SAKRETE | Concrete & Mortar Dissolver | 28 oz

Made clean-up of a well used concrete saw much easier

Crap. Barely works. Used to be good, used to be green liquid. This arrived yellow. Unsure if it was old/expired or they changed the recipe.

I bought some brown colored stepping blocks and bought some cheap sand to fill in between the blocks. I didn't brush the sand off of the blocks right away and the sand got wet and almost turned into cement.It stuck to the blocks turning the blocks white. I tried to this product to remove the sand and it works pretty good. Just make sure to follow the instructions. It takes a lot of muscle but will be worth it if I can get the blocks back to their original color.

First, follow the directions and it works amazing! I retiled my outdoor kitchen and let’s just say I’m not the neatest person when I’m in project mode. I used this for two things - first I mistakenly got mortar on the front of the porcelain tiles and did not get it cleaned off. Because this is a weekend project, the tile sat with mortar on the surface for a week. Sprayed this stuff on the mortar, let it set, sprayed again, then scrubbed with a steel stripping brush and voila! Clean tiles! Secondly, we have a composite deck and I got mortar and grout on the deck. I scraped all the chunks off, then sprayed this and used a normal scrub brush and it cleaned up fantastic!!My only problem is with Sakrete - I paid $30 for a bottle and not 5 days later, the price has shot up to $41!!! Stuff works great, but don’t pay the price on Amazon. Grainger, Walmart, or Family Hardware has it cheaper!

I really, really wanted this to be a five star review. I saw a YouTube video where a guy sprayed this on a metal sheet with concrete splatter, waited about 15minutes and then hosed it down. The concrete started peeling off with minimal effort and a brush of his hand. That’s what I wanted.What I got was this: I sprayed it on, waited about 15 minutes and then I scrubbed and scrubbed. I sprayed again and scrubbed with a nylon brush. I sprayed again and scrubbed some more. Little pieces came of quickly but the bulk of the splatter was still there. I sprayed again (down to half the bottle now) and started scraping with a putty knife. The photo was taken before I went to the putty knife.Here are a few things to know: 1. It comes in a plastic bottle and despite the packing efforts it will leak a little. Packing was as good as can be expected but open your box and package outside when it comes. 2. Wear rubber gloves when you use it. I’m a man and don’t believe in reading instructions. After rubbing it with my unprotected hands for a while, it started to really irritate my skin. Ouch. 3. Read the instructions carefully and follow them. Yes, it’s a “natural” product but it potent. 4. Use it outside or in a well ventilated area so you don’t breath the fumes. 5. It’s not a spray on and hose off product. It takes lots and lots of elbow grease. 6. If concrete is on a painted surface, it WILL remove the paint as well as the concrete. 7. It worked...sort of. It’s better than scraping dry concrete off with a chisel.All in all I wasn’t disappointed but I wasn’t enamored. Maybe I dint get what I expected because my surface was painted. Maybe I didn’t act soon enough after the splatter got on the door to get it off. (It happened about a month and a half ago). Maybe I just had unreal expectations. In any case, I’d use it again but I will be prepared for some hard work.

Works great for removing concrete splatter

It worked! I have a metal house, barndominium if you will. I hired ca contractor to pour a patio up against my existing building. Septic lines prevented the concrete truck from getting close enough so they used a skid steer to bring the mud to the forms. They splashed concrete on the painted panels of my house. Needless to say, they let it dry and of course it would not come off. This was a wainscoted two color wall and they did replace the bottom sheets as they had too much to try to remove and I wanted a quicker resolution “none of this product available in my local area” That left me with concrete on the bottom “drip rail?”. I was skeptical of this product even after reading the reviews but I was desperate. It did indeed loosen the concrete and allowed me to get it off. It comes out as foam and does require patience as it needs time to work. Small smears dissolved on first application and bigger blobs came off after 2-3 soakings and the paint seems unaffected.

Didn't work that great- I was trying to clean mortar left from Sakrete Polymeric sand from my patio install and it did not remove from the siding at all. The best thing that ended up working was just warm vinegar and water and a copper cleaning pad you would use for cleaning cookware.
