Rated 3.5 out of 5 by 14 reviewers.
Rated 4.0 out of 5.0 by Brick mortar cracks Used this product to weather seal some cracks between brick mortar, and I was very pleased. It matched my standard gray mortar very well, and was just the right consistency to work with on vertical surfaces. With latex gloves on, I recommend just using your fingertip to lightly stir the edges to blend, and wipe with a paper towel as you go. This technique worked best for me. I have yet to use this on a horizontal surface, but I would imagine it would best be suited for larger cracks. I feel like a product that is little more viscous would be better for tiny horizontal cracks. September 2, 2013
Rated 3.0 out of 5.0 by Uggh Pain to get out of the tube. I don't know if I got a bad batch or what, took forever to squeeze out of tube with caulk gun. Otherwise seems ok. No instructions on whether it is ok for it to rain after so many hours. It is waterproof but can it rain the same day??? July 23, 2015
Rated 4.0 out of 5.0 by Good product but not gray color I just used the sealant today to repair a stem wall that is separating from my house that was not repaired well last year and is failing again. I stuffed the cracks with pieces of foam pipe insulation, then caulked. It did not drip or run so that was great. But the color is very light, beige-like. After several hours I went out and touched a surface and it was still wet. So I expect it to take at least a week to cure. (Package says cannot be painted until 7 days. I will wait 14.) I used a tongue depressor to smooth the joints and that worked well. I just hope it dries to a darker color even though I plan to paint it. It had a nice stickiness and applied easily. Make sure you puncture the tube after cutting the tip. It was not hard to push out of the tube. October 4, 2013
Rated 1.0 out of 5.0 by Extremely Long Cure Time I am awaiting guidance from Loctite technical services regarding the cure time on this product. I applied it to a small fault line in my basement masonry floor, waited 7 days before painting the floor with Valspar Porch and Floor paint (oil), which is outstanding, by the way. The sealant was still a bit tacky, so perhaps I should not have painted it just yet. Anyway, after the paint dried, I discovered that where the paint had been applied over the slightly tacky sealant, I am able to wipe the oil paint off with a towel dampened with paint thinner.

Rated 4.0 out of 5.0 by Good Sealant on exterior surfaces applied to vertical and horizontal cracks on external chimney. sealed very well. Applied to cracks on driveway. Sealed very well. I was so impressed with product that I used it as an above the water line adhesive sealant caulk agent to beneath the stanchions plates and main sheet track my 25" sloop. Once dried extremely water resistant and remains flexible. during rough weather. Beige color match was excellent. material remains flexible. Good bonding to metal and gelcoat surface. Mineral sprits makes an Eeasy cleanup on gel coat and stainless steel. November 15, 2014
Rated 4.0 out of 5.0 by Easy to use this BEIGE sealant This sealant was easy to use as long as you read the directions and punctured the seal on the tube before using it. I actually liked the beige color because it blended in nicely with my walkway. It is VERY sticky and doesn't self-tool, but that wasn't a problem, I just wore gloves (as per instructions) and ran my finger along the seams to smooth them out, and they look great! I ALMOST wish I had more cracks in the walkway to use more of this stuff, almost....... November 12, 2013
Rated 1.0 out of 5.0 by Would not flow from caulk tube I bought a new tube, cut and pierced it like I always do, and it would not flow from the tube. The caulk tube was bent and damaged from my caulk gun, but still no sealant came out. I would not purchase this brand again. I have used the Sika product before without any problems.

Rated 5.0 out of 5.0 by Great Sealant It stopped the leak in my basement. I had to use two tubes, but I am pleased with the results. January 28, 2014
