Decent cure-time and maintains its flexibility. Adhers pretty well and decent water proofing.

Works

[This review was collected as part of a promotion.] This sealant works perfect. I have used it several times and it always gets the job done. It holds well and does not just pull apart. It has a very smooth texture.

Good at sealing window

[This review was collected as part of a promotion.] Very good sealant!! Works well on doors and windows and it makes it nearly impossible for water to break through and enter your house. I have used this also on a few cracks on my porch and it seems to have helped with the moisture issue.

Great for small cracks

[This review was collected as part of a promotion.] I do like the fact that limestone polyurethane dries almost the same color as the concrete that is sun faded. It was supper simple to apply after some small amount of prep work. It was very thick when applying which and tooling and smooth this into the cracks easier. It has held up to the very mild summer I have had so far but want to see how it Fairs in the winter. I have recived this product for free for my honest opinion.

I'll Be Back

[This review was collected as part of a promotion.] I can't leave an honest review at this time. I have not had a chance to use it. Between the heat and the rain, I have not been able to use it. I will come back with photos and a review, hopefully this weekend.

Our go to product for concrete and Masonry repairs

[This review was collected as part of a promotion.] There’s not much that’s fun to say about this product except that it does exactly what I expected to do. We repaired a brick pillar mailbox that was hit by a car and this has held up nicely. I waited a few weeks to make sure that it cured well and indeed it did. It was easy to apply. Great consistency.

Wow

[This review was collected as part of a promotion.] Lots of functionality from this small but large package. Workability lasts long time as it doesn’t dry instantly. Quality you would expect from locktite. A must.

Very hard to use, doesn’t come out very easy.

[This review was collected as part of a promotion.] I tried the Loctite PL concrete non-SAG limestone polyurethane sealant. I don’t know if I got a bad tube or if it’s the way it actually is. I couldn’t squeeze hard enough to get it to come out of the tube. I had to have my husband squeeze it and he even had a difficult time. We cut the tip again for a wider flow and it was still difficult. It is definitely thick not runny. I think it could be a great product if it were easier to use.

Bad tube

[This review was collected as part of a promotion.] Product was extremely difficult to get out. I'm assuming it was on the older side. After about forcing half the tube out for an hour, the second half came out very easily. I had to cut it three separate times thinking maybe my hole is too small. After the third cut I knew it was going to take some time getting it out. I didn't quite get past half way so I will need about two more tubes. Very sticky stuff and it takes a while to dry. As of now i...

Excellent adhesion, easy application, and a realistic limestone color make this a great sealant for clean durable masonry repairs.

[This review was collected as part of a promotion.] I received the Loctite PL Non-Sag Concrete Polyurethane Sealant in Limestone in exchange for my honest review, and I came away genuinely impressed with its performance. I used it to reseal the joints on my outdoor granite staircase, and the Limestone color blended in surprisingly well with the existing stone, giving the repair a much cleaner and more finished appearance. The non-sag formula was exactly what I needed for these vertical and angle...

Amaing hold and no messy drips

[This review was collected as part of a promotion.] I recently used the Loctite PL Concrete Non-Sag Polyurethane Sealant for my project around my house, and it exceeded my expectación. I love most about it is the "non-sag" . It stays exactly where I pu it, even on vertical walks and foundations, without running or drpping everywhete. It files crack beautifully and cures into a very durable, weather-resistant sea. It's incredibly essy to apply with stand caulking gun. If you need a reliable, hev...

Slow drying and hard to squeeze out of the tube

[This review was collected as part of a promotion.] This product is ok. It is very hard to get it to come out of the tube. Not sure if it was old product or if it is always so thick that it doesn't want to come out. It worked good for my needs. I do not like the curing and dry time. Takes days to cure. Other than that it works. Hopefully it holds strong in all types of weather.

Super Sealer!

[This review was collected as part of a promotion.] I used the Loctite Concrete Sealant for an outdoor project on my front steps. The odorless sealant was very thick, but super easy to apply. It flowed from the tube smoothly and evenly with strong bonding abilities. It adheres and cleans up quickly. The sealant has been completely moisture resistant since application. Highly recommend!
