Sidewalk repair

[This review was collected as part of a promotion.] Another quality product from a brand you know and trust. I used this for a small sidewalk repair. Easy to use, quick to cure, and has lasted thus far (1 month).

Really good sealent

[This review was collected as part of a promotion.] Coverage on this is exceptional, stability and the application are quite impressive and easy to apply. Flexibility is nothing out of the ordinary and curing is good.

Good product

[This review was collected as part of a promotion.] The application process is straightforward and with a regular caulk gun. It is a little thick need a little more steady hand and pressure to apply.

Great product!

[This review was collected as part of a promotion.] Great product! I did an addition on my home and needed some sealant to fix a few spots and this stuff works great! It fits in a normal caulk gun and the workability is great! I was able to spread the product with a putty knife in some places as well with ease!

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.
