Common Uses
Installed at the wall-to-ceiling junction at the correct spring angle. MDF is a paint-only material. It does not accept stain and must be kept dry -- do not install in bathrooms or high-humidity areas.
Pro Tips
- Position crown upside down and backwards in the mitre saw -- ceiling edge flat on the saw table, wall edge against the fence. This is the correct cutting position for compound mitres.
- Apply two coats of quality interior latex paint in satin or semi-gloss directly over the factory primer. Seal all cut edges with primer before painting -- exposed MDF edges absorb paint unevenly.
- Nail crown into both wall studs and ceiling joists for a secure installation. Use a stud finder to locate both.
Frequently Asked Questions
What is spring angle?
Spring angle is the angle at which crown sits between wall and ceiling. Common angles are 38/52 and 45/45. The flat edges on the crown back determine the angle.
Can I use MDF moulding in a bathroom?
No. MDF absorbs moisture and swells irreversibly. Use solid wood (hemlock or cedar) moulding in bathrooms and high-humidity areas.
