I am going to make some routed signs. Just lettering and arrows for
directional signs. I think I will use redwood. The routing will be about
1/4" deep and 3/8" wide.
I would like to just lay the board down and pour some paint in the grooves
and let it dry. I have seen some like this, and they look good. Would that
be okay, or should I just paint the routing with an artist's brush? If I do
pour paint, what type would last the longest?
Paint the grooves any way you like, then sand the paint off the top.
Or put some kind of film on the top (like spray-mount paper, wax, or
shellac) before routing (perhaps the pattern for the routing?), then
spray paint, then peel off the film (or sand, for shellac or wax,
assuming the paint doesn't just peel off it).
If it were me, I'd be using a paper template anyway, for the routing,
and I'd tack it on with a light spray adhesive. After routing, I'd
spray, then peel off the template, then sand the top to clean up the
For poured paint, why not tinted epoxy?
I've done a little playing around with signs after coming into some
reclaimed redwood, and I really like the look of routing the
background rather than the letters, then painting the raised letters.
Easier to paint, too.
For what it's worth, if you're going to let the redwood weather
naturally, it's not a bad idea to use a solid stain rather than paint-
that way it simply fades over time, instead of peeling and blistering.
Makes touch-up a whole lot easier. The only trick to it is keeping
the stain back a little way (maybe 1/16") from the edge, so it doesn't
bleed along the grain on the face of the sign.
