Guide for Cutting And Installation Of Crown Molding
Crown moldings are the moldings used on ceilings, which elevate the aesthetic appearance of the rooms and give it a finished look. The wide variety of crown molding materials and designs available today makes it easy for people to finalize on the best option to decorate their house. The installation of some materials is easy while others require help from professionals. Installation is simple and easy compared to cuttings the angles for corner pieces which require expertise and precision.
When installing crown molds, it has to be cut to get the corners perfectly. This cutting is of four types depending on the situation. A suggestion if you are planning to cut the molding by yourself is that, first practice to learn how to install crown molding and by cutting scrap pieces, you can practice for cutting crown.
Below is a small guide on how to cut crown molding.
1. Selection of the molding
The first and foremost task is selecting the crown molding you need. You need to know the right proportion of the crown molding required to complement your room. The next task is buying a molding that is affordable, malleable and durable at the same time. Shopping locally is the best choice as you can seek help from local suppliers who specialize in millwork. They can offer extensive molding selections and give some expert advice on installation.
2. Selecting the right work tools
The second most crucial task is selecting the tools required for molding. This includes a template, chalk line, stud finder, spiral blade fitted oscillating tool, block or dowel, sandpaper, finish nailers- 16 gauge or 18 gauge, safety glasses and gloves.
3. Setting up reference lines
Using the template crown molding, mark the edge of the template touching the wall and ceiling. Using chalk, pencil or tape mark these lines as these are your reference lines for fitting the crown moldings.
4. Trail testing
By assembling the template molding or the scrape molding in place of the actual pieces, you can understand the adjustments required to fix the molding perfectly against the ceiling and wall. You can also know how tight the corner joints are.
5. Fixing ceiling boards
The reference line drawn earlier should merge with the edge of the molding on the positioning. Sometime due to some bulges on the wall, the molding may not align perfectly with the ceiling. To rectify this problem, you need to some portion of the molding’s back edge to make space for the bulge on the wall. When attaching the board to ceiling, make sure to long screws that are capable of penetrating deep into the wood. You can also use toggle bolts instead if you cannot get long screws.
6. Cutting crown molding
There are certain practices to remember while cutting moldings. These are:
· To get the best crown molding angles, cut using a power miter saw. This saw can be adjusted to cut at any angle- 45° to left or right.
· Make sure that the crown molding’s wall edge will rest on the vertical fence of the saw and the ceiling edge of the molding rests on the horizontal fence of the saw.
· To get an inside corner on the right side of the wall you should pivot the miter saw to 45° to the left and use the left end of the cut piece. Follow the opposite for getting an inside corner on the left side of the wall.
Making Crown moldings with square cuts
These are the simplest cuts which are used for making butt joints. The cut ends of this type of moldings will fit at the same level as the molding. To achieve this, set the miter saw to 0° and create a butt joint.
Making Scarf joints on crown molding
Scarf joint cutting is made when the wall is longer than the length of a single piece of crown molding and requires a connection made of two pieces of trim. This is achieved by cutting two trims at 45° opposite angles and joined by overlapping as a splice.
Making of outside corners
Outside corner crown molding is required when the room has more than four corners. This can be the tall windows, an entryway or a chimney which prevents the crown molding from outlining a rectangle or square on the ceiling. Tor these, the moldings are cut to create a shape like a ship’s bow.
Making of coped joints for inside corners
When you use coped joint you can create a tight seam for inside corners of crown molding. This can be created by using a handsaw called coping saw. This removes the molding material from the back of the moldings leading edge. The need for doing this arises when there are gaps in the joints of wall corners which leaves an unfinished look. On scraping the molding material only the decorative front profile is left which will then fit perfectly against its matching piece in the corner.
You can also make use of pre-cut decorative corner blocks on the area where wall corners meet the ceiling. These will eliminate the need for making any angle cuts using miter saw. Using sandpaper to smoothen out any high spots on cut ends will ensure tight joints.
7. Attaching of molding
After cutting the crown moldings in the corners snap it firmly into place and then fix using nails or constructive adhesives. When attaching cut moldings ensure that the corner edges overlap perfectly to avoid visible gaps.
8. Cleaning up after installation
Once the installation is complete you should clean up the outside corners by using sandpaper to smoothen out the line created by joining pieces. You should use caulk for gaps formed in paint-grade molding installations. Also, remember to use lightweight spackles to fill nail holes instead of caulk which tends to shrink on drying.
Following this guideline while installing crown moldings will save you lots of time, frustration and money. Crown molding installation can be done by yourself if the material used is not too demanding. Crown molding helps in creating a feeling of the high ceiling in the rooms in which it is installed.
