Chris, can you then paint it with latex primer, or do you have to
use oil base?
Don Craig
use oil base?

I had a pirogue for many years (see other discussion) that was
painted with oil based paint (I think) and it checked like crazy with
little fine cracks every 1/4" or so. This happened pretty early on
in its lifespan and there was never any rot. This was in the intense
heat and humidity of South Louisiana. The boat was stored both
outside and inside over the years.

A great way to minimize checking in fir is to use linseed oil. After
you're all glued up, but before painting, a complete flooding of linseed
oil (unboiled first, followed by boiled), will minimize checking *a lot*.
The oil will interfere with epoxy and other glues, so use it post glue.
You can then prime and paint it just fine. It's worked for me.

Just sand smooth and repaint. If the cracks are large, you can use filler
such as Bondo or good wood filler to smooth things out.
It'll be an annual event usually.

Sand, fill and paint again. Don't lose sleep over it, annual maintenance
should keep things in order. Our fir plywood Blue Jay lasted for years with
no more than its annual painting. It checked, but the paint filled the
cracks and we never had any rot. It spent the summers in fresh water, and
the winters upside down under the snow.

> Well what is checking ?Cracks, large and small that open up in the surface of the wood. Usually
caused by the different rates of expansion / contraction from the different
wood densities found in many plywood products, especially Fir and Pine.
Plywood is rotary cut from the tree using a blade to shave a thin veneer off
the tree trunk. Some woods have different densities of wood fibers from the
center to the outside of the trunk, even around the branch locations. When
all is glued up into a panel there is no real way to match densities. Hence
as the sun and temperature change each layer and/or density will want to
expand at different rates and direction. It's a very strong pressure which
cracks the epoxy easily.
Glass is very strong with epoxy if strong and stops this expansion on the
surface anyway not allowing the cracks to develop.
