Limestone front and chimney on a 1980s ranch house
Example project

- Home
- 1980s single-story house with a live oak in the front yard
- Original request
- Even out patchy cream limestone without painting it
- Surface
- Chopped limestone on the front walls and the chimney
- Area
- About 500 sq ft of stone
- Existing finish
- Bare limestone, dusty, with some darker weathered pieces
- Finish
- White limewash, a thinned first coat and one fuller coat
- Timeline
- Four working days, coats brushed only while the wall is in shade
- Estimated cost
- $3,200
Scope of work
Washing the stone with a garden hose and soft brushes; a water test on several stones; protection of the windows, frames, trim and shrubs; dampening before each coat; a thinned first coat and a fuller second coat worked into the joints; ladder work on the tall chimney; rinsing glass and frames at the end.
Project overview
In this example, the front of the house is chopped cream limestone, but years of sun and rain have left some pieces darker than others, so the wall looks patchy from the street. The owners want it calmer and lighter while it still reads as stone, which rules out masonry paint.
Raw limestone usually soaks up limewash well, so the first coat is thinned to pull the colors together, and the second goes on fuller only where pieces still stand out. The front gets the afternoon sun, so every coat is brushed in the morning while that wall is still in shade.
The goal
The goal is a calm white front where each chopped stone keeps its shape and shadow, and the chimney matches the wall instead of standing out.
Process
- Two weeks before Water drops on several stones to check they absorb, and a thin and a full sample brushed low on the chimney.
- Day one Stone washed down, windows, frames and shrubs covered, and the wall left to dry.
- Day two Wall dampened in the early morning and the thinned first coat brushed on before the sun reaches it.
- Day three Fuller second coat on the darker pieces, then the chimney from ladders, again in the morning.
- Day four Covers off, glass and frames rinsed, and a look in late light, when the joints show any missed spots.
Planning right
- Stone in full sun gets far hotter than the air. We coat each wall while it is in shade, not only on cooler days.
- If water beads on a stone instead of soaking in, it has been sealed or is too dense, and limewash will not bond there without more preparation.
- Turn off sprinklers that reach the wall until the limewash has had the dry period its maker asks for.
- Exterior limewash thins slowly over the years. A new coat later goes straight on, with no stripping.
