How To Install Baseboard On Rounded Walls

Baseboard material flexes only a small amount before the tension released by bending the board eventually gives way and the baseboard breaks.

However, you have multiple choices for installing baseboard to rounded walls.

First, you can score the wood in a manner that makes it easier and flexible to bend.

The other option is to buy a manufactured material that easily follows the curves then install it.

Manufactured baseboards are created to fit both the inside and outside curves whereas wood baseboards can only be scored to fit an outside curve.

In this article, I will explain how to install both baseboards on rounded walls.

Scoring Wood

Run a string from the starting point to the ending on the curve.

You will need to identify where your two points depending on the type of baseboard molding that you have in place, the length of the baseboard, and the radius of your curve.

Cut square ends or miters on every side of the wood baseboard.

This will depend on how you intend to join the additional pieces and whether or not the board will stop at a door frame or a similar area.

Fix the miter saw’s depth so that it plunges only two-thirds of the way in the baseboard and within one-eighth of the baseboard molding’s top.

Here, you can use a scrap piece of that baseboard material to alter and test the cut’s depth. The reason for stopping the cut at one-eighth of the molding’s top helps to keep the cuts (kerfs) from being visible on the completed piece.

Cut kerfs on the back of the baseboard material that you intend to curve around the rounded wall.

It is best to space the kerfs to be one eighth apart along the baseboard’s length. These cuts will help the baseboard material to easily bend.

Anchor each of the molding ends with two screws and drive them using a power screwdriver (if you need something smaller see the best pocket screwdrivers) into the studs behind your wall.

The anchors will alleviate the pressure on the curved baseboard.

Hammer the finishing nails into the baseboard material and the studs at the drywall.

Flexible Baseboard

Run a string from the curve’s starting point to the ending point.

Identify where your two points will be depending on the molding that you have, the length of the baseboard material, and the radius of your curve.

Cut square ends or miters on every side of your flexible baseboard.

This will depend on how you intend to join the additional pieces and whether or not the board will stop at a door frame or a similar area.

Using a powered miter saw is effective because it cuts easily through the manufactured baseboard.

Apply some construction adhesive on the back of the flexible baseboard.

Draw two parallel lines – one that is half an inch from the baseboard’s bottom and one that is half an inch from the top.

Press the flexible baseboard along the rounded wall.

Hammer the finishing nails into the baseboard material and the studs at the drywall.

Here is the guide that you should follow if you want to know how to install baseboard on rounded walls.

I advise that you start by selecting your baseboard material and pre-sand it to avoid getting an uneven finish.
