Is it safe to paint inside a fireplace? 

Painting the inside of your fireplace is not only done for aesthetic purposes but also as a layer of protection. However, it is safe to only use the standard paint for the inside of your fireplace.

This part of the fireplace where you build a fire is known as the fireplace box or firebox. Unlike the exterior of your fireplace, indoor heat-resistant paint is suitable for your firebox as it can withstand high temperatures.

A painted firebox has additional protection from chipping or rusting. It can maintain its durability during and after using it. It also hides the imperfections such as cracks and stains on its surface that build up. They are commonly caused by the formation of soot, creosote aging, movement, and maintenance issues. 

As part of maintenance, you can also re-paint your firebox at least every three years to keep it in good condition.

Does heat-resistant paint come in colors?

Like any other paint, different colors of heat-resistant paint are easily available. You can choose from dark, bold colors, cool neutrals to bright colors. It also comes in flat, matte, semi-gloss, and gloss.

You can identify the color and finish of your paint depending on your preference and style. However, you must try using a sample paint or swatch and matching it first with the design of your wall for a cohesive look.

A black fireplace is bold, classic, and elegant. It highlights the flames while using it. It also gives you a warm, well-lit room yet relaxing ambiance when you are spending time alone or having indoor activities with family and friends. 

For a do-it-yourself painting of your firebox, here are six easy to follow steps:

1. Cool Down the Fireplace

Cool the fire for several hours before starting the project for safety reasons. 

2. Collect Materials

Prepare all the materials to save time. Nothing will be missed out, and you'll have no unnecessary interruptions. Below are the basic materials you will need: 

  •  Flat black high-heat paint
  •  Primer (if needed)
  •  Paint rollers and paint tray (if you opt for brush-on) and a small paintbrush
  •  Cleaning materials like old cloth, vacuum, fireplace shovel, and broom
  •  Personal Protective Equipment (PPE) such as masks, goggles, and gloves
  •  Carton boxes or newspaper sheets
  •  Steel wool or sandpaper (at least 200 grit)

Please note that you may list other materials depending on your need and type of fireplace.

3. Wear PPEs & Cover the Work Area

For your protection, personal protective equipment is essential for any DIY project. Also, you'll want to put newspaper sheets or carton boxes on the corners, walls, or floor near the area to prevent stains all over your place and readily clean it afterward.  

4. Clean the Firebox

Take out any debris or leftover wood using a shovel. Remove or smoothen the old paint using steel wool or a sander. Then, wipe off the dust thoroughly using an old damp cloth and a vacuum. 

5. Carefully Read Instructions

Look at the label from your selected primer and paint to see how many coats of paint are recommended and the drying time needed. Health and safety hazards are also included here, so do note any of the manufacturer's recommendations. 

6. Apply Two Primer Coats, Then Paint

After the primer dries, spread the paint evenly. Start from the innermost to the outermost part. Coat two to three layers for bare and metal surfaces. Use the small paintbrush to fill in the crevices. It will produce smooth and full coverage and avoid dripping paint.

Painting the inside of your gas fireplace is similar to the six steps above, except for Step 4. A gas fireplace does not produce creosote and ashes. Hence, to clean its surface, applying a degreaser is necessary before the primer and paint. 

Should I Have A Fireplace Inspection Before Painting?

Constant exposure to fire may lead your fireplace to normal wear and tear. It is important to have an inspection before starting this project. The Chimney Safety Institute of America recommends scheduling your fireplace inspection by a certified technician every year for maintenance.

How to keep painting safely?

Most paints are safe to use because they are water-based. However, some of them may still emit toxic fumes. These fumes may cause dizziness and skin, eye, or respiratory irritation upon contact. So, always practice these preventive safety measures whenever you are painting:

  • Make proper ventilation by opening the doors or windows 
  • Wear a mask and face shield or goggles
  • Keep the paint away from children’s reach
