Hello,

Live outside of Boston.

Had new Cedar siding, pre-primed (oil) from the siding mfg., put up.

The pre-prime that they applied looks very uniform, clean, and "good".

There have been suggestions by others, and also by one or two painting
contractors, that another coat of primer should be applied prior to the
regular Latex house paint. Some said though, that it is really not
necessary
to prime again.

If I do go with another priming (to help prevent bleed thru, adhesion,
etc.)
the Contractor said he could tint the primer somewhat. Color, to match
the
rest of the house, would be a medium brown.

Cost is becoming a factor.

Question:

Would another, Tinted, primer plus a Single coat of Latex-

- last as long as two regular coats of latex right on the existing
pre-primed siding ? (my original thought regarding the job)

- would it tend to "look as good" and last as long ?

**Or, would it really be necessary to have the conventional two coats of
Latex paint, still, put on over the extra primer coat ?

Guess I'm asking about the desirability of the additional primer coat and
only one coat of regular paint ?


The only reasons to reprime (for the purpose of priming) are when the siding
has been sitting around for a long time without paint or when the primer
coat has been damaged to the degree that bare wood is showing, which would
warrant spot-priming.

Some colors, like red, can sometimes require up to seven coats if the primer
isn't tinted (dark gray primer works better than red primer). Coverage
depends on the paint formulation and the sheen. Sometimes it's wise to
reprime with tinted primer to get better coverage because primer is cheaper
than paint, but usually only with certain reds or greens. I used red
O'Leary exterior semi-gloss paint the other day and it covered over white in
two coats.

Extra primer is worthless with regard to the long-term protection of your
siding. You should definitely go with two coats of paint or solid-color
stain, even if it covers in one coat. If you were repainting, one coat
might be an option, but you're not. Protect your investment.
