Treated Wood
Q: Why should I use treated wood joists and beams to support my deck?
A: Treated wood guarantees a much longer life for the understructure of your deck. Since many of today’s composite decking products are guaranteed for 20 years or more, it is unwise to use untreated lumber for the deck structure. Even in dry climates, it is advisable to use treated joists, and many decking manufacturers require the use of treated lumber to maintain the warranty.
Q: What is happening with the new treated wood?
A: At the end of 2003 all lumber treaters discontinued the use of CCA in treating residential products. CCA was a very effective treatment chemical for many years, but concerns about the ingredient arsenic made it advisable to change to a new generation of chemicals.
Q: Are my old structures made out of CCA safe?
A: Yes. The EPA has advised that the change to the newer chemicals was a cautionary step and that it is not necessary to remove older CCA treated lumber structures.
Q: Can you give me more information about the new treated chemicals?
A: McFarland Cascade treats our residential lumber with CA, or Copper Azole. This product is effective in prolonging the life of lumber used in outdoor applications. CA contains only copper and an ingredient that helps fight copper tolerant fungi. CA is not classified as a hazardous substance, and can be disposed of in traditional landfills, whereas CCA cannot. CA is safe for use in all outdoor structures, including play sets, sandboxes, etc.
Q: How does lumber treated with CA rate as an environmental product?
A: Using treated lumber greatly extends the life of the structure built, reducing the replacement cycle for that structure and the amount of material required to rebuild a non-treated structure. During the past 20-30 years, the pressure treating industry has helped save forest area equal to the size of New England by increasing the effective life of outdoor structures.
Q: What is ACQ?
A: ACQ is another alternative chemical used to treat residential lumber. McFarland Cascade believes that CA rather than ACQ is the most effective alternative available today, and we only warranty structures built using CA treated lumber from McFarland Cascade.
Q: Should I seal my Extra Green Outdoor Select decking?
A: Yes. You should immediately seal your decking if you built it using our Outdoor Select pressure treated lumber. Any quality brand of water repellent sealer will be effective in reducing the effects of weather on your deck. It is necessary to perform a sealing every year to preserve your deck and its warranty.
Q: What does the warranty for Outdoor Select decking cover?
A: Our warranty for all Extra Green treated lumber with Copper Azole covers any product damage from fungal decay to termite damage. It does not cover damage from checking, splitting, twisting or other natural tendencies of wood.
Q: What fasteners should I use with CA treated wood?
A: Because of the high copper content of CA, extra care needs to be taken in the selection of fasteners. All hangers and fasteners must be hot dipped galvanized to the G185 standard. A common brand name that meets this standard is Zmax, manufactured by Simpson Strong-Tie. Stainless fasteners are recommended for best results in marine climates. Never mix stainless fasteners and galvanized hangers or vice-versa.

ExtremeRedwood Tropical Hardwood
Q: Do you need to store ExtremeRedwood Tropical Hardwood out of the sun?
A: Yes. The product must be stored until you have applied penetrating oil with UV inhibitors on all 4 sides (Exotic Hardwood Penofin from Performance Coatings, U.V Plus for Hardwoods from Messmer’s and Olympic Maximum Green Label)
Q: Do you need to leave spaces side to side?
A: Yes. Wood will expand and contract as it takes on moisture and evaporates. Please refer to installation guide for proper spacing.
Q: Do you need to have adequate ventilation and a vapor barrier underneath the deck?
A: Yes. You need to build your deck at least 16” off the ground so there is air circulation to prevent cupping and warping of the deck boards. In addition, there should always be a vapor barrier between bare ground and the deck.
Q: Do you need to use stainless steel screws?
A: We recommend the use of stainless steel screws after pre-drilling through the face of every deck board, two screws per joist.
Q: Do you need to seal the ends after cutting?
A: Yes. We recommend that the boards are end-sealed as soon as possible after cutting. A clear water resistant wax should be used.
Q: What is the recommended joist spacing for deck boards?
A: 1x4 and 1x6 deck boards need to be installed on 16” centers. 5/4 x 4 and 5/4 x 6 deck boards need to be installed on 24” centers.
Q: Will ExtremeRedwood Tropical Hardwood fade?
A: Yes. ExtremeRedwood will change to a gray color over a period of time. To help slow the process, re-apply penetrating oil with UV inhibitors every year.
Q: Does ExtremeRedwood Tropical Hardwood check or split with weather changes and exposure to the sun?
A: Yes. Any wood product will check and split due to exposure to the weather and sun; however, continued yearly use of penetrating oil with UV inhibitors will also help slow down the process.

