Stone Master Molds Rubber Molds for Concrete, Retaining Wall Block Mold, Creates Two 11.5" Blocks

These things are awesome. I originally bought 3 molds because someone said an 80lb bag would do six blocks... I found out that the 11.5 blocks I get 2 molds or 4 blocks total. I got one more so I can do 8 blocks a day. It’s extremely simple to use... just mix fill and let them sit over night. Buy concrete in bulk at 3.45 an 80 lb bag and it cost $0.86 per brick compaired to the $2.60 per at HD. Oh yeah, the release of these molds is amazing! Some of the other molds I’ve used require a release agent to get these bad boys out. All I’ve had to do with these molds is flip them upside down, and pull the mold off like a glove. Final product comes out very nice!

I could not be more pleased with this purchase, only if the price was a bit less. They do take on whatever color is used in the mixture, but 50% of it washed out even after a few days. Buy multiple units as an 80# bag of sakcrete mix will yield enough for 4-1/2 blocks.... and I hate to waste anything. I have 3 and may buy a 4th just to make the mixture process more worthwhile. Relatively easy to de-mold the dried blocks, just flip it over and wiggle the lip up

Never been happier when the reviews and product description match up perfectly. Shipped fast, and no release agent needed. Just mix, pour, set and remove next day. I was using 90lbs bags from the blue box store but only got a total of 5 blocks out. My mixing ratio my be off to get more blocks out of each bag but couldnt be happier. Make sure to have a level surface before pouring.

I purchased two of these because I wasn't sure how many I would need for each 80 lb bag (Turns out someone else asked later and it's 6.6, so it's a good thing that I'm making walkway stones as well). I took out my first four today, and they came out really easy, and have a really nice look to them. My mixer only holds 1 - 80 lb bag at a time, and I wanted to have multicolored stones. I'll add pictures later, but they set up really nice and came out really well. Even the wife is happy with them.

I have wall projects all over the yard and love to have the creative edge to make my own mark. The mold is top quality and delighted that with pennies to the dollar, I can afford to make as many as I want. It will pay for itself after I use it 15 times. I'll let you know in what condition the mold is in after 15 uses.

I bought these a few months back but am just now starting to use them. Pour concrete in afternoon and blocks set overnight. Blocks are very easy to release from mold and cleanup is a breeze. I'm trying to perfect the ration of concrete to water for the exact amounts to make the two blocks. My guess is that it takes about 15-20 minutes to mix the concrete and pour into the mold.I now need to get a cheaper source of concrete than the 60 pound bags I'm buying now. At this rate I save about a $1.00 on each block which is not that great. I'll go to the 80 pound bags next and save even more.

Great product, easy to use. I was able to make some slight incline adjustments with the concrete making an ever so slight not to level wall level. Awesome.

I made a stone, it's coolConcrete gets real hot, so splash water on it. And don't let any dry on your dog, or he will be tired always from the added weight.
