Home Under Construction
It is
possible to take steps during the construction phase of a home that may
help insure a long lasting paint job.
If wood
siding is to be use, buy your lumber from a dealer that caries properly
seasoned, ready to prime siding.
Back-priming
is sometimes recommended as a means to
prevent dry seasoned wood from absorbing excess moisture. Back-priming is
simple applying a coat of primer or stain to the backside of the siding
prior to installation. To take it a step further butt ends of clapboards
and edges of T111 can be primed after they are cut to size during the
installation process. The idea is to seal moisture out of the clapboards.
Back priming may help to prevent future problems mainly pealing paint and
it will also help to reduce the amount of expansion and contraction of the
wood that causes paint to check. A moisture resistant exterior primer or
stain is recommended for back-priming.
Wood shingles that are to be
stained are often dipped. This process is basically done by dipping the
shingles one by one into a bucket of stain, to virtually cover most of the
entire shingle, Then tossing the shingles loosely into a pile or hanging
them on a line with clothespins to dry. Of course shingles that have not
been seasoned or still contain a lot of moisture should not be dipped. If
anyone is going to dip shingles, they should keep a watch that the
shingles do not warp too much during the drying phase; they should
probably not be placed in direct sun to dry for that reason.
Be sure all exterior nails or screws to be
used are corrosion resistant to prevent staining of the siding.
Home Design is also an important
factor involved to produce a long lasting paint job. Vapor barriers and
ventilation systems are used to control the accumulation of moisture. Even
when a paint job is done properly, a home with a moisture problem will
quite likely need to be painted more often than it should be, due to
pealing paint.
