• Deck Boards that are not secured to the joists may be loose and unstable.
• Walking on loose and unstable Deck Boards could cause a fall resulting in serious injury.
• Do not walk on loose Deck Boards that are not secured to the joists.
Before starting this project be sure to consult your local building department for codes and regulations for deck, guard rail, hand rail, and stairway installations. Read all of these instructions before beginning your project. Do not attach Rail Posts or any other structural member directly to
Genova Vinyl Deck Boards. Any Deck Board that has been cut (as for a post) must be supported underneath.
This product is not approved for use in commercial installations, access ramps for the disabled, or marine fueling stations. Call MISS DIG to locate all utilities before starting your deck installation. The temperature of the deck boards should closely approximate the outdoor temperature before cutting and installing. It is recommended to design decks without butt joints whenever possible.
Genovations Decking is a PVC product with no wood or organic fibers added and resists most stains. Genovations Decking will not absorb any moisture. Genovations Decking is virtually maintenance free. Normal airborne pollutants and dirt from every day foot traffic can be easily cleaned off with a garden hose and spray nozzle. For tougher stains use non-abrasive soap and water, and apply with a soft bristle brush. Wipe up large spills and clean with soap and water. A power washer may be used to clean Genovations Decking (1500 psi with a fan tip nozzle, 12" above deck). Do not use any citrus based cleaners or solvents on Genovations Decking products. Rubber mats, or rugs with rubber backing can cause a reaction and discolor the decking surface. Fiber or bristle rugs are recommended. Use calcium chloride for ice removal, broom for snow. Do not chop ice and snow off of decking with sharp edge tools or shovels. Excessive heat can cause damage; allow for adequate air flow around gas and charcoal grill. Avoid splattering of cooking grease. Avoid spraying pesticides on or near decking.
1.
Install the wood deck frame in accordance with approved construction techniques. Joists should be installed on a maximum of 16” centers.
2.
Cut Deck Starter to proper length with consideration for finishing open Deck Board ends:
L-Molding with Trim Board (Figure A)allow 3/8” overhang
C-Channel & Trim Strip (Figure B)-allow 1¼” overhang
Screw the Deck Starter on the ledger board (closest to the house).
3.
Place the tongue of the first Deck Board into the groove of the Deck Starter. Align the screw slots over the center of the supporting joists. Add a wood nailer adjacent to the joist if necessary (Figure A).
Fasten Deck Boards tightly at every joist.

4.
Cut the last Deck Board to width, again with consideration for proper overhang. (If necessary for support, such as the top of a stair, cut a piece of treated lumber to fill the open slot in the last Deck
Board). Install one Stair Screw Insert and Plug (see Stair Installation Instructions 5-7) at each joist to secure the outboard edge of the last Deck Board.
5 Trim the Deck Boards to length. Install L-Moulding, C-Channel or Trim Strip on all cut edges. Apply
Genova Vinyl Sealant between the underside of the L-Molding (Figure A) and C-Channel or Trim Strip
(Figure B) and the Deck Board. Attach Trim Boards using two 1¼” screws. Pre-drill screw holes 1/8” larger than screw used. Install fasteners not less than ½” and no more than 2” from the edge of the
Trim Board.
1.
Stair steps must be supported with step stringers on maximum 16” centers (Figure D). Each step requires two Deck Boards, one Trim Board and one Step Trim. Cut stringers with a maximum rise of 7” and a run of 10¼” to provide stair treads with a 3/4” nosing. Add filler boards (if necessary) to adjust the deck board overhang to ¾”.
2.
Cut the Trim Board length flush with the outside edge of the stringers. Attach Trim Boards using two
1¼” screws on every stringer. Install fasteners not less than ½” and no more than 2” from the edge of the Trim Board. Install fasteners not less than 1” and no more than 2” from the bottom of the Trim
Board to allow for the height of the Deck Board.
3.
