How to Apply Lime Wash to Interior Accent Brick Fireplaces
To limewash an interior brick fireplace: 1) Clean soot and grease using TSP substitute and a wire brush, 2) Dilute authentic slaked lime paint with clean water at a 1:1 ratio (for full coverage) or 1:1.5 ratio (for semi-transparent antique look), 3) Dampen the brick with a spray bottle of water so the brick doesn't absorb moisture too fast, 4) Apply limewash using a large masonry brush in circular motions, and 5) Within 10 to 60 minutes, use a spray bottle and coarse rag to wipe back high points on select bricks for an organic distressed finish.

Why Limewash Outperforms Latex Paint on Fireplaces
Limewash is made from natural slaked limestone (calcium hydroxide). It is completely non-combustible and heat-resistant, making it 100% fire-safe for hearths and fireplace surrounds. Unlike film-forming latex paint, limewash will not blister or release toxic odors when exposed to woodstove or fireplace radiant heat.
Worked Example: Standard 6×8 ft Brick Fireplace (48 sq ft)

Will limewash rub off on clothing when sitting on the hearth?
Once fully carbonated and cured (after 48 hours), authentic Italian limewash hardens into rock-solid calcium carbonate and will not rub off on dry clothes.
