Crown molding
Crown molding is adds a charm to a house as well as value. Trimroc molding is, according to experts, the best to use in a do it yourself project. It cuts easily and smoothly and goes up in a flash and, believe it or not, can be finished in a weekend.
In preparation of your crown molding project, measure the room at least two weeks in advance.
First off, you will want to lay out and cut the molding. Focus on making the crown molding look parallel with neighboring trim, starting at an inside corner and working to outside corners. Some walls may not be level so allow you eye, instead of a level to guide your positioning. Hold a strip of the molding above a door or window and adjust it until it looks even. You may want to get someone to stand back and give you their opinion. Next, draw a line with a pencil to mark the positioning that you will be installing the materials.
Place the material in a miter box upside down and brace it against the bottom and side of the box in order to cut it. Use a handsaw and cut the molding at a 45 degree angle. Note: on an outside corner, the bottom part will be shorter and on an inside corner the top part will be shorter.
Now be sure there is a tight fit by using a sanding block or rasp to shave the cut and create room for the corners to come together tightly.
Now you are ready to install the molding. Joint compound will make the molding adhere to the wall. Note: too much of the compound will cause the material to slide down the wall. As the compound is drying, support long runs of molding with nails (8d). Then, using a putty knife, you will spread a ½ inch bead along the length of the molding both on top and on bottom with liberal amounts on either end of the cut.
The two mitered ends should be pushed together creating the inside corner. Be sure their faces align in the corner. Use mud to fill small gaps.
On an outside corner, press the mitered ends together until mud squeezes out of the joint and backfill gaps using your finger or a putty knife.
Use 8d nails under the molding every few feet and at the joints to hold the material in place, making sure you angle the nails upward. Create butt joints by pushing straight cut ends.
Note: Cleanup will be easier if you clear away excess joint compound while it’s still wet.
Using your finger, smooth out any seams. Now a wet sponge or cloth will wipe away the residual compound and clean up the molding.
Using a putty knife, pulling over each detail, push more compound into and over butt joints. Any excess can be sanded away.
After sanding to smooth out all the rough edges and compound has dried completely, use 150 grit sandpaper to smooth the area. Now you will want to mask the walls with tape and use an angled brush to paint the molding to match the doors and windows of your home.
