Rigid ABS plastic molds for concrete can be good if taken care of properly. I have seen many who would prefer to have silicone.These are not small. I thought they would be a little smaller but instead these are about 2 ft in width. That is a lot of concrete. I have used molds for many different purposes, these are my first concrete molds. I am going to experiment with premixed store bought concrete mix and several mixes I have found online. I am also going to use the concrete resin or whatever it is called to make these less prone to the elements. Stains or colors to make these look more like wood will also be looked into.According to all of the information gathered from ty, big box store "L" ow es and also H Depot (if you live in the US I think you know what I mean) and other websites; play sand will be needed to add support and something that can support the mold when turning it over will greatly increase the lifespan of these molds.For the weight of concrete to go into these molds, they should have been somewhat sturdier and more durable. I may use a trick I learned with other molds that I have used and purchase more silicone mold making materials. I can use this material to create a silicone mold and even create some type of support for that as well.Mold release is needed. For ABS plastic, I may just use my plaster and clay mold release. Instructions say you can use engine oil but this is not typically recommended for ABS plastic nor for anything that will be going outside. Any cooking oil is alright to use but still not the best. Environment friendly plaster and clay mold release should be the best. I can not see why these should not work for concrete. Most concrete forms used in construction use different forms of releases. A lot of oil or mold release is not needed. Using a spray cooking oil like "Pam" or other brands will work, just do not use types that have "flour" also inside.Prepare for a lot of concrete. If mixing your own then prepare for needing a lot to fill these molds. Have something to assist in "flipping" these over because they will be heavy. I will be using a plastic tote, filled with slightly wet play sand to be supporting the molds. I can use a slightly larger tote to "flip" these and catch all the sand at the same time.I will update as soon as I have completed a few dozen and will do my best to have photos of how these came out.

Not super impressed with these molds. I wanted to used them to make a bunch of pavers to outline a walkway in our yard. There are a few issues with these molds. The first one is the material, they are made out of a very thin and brittle plastic that I have a seriously hard time picturing holding up to the abuse of multiple batches. The second issue is that both of these molds are exact copies. So don't expect any variation in your patio stones. If I had to make a choice, I would spend more money and get a nice heavy duty silicone mold instead.

It's nice that it's a set and not just one so you can have multiple molds going at a time.I'd say it could be heavier duty but I believe it is actually better to be a little thinner as it allows you to flex the mold off the step/paver easier.The grain structure looks like and is really well defined.You can color the materials as you see fit so you can stain your steps to the color you want.I haven't run one to failure so I expect they will have a long life.

I have a backyard pathway that I've been wanting to replace but haven't found what I want to do with it...until now. This comes as a pack of 2. That's a huge drawback. Unless your project includes only 2 concrete pavers, you'll need to be VERY patient. The 2 molds are not big enough to hold a full bag of concrete. With my test, 1 mold was about 1/4 of a bag, so 1/2 bag for 2. They need to cure for 24 hours before removing...2 concrete pavers...every 24 hours. I've got the time, but be aware that you'll want more if you don't want to wait a year to complete your project. I've used concrete molds like this before making concrete counter tops. Use a "release" agent to allow the mold to release the concrete paver. I use WD-40, but I'm sure other things will work as well. You also may want to consider using short steel rods within the concrete to increase the strength. Concrete will crack under pressure so adding rigidity within the paver will help the durability and prevent cracking. Make sure to "vibrate" the concrete to eliminate any holes. They make huge tools for this, but running an orbital or something similar against the form in different places seem to suffice. Be careful when removing the mold from the paver. The plastic is thicker but it will tear and your mold will need some duct tape. These make a nice size paver. I have a large project. One paver down, 96 to go. Maybe I'll have enough to finish by spring.
