Used to coat a very large old fountain and it worked magic on the piece. I thought there was no hope for the fountain when we bought the house - cracked, chipped, and overall in bad shape. But because it was so big and would require a backhoe or jack hammer or both to get it out of the ground I wanted to try and salvage it. Paint did little to hide the damage so I put it on hold until I came across this mortar when I was researching a different project. Thought I'd give it a try and I was amazed how well it worked. I used a roller to apply it, then smoothed it over with another dry roller to knock down some of the texture. All in all, very easy. I do recommend a paddle mixer to get a smooth texture. A float and regular cement tools work as well for applying it.

It didn't do what it says it does?
Bought this because had some seeping thru block walls in my basement. I dried the area ahead of time as stated, applied via trowel to 1/8" per specification and then rolled a 2nd layer. I purchased this because it was said to seal in the water, but still allow the concrete to breath. Doesnt make sense to me either but gave it a go anyway. I still have the exact same issue. It doesn't work for what it's said to work for. I'm not one to typically leave reviews, but remove this from the shelves...

This product is super easy to mix and apply. I love making concrete projects for my garden but in the PNW, it rains so much that they end up taking in rain water and eventually crumble. I am hoping i have found the solution for this. Last week i coated my garden orb with this waterproofing mortar. I know this isn't the normal use for this product, but i think it can solve my soaking and crumbling for my little pinterest projects. I will come back and update my review after the fall to see if my orb is still in great shape.

This is an easy to use product that mixes well to a smooth almost putty-like texture and spreads easily and sticks well to any concrete surface. It dries to a very dense and hard surface and can be worked to a very smooth finish to make an attractive repair. The material appears very non-porous and durable on my basement steps. It should be usable for patches as well as waterproofing.

This waterproofing mortar is easy to mix and apply following the directions but the procedure was more extensive than my previous waterproofing efforts. My application was all near the floor, where the floor turns to wall and for about a foot up the wall in an area set off to stop seepage across the cellar from exposed ledge in our basement, predominantly in the spring. Over the years I have gotten adept at cleaning and re-cleaning this area before applying previous coatings. This material is different than any of the previous products I have used and while the prep work was still a chore and the procedure extended I have a good feeling about this product.

I used the mortar to fix a couple spots in our garage. The powder is very consistent and it mixes easily with water. The mortar sets fairly quickly, but I gave it at least 24 hours before driving over. We will see how long it lasts but I am pleased with the result so far and how easy it was to work with and clean up. The dry mix doesn't have any added rocks or large particles, so it allows you to create a very smooth finish.

This product arrived as a 50 bag inside a nice, solid white bucket. The bucket would have been great to mix large batches of mortar, but since I'm a female, amateur, I work too slow for this mortar's dry time; so I used a bowl to mix 1 cup of mix with approximately 1/3 cup of water. Although this made for about 50 batches, it was relaxing to work at my own pace. You'll see that I tried to patch sections of my rock wall and driveway crack a couple of years ago using a quickcrete product. That motrar crumbled like chalk and was virtually all lost within 3 years. My initial opinion is that this product seemed more solid. During the heat of the day (sunny high 70s), I did spray down my patches to slow their drying to prevent cracking. Once dry, the mortar hardened to a rock solid consistency like a cement - not chalky mortar. I'm excited that this product is waterproof. I think it should make a dramatic difference in it's longevity and will protect the integrity of my wall structure for years to come.

The 50 Pound Rapid Set Waterproofing bucket is just what the doctor ordered when you need this product to stop water. We had a series of storms back in April and identified areas that were leaking and we were able to waterproof the entire area with ease. REMEMBER that you need to wait 3-5 days before exposing the product to hydro static pressure so this is not an emergency quick fix product. What I love is that you have 30 minutes of working time and this allows you to complete the job the right way!

The waterproofing mortar arrived (in a cardboard box and sealed in a five gallon plastic container - obviously to keep the mortar dry) and since it is a fifty pound container it is still on my porch. Waiting for a few good, no rain, weather days so that I can apply it to the cinder block foundation of my front porch. I plan to use this mortar outside and inside to completely waterproof the area of my basement that is in need of some repair. This is going to be the perfect product to handle this repair.
