    I watched a home improvement show where they painted the seams or gaps on the wall black. That way the gaps don't show thru the wall color. The black seems to make the exposed area fade away.

    I have a wall in my living room that I used cedar fence planks on and the end result is cute!

    Hi Charla, hee's some suggestions I found on the web that you might consider. Just depends on the look you'd like to have in your finished wall.


    You could nail thin battens over the gaps. This has often been done on exteriors.

    You could fill the qracks with black acrylic latex caulk.

    You could press rope into the cracks.

    Are you wanting to fill the gaps to increase the insulation value of the wall, or just to make it more smoother looking?

    Are these gaps to the outdoors??? If so, I'd recommend putting insulation and the siding on the outside of the wall. If this is interior, I like the idea of battens over the gaps or battens on the rear side of the wall to block light/vision to the planked side.

  • It depends on the look you like, but you can use a clear silicone to fill the gaps. I would also ask at a paint store, they will have some really good suggestions.

    Cover the gaps with "battens" (strips of wood). Different size strips of wood would give an intentional amazing rustic look. Stain or "age" the wood strips with paint.

    You can also buy various types of jute rope to chink with (fill in the gap by forcing in with a tool), and I've seen some put a varnish on the rope to keep clean. Comes on big rolls, Etsy and Ebay are good sources.


    You could do a traditional log cabin chink by using split branches to cover the gaps, but it is time consuming.

      You need logs not branches. Who ever heard of a branch cabin?🤭😂🤣😅

    I would hire a contractor and side my house then on the interior wall install sheet rock. If I still have the cedar installed it would be thankfully out of anyone’s line of vision. I would def also insulate while the wall was open.

    I would tack on dowels or lattice boards stained and roughed up to the wooden wall.

    Hi Charla: I have the exact same problem. Since I have access to the back of the walls... I'm thinking of putting stained batten strips behind the gaps. If I didn't have rear access I'd put the stained battens on top. What did you end up doing and how did it turn out?

    Timber Trim or Crown Moulding!

    I think you need to show the actual problem. This picture is a close up of a board.
