Note: As with any installation, prep work will influence the finished job. Take the time to make sure all the wall surfaces are solid, smooth, and flat. The cove stick should be a quality, rigid or semi-rigid material that will adequately support the flooring material.
1. Install the cove stick: Mark the beginning and end of the outside corner radius on the cove stick. Using a miter box, make relief cuts approximately 1/8-inch apart between the marks (Photo 1).Cut from the bottom of the cove stick to the back, taking care not to cut all the way through. Install the cove stick, making sure the cove radius is uniform around the corner (Photo 2).
2. Install the cove cap:
Mark the beginning and end of the outside corner radius on the cove cap. Insert a scrap of the material to be installed in the cove cap in the area to be bent; this will keep the cove cap from collapsing when bent. Form the cove cap around a pipe of similar radius as the outside corner (Photo 3). Bend slightly past 90 degrees; the final shape can be “fine tuned” on the actual corner.
3. Make the pattern: Cut scribing felt to fit for either the T-Template or Full Felt (scribing felt up the wall) scribing method. If using the Full Felt method, cut the felt away from the outside corner so that the entire corner and cove stick is exposed. Mark the pattern for the top of the cove cap on each side of the outside corner using standard scribing methods (Photo 6 - A T-Template was used here). Align a straightedge with the bottom of the cove stick on one side of the corner and mark the pattern on both sides of the straightedge at the corner. Repeat for the other side of the corner (Photo 7). Mark a straight line from the bottom of the cove stick through the corners of the box formed by the marks from the straightedge (Photo 8). This line is the center of the corner.
Locate a point on the cove stick approximately 1/3 of the way down from the top, and in the center of the corner. Using dividers set at approximately 3 inches, strike an arc from the mark on the cove stick that intersects the corner center line (Photo 9).
4. Transcribe the pattern:
Transcribe the marks for the top of the cove cap. Take care not to mark past where they intersect at the corner (Photo 10). Place masking tape on the material at the bottom of the corner and, using a sharp pencil, extend the corner center line onto the tape.
5. Make the cutout for the outside corner fill:
Scribe a line from the intersection formed by the lines for the top of the cove, to the point at the bottom of the corner. Measure up from the mark at the bottom of the corner approximately 3/4-inch along this line. Using that point as the center, scribe a circle that goes through the point at the bottom of the corner. The actual radius of the outside corner may vary from job to job, and will determine the best size for this circle.
6. Install the field material: Use tape to reinforce the bottom of the corner cutout. Do not spread adhesive in the area of the corner fill. The test cutout from Step 5 can be used to mark adhesive spread lines at the corner. Install the field material, carefully forming it around the outside corner (Photo 14). A heat gun on a low setting will make the material more pliable and help avoid damage at the bottom of the outside corner. Make sure the material conforms tightly to the radius of the cove stick.
