Exposed brick walls can define the character of a room, offering a raw, industrial, or rustic aesthetic that drywall simply cannot replicate. However, covering them is often necessary to align with changing design trends, improve thermal efficiency, or create a smoother canvas for paint and artwork. Understanding how to cover brick walls inside house projects successfully requires evaluating the existing condition of the masonry and choosing the right method for your desired outcome.
Assessing Your Brick Wall
Before selecting a covering material, you must conduct a thorough assessment of the wall's current state. Look for signs of moisture intrusion, such as white salt deposits (efflorescence), chipping mortar, or mold growth, as these issues must be resolved before proceeding. Additionally, check for any loose or protruding bricks and secure them to prevent future hazards. The structural integrity of the wall dictates which covering methods are safe and viable, ensuring your renovation is built to last.
Option 1: Drywall Installation
For a seamless, modern finish, installing drywall over brick is one of the most effective methods. This approach involves attaching ½-inch or 5/8-inch drywall sheets to the brick using specialized masonry screws or a thin layer of cement board for extra stability. Because brick is uneven, you will need to use either thick joint compound or resilient washers to bridge the gaps between the studs and the wall surface. The result is a smooth, paintable surface that integrates the wall seamlessly into the room's existing framework.
Preparation and Installation
- Clean the brick surface thoroughly to remove dust and debris.
- Use a hammer drill to secure furring strips or a metal stud framing directly into the mortar joints.
- Attach the drywall sheets, ensuring tight seams to minimize visible joints.
- Apply mesh tape and multiple layers of joint compound for a flawless finish.
Option 2: Plaster or Thinset Application
If you prefer to maintain the wall's thickness while hiding the rough texture, applying a plaster or thinset mortar overlay is an excellent solution. This method involves bonding a gypsum-based plaster or a polymer-modified thinset directly to the brick using a notched trowel. Once cured, the material creates a hard, durable surface that can be sanded smooth and painted. This technique is ideal for those who want to preserve the wall's mass without the bulk of full drywall panels.
Option 3: Wood Paneling or Shiplap
For a warmer, more rustic aesthetic, wood paneling or shiplap offers a classic solution that hides the imperfections of brick while adding character. You can install medium-density fiberboard (MDF) backer board first to create a flat, even surface, or apply the wood directly to the brick using construction adhesive and nails. This method allows for endless design flexibility, as the wood planks can be painted, stained, or left natural to complement your interior decor.
Design Considerations
When choosing wood, consider the scale of the bricks and the room size. Narrow shiplap can make a large wall feel cozier, while wide planks provide a modern, Scandinavian touch. Ensure proper ventilation behind the wood to prevent moisture trapping, which could lead to mold growth behind the panels over time.
Option 4: Covering with Brick Veneer
For those who wish to retain the appearance of brick without the maintenance of real masonry, thin brick veneer is an ideal choice. This lightweight product can be cut to size and adhered directly to the existing brick using a combination of adhesive and mechanical anchors. It effectively conceals stains, discoloration, and minor structural flaws while providing the authentic look of a traditional brick wall. This option is particularly useful in historic homes where preserving the original aesthetic is crucial.
Finishing and Maintenance Tips
Regardless of the covering method you choose, proper finishing is essential for a polished result. Caulking the edges and seams prevents air leaks, improving the room's energy efficiency significantly. When painting, use a high-quality primer designed for masonry to ensure adhesion and uniform color. Maintenance-wise, avoid harsh chemicals on painted surfaces and periodically inspect the covering for any signs of shifting or moisture penetration at the edges.
