Step 10:

Once the casting material has cured, remove the frame. Once the frame has been completely removed, stand the mold and mother shell on end and carefully remove the mother shell. Once the mother shell has been removed, begin to remove the mold from the cast piece. The Rebound 25 is great in that it has great elasticity but retains it's shape. Be careful as the edges of the cast piece can be razor sharp. Press firmly but slowly on the pieces in the voids to remove the mold from the cast piece. Once half is done it is easier to rotate the piece and start at the top again.

Once the cast piece is completely removed from the mold, clean the mold with Joy dish soap and warm water and store flat in the mother shell.

And now you have a paver through which grass can grow. You can cast this piece out of pretty much any material. If you plan on using something like concrete and want to get more life out of the mold, add two more coats of silicone to the mold.
I'm kinda lost on what this is for. Do you have pics of what you did with it?
u can use foam in a can 4 this as well but u'ill need to work fast tho. for mold-able substrate materiel u might wanna go with paper mashey ( paper in a biodegradable paste ( flour an water mix)). that way yr gass will grow as well.
use a full face respirator as well. so u dont get any in yr face. also use a full rain gear as well. soo u or a loved one can rinse u off after.
Some times known as &quot;Grass-Crete&quot; at least here in the UK, thank you for sharing your project. <br> <br>You've done an excellent job of documenting it and a lot of the molding techniques are applicable to other projects. I do wonder however if you really needed to go with a two stage mold process for this application. I'm sure it could be done just as effectively by constructing the mold as a single female without the intermediate &quot;glove&quot;. <br> <br>Was there a reason for doing it the way you did? Was it just that you had the stuff on hand , wanted to explore your molding techniques, or is there a real TECHNICAL reason that this is a better way to achieve the final result?
Dream Dragon, thanks for the comment. The reason I went with the glove mold was: 1. To illustrate it so someone could use it, and 2. to keep the cost down (though the cost is high as it is). You are right, the mold could have been solid and it would work well. The mold did need to be solid or have a glove because the weight of whatever material you would pour in (to form your cast piece) would deform the mold and you would not get a proper casting. But it is funny you should ask because I am planning that for a follow on Instructable.
This seems like a tremendous amount of work, but the end result will be smashing! What a beautiful addition to the landscape! Much more interesting than paving stones or strips. <br> <br>Could you add some pictures later, when the grass starts to grow in? I would love to see it finished in the yard. <br>Thank you for such a comprehensive and inovative instructable!
Thanks Chrystalkay. It is quite a bit of work to make the mold but once it is done, making the finished pieces is very easy. I will post some pictures of the buried pavers with the grass growing in but it will be a while.
I'm looking forward to it!
This is so simple, so easy, it needs to happen more.
