SvitMolds Concrete molds DIY Sold 6 pcs Plastic Moulds Flagstone Casting Concrete Paving Garden Paths Stone Patio Pavers for Garden Walkway #S34

Excellent product. The molds are very durable and easy to use. After making more than a hundred stones the molds showed no wear. The finished pieces were very realistic looking and quite attractive.

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.

I love these. I used old cooking oil (canola and olive) as mold release and swooshed a bit on paper towel to help get the concrete hardened out of the molds. I also used a massager, the log kind for athletes wrapped in a trash bag to keep it clean, and put a cat litter box on top of it upside down, then put a mold at a time on top of that, to shake out the bubbles that form (cheap shaker table). Home Depot, maybe Amazon too, sells polypropylene sheets about 1/2” or so thick, that replace the slag you would normally put under pavers. Saves your back. The patio I made was about 45 bags of 50 pound each high strength crack resistant concrete. I am not strong enough to move 80 pound bags (a lady). Screed the sand, put down a barrier layer, and tamp down the pavers. I dyed some of them at random. I used pigments but heard you can just add paint too. Took 24 sun hours for them to cure completely, and for a few, instead of cutting with a saw, I used popsicle sticks to partition where I wanted a half sized piece, and forced them into the mold once the concrete had started to set. For filler around the pavers, I used high grade stuff, ~ $25 a bag near me, not the filler you can get at HD. It is called Polybind dust, comes in 2 colors and fills up to 6” gaps. I used it on my driveway too, rather than the caulk filler many use when spaces between concrete are a trip hazard. Have had patio 2 summers now. Looks great. Sealed it with some high $$ stuff. Not one weed came up, and I live near woods. Awesome product. Buy two sets if you can, of molds. Work goes faster. Peace. ADDED A THIRD PHOTO 10/22/2024. THESE ARE THE PAVERS TWO YEARS LATER. IT IS FALL, THEY HAVE NEVER HAD A WEED, and HOLD UP GREAT.

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.
