DuraLife Porch Collection Installation Instructions Updated: 1/11 www.gaf.com
1 Getting Started... ilation and Drainage Plan the design of the porch it is the beginning of a successful project. DuraLife Porch Collection flooring should only be used on covered porch applications. 1. Completely read the application instructions before starting the installation of the porch. 2. Properly unload and store DuraLife Porch Collection flooring Do not dump or drop flooring from the back of a truck or trailer. Flooring should be off-loaded by forklift or by hand. Store flooring on a level area on wood supports placed every 3 feet (914 mm). Protect DuraLife Porch Collection flooring... during storage with lumber cover or tarp. Use proper lifting techniques when lifting DuraLife Porch Collection flooring; it is heavier than standard wood materials. 3. Use proper joist placement to realize savings in both time of installation and cost of materials. Make sure the joist direction maximizes the desired lay-out of the porch. Typically the joist direction is parallel to the structure so that DuraLife Porch Collection flooring can be installed perpendicular to the structure for optimal drainage. 4. Follow all local and state building codes when planning and installing your porch. 5. Use normal wood working tools to cut, route, or fasten DuraLife Porch Collection flooring. For cutting, use carbide-tip saw blades with approximately 2 teeth per inch (approximately 2 teeth per 25 mm). 6. Tools needed Cordless drill Drill and countersink bit #1 square drive bit Circular saw Tape measure Chalk line Router (optional) 7. Always use personal safety equipment when using tools. 1. To perform properly DuraLife Porch Collection flooring must be installed with proper drainage and ventilation. 2. Ensure that: a. There is proper slope for drainage 1/4 per foot (21mm/m) slope of the porch away from the structure is required to provide for optimal drainage. b. There is proper clearance from grade for ventilation the substructure must have at least 2 (51 mm) clearance from grade. (See below for exception for installation on a sleeper system.) 3. Never attach DuraLife Porch Collection flooring directly to any solid surface, watertight membrane, concrete, or existing decking. 4. If installing the porch on a solid surface or watertight membrane use a criss-cross sleeper system consisting of pressure treated 2 x 4 (51 x 102 mm) lumber laid flat. The system must be secured to the surface below and the bottom sleeper must follow the
Second Floor Porch Installation direction of the slope. If the porch is installed over a waterproof membrane, the sleeper system must be properly flashed into the membrane system to maintain the waterproof integrity of the membrane system. 5. DuraLife Porch Collection flooring will not provide a watertight covering water will flow between the flooring. 6. Never obstruct ventilation by placing barriers that prevent air flow from reaching the bottom of the porch floor. ( See Drawing #1 for proper ventilation requirements.)

Use minimum nominal 2 x 8 (51mm x 203 mm) sized joist for porch frame constructions. Use KDAT (kiln dried after treatment) stamped framing lumber since it is typically straighter, Three Wall lighter, Installation easier Side to View handle, and will not shrink or expand as much after installation as non-kdat lumber. 2.

Use 16 (406 Floor mm) Register on center joist spacing starting with the ledger board. Install detail DuraLife Porch Collection flooring perpendicular to the joists. (See Drawing #2.) 4. Confirm required joist spacing with local and state building code agencies. 5. If heavy equipment is going to be installed on the porch such as a hot tub, consult the equipment manufacturer for specific requirements for framing and support. Do not install heavy equipment directly on top of DuraLife Porch Collection flooring. 6. Install the framing joist vertically with the 2 (51 mm) side in contact with the flooring. Do not install DuraLife Porch Collection Drawing #2 flooring on framing that has been installed flat with the 8 (203 mm) side in contact with the flooring because this may cause debris and moisture to be trapped between the framing and flooring resulting in premature deterioration. 2 Blocking is REQUIRED Where The End of Two Deck Boards Meet When the design of the porch is wider than 16 (4.9 m) or it is a unique design blocking ( sistering ) or additional framing is required. 1. DO NOT share joist or fasteners at butt end joints of the flooring the ends of each board must be individually supported and fastened (See Drawing #3). 2. Transition/divider boards or other intricate designs require additional blocking or framing. Drawing #3
