Upgrade Your Home With Crown Moulding Corner Blocks

Moulding is a type of wood trim that is used to decorate your home and add a timeless, expensive appearance. Moulding pieces attach to the connections between wall and ceiling or wall and floor. This visually softens the transition and creates a more finished look.


The trim for each part of a room has a different name. Crown moulding is used to decorate the junction between walls and ceiling. Baseboard moulding is used in the connection between the floor and walls. Moulding around windows or doors is called casing or architraves. Lowe's stocks all types of moulding to finish your whole home.


Moulding blocks come in many different materials. Polyurethane blocks have the look of wood but will not split or warp with time. Primed medium density fiberboard (MDF) is a composite material that is easy to paint to match any color. Plastic is stronger than other materials and will resist moisture. You can also use wood moulding blocks to match the material of your walls, ceilings or floors.


Frequently Asked Questions


Q: Can You Buy Moulding Corners?

A: Room edges and corners are easy to adorn with crown moulding corner blocks on the ceiling and baseboard corner blocks near the floor. Trim corner pieces, also called rosettes, are used when pivoting from baseboard moulding or crown moulding to trim around a door or wall edge. Moulding corners make it easy to create a seamless look around your room.


Q: How Do You Install Crown Moulding Blocks?

A: Crown moulding blocks are easy to install. You will need to cut crown moulding blocks to the length needed, then nail each block in place with a nail gun. If small gaps remain between the blocks, you can fill them with paintable caulking.
