The PW Asks: How do you prepare for a day of exterior home painting in freezing temps?
The Painter Says: In freezing temps you can only use a semi-transparent product or an oil product and you must add isopropanol to the product which is gas line anti-freeze. There is water based colorant, even in oil based paint. This tiny amount of water helps suspend the colorant. In freezing temperatures, this moisture will crystallize unless the isopropanol is added. Next, the paint pump must stay indoors so the product does not freeze while the hose is snaked out the window.
PW: Why would anyone paint a house at below freezing temps?
Painter: Because the builder of the home may not want the bank to hold money in escrow. If the exterior is not painted by the time of closing, money will be held back.
PW: What do you wear to prepare for this kind of arctic feat?
Painter: A union suit, insulated gloves and good boots.
PW: Brrrrrr