flooring SPacinG or GaPPinG Drawing #4 color and orientation of the flooring fastening All porch flooring expands and contracts as the temperatures and seasons change. When installing DuraLife Porch Collection flooring always space fl ooring to provide the following minimum gaps to allow for these changes: Side to Side do not hammer fl ooring tightly together. A slight gap of approximately 1/32 (0.8 mm) is built into the product for expansion and contraction. End to End typically 3/16 (4.8 mm depending on fl ooring length and temperature (see Chart 1 - Spacing Calculator.) Structure 1/4 (6.4 mm) between all fl ooring and any structure or post. DO NOT place columns, posts, or other parts of the structure on top of the DuraLife Porch Collection fl ooring. Create a plywood island under any load bearing column, post, or heavy equipment. Creating a slightly thicker (1 (25 mm)) plywood island underneath area of the load will allow the load to be transferred without going on top of the fl ooring (See Drawing #4). Follow all local and state building codes. DuraLife Porch Collection flooring must not be installed in a picture frame method because of the slight amount of expansion and contraction. Install DuraLife Porch Collection flooring at temperatures above 30 F (-1 C) to allow for correct spacing. 1. Always lay out the flooring before fi nal installation to ensure an acceptable color mix. There are slight variations in color from board to board. 2. DuraLife Porch Collection Flooring may be primed and painted do NOT use stain on your DuraLife Porch Collection fl ooring. DuraLife Porch Collection is available in a weathered grey color and does not require painting. DuraLife Porch Collection may be primed with a premium alkyd porch primer and fi nished with a high quality porch and fl oor paint. For more information about the alkyd porch primer, contact Duarnt Performance Coatings at (800) - 420 0021 Note: DuraLife Porch Collection fl ooring will naturally weather to a lighter shade of grey over time. Stainless steel screw fasteners are required for installation of DuraLife Porch Collection fl ooring. 1. Use #7 x 2 1/4 stainless steel, trim head deck screws when installing DuraLife Porch Collection fl ooring - these are available through your DuraLife Porch Collection dealer. 2. DuraLife Porch Collection flooring is pre-drilled so that the fi rst hole is 5/8 (16 mm) from the edge and will attach to the ledger. Holes are 16 (406 mm) on center from the fi rst hole. 3. Pre-drill and countersink when the factory drilled holes do not line up with the framing. A 7/64 drill bit diameter with a 1/4 60 countersink is optimal. 4. Pre-Drill at a 45 angle through the tongue of the product when drilling additional holes. 5. For corner and butt applications pre-drill and countersink. Fasten with #7 x 2 1/4 stainless steel, trim head deck screws. For corners use a transition board that extends out from the corner at a 45 angle. This board will need to be face fastened and the tongue ripped off. This will allow for the gap to be split on both sides of the board. (See Drawing #5.) 6. Never place fasteners closer than 5/8 (16 mm) from the edge or ends of the fl ooring. Helpful Hints: Take a measurement of the total width of the installed fl ooring to make sure they are parallel every 7-8 courses. 3
Finishing The Installation For Stairs Use DuraLife Porch Collection Stair Tread For Trim Use DuraLife Porch Collection Trim Care And Cleaning Trimming may be needed after all porch flooring has been installed: 1. DuraLife Porch Collection should NOT extend more than 1 (25 mm) beyond the framing in any direction. 2. Use a white chalk line to provide a cut line for squaring off the porch. Caution: Colored chalk can stain the flooring and can be very difficult to remove. 3. Use a circular saw to trim the ends of the DuraLife Porch Collection flooring along the chalk line. DuraLife Porch Collection Stair Tread is available for use on stair applications. Install by: 1. Leaving a minimum 3/16 (4.8 mm) gap between stair treads for proper drainage. 2. Leaving a minimum gap of 1/8 (3.2 mm) gap between the riser board and the stair tread. 3. Face fastening with #8 x 2 1/2 stainless steel, trim head deck screws. DuraLife Porch Collection Trim is available from your DuraLife Porch Collection dealer. Install by 1. Pre-drilling and countersinking every 12 on center. 2. Face fastening with #7 x 2 1/4 stainless steel, trim head deck screws. 1. To maintain the appearance of your DuraLife Porch Collection flooring sweep periodically and clean spills with soap and water. 2. If grime, ground-in dirt, mold or mildew becomes a concern consult the DuraLife Porch Collection cleaning instructions online at www.gaf.com or call 1-877-332-5877. Caution: Only use pressure washers for low pressure wetting and rinsing. High pressure washing can damage the surface of the decking. Always test all cleaning products on an inconspicuous area before using on the entire porch floor.
