Juliagoolia Posted June 18, 2020 Report Share Posted June 18, 2020 Does anyone else's drying plaster get a weird furry powdery thing happening the day after reclaim drying? I inherited this from the woman who sold me essentially her entire studio. It just brushes off, but it will cover substantial amounts of the plaster. Thanks in advance potter friends.
