, I noticed that water now beads up and rolls off the surface, even with the heavy, consistent rains we get here. It's like our patio has a protective shield against moisture, which not only keeps the surface dry but also prevents potential damage from water infiltration, such as cracks and discoloration.Easy to Apply & Long-Lasting:Applying the sealer was straightforward, and the 2.5-gallon size was more than enough to cover our entire patio and driveway. It dries quickly and doesn’t leave any sticky residue or odd finish—just a smooth, invisible protection that doesn’t alter the appearance of the concrete. I’m confident it will provide long-lasting protection for our surfaces, especially during the wet months when they are most vulnerable.Great for Concrete Pavers:We also have concrete pavers in our backyard, and this sealer has been fantastic for them as well. The pavers no longer absorb water, which means no more staining or deterioration from rainwater.Overall:I’m thoroughly pleased with the MasonryDefender Concrete Sealer and would highly recommend it to anyone in the Pacific Northwest (or anywhere with a lot of rain) who wants to protect their concrete and pavers. It’s an excellent investment to keep your outdoor spaces looking great and standing up to the elements year-round!

Works as advertised and easy to apply.
After power washing my dirty driveway I applied this sealer. It was easy to apply with my garden sprayer. Once dry the driveway looks great. Rain water beads up, yet it is not slippery at all. Easy clean up with water.

Reviews are true
I read through most of the reviews, good and bad, and both sides are correct. I used the product on my concrete patio that has previously been powerwashed. The product does repel rain and water very well, I‘m happy with the outcome and will probably repeat the process once a year. It was easy to apply and only took me 10 minutes. The bad news is that I did get some staining due to overapplication in some areas that I sprayed twice. But that was my mistake. The staining looks like it is wet, it‘s not ugly or oily stains. I will buy it again

Good sealant
I reviewed many products before going with this one. It's a bit pricey, but it works! I used it on my driveway and it looks so much better, even months later. It hasn't gotten dingy and dirty looking as it has prior to sealing it. It's easy to use and has lasted several months.

Still happy after one year
It's been almost a year since we put in the new driveway and sealed it with MasonryDefender Concrete Sealer. It's held up very well. Rain still beads up somewhat and does not soak right away into the concrete. There are no cracks or stains. Really pleased with this product. It was recommended by This Old House. The seller was awsome to work with too, they expedited the shippment when there was a shipping delay. We got the product in time before the leaves dropped.

Great Product
I really like this product. Where I have applied it, I can see the rain water beading up instead of soaking into the cement. It does seem to work best if you apply it in warm weather.

Save your concrete (steps)
Absorbs into concrete well. Recommend a small garden sprayer to apply. Doesn't change the color of concrete

Unresponsive seller and BLOTCHY sealer.
Seller did not ship the correct number of jugs of product. I ordered 5 and only 4 arrived. Seller has not responded to any of my attempts to contact them and has not provided a refund for the missing item.ALSO, as other users have noted. The product ended up looking BLOTCHY on the concrete. Parts of the concrete has a slight wet look, while others look dry. The blotches are random and I can't find a way to fix them.
