Liquid nails,builders choice,490 construstion adhesive. J.

i am planning to remove my old deck boards (which I plan to use in my pasture) and put down treated 3/4" plywood. I've been told i can put ceramic tile on that and grout it in, but i'm not sure so I plan to put backer board on top of the plywood and then lay the tile and seal the grout. Should I use regular thinset or construction adhesive to adhere the tile? Should I use grout with or without sand? How much grout space should I leave? This is an uncovered outside deck. Will this hold up outside?

thanks all. --probably thought I'd gone away, taking so long to answer. It just seems one "challenge" follows another. The time goes by and you try to hold things together or repair things including your body and sometimes, things just keep coming. Hopefully, I'm forgive for being long time in answering. It's been in & out of docs. for me and tonight, wife goes to hospital. I managed to get a small, very small, strip piece of the paneling off, intact. I used a blow dryer to heat it. The adhesive cement is very, very strong. the blow dryer took a long time to heat the wood--I thought it was going to scorch , before the paneling came loose, but I finally got it. That 4"x4' section took over an hour of work! There does seem to be though a magic temperature, if I can get up to it, the adhesive softens enough to let me hammer a putty knife between it and the wood, other wise--no go. the putty knife won't cut it and the piano wire I tried to use, broke. I hoped that was the piece that would give me access to what I needed to work on, but no. I'll have to remove at least, maybe two, of the full 4x8 sheets. If I destroy this Walnut, there will be no way to replace it. And I do not want to have to figure out some other way to refinish the basement--I guess I could glue sheet rock to the walls, if I glue enough shims in first. I just hope I can get the panels down. You'd think that 30+ year old glue after being so old and going through freezes and thaws would be brittle and give way, but it sure doesn't. Probably the easiest way is to pry the furring strips from the walls and try to put them back up? Because of the unevenness of the concrete walls the strips are glued on both horizontal and vertical. And to get them off, I'll have to take down the entire wall! -- ouch! Is that the only way? I did such a great job putting this stuff up, I can't even see the finishing nails I used to make certain the panels stayed attached to the strips while the glue set. Then of course, I dabbed a bit of paint, the same color of the dark, vertical seams they are in, on the nail head. they are virtually invisible. To find them, I hope a magnet will work. If I pull off the furring strips, they won't be a problem. If I try to take off the paneling, I'm not certain if I have enough room to drive them through the panels before they hit the concrete. What a job. In removing the one little piece of paneling, I learned that I'm going to have to pull an entire corner of the ceiling tile down, as well. It just gets worse and worse...or maybe I should look at it as an exciting challenge? Let's see if I can do it? --yeah, right :( Instead of using a hair-dryer to try to heat the wood, what about trying an electric iron? Think I could do that without scorching the paneling? If so, how high of heat would you set it to and what would be good to put between the bottom of the hot iron and the paneling? --I don't think laying an iron, directly on the walnut, would be very good for it. Or should I just give up and try to separate the furring strips from the wall, leaving the paneling attached. --What a nightmare it was putting those up--absolutely nothing was plumb, level. It took hours and hours to get them level and plumb. Maybe there's an expert way to get these down--it'll take at least 4 people to take a wall all in one piece, especially to not cause damage to any of the panels. Then, how do I get it back up? Is it time to throw the walnut away and put up sheet rock? Bob

I would suggest just nailing your trim. While construction adhesive works, it makes it a lot harder for the next guy if the moulding needs to be replaced. For that piece on the curved wall, make what are called "kerf cuts" across the back of the moulding. They're parallel cuts made with a saw placed about 1/4" to 3/8" apart. Obviously you want to be careful not to damage the finished side of the moulding. Those will allow the moulding to bend. While not the best picture, should give you some idea what I'm talking about:
