How to fix water damage under my sink?

Question

You know the kind, the cabinet gets all warped and the lining is raggy from some mishap like the dishwasher drain hose disconnecting from the drain pipe.
It's how it was when I moved in. It's dry, no mold, just annoying for me because I want to make the house as "perfect" as possible and the warping makes some of the things I store under there tip over. Clutter-y
Any ideas to fix this?
Is there a way to fix it so if there's another mishap it doesn't warp my cabinet?

Answer 1

I figure : The cabinet is made out of particle board(which swells when it gets wet(and basically falls apart)
The only thing you can do is cut out the rot(warp,swollen)board and replace with a piece of plywood(which you paint with an oil based paint first on both sides and let it dry a day or 2 in the sun before putting it in as a patch.)Make it so that this "patch" slopes to the front - so if a leak should happen, the water will just not sit there, but will run out the door onto the floor.(It will anyways once there is enough water, but why have any sitting there when it does not need to?)
You could even use particle board again(so long as you use OIL based paint and prime it on all sides)
Then after you have the new piece nailed in, silicone the gaps if there are any. Wait a day and another coat of oil based paint(finish coat stuff - not primer over the top) and the walls of the cabinet as well.

Answer 2

Figure gave good advice. I would leave the old alone. You can build a platform to sit on top of the warped one. I would use water based paint (when dry it forms a latex rubber seal)

Answer 3

I so relate to this Q. I'm redoing the interiors of kichen (under the sink) and bathroom, NOW.

I measured the space, checked to see if the plumbing, even with collars moved up and down at a valid distance, tore out the old warped, damaged base shelving, cut new from 3/4 ply, even the plumbing cutouts, added new 2 x framing on the floor, set the ply in place, and then I covered mine with a rubberized, easy to clean, sheeting (Ballet Dance floor material)...I'm happy with the result.
