**REMEMBER when fast-drying plaster molds be sure to stand them upright, so that it is standing on the smallest surface area. I imagine rigging some sort of fan-and-heat combo would do the trick alright as well. Heat it good, but you need ventilation to carry the moister away from the plaster. The one we have is pretty shoddy at the moment because it doesn't get too warm, but the ventilation is good. The thirds, which I have found most helpful is using a dry/hot box.

Set the kiln to hold at around 115*F and keep the lid propped. I recommend putting them in front of a brick wall (or some other dark surface) facing the sun because it makes for a toasty atmosphere. Obviously it's not great on a humid day, but if it's a hot, sunny day it can definitely make some progress. Then was taught three methods of speeding up the process.

After you learn how to paint a mural for the first time, you'll have a better understanding of the brush sizes you'll need in the future.I've been working with molds non-stop for about two months now at UF.

You can purchase an even wider brush, such as a 4", if you have a lot of space you want to fill in quickly with a single color. For covering large areas with paint, pick up some wide brushes.
The sizes you'll need largely depend on the amount of detail you'll be painting. You'll need a variety of paintbrushes, from small to wide.
