Tools and Supplies You'll Need

  1. Nails or Screws
  2. Hammer, Screwdriver or Screw gun with the appropriate tip for the screws being used.
  3. Snips or Saw for cutting siding (we recommend using a circular saw with a finishing blade.)
  4. Drill
  5. Tape Measure
  6. Level
  7. Aluminum or Flashing
  8. Some type of color complimenting caulk to apply as necessary
  9. Utility Knife

Directions:

Caution: Remember that Polymer undergoes Expansion/Contraction due to variations in temperature. The following instructions will allow for the Expansion/Contraction of the material.

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.

General Information

Hammer nails into pre-made installation holes for proper centering.

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.

Do not hammer nails down completely.

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.

Join the simulated river rock siding panels as shown.

3.) Make sure that all pieces are properly joined together.

Make sure to leave the recommended gap if using Novi Trim Plus.

4.) When using trim (i.e. Novi Trim Plus), 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 Trim Plus installation guide.

Note: We recommend using a circular saw with a finishing blade when cutting the material.


Installation Steps:

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 Trim Plus, 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 Novi Trim at the bottom of the wall to achieve a more finished look.

A length of starter strip on the back of the panel will ensure correct placement during install.

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.

Your panels will need to be cut to sit correctly against Novi Trim Plus.

3.) When using Novi Trim Plus, cut the left side of a panel in a straight line, insert the panel into starter strip and slide it under the Novi Trim Plus. 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.

Locate the central hole and lateral holes on your siding 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.

At warmer temperatures, simply slide panels together until you reach the stoppers.

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.

A marked line of the front of the panel shows where to place panels in colder temperatures.

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.

Alternate panel cuts to help hide seams and repeating patterns.

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.

The last row may need new nailing holes cut in order to be finished.

8.) For a neater/more finished look, you may install the first rows of panels using regular Novi Trim at the bottom of the wall instead of using Novi Trim Plus. 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 Novi 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 Novi Trim Top to the desired depth.


Tips and Tricks:

Regular Novi Trim at the base of your river rock siding panels can give a neater appearance.

1.) For a neater/more finished look, you may install the first rows of panels using regular Novi Trim at the bottom of the wall instead of using Novi Trim Plus. 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 Novi 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 Novi Trim Top to the desired depth.

Note: Regular Novi 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 Trim Plus.
