Don't try to use wood paint... Ot will shine like glassy type and u r using in bedroom it should be of dim colour so use paint n vinier to get it attractive...

I have those built in furnitures in my room and the paints are chipping off after 11 years.

So i would like to renovate my room.

Do i just use wood paint to paint over it and apply a lacquer?

And how many layers of paint would be needed for the wood furnitures and walls?
