putty leaking from plywood ceiling
hi, I'm installing a new plywood ceiling. the decorator has tried to seal and paint the gaps between the boards several times, the next day the putty has leaked down to form ridges all around the ceiling. any suggestions?
Started with regular household putty, that leaked down and formed the ridges, yesterday he tried car body filler. This has dried and separated from the wood.

Welcome to the forums.
Let's start at the beginning: why are you putting up plywood instead of drywall?

Exactly what do you mean by 'regular household putty'?
Normally it's best to nail up a strip of wood to cover the gaps between sheets of plywood. Filler's can be problematic when used with plywood. Putty that sagged, did so because it was applied too heavy.

Putty is often used to incorrectly refer to glazing compound. A substance that can stay pliable for sometime. Putty often refers to plumbers putty. A substance that doesn't fully harden for a long time. There is wood putty which generally doesn't dry and is used for nail holes and such and wood filler which does dry. What are you calling putty?

I've also heard some here in the south call j/c - drywall putty 
Glazing compound and painter's putty are very similar although while you can putty nail holes with glazing, you can't [or shouldn't] glaze window sash with painter's putty.
Knowing why plywood is being used for a ceiling should help us understand better what needs to be done.
