Casting foundation for stove, moisten during curing time?

[ekblom]

Hello!

I'm in the process of casting a foundation for an upcoming cast iron stove. Since it's indoors and around 20 degrees, it might dry too quickly? Should I water it? Cover it with plastic? Any other ritual?

Very grateful for any input that can be received a little late like this.

Best regards,
Ekblom

What are you casting with?

Cover with plastic.
It's not a casting that requires full strength that you're doing, so even if it cracks, it doesn't matter.

just as mentioned above, a plastic is sufficient, and a small crack is not the end of the world

As I suspected, said and done, glapack it was...

Thanks for the consultation!

When I last cast, I placed a damp/wet rag rug on top and that worked too, I would have probably put over something similar. Maybe an old bath towel?

How long should I wait before removing the form? It has set now anyway.

After a couple of days, I usually remove molds, not immediately as the concrete is quite soft, not after a couple of weeks as it's harder, but the concrete is hard.
Say 2 days, if you cannot remove the mold without affecting the casting.
