Red Devil 0645, 5.5-Ounce Premix Concrete Patch, Squeeze Tube, Gray

Seems like a good product when you don’t want to hassle with mortar/cement mix. Agree with one reviewer who said product doesn’t come out of the tube without a good bit of effort. I think this is partly due to the water content in this pre-mixed variety, which seems pretty low. I didn’t add any water before applying and I also decided to use my fingers to work it into the block foundation I was repairing. That work nicely, much better than the spackle knife/trowel. My trick to get the product out of the tube if you have trouble is this, cut the nozzle as close to the main tube body as you can, use your foot with a shoe or boot on and then slowly apply pressure and product will easily dispense with your weight. I then used my fingers as needed to apply, but you could try applying with a tool. I just found that not great with this mix and cleanup is easy with water so no worries. I did detect a smell of slight acetone or something, I assume something which makes the cement more pliable to get it out of the tube. It’s not real strong but it is there. I would buy this again. I used 3-4 full tubes on my project and since I bought the 12 pack, I have several left. I would recommend using a whole tube at a time as concrete could be very tough to work with after recapping. I have a trick there too. I always take a little cling wrap and put it over the nozzle, then put a small rubber band around that toward where the nozzle meets the tube, only then do I cap it. That seems to typically keep all my tube caulk/cement pliable a long time after resealing. Hopefully product will dry fully and give me many good years of secure foundation.

I ordered a case from Amazon Warehouse deals and it only had 11 tubes in the box. I didn't want to return it because I needed it that day. I had to add a lil water into the tube and knead it until the consistency was easy to work with, making it much easier to fill in some cracks. Dries really hard and I like the texture. Hopefully its flexible like it claims but only time will tell. It's not too easy to squeeze from these tubes. Adding water made it easier, however I regret not buying the caulk tubes.

I've used this to patch inside and out. So far so good. I bought the 12 pack of tubes. Only half of them had caps so hang on to those.

Little too thick but squeeze out of tube so application is a challenge. Product works well for patching missing mortar in front porch. Read prior reviews about end of tube exploding so folder end over like a toothpaste tube. But it takes a LOT of strength to squeeze. I'm 74 so it was difficult.

I thought I could use it to fill a few holes in my cement patio. It was difficult to squeeze (at least for me) it’s very thick and comes out a small hole in tube. Then to try and spread it was difficult. Kept sticking to the small metal flat to spread it. Also takes a while to harden.
