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

These molds are excellent! The sizing is exactly as expected, and they’re lightweight and easy to work with. With a light coat of vegetable oil, the concrete releases effortlessly from the molds. The results are both beautiful and functional, making them perfect for creating a great-looking sidewalk.

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.

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.

EDIT:Gave up after yesterday's hour plus to demold the 6 pieces & ordered 1.25 tons of genuine flagstone. It is not worth the aggrevation with demolding time... even using a blow dryer to heat the mold in attempt to make demold easier.=====================While we really like the molds, they are a bit overpriced though an undisclosed fact is they are shipped from Ukraine; thus the difference in Amazon text have it next week but reality is much longer & shipped in a way where tracking is non functional.Demold is a real pain. Takes us about half hour to demold the entire set. BTW, just found that a hair dryer to heat the mold helps immensely if you get out of the wind to apply the heat.

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.
