Installing tile..background questions ?

[Jackster]

Purchased a Exo-Terra 36x18x12 terrarium. I am going to use tile as a substrate and I will have to trim the 6x6 tile to fit.

Home Depot said that they did not offer that service. How do you trim the tile?

Also, I will need to trim the polystyrene background after installing the tile.

What is the best​ way to trim/cut the polystyrene? Electric turkey carving knife or some other way?

You can trim it using a grinder with a cutoff wheel, but it's going to create a LOT of dust. Ask me how I know this, LOL. Or, you could cruise around the local pawn shops and pick up a cheap wet tile saw like my dad did. Then when you're finished, sell it on craigslist or something.

As for cutting the polystyrene, that's going to be a crapshoot. I cut mine with a razor knife, but it came out a bit odd.
