First, read the English article below.

Paints that you would use on the styrofoam, like acrylic, dry very quickly and should be ready for a second coat after roughly 10 minutes. Styrofoam is very porous, so check the styrofoam after the paint dries to see if it needs another layer of paint to cover up any white specks. Use your finger to touch the styrofoam to see if the paint is still wet. 

Now, please write a short abstract for it in Indonesian. Abstract:
Tunggu 10-20 menit sampai cat kering.
