These are very well made and durable. I did 7 batches in them and they look like the day i bought them. I would say keep them out of sunlight as UV would likely damage them eventually.Using a 66lb/30kg bag of quickcrete with the max recommended water ratio works great. It fills 1 set of molds perfectly, and it’s liquid enough to minimize bubbles. I vibrated the molds with an oscillating tool after filling to remove the bubbles completely. I broke the first stone i tried to remove after 12 hrs. I waited 24hrs for the remainder of the stones and had no issues. The stones do remain somewhat fragile for 48 hrs total.Bees wax seemed to be the best mold release agent. I applied with a hair dryer and paintbrush, then washed the molds after use, then reheated the bees wax. I only had one mold which was difficult to release using this method, but i suspect I didn’t clean the corners well enough.I dyed my stones different colours to match my house using a combo of Charcoal and Red concrete dyes. I suspect you could also use any water based clothing dye as well although I never tried that. I found the pure red concrete dye seemed to cause many more bubbles even after vibrating.All in all they turned out great, and I’m very happy with the result.They cut fairly easily using a masonry blade on an angle grinder.With only 1 set of molds this was fairly time consuming, but very cheap for what you get in the end.The picture is just a rough layout, not a final install with cut stones.Enjoy!

This was an excellent opportunity to learn about concrete. I got it down to one 20kg (44.1lb) bag plus another 4kg (8.8lb). Total 24kg (52.9lbs) of high strength concrete mix. 6 bags make 5 sets. This means the molds are filled to about 1/2" from the top, but this equals less cost, weight and mess.I grease the mold with coconut oil, and clean the molds after each use. Bubbles in the concrete mix can be an issue, so a defoamer admix or vibrating table helps.To cure the concrete I leave it in the mold with plastic wrap over it for a full week. I'm not in a hurry.

25 mètres carrés ! belle terrasse, c'est beaucoup de travail pour réaliser une telle surface, mais le résultat est parfait. Une douzaine d'heures pour laisser prendre le béton à chaque série, il faut la place, ensuite il faut le stockage, ensuite la pose avec les découpes. J'ai posé les dalles sur une surface bien lisse, calées avec du sable bien fin. Les couleurs diminuent au fil des mois, mais cela reste original et joli.

Very happy with these molds. The product arrived within two weeks and was well packaged. I started with one mold set last year and was mixing concrete in a 5 gallon bucket. My original plan was to pour enough for a 24x24 patio but decided to put a pool in the back yard this spring.I purchased a second mold set and a concrete mixer earlier this spring and was able to pour 12 stones a day.A single mold set will accept a 60 lbs bag of concrete. This will fill 6 stones. I decided to go with 60 lbs sand mix concrete from a local hardware store for a few reasons. It does not have rock aggregate that can ruin the appearance of finished stones but the sand aggregate is strong enough to hold together without breaking. (Sand mix is normally used to resurface driveways and is robust up to 2" thick. The molds are about 1.5 inches thick so sand mix fits the bill perfectly and is relatively inexpensive)As with some other comments, you will need to mix the concrete as a wet slurry, pour into the molds and shake the mold to remove the air pockets, lightly lifting and dropping the molds on a hard surface does the trick, or you can make a concrete vibrating table (even better)One 60 lbs bag of sand mix concrete is $5.50. In theory each stone costs less than $1 to make. You can also stain the concrete by mixing dark latex paint in with the concrete/water mix to get a variation of colors. Typically I look for returned paint at the local hardware store as they sell one gallon paint for under 10 bucks.Keep in mind. This is labor intensive, the concrete mixer definately helps speed up the process. I can pour 12 stones in 20 minutes. You will also need to purchase cooking spray in bulk to coat the molds before each use so the concrete wont stick.All in all, it is a super product and allows the chance to have a unique patio for a fraction of the cost of purchasing stone at a masonry supplier. I highly recommend and the finished project shows.

Update - I stopped using Pam cooking spray and have begun using corn oil. Reason being, the Pam would cause small air bubbles which ended up on the top of the stone. Instead, I just pour a small amount of corn oil into the mould and then wipe it all around the inside. I also figured out that just scooping a small amount of concrete into the mould while it is on the vibrating table will allow the air bubbles to escape much better. The concrete kind of bleeds out and covers the entire mould. Then just add a bit more concrete and wait for bubbles to dissipate, then add some more and so on. I am using Quickrete 5000 High Early Strength concrete from Home Depot. Through my Home Depot app the 80# bag is $3.98, but in the store it's $6+. I am also using Rapid Set Concrete Pharmacy Flow Control, one 2oz. bag per bag of cement. Three quarts of clean cold water (mark a gallon container on the outside with a sharpie and you'll have the same mix each time). I use the Quickrete color additive also, but using one container for about four bags of concrete. I picked up a 1 1/4 cubic foot cement mixer from Harbor Freight for $169 - 20% coupon and it mixes one bag at a time. Keep in mind that there will be a bit of leftover concrete from each bag, so either toss it or subtract a little mix and water. I have some other moulds that I am making so the excess goes into those extra moulds. For my setup I bought 3/4" plywood and six 2x4s. Cut the 4x8 plywood in half to make two 2x8 tables and supported them with the 2x4s cut into two foot lengths. I took an old hand sander and strapped it to the top of the table on one end and then I pour and vibrate on that end, then move the filled moulds to the opposite end of the table. Let the set for 12 hours and then make another set. They are hard ABS plastic and seem to hold up very well. The first pour were a bit tough to release from the moulds, but every pour thereafter has been a very easy release. It's down to a science now and I'm considering purchasing another set of these moulds to speed up the manufacturing process - I need 160 of these stones. They shipped super fast from Kiev. And to the manufacturer of these moulds - thank you very much. You've provided a very decent product at a reasonable price and your attention to order processing and shipping is noticeably prompt. Kudos.