RainEscape™
Q: Can the RainEscape™ system be added to an existing deck?
A: Yes. In most cases, the RainEscape™ system can easily be retro-fitted to any existing decks.
Q: Can I install the system myself?
A: Yes. For most decks, the easy to follow instructions (included), a pair of scissors and a staple gun are all you need to install the system.
Q: How do RainEscape’s™ prices compare to other similar systems?
A: Although RainEscape™ is a relatively unique drainage system it costs approximately 70-80% less than the nearest competitor.
Q: How long does the RainEscape™ system last?
A: With the 20 ML plastic and Ultra Violet inhibitors, the RainEscape™ system is extremely durable.
Q: How do you clean out the debris?
A: There should be little if any debris entering the system, as it has to be small enough to fit through the decking. Small debris simply passes through the system with water. In the rare case of minor build up, simply remove the piece of decking over the affected area and clean as needed.
Q: Is RainEscape™ affected by freezing temperatures?
A: If the system is installed correctly, any water that is caught drains out through the downspout in a matter of seconds. Since there is no water remaining in the system, freezing is not an issue.
Q: What are the overall benefits of the RainEscape™ system?
A: RainEscape™ protects the structural integrity of your deck, is easy to install and allows you to create an indoor environment outdoors underneath your deck. You can install ceiling fans, speakers, video, electronics and furniture that will all be safe from the elements.

Stone Deck™
Q: What is StoneDeck™?
A: StoneDeck™ combines premium-quality natural slates, granites and quartzite with a high strength composite backing. This system features a fastening matrix that connects to the deck frame while interlocking all structural panels in place. There is no mortar or grout. The high-strength panels and interlocking matrix form a structure that is flexible, yet strong enough to support 5,000 pounds per square foot.
Q: How big are the tiles and how much do they weigh?
A: Each tile is 16” x 16” and covers 1.78 square feet. A single tile weighs 15 pounds, including the composite backing.
Q: What stone types and colors are available?
A: StoneDeck™ is currently available in three slates: green, gray and multi-color; two granites: tan and white; and a quartzite. Lighter colors will be cooler if your deck is in direct sunlight. As with any natural product, slight color variations are to be expected. Color samples are available upon request.
Q: Can StoneDeck™ be placed over a concrete slab?
A: You can install StoneDeck over a concrete slab but it would be more cost-effective for you to use a stone without our system’s special composite backing.
Q: Is the stone surface slippery?
A: The stones we use have a natural non-skid surface. The surfaces of the slates and quartzite have clefts and the granites are flamed so they are roughened rather than polished.
Q: How does water drain with the StoneDeck™ system?
A: The system’s fastening matrix is designed to allow 1/8” joints between each stone tile. Water drains through the joints and away from the deck surface. The ribbing on the composite backing elevates the stone tile off the “T” or joist. This allows the water to flow away from the deck frame and prevents water damage.
Q: Can StoneDeck™ be used to create a balcony over a living space?
A: StoneDeck™ can be used to create beautiful balconies or raised patios. For these applications it is critical to first install a waterproofing system such as a sloped waterproof membrane. The waterproofing system is independent of the StoneDeck™ system. Installation details for this application can be found in our supplemental installation guide.
Q: What type of framing is used with StoneDeck™?
A: The StoneDeck™ system is designed to work with conventional deck framing. It can be installed over an existing deck frame if it is serviceable. Your installation contractor can help you determine if a new frame is necessary.
Q: Who installs the StoneDeck™ system?
A: StoneDeck™ can be installed by carpenters, deck or dock builders, and landscape contractors. A handy homeowner can also install the system. We can provide detailed installation instructions and guidance.
Q: What is the cost of the StoneDeck™ system?
A: You can expect to pay $15-$18 per square foot for the stone with the composite backing and the fastening matrix. Add approximately $4-$7 per square foot for installation labor. Structural framing may be an additional cost and will depend on the scope of your project.
Q: How does StoneDeck™ compare to a traditional wood deck?
A: StoneDeck™ is a permanent surface that does not have the maintenance and deterioration issues associated with wood surfaces. The long-lasting components can handle the harshest climate conditions.
Q: Should the stone be sealed?
A: We recommend using an impregnating sealer to prevent potential stains from spills and other accidents. Using this type of sealer will not change the stone color. The stone surface should be resealed every four to six years.
Q: Will the stone surface crack over time?
A: The surface of your StoneDeck™ system will not crack. Unlike conventional mortared tile that is rigid, StoneDeck™ is a flexible system that does not require mortar or grout.
Q: Can the stone tiles be cut?
A: The StoneDeck™ tiles, with the composite backing, can be cut using a diamond blade or wet saw.
Q: Can StoneDeck™ slate be used in freeze thaw climates?
A: No. The slate has a tendency to sheer within its sedimentary layers. We recommend that you use any of the Granites or Quartzite colors.
Q: How are the deck edges finished?
A: You can give your StoneDeck™ a finished look by nailing fascia board in place. The stone can also overhang the edge with a piece of stone tile glued beneath as a skirt.