Position the Deck Board to center the screw slots over the stair stringers. Cut the Deck Board length to provide a 1¼” overhang on each side of the end stringers.
4.
Cut the tongue off the first Deck Board and place the cut edge against the Trim Board (Figure E). Insert screws in the screw slots at each stringer and tighten securely. Cut the Screw Slot Flange off the second Deck Board then cut to length. Insert the tongue of the second Deck Board into the groove of the first Deck Board.
5.
Using a 5/8” “Forstner” bit, drill holes through the top surface of each Deck Board. Center the holes between the Deck Board ribs and over each stringer (Figure E).
6.
Press a Screw Insert (small hole down) into each drilled hole. Drop a #8 x 1¼” screw into the insert and tighten securely, screwing through the bottom of the Deck Board.
7.
Secure the Plugs into the Screw Inserts with Genova Vinyl Sealant, making sure they are flush with the deck surface. Cut the Step Trim to length and secure it into the groove of the second Deck Board by applying Genova Vinyl Adhesive-part #AW945. (Figure E).

Use Genovations Deck Joint Adhesive only (part # DW745) during installation. Deck boards must be clean and dry.
Wear proper eye and hand protection when using. Spread Deck Joint Adhesive with brush dauber provided in can.
Operating temperature 40°F to 110°F. Do not use Deck Joint Adhesive on deck board wood grain surface or trim pieces (Step Trim, C-Channel and L-Molding). A pint of adhesive will cover approximately 20 joints.
1.
NOTE: The goal is to bond Genovations Deck boards together on either side of a butt or miter joint to manage the expansion and contraction. Take great care to avoid any adhesive from making contact with any finished surfaces (deck boards, trim pieces and trim board) because they will become permanently disfigured. Once boards are installed with adhesive, they will not be able to be removed.
2.
Locate and center all joints over double joists, including miter joints. The ends of all boards being butted together must be cut square to assure a tight matched fit (12” miter box saw with 60 tooth blade recommended). Joints should be installed tightly together in all temperatures .
3.
Do not install butt joints directly adjacent to one another. Butt joints should be staggered across the span of the deck. Leave at least 32” between adjacent joints. Boards must be clean and dry.
4.
Place deck board at the point of installation, over joists. Once deck board is in position, turn over so the wood grain surface is facing down. Be careful not to slide deck boards across joists, with wood grain side facing down.
5. With the deck board bottom side up, apply
Genovations Deck Joint Adhesive heavily to the bottom side of the tongue, and the raised edge (step face), opposite side of the screw flange. Spread adhesive in an 8” area, starting from the end of the deck board working back.(See Figure G). Keep in mind you may have to apply adhesive to both ends of this deck board when installing larger projects, with multiple joints.
6.
Once adhesive is applied, quickly turn over deck board and center joints directly over joists. Do not let adhesive dry before board is fastened (one minute). Insert tongue side tightly into groove of the starter strip, or previously installed deck board.
Push deck boards tight together at the joint location.
7.
Using Genovations deck screws (#8 x 1¼” Truss head) securely fasten both deck boards directly to the joists at the joint location. Fasten screws directly through the flange if screw holes don’t line up directly over joist. (See
Figure H). Continue securely fastening screws progressively, moving away from butt or miter joint. Make sure the deck board is pushed tightly into the starter strip or previous deck board before fastening.
8.
Deck boards being installed directly next to (adjacent to) a butt or miter joint also need adhesive applied
(DW745). Place deck board at the point of installation over joists. Once deck board is in position, turn over so the wood grain surface is facing down. With the deck board bottom side up, apply Genovations Deck Joint
Adhesive heavily to the bottom side of the tongue and the raised edge (step face) opposite side of the screw flange.
Spread adhesive in an 8” wide area from both sides of the joint (total of 16”). Keep in mind you may have to apply adhesive in more than one location along this board when installing larger projects. Fasten board by following Step 7.
