How to Cut and Install Baseboards at Rounded Corners. Baseboards really make a room when they're done right. You may find a problem with rounded corner areas, but you need to match existing examples of the baseboards. Learn how to install rounded corner baseboards like a pro.
Things You'll Need
- Baseboard trim
- Table saw
- Finish nails
Measure the area where you need to add new baseboards. Remove the old baseboard material you are replacing.
Select baseboard trim material to match the originals. Mark where the cuts need to go and use a table saw to slice into them in the right place.
Lay the baseboard material to within an inch of the rounded corner. Take a piece of baseboard material and cut it to measure 2 inches in length at 22 1/2-degree angles on both ends. You should be able to butt them up against the straight piece, if cut at the same angle.
Place the smaller piece so that they angle around the curved corner perfectly. While your baseboard is only a close cousin to being rounded, it will create the illusion of the round edge you are after.
Attach the baseboard firmly with finish nails. Add a small amount of caulking to fill any gaps left where the pieces meet. Paint the replacement materials to match the original baseboards.
