Doing ceramic backsplash in the kitchen. I've done plenty of tile on painted drywall, but I'm from up North, where the walls are smooth. Here in Texas it seems every house has this terrible knock-down texture on the walls. Anyway, I'm worried that the texture might somehow detach, causing a tile to break loose. I plan to use adhesive with a v-grooved trowel. 6 x 6 tiles with 3/16 spacers.

Anyone have experience doing this? Will my tiles fall off? Thanks.
