primer for humid bathroom? tile over top?


You shouldn't have mudded. I would remove it. Use tile adhesive in the joints. Did you tape the joints? That would make it easier to remove.

Dens-shield is approved for wet areas where greenboard isn't. You can safely tile the ceiling too. Smoothing it will probably be a waste of time. Either replace it with a paintable surface, paint it the way it is, or tile it. Tile will give you the most bang for the buck and you won't have to do extra work, which is what you tried to avoid by buying dens-shield instead of cement board.

If you'll wet the drywall mud that was used on the Denshield it will easily scrape off which is what must be done. A wet spnge can then be used to clean off any remaining residue. Then the joints can be filled covered with alkali resistant seam tape and filled with thinset mortar.

Any Denshield/drywall joint that may exist well beyond the tile termination can be finished as you have done already with drywall compound if you are going to paint it.

I would also suggest tiling the ceiling at this point. This way you won't have to deal with the texture of the Denshield.

primer for humid bathroom? tile over top?


Holy expletive word that starts with an f ....tile guy, am I glad I checked in here. So that was a fairly stupid idea to mud this area or what? Why, exactly is the mud no good? Does it hold water and then slowly rot denshield board or worse yet mold? I just need to know? I did tape joints, not that it matters anymore. I thought tiling the ceiling would be so cool, but I don't have any idea how to hold the tiles up there until the tile adhesive dries. I was planning on using a product called omni grip for the wall tile and I purchased a bag of versa bond fortified thin set mortar for the floor. Originally was told that I could use omni grip for both the wall and floor but on a return visit to the same store a different guy told me that omnigrip on the floor is a no-no among pro tile guys. What do you say? I have a very large pail of omnigrip now and that shtuff is expensive, I think eighty dollars, not opened yet. either one. What does 2 set mean? it says that on packaging of both these products? What is alkali tape? I think I used a fiberglass mesh tape flexible and sticky but I could be wrong on this but will find more specifics on that when I can. Thank you so much for all this info guys I really appreciate this help. One day soon I will get a camera and send pics. I will definately tile the ceiling when I find out how. The tile will flow right out the tub area but drop down to half the wall about six inches outside the tub as that is where the densheild line ends and the green board begins so that would probably not fit your description of "well beyond the tile termination point" will it. This detail I cannot fix, I am not ripping that out and not buying more dens sheild, but would like to find the best possible compromise for this dens sheild to green board merger, someone suggested a skin coat of something earlier. I will remove the mud from the tub surround area though for sure, (i hope it comes off). What is this red guard stuff all about? Would that stuff help me at all? Thinset would not seal the mud would it? not second guessing but I did not want to make a mess of the dens sheild coating by sanding paper it off. Someone should make water proof drywall mud clearly marked or tell the guys at home depot not to recomend the method I used. what a pain, I can now relate to the devil analogy of these guys but I guess i should share the blame somewhat because I did not listen to my gutt feeling until after I applied it. I figured a large store like this would have well trained people to offer solutions so I took their word. I should have signed in here earlier. I think there is no experience that compares with actually getting your hands dirty with some of these fine arts not to mention the importance our forefathers of the trades that pass this experience down the line, very awesome! This job will not be inspected but I want it to last and be safe. Thanks Again.

Mac,

Bud hasn't been back to answer, but I talked to him in pm earlier. No, it's not the same as fiberglass mesh tape. It's alkalai resistant.

I must extend my apologies for my last post, as I got caught in the excitement of the fact I checked here before wasting my efforts, anyways, sorry if I offended anyone. We have removed the drywall mud from the dens-sheild as you have vehimately suggested. I must admit that I almost said to heck with it and left it the way it was, but then why would I have asked? I thought that it would be to much of a risk to damage the dens sheild removing drywall mud rather than procede and hope for the best.
However, I tried the tape edges and they pulled off quite nicely, as well, the water and sponge worked great and I did not have to put much water to it at all like I had feared. I am happy I listened.
So now I have a clean slate to work with and also piece of mind this job will be as correct as possible.
I went to give someone at home depot a hard time for this but, they played dumb like "oh we would not have told you that"
I did mange to get a copy of the revised instruction paper that is stuck to the back of each dens sheild board. It says to use woven fiberglass tape and embed with tile bonding material. It also goes on to say that if you have cut outs of any kind to use an elastomeric caulk, flexible sealant or tile setting material to prevent penetration of moisture.
SO I will use a kitchen a bath caulk, 100% silicone that is mildew resistant and permanently flexible. Would this be O.K to use on all the joints?, I did not dig the drywall mud out of the cracks so I am thinking the silicone would definately work well to seal the board with the fiberglass tape? only wondering what the omnigrip will do as far as bonding to silicone? I thought that silicone was very slippery in nature and might not be a good substrate for omni grip to adhere to, but it also seems to me that omnigrip is kind of like a synthetic mortar, so maybe would work well together? I would not need to use much silicon, maybe just enough to hold the tape in place until tile is set.
I have surfed around to find some info out for the omni grip tile adhesive. I found a similar story to mine for a couple that on the advice of home depot workers told them to use this product to lay floor tile. They went with the advice and sounds like had to redo their floor at extra cost to them. Home Depot played dumb with them and only offered to refund the cost of the omni grip but thats about it.
I was fortunate enough to get a second opinion from another home depot employee on another visit, I am not sure how he knew not to use this stuff on the floor and the first guy did'nt,but, he did mention that he had heard the professional floor tile guys would not warranty work done on floors with omni grip. I sure hope it works on my walls and celing.
By the way I was wondering how to do tile on a ceiling? Thank You

It says to use the caulk on cutouts, not joints. Just use the tile embedding material to bed the tape down. And in the cracks. I wouldn't use silicone anywhere other than cutouts.

I'm just a painter, so I have no advice on omni-grip, but I sure would talk to someone at a tile store or someone who would know for sure.

I'm glad you took your time, re-read the posts and followed up on information.

People ask, we tell them, and they don't like the answers, that's where the headaches start.

Good luck. Sorry, I can't give advice on tiling the ceiling, but I'm sure if you dig, you'll find the answer.
Yours
