Painting Brick Fireplace: The Pro Process for a Modern Finish That Lasts 20+ Years

An outdated red or orange brick fireplace can drag down an entire living room, and a coat of paint is the cheapest renovation in the house — typically under $200 in materials versus $3,500-8,000 to replace with stone or stacked tile. Done right, painting brick fireplace surfaces produces a clean, modern look that holds up to 20+ years of use. Done wrong, the paint peels in two seasons and you have a worse-looking fireplace than when you started. The difference is almost entirely in the prep.

Decide on the Look First

Three approaches dominate, each with different prep, paint, and effort:

• Solid paint: Full opaque coverage. Most modern look. Best for hiding mismatched mortar or ugly red-orange brick
• Whitewash: Diluted paint thinned 50-70% with water. Lets brick texture and color show through. Cottage and farmhouse look
• German smear: White or gray mortar troweled across the brick face. Creates an Old World, slightly textured finish. More technique-intensive than paint

Once paint is on the brick, removing it is hours of grinding and chemical stripping with potential for damage. Commit to the choice. If you want reversibility, limewash (Romabio Classico Limewash, $80 per gallon) can actually be removed within 5 days of application by scrubbing with water.

Cleaning the Brick — The Step Most People Skip

Years of soot, smoke, and dust on brick prevent paint from bonding. Without thorough cleaning, no primer holds. The full prep:

1. Vacuum the entire fireplace surface with a brush attachment to remove loose dust
2. Mix 1/2 cup TSP substitute (Savogran TSP-PF, $8) per gallon of warm water. Wear gloves and eye protection
3. Scrub the brick with a stiff nylon brush, working top to bottom
4. Rinse thoroughly with clean water using a sponge — do not soak. Towel dry
5. Let the brick dry 24-48 hours before priming. Brick is porous and holds water deep
6. If soot stains remain, treat with a 50/50 white vinegar/water spray and a second scrub

For fireplaces with creosote or heavy soot deposits, a chimney sweep cleaning before painting is worth $200-300 to ensure paint adheres and to prevent staining from migrating through the new finish.

Tape Off and Mask

Use 1.5-inch FrogTape (the green Multi-Surface) to mask the firebox opening, mantel, hearth, and adjacent walls. Run plastic sheeting from the tape line down to the floor. Brick paint will splatter — protect everything within 6 feet. Drop cloths under the work area, plus a runner down the hallway from your supply staging.

If the mantel is wood, mask its underside carefully. Paint creep onto a stained wood mantel is one of the most common DIY screw-ups and is hard to fix without refinishing the whole mantel.

Prime With a Brick-Specific Primer

Standard interior primer fails on fireplace brick. The combination of porosity, residual smoke, and heat needs a high-grip primer:

• Zinsser Bulls Eye 1-2-3 ($28 per gallon): Water-based, good for low-use fireplaces. Two coats minimum
• Zinsser BIN Shellac-Based ($55 per gallon): Best stain blocker. Locks down soot and smoke odors permanently. Strong solvent smell — ventilate aggressively
• Sherwin-Williams Loxon Concrete & Masonry Primer ($55 per gallon): Designed for masonry surfaces, alkali resistant

Apply with a 3/4-inch nap roller for the brick face, and a 2-inch angled brush for mortar joints. Plan two full primer coats — one is never enough on porous brick. Let each coat dry 4 hours minimum.

Paint Selection

For the finish coat, use a high-quality acrylic latex in eggshell or satin sheen. Flat hides imperfections but is impossible to clean; semi-gloss highlights every brick irregularity. Eggshell is the goldilocks zone.

• Sherwin-Williams Emerald Interior Acrylic Latex ($82 per gallon): Premium pick. Excellent coverage, washable, low VOC
• Benjamin Moore Aura ($93 per gallon): Extremely high pigment load — covers in fewer coats. Color stays true
• Behr Marquee ($55 per gallon at Home Depot): Best value premium. One-coat coverage on most colors

Skip specialty fireplace paints unless you are painting inside the firebox. The brick face of a fireplace stays well below 200 degrees F during normal use, and standard interior latex handles that easily.

Color Choices That Age Well

White is overused but never wrong. The right white depends on your home’s tones:

• Benjamin Moore White Dove OC-17: Warm white that complements wood mantels and warm floors
• Sherwin-Williams Alabaster SW 7008: Slightly creamy, warm, classic
• Benjamin Moore Chantilly Lace OC-65: Cool clean white, modern
• Sherwin-Williams Iron Ore SW 7069: Charcoal black for moody, contemporary spaces
• Benjamin Moore Revere Pewter HC-172: Warm mid-gray, fits transitional and craftsman homes
• Farrow & Ball Pigeon No. 25: Greenish-gray, feels intentional and high-end

Sample a 12 in x 12 in patch on the brick before committing. Brick texture and surrounding colors shift how a paint reads dramatically.

Application Technique

Roll the flat brick faces with a 3/4 in nap roller — anything thinner skips over the texture and leaves bare spots. Use a 2 in angled brush to push paint into the mortar joints and around firebox edges. Two finish coats minimum, with 4-6 hours between coats.

Work in 3 ft x 3 ft sections. Roll the bricks first, then immediately brush the mortar joints in the same section, then move on. Do not let edges dry before brushing or you will see lap marks.

What to Do With the Firebox

Inside the firebox, only use stove and fireplace paint rated for high heat — Rust-Oleum High Heat ($9 per spray can) handles 1,200 degrees F. Black is the standard color and hides smoke residue. Skip painting the firebox floor where logs sit; the paint will burn off.

For non-functional or decorative fireplaces, you can paint the firebox interior with regular latex in any color. Many designers paint it the same color as the brick exterior for a seamless monochrome look.

Maintenance and Touch-Ups

Painted brick around an active wood-burning fireplace will pick up smoke staining over 5-10 years. Wash annually with a damp microfiber and Dawn solution. Plan a touch-up coat every 7-10 years on the upper portion where smoke residue concentrates. Save the original paint codes — store the empty can or photograph the label so you can match exactly when retouching.
