This
summer we have been preparing the wood on the front of the house
(1st and 2nd floors only) for painting, but it is a slow 9-step
process as follows:
-
Scrape
off paint
-
Repair
or replace broken clapboards
-
Countersink
rusty nails and fill holes to keep new paint from peeling over
nail holes
-
Treat
clapboard and trim with bleach mixture (1 part bleach to 4 parts
water) to kill mold, if necessary
-
Sand
-
Treat
wood with linseed oil and turpentine mixture to put moisture
back in the wood.
-
Caulk
around windows with paintable caulk
-
Prime
– Because the wood has not been painted for many years, it may
be necessary to put on two coats of oil based primer. We will
use Pittsburgh Paint's Sun-Proof.
-
Paint
– 2 coats of Pittsburgh Paint's top quality Manor
Hall latex paint. Pittsburgh Paints are available locally at
A.
P. Savage Supply Company, an old
fashioned personal service hardware store, online at www.EachesHardware.com
. We were going to use oil paint, until Tucker Braddock from A.
P. Savage, arranged for Pittsburgh Paint to come out and analyze
our paint situation. Evidently, all current paint research is
focused on latex paint, making latex a much better product.

Scraping
Some areas have loose paint,
some have no paint, and others have firmly adhered paint.
The best way to remove the paint is with a good claw type
scraper and lots of elbow grease. |

1st
floor siding, protected from sun and rain, can be saved.
Siding on upper floors will probably have to be replaced.
<---------
First
the wood is stripped clean of paint and then sanded. Note
that the stripped siding almost looks new. |

| Scraping
is VERY labor intensive. There is no fast and easy way.
We've tried just about every method available ,
including a power washer ( which did little good and put grooves in
the wood). We ended up using claw type hand scrapers for flat areas,
and rounded ones for curved areas.
The
ends next to the window trim and the curved area at the bottom of
each piece are the hardest to scrape. The rounded area requires a
special rounded scraper, or the use of a drill with a round steel
paint stripper attachment. Neither method is fast.
The
old nails were not galvanized and have bled through leaving black
stains. Nails that are not covered will heat up faster than the
paint and cause the new paint to blister.
So, after the scraping is finished, all nails have to be
countersunk, the holes filled, and sanded. |
Linseed
Oil
Once the
surface is smooth and dust removed, a coat of linseed oil diluted
with mineral spirits is applied, and left to dry for several days. This stops the old wood from sucking the oil out of the new
oil primer. The area
behind the chair has been oiled while the area around the corner has
not. Notice the difference in the wood’s color.
Once
the oil dries the wood can be primed.
The above area was primed with a brush.
We
would have used the spray gun, but the last person to use it did not
clean it properly and the gun was clogged. |

Porch
Posts
The porch
needs 6 new 11 foot posts. The
cost to recreate one post is
$600, which is price prohibitive.
Instead, we will probably repair the old ones, piece together
2 from parts, and buy 4 new, similar mass made posts.
The new posts would be grouped together at the main entrance.
These will cost about $150 each plus shipping.
The old posts
were made in two parts. The
smaller piece consists of the rectangular area at the top, and a the
upper ball. The bottom portion is the round area,
the lower ball and the lower rectangle.
A large mortised joint holds the two pieces together. The bottom square area is badly damaged.
One option for reconstructing the posts involves dividing the
posts into three parts, two square ends and the center section.
The bottom square end could be easily recreated and mortised
into the round center portion. |
