Because I'm me, I didn't really measure when I sawed them in half I just went for it.
And by sawed I mean beat them up with a knife.
Not much to say about this either, it's juts as simple as it looks.
Stick it in, wait for it to dry.
I noticed I had lost two pieces somewhere hmmmmm....! Maybe the cat took it, she's been sitting inside the house a lot while I've been working on it.
I didn't have a perfect fit with it but I assumed it was because it's not supposed to be flat.
Fits like a glove, only not?
Thankfully I will cover it up with some sort of flooring since it will be a balcony anyways :)
