Caution: Remember that Polymer undergoes Expansion/Contraction due to variations in temperature. The following instructions will allow for the Expansion/Contraction of the material.
* If using screws instead of nails, all the same instructions apply in regards to spacing and gapping.
Always begin the siding panel installation from left to right and make sure that a wall is completed before beginning a new one. Always begin at the lowest part of the structure.
1.) Always hammer into the installation holes. Each hole features a polymer film that allows for precise centering of the nail and ensures proper expansion and contraction of the material. Every river rock siding panel must be nailed by 5 nails in the nailing channel at maximum intervals of 16" (40,64cm) or less. If your faux river rock siding panels are installed on a furring wall, a furring strip is required behind each nail. Always use non-corrosive nails or screws that can penetrate a minimum of 3/4" (1,91cm) into a solid surface.
2.) When hammering nails, be sure not to hammer the nail in completely leaving a gap of 1/16"(0,16cm). The stoppers located around the holes help to provide the required gap by keeping the hammer from driving nails in too far.
3.) Make sure that all pieces are properly joined together.
4.) When using trim (i.e. Novi One-Piece Trim), leave a space of ¼" (0,64cm) between the inside wall of the trim and the siding (Figure 4). For further information on the use of trim, see our Novi One-Piece Trim installation guide.
Note: We recommend using a circular saw with a finishing blade when cutting the material.
1.) Begin by installing the starter strip at the lowest point of the structure. The horizontal starting line should be perfectly leveled and square with the wall. If using Novi One-Piece Trim, leave a 1/2” (1,27cm) gap at each end of the wall (1). When there is a floor against the wall, you must make sure to leave a 1&5/16” (3,33cm) gap between the starter and floor (2). If there is no floor, your starter strips should be flush with the base of the wall.
Nail the starter strips through the nailing holes at maximum intervals of 8” (20,32cm) or less. DO NOT FORGET to nail in the center hole (3). Install the following starter strip by sliding it left to the stopper in the previous one and then nail it as mentioned above (4). We recommend using galvanized roofing nails that will penetrate the solid surface to a depth of 1&1/2’’ (3,81cm). When installing onto concrete, use 3/16’’ (0,48cm) dia. round head self-drilling screws (e.g. tapcon®) that will penetrate the concrete to a depth of at least 1’’ (2,54cm). Take into account the thickness of the panel.
Note: Refer to the Tips & Tricks section at the end of the siding installation instructions for installations using regular trim at the bottom of the wall to achieve a more finished look.
2.) Cut a 36" (91,44cm) length of starter strip and screw it into bumps on the back of the faux river rock siding panel. We recommend using non-corrosive screws #8 3/4" to fasten the starter strip.
3.) When using Novi One-Piece Trim, cut the left side of a panel in a straight line, insert the panel into starter strip and slide it under the Novi One-Piece Trim. Leave a space of ¼" (0,64cm) between the inside of wall trim and the siding panel. Measure your wall length to determine where to cut your first panel to avoid having a very small piece at the right end of the wall. Make sure to align adjacent walls. It may be necessary to cut the edge of the trim to provide a nicer fit with the panel.
4.) Hammer a nail into the center hole of your panel (Figure D) to ensure even movement in both directions during expansion/contraction. Then hammer nails into the last hole on both ends and into the lateral holes. If the panel is installed on a furring wall, a furring strip is required behind these holes.
Note: If any panel piece is lacking the initial center hole in the middle, you will need to drill a new center hole with a 1/8" (0,31cm) diameter at the same height as the other installation holes. Each full length panel should be secured with a minimum of 5 nails plus the nail into the lateral hole.
5.) Cut another 36" (91,44cm) length of starter strip and screw it as mentioned in Step 2. Hook the second faux river rock siding panel into the starter strip and slide it over the previous panel. Make sure that the tabs on both sides are locked together and spaced equally. If installing at an outdoor temperature over 68°F (20°C), slide panel to the stoppers located at the back of the panel.
6.) Once resistance is felt, do not force insertion of part. Use the reference line located on the front of the siding panel to validate correct positioning. When installed at an outdoor temperature under 68°F (20°C), adjust the panel to the temperature line indicated. Repeat this step until the end of wall.
7.) For the final row, or in places where you may need to attach siding other than in installation holes, at a concealed spot on the panel use a knife to create new slots 1/2” (1,27cm) wide for nailing. The slot must be wider than the nail but not as wide as the nail head. Although not set in the pre-made installation holes, this type of cutting will allow for proper expansion and contraction movement of the siding panel.
8.) For a neater/more finished look, you may install the first rows of panels using regular trim at the bottom of the wall instead of using Novi One-Piece Trim. To do this, install starter strips at 1&13/16" (4,60cm) from the wall's bottom or above the ground and then install the regular trim base under them. Continue your installation from step 2 of these siding installation instructions. Once the first row of wall is completed, install a regular trim top to the desired depth.

Note: Regular trim can ONLY be used at the bottom of a Novi Plus siding panel installation for a more finished look and cannot completely replace the use of Novi One-Piece Trim.
