>>2I want to replace water-damaged celing of my basment which is made of sheetrock with plywood of 5 plys of the same thickness and with one side sanded and finished so I can paint it white.
The unfinished side I wish to shellac and also where the water damage on the sheetrock is I wish to drill a hole for water drainiage.
I don't really like sheetrock because if it gets wet it gets destroyed, also it's weak and can be punched through.
The basement celing is like 7 feet up.
This sheetrock is under the 1st story bathroom and gets water sometimes.
Not always, but sometimes.
You know how it is.
What do you reccomend?
The sheetrock is of standard thickness (1/2? 3/4) so for 5 ply I will need the plys to be thinner than the standard bottom-grade plywood.
I want lots of plys because since the celing is kinda low, it might be 7 or 8 feet: one has the "desire" to puch the celing when drinking and listening to music.
I want it to be unbreakable.
Also I am thinking of putting fiberglass pink insulation in said ceiling to keep some sound from going to the 1st floor. But not near the bathroom (as there is sometimes water)
