Contractors did faulty Silicone caulking job along shower door, causing wall to be damaged by water...Wondering how to fix wall, and put tiles back on....Wall basically became a sponge....where to start?

have recaulked area, now would like to fix area that was damaged....any tips would be greatly appreciated.....

{we do live 1 mile from beach in Southern California, So i'm thinking some of the bubbling paint could be caused by moisture in the air, contractor speedy paint job in bathroom, or maybe it is all caused by faulty caulking job (basically noticed needle sized holes in silcone caulking)}


here's some pics:

this is pic of other wall next to shower it leaked there also, but not as bad, wondering if i can just sand wall down a bit and replace tiles to it?





For wall behind toilet, I imagine i have to remove toilet, cover whole in floor from toilet, not sure if i can just sand some of the bubbling paint, to smooth wall again, possibly pick bad parts of wall out and use some sort of drywall putty to get wall looking right again, or do i need to cut wall out and replace drywall?

will possibly be selling lot the house is on in near future, and moving so it doesn't have to be picture perfect new this new that.....but would like to get it looking better than it is.......thanx for any help........

 

seems this website doesn't allow links from tiny pic.com

is there some other way to post pics that work here?

 

Yeah, post them on photobucket.com and copy/paste the HTML code back to a post. We can see them directly that way.
One question/statement.....concrete backer underlayment doesn't "bubble". Is your tile installed on cbu or on sheetrock?

 

Do you have a fan in this bathroom? Bubbling paint can also result from too much moisture trapped in a bathroom during hot showers. If you notice your mirrors fogging over your fan might not be removing enough moist air.

How recent was this bath remodel? Did you see walls before the put up the tile? Did it look like plain old sheetrock?

 

there is an exaust fan in there that does a good job when left on when shower is in use, but sometimes it is not left on when shower is in use.....also when they installed the exaust fan the hose from exaust fan just goes up into the attic, i'd have to check again but need to route it better.....as it is i think it freely just shoots into the attic not attached to outside vent as it should be.......

re caulked the tub so no more leaking from where edge of tub meets/ shower door......i just can't imagine that causing all the damage, but i guess the drywall/backer board may have soaked it up.......
Also read that if the surface a person is about to paint isn't cleaned properly, the paint can bubble after repainting.....not sure the exact problem, but thanx for the help


thanx for the photobucket link

 

Others may chime in differently, but that appears to be plaster walls, am I correct? If so, it will require not only a removal of the paint, but a substantial plaster repair, priming and repainting. It also looks like oil based paint with no primer, so that may have been done in error. Give it a little time and you will get some good advice.

 

between the toilet and shower is that backer board mixed with plaster?

 

I agree with Chandler - it looks like plaster.

It is hard to say if the paint is oil base or latex, there is a sticky at the top of the painting forum with instructions on how to tell which.

Obviously you will need to remove all the loose paint and plaster. Hopefully the brown coat will stay more or less intact. Unless you have plaster skills, you should use a setting compound like durabond to make the repairs. Durabond is a bear to sand so it is best to use ready mix joint compound for the last coat. You can use j/c for all the repairs but it might crack if applied to thick.

 

the rest of the house has drywall, I believe , how can i tell if its plaster, whats the difference?

 

once i get i get all the loose stuff out, it can be patched and sanded?

someone else told me i should cut the wall/ drywall out and replace it, for mold purposes...with green board

 

Plaster is applied over some type of lath. The brown coat is applied first. If the brown coat is in decent shape, it is usually best to repair it. If you need to replace a section of plaster with drywall, you can. You may need to shim the drywall a little so it can be just shy of flush with the rest of the walls.

Personally I would't use greenboard. It doesn't always paint as well as regular drywall, plus once painted with a latex enamel - moisture shouldn't hurt it.
