Anybody here knowledgeable about tiling?
I have a 20'X10' indoor wall I want to tile. It's painted drywall and has a slight orange peel texture. The tiles are cement based and measure 17"x5"x1". Weight per sq ft is approximately 6.5lbs as per manufacturer. I called a Mexi-tile guy for a quote, and he basically said the whole job is "no problem". Asked is he was going to use mastic and whether that's an issue on drywall and he said "no problem". Asked if paint needed to be sanded or texture removed and he said "no, no problem". Asked if the weight of the tiles themselves would present a problem on such a large indoor wall, and again he said "no problem".
So basically I suspect a problem lol.
1) Is there any special prep needed for tiling drywall?
2) Is the wall going to risk falling down and killing me?
3) Is he supposed to use mastic? I've read that should not be used on drywall because of moisture.
