I put mine up over sheetrock with construction grade glue, no nails and painted
it and it has been up for 10 years and I have never had a problem. I was going
to do only one bedroom, but I liked the look so well, and it was so easy, I did
a bathroom and a hall at the same time. I cheated, I used the tongue and grove
panel strips that are about 1/4 inch thick and made from western cedar I
believe. The finished look is the same as real tongue and groove. Good luck,
