What is "lime washing" wood?

Lime washing wood is applying lime to wood in a thin coat to create a chalky white appearance. The lime is both decorative and protective, penetrating deep into the wood's pores to provide a peel-free, breathable surface.

The chalky appearance results from the lime reacting with carbon dioxide in the air in a process called carbonation. Carbonation returns the lime to its prior limestone state, expanding the crystals to adhere to the wood's surface.

Lime washing should be done when temperatures are above 41 degrees Fahrenheit. The lime should be allowed to dry slowly, and the surface should be misted with water if temperatures are above 86 degrees Fahrenheit during application.
