CAUTION: Remember that polymer undergoes expansion/contraction due to variations in temperature. The following instructions will allow for the expansion/contraction of the material.
1.) Locate where you want to install Novi Trim and make sure you have nailing in these locations. If installing on a furred wall, make sure to install furring on the nailing locations. Note that there are two bases to install when using the Wide Trim.
2.) Installation around windows and doors or under soffit: Position trim base on the wall keeping 1 3/4" between the base and the window, door, or soffit. Nail as specified in Step 6.
3a.) Installation of an inside corner: Position the trim base on the wall keeping required distance according to the product depth (step 3b.). Nail as specified in Step 6.
3b.) Inside Corner Siding Depth Chart.
4a.) Installation of an outside corner: Position bases along one side of the wall keeping a distance of 1 3/4" from the corner of the wall and nail as specified in Step 3. Then position bases along the other wall making the corner letting the base exceed the corner of the wall according to siding depth (step 4c.) and nail as specified in Step 6.
4b.) When Wide Siding Trim is used to finish an outside corner, install the colored bases at the extremity of the wall's corner and install the clear bases at the rear of the colored bases.
4c.) Outside Corner Siding Depth Chart.
5a.) Installation back to back: Position bases along one side of the wall keeping a distance of 1 3/4" from the corner of the wall and nail as specified in Step 6. Then position bases along the other wall making the corner letting the base exceed the corner of the wall according to siding depth and nail as specified in Step 6.
5b.) Remove Novi Siding Trim tops from the bases you just nailed so you can install siding on the section of the wall, then clip the Trim tops back on bases.
6.) Nail down the center nail first. Make sure the base is straight and leveled. Put nails in the center of each nailing slot on each side of the center hole. A minimum of 7 nails is required per full length base. Never hammer the nails completely down. Always leave 1/16".
7.) To install a second base, align the end of the base on the guide line and nail base as specified in Step 6.
8.) Remove Novi Siding Trim tops from the bases you just nailed so you can install siding on the section of the wall, then clip the Trim tops back on bases.
9.) Install siding or roofing following the guide line located on the base.
Clip Trim to the base starting with one end of the top. Press gradually along the trim until top is clipped uniformly and at the right depth.
To put two tops together, slide second part in the first part following the guide line.
10.) Finishing the corner of a window or door with Trim Corners, Novi Trim, and Novi Wide Trim: Install base around window or door as specified in Step 2a and make sure that they don't exceed the window or door frame on each side. Install siding as specified in Step 6. Cut the tops in straight edge and make sure they are shorter than the window or door framing by 1/4" on both sides. Next, clip them onto the bases.
10a.) Insert Trim Corners between the window/door frame's corner and the Trim tops. Engage properly the Trim Corners' hooks behind the Trim tops.
11a.) Finishing the corners of a window or door trim with Wide Trim; without Trim Corners: Install base around window or door making sure horizontal bases exceed the window or door of 2 1/8" on each side. Install siding as specified in Step 9. Cut the tops that will be placed horizontally in straight edge and make sure they exceed the window or door framing of 3 1/2" on both sides. Then clip them on horizontal bases. Cut the tops that will be placed vertically at an angle of 45 degrees and clip on bases so they cover the horizontal tops.
11b.) Cut the inside hooks of the vertical tops so it doesn't interfere with the horizontal Trim. Add a small screw (screw #4 x 3/4" anticorrosive) on all four corners on the exterior side of the vertical Trim.
1.) Pay special attention to the position of Trim molding junctions. For example, when finishing around the door, make sure the seams are at the bottom of the door to make it more subtle.
2.) To facilitate installing Trim bases around windows and doors, you can use waste pieces of Trim tops to help positioning the bases. To do so, assemble the Trim cap pieces on bases before positioning them on the wall. Push the assembly on the window or door frame and nail on each side of the pieces. Nail gradually throughout the base by sliding the pieces to maintain a proper positioning. Remove the pieces once nailing is completed and continue with the installation of another base or installation of siding.
3.) When using Wide Trim to finish an outside corner it might be easier to complete the installation of the siding on side walls before installing trim bases on the front of the outside corners. By doing so, it is easier to align the bases of the front wall to the thickness of the siding on the side walls.
4.) When using Wide Trim to finish an outside corner, it may happen that you cannot nail in the last nailing hole located at each end of the base because the nail will not penetrate a solid surface. In this case, we recommend you to solidify the installation by making a new 1" long slot at each end of the base nail in these locations.
5.) When installing Trim Corners you may need to straighten up the Trim tops at the junction between the Corners and tops to get a better look. We suggest you put some spacer blocks or screws under the Trim tops to level the assembly. CAUTION: Do not block the expansion/contraction movement of siding. To do so, practice small incisions 1" long on the siding and screw through them.
