Richard Arfsten Farm Painting |
Here we have a story of what is necessary to paint a previously painted metal shed. Preparation in this case means removing excess chalking from the walls and tree sap from the roof. Chalking happens when the ultra-violet rays of the sun break down the paint. You can tell if it is chalky when a residue comes off when you rub it with your thumb. This residue has to come off or the new paint will peel because it does not have a sound surface to grab onto.
The two pictures in the upper right hand corner show water-blasting with 3,000 pounds of water pressure sprayed 4" from the wall. After cleaning, this roof was painted with zinc dust primer/finish coat. It is an industrial grade material used by the Navy on ships (battle ship gray). It is a very expensive coating but it's the only paint that will stop this much rust. The roof got two coats.
This job was complex because it had skylights on the side that could not get paint on them. They had to be protected somehow. It also had a piece of trim under the roof on top of the skylight that had to be painted.
The walls got two coats of red. The trim got two coats of cream.
The bushes, sidewalk, asphalt, propane tank, etc. did not get painted. All those items have to be protected — stuff to think about and deal with ahead of time.
Some paints will work and others will fail. The guy in the paint store will tell you anything to sell his materails. There is no substitute for experience. The guy in the paint store has no experience painting — he sells paint, period.
The cheapest way to do a job is to do it right the first time. That means you need a professional. I want to be your painter!
