Hi - I would like to install mission style wainscoting on our walls.
I'd like to do a 60" high plate shelf, plate rail, sub rail about 9"
below the plate rail, a base board rail and vertical stiles between
the three rails. I plan to paint the wall behind, paint the rails and
stiles and install straight over the drywall, touching up with paint
at the end.
However, I'm not sure how to ensure that I don't get expansion and
contraction and therefore cracking of the paint at the joints. I
don't have a biscuit joiner or anything else to properly join the
stiles to the rails. I was hoping to find some MDF planks to use
instead, but haven't managed to do so yet. Do you think that if I
used wood, prepping it properly (keeping in room for several days,
priming and painting on all six sides) would mean that I could use
wood? Any other ideas to keep this looking good for several years?
In terms of atmosphere, if it helps, we live in Washington DC.
