On an exterior painting project, rusty nails are a problem. When nails begin to rust on an old house, it causes a rust stain to appear on the surface of the paint. Eventually, the rust will cause the paint film to fail and flake off.

Dealing with Rusty Nails Before Exterior Painting

We are currently doing paint restoration on a 1882 farm house. There are a total of 3,600 rusty nails on the siding of this house. As a first step in the preparation work for this exterior painting project, we had to set up a procedure for effectively dealing with the rusty nail situation.

As a first step, our house painters used a nail punch slightly smaller than the nail heads to sink the nails by no more than 1/8”. We then scraped the loose paint off the face of the nails and applied a rust converter to kill off any rust residue. Our painters then filled the nail holes using a waterborne window putty. We chose this product because of its rust-inhibitive qualities and also because it requires no sanding and no priming, and has a quick curing time. Because this product shrinks, we had to hit the nail holes two or three times to eliminate any cratering of the product.

Our client greatly values his piece of Northern Illinois country history and he wanted to make sure his rusty nail issue was permanently dealt with before we undertook the exterior painting of his old farm house.

By creating a flexible seal for the gaps in the external components of a building, caulk keeps water out of the structure. Unlike paint, caulk has the ability to expand and shrink with the ambient temperature and humidity. When caulk begins to fail, moisture gets into the surrounding wood joints. Before long, the moistures causes paint failure, eventually rots the wood and causes expensive repairs on the outside components or even in the interior spaces.

Because of our frequent freeze and thaw cycles, caulk often begins to fail within 2 or 3 years, even though “45-year” or “55-year” caulk may have been used during the exterior painting project. It is therefore important to do maintenance caulking and maintenance painting.

A visual inspection of the surfaces every three years at the most will reveal areas where caulk has begun to fail. Intervening at this stage to remove the failing caulk, re-caulk and spot-paint those areas will add years to the life cycle of a exterior paint job and prevent expensive repairs.

Make it a point to ask Painting in Partnership to come and inspect the caulk on your house. This is work that saves you money!

Exterior painting in Chicago? Sure! However, exterior painting in the North Pole does not seem to be a likely prospect and neither does a color design consultation to develop a color scheme for an entire town of 1,400 inhabitants. Yet, both happened in a coal mining town called Longyearbyen in Norway, the most northern town on earth.

What makes it an unlikely scenario is that, in a climate this cold and dry, wood does not rot. Therefore, there is no need to use exterior painting as a means to preserve wooden structures, which is a nightmare scenario if you are a house painting contractor in the area. Consequently, without the colors that paint would have added to the décor of the town, the predominant colors, for most of the year, were black, white and every shade of gray.

Another critical factor was the wildly varying amount of light through the year, from total darkness for 3 months to twenty four hours of sun in the few summer months. The rest of the time, there are blue shadows and a sky that changes from pink, to turquoise to lilac.

Most of the town’s buildings are owned by a coal mining company. In 1981, in a bold and visionary move, the Board of Directors of the coal company hired Grete Smedal, a renowned environmental designer and color expert, to develop a color scheme for both housing and public buildings in the town. Having understood the power of color to enrich one’s environment, the Board presented Ms. Smedal with the challenge and the opportunity of a lifetime.

In 2004, I had the great pleasure and privilege to meet Grete in Trumso, Norway, at an international conference of painting contractors. After the conference , she sent me a copy of the book she had written on this unique color design and painting project.

After much study and deliberation, Grete finally settled on a color palette of almost equal whiteness, blackness and chromatic intensity. All the colors were of medium lightness, which allowed the color scheme to offer sufficient contrast in any season.

The actual exterior painting was executed in the 80s and 90s, which brought a smile to the local painting contractors. Ms. Smedal gave the school building a special color treatment. She had a row of 50+ windows painted in the colors of the rainbow. In her book, published in 2001, entitled “Longyearbyen in colors – status and challenges”, she quoted an anonymous miner who wrote the following:

“A span of the rainbow over summer wet meadow,
Is it a dream of a time you have left?
Much is forgotten, but may be not this:
The hunt in the woods for the rainbow’s end.

Just before the darkness of fall shadows the sun
You see a vision and then you see that
The end of the rainbow has hit on the school.
The treasure of Knowledge is the happiness you sought.”

Thanks Grete Smedal for your magical work in the North pole!

Color and painting have the power to add great value to people’s life. This is the belief that inspires everything we do at Painting in Partnership, Inc., painting contractors in the Chicago area.
