I am beginning a project for an outdoor kitchen. I want to use tile, but
mostly in a vertical position for decoration. The substrate would get
occasionally wet, but not a lot. Maybe not at all if the roof covers
everything, and doesn't leak or drip any water.
What do I use to hold the tile onto the substrate? Do I use plywood or
concrete board? Grout it? Liquid nail it and fill in the grout lines? A
particular mix of grout?
I will be doing whole pieces of tile of all sizes, but may also nibble some
pieces down to make a mosaic effect in some fields. So, the pieces would
have to be put on in a horizontal position, then the whole board put up
vertically. Or put on and held in vertical position.
Perhaps the exact same grout/adhesive materials and installation
procedures as what goes on when tiling any household shower, which
actually gets drenched by gallons of water daily and gets tiled while
That'd be my idea, methinks.
To answer some of your questions: Concrete board (Wonderboard), thinset
mortar with latex additive, no Liquid Nails, use masking tape from one row
to the next higher to keep it from sagging, 4.25" self-spacing tiles with
little nubs on the edges, grout is applied days later when the mortar has
dried. Home Depot sells a good book called "Tiling 1-2-3" which makes it
all deceptively simple. --Bill
I think I would use a concrete board substrate. However, you could instead
use expanded mesh and concrete to create a mud bed (see professional brick
and mortar supplier for explanation of this). It is a LOT simpler for a
DIY'er to use concrete board.
I would use Versabond or something similar for adhesive. It is a
concretious latex-added thinset mortar. There are no problems using this on
a vertical wall. You can nail a temporary batter board up with just a few
finish nails to support the first course of tile. Then just lay tile just
the same way you would on a floor. It will not fall if your mix is good
(stiff cake frosting) and you set the tiles properly. After the appropriate
setting time (is it 72 hrs?), you can grout, then after letting the grout
set (is it a week?) you can seal the grout. Whether to use sanded or
unsanded grout is based on how wide your grout lines will be. It is not all
that difficult, and a decent tile shop will give you all the advice you need
to get you through.
