We have just painted the bathroom using silk finish paint but it is not adhering and in some areas can be wiped off (1 day later). We wonder if the paint underneath is bathroom paint. Can we wash the walls and start again – if so what should we use?

My house painters (hired by my carpentry contractor) are painting the aluminum siding on my house (Sherwin-Williams acrylic primer/paint). We’ve had more rainy days than dry days. After rain, I wish they would allow one sunny day to dry things out before continuing…but…they always show up to paint the day
