Great Stuff Foam Question

[Medgrik]

I just used some great stuff foam for my terrarium..I used it outside but my question now is can i let it dry inside the house for 24 hours?.. i don't want it sitting in the freezing cold tonight. Thanks guys!

Of course, it dries no matter what. Poke holes in the deep parts so it dries correctly. I used it a lot in my last build :P

Sorry i meant in terms of releasing toxic chemicals into the air.. if it infact does that.. i dont have much ventilation in my place.

Nope, nothing that could harm you..if you stick your head in and breath deep maybe, but other than that you're fine.

When I did my build, I put all my great stuff foam in the tank inside my house with no issues.

I do all my GS foam work inside my living room or Kitchen. The smelly work is with the silicone but GE II isn't too bad and the smell goes away pretty quickly.

Can i use acrylic paint right on great stuff?.. it's gonna be under the water. Will it wash away quick if i can paint it right on?

My experience with Great Stuff Foam is it might expand and contract just a tiny bit. In my builds using mortar mix painted on the surface the mortar will crack vs ridged foam. Acrylic paint is safe to use but whether it will stay in place I just can't answer. If its covered in silicone and peat fibers then it will remain flexible and you should have no issues.

For underwater use as long as acrylic paint is dry it should not wash away. I have used acrylic paint on the rock work for my water falls with no issues.
