This is a great mold set so you can make your own stone bricks. The only reason I gave it a four is because its extremely hard to get it out once the cement cures. Even if you use oil or wax. I think Im going to have to open two of the mold corners to easily remove the it. I wish the were make with scillocone rubber, not plastic. Other than that, I expect these molds to last a long time but only time and use will tell

Very thin in spots. All concrete in molds cracked with 3 pours of sand / cement mix. I've attempted three times with these molds with this mixture. I then bought several other add water bags of cement and they all cracked EXCEPT for 1. I used Quikcerete Fast Setting in a red bag from Lowe's. Worked GREAT!!!!! I started to give 2 stars but must change to 5. I rigged up a cheap vibrating table that I seen on YouTube with a tire and a sander and they came out awesome. Would definitely purchase again.

Works great, but I found brushing in liberal amounts of vegetable oil works best as a mold release. They slide right out, and any excess coats the sidewalks when concrete inserted. Also veggie oil helps clean the residue for next round of brick making. Ready to remove in around 24 hours... reduces breaks drastically.

9 molds used approximated 3/4 bag of 80 lb concrete bag. I add stain to. Oncrete mix, and black stain to mold just prior to pouring concrete.... awesome results.

I'm ordering more molds next month! Easy to use after short learning curve

I LOVE THIS MOLD!!! I have read most of the results before and after purchasing. So to the point.
Patience!!- don't believe too quick to remove from mold. The cement used is most impossible as they tend to break a lot. It was after my 4th set that I got results. Issues were below;
1. Was only using sand and cement and was mixing ratio 3sand:1cement( this was TOO WEAK) - when I use more cement it dries faster.
2. I did not give it enough time to dry. takes about 12-16 hours to safely remove castings from molds.

Another issue was that some of the molds are warped, hogging( middle section pushing up). I solved the issue by resting them on chocks at each end so the weight of the concrete presses down the middle by gravity. This works well!!

Also, I used a vibrating table. When they break, if you look closely at the inside lattice( surface) you will see a lot of air pockets. So the vibrating table eliminated that.

I find that cooking oil is a bit too thin and leaves a lot of bubbles even with the vibrating table. A thicker substitute worked for me( 20W40) motor oil.

For a clean professional finish, when I LIGHTLY oiled the molds, right before I pour the concrete, I lightly pour powdered cement to coat the surface, as you would do when baking with flour in the baking trays. I find the finish is VERY smooth and even if bubbles were there before, this would eliminate them.

ENSURE the concrete is mixed thoroughly, using sand, fine gravel and cement. My mixture 3sand:2gravel:2cement. This is so because I don't have "fast setting concrete"( Quickcrete). I researched the components and tested my method. I used ordinary cement.

DO NOT FORCE THE MOLDS OFF. If when you are removing them and they are tight, gently pour warm water over the mold and they will come off easily, but try not to do this as much it may eventually warp the molds.

I colored the concrete mixture but find staining them works for me. It's a very patient hobby. You will get the hang of it after a couple tries, just don't give up!!.
Great stuff and good luck!!

Its ez tu use , it works fine .