Generally, most dirt and grime can be removed with a high pressure water hose and a deck cleaner that contains oxalic acid, such as a Flood's Deckswood.
Q: How do you clean the mold off of Rhino Deck® Composite decking?
A: For mold/mildew spotting, use Valspar deck cleaner with sodium hypochlorite.
Q: How do I safely remove snow from my Rhino Deck® Composite decking?
A: When shoveling off snow, use a plastic shovel to avoid gouging the finish. Ice and snow will melt off Rhino Deck if calcium chloride or rock salt is applied. Be sure to rinse off calcium chloride or rock salt later to avoid surface residue build-up.
Q: Does Rhino Deck® composite decking expand and contract?
A: Expansion/Contraction: Allow at least 5/16" minimum gap between sides of boards allowing for thermal expansion and water drainage. Gap end joints should be spaced allowing 1/16" for every 20 degree F difference between installation temperature and the hottest average temperature of your geographical area. However, a 1/16" minimum gap should always be present for expansion and drainage. Rhino Deck boards should be at least 45 degrees F at the time of installation. To prevent board ends from splitting, it is important to predrill so that you get a complete clearance hole. Holes need to be predrilled at an angle, which allow for the heads of the screws to be at least 5/8" away from the end of the board. Consult installation guide for drawings.
Q: Can you scratch Rhino Deck® composite decking?
A: Rhino Deck® composite deckingis 50% wood, therefore like traditional wood, care needs to be taken not to scratch or damage the surface. The color of Rhino Deck® is consistent throughout the product; most scratches will fade and tone down in 8-10 weeks, depending on sun exposure.

Edeck® Composite Decking
Q: What is Edeck® composite decking?
A: Edeck® is composite decking made up of High Density Polyethylene (HDPE) polymer, rice hulls as the cellulose and other functional additives.
Q: Why rice hulls?
A: Rice hulls are high in mineral fiber and give Edeck® superior strength and performance enhancements.
Q: In what widths are Edeck® composite decking deck boards available?
A: Edeck® comes in a 6” nominal profile (5 ½” net).
Q: What lengths of composite decking are available?
A: Edeck® is available in 12’, 16’ and 20’ lengths.
Q: Does Edeck® composite decking have a railing system?
A: Yes. Edeck® has a specific rail kit called Classic, available in three colors (Cedar, Redwood and Gull Gray); however, multiple railing options are available in the Xtendex® product line.
Q: What is the difference between Xtendex® and Edeck®?
A: Edeck® is a short line of DIY friendly deck and railing accessories that utilize the Easy 1-2-3 Installation Guide and consumer friendly packaging. Xtendex® is the complete product line, offering hollow as well as solid decking along with additional railing options.
Q: Do you fasten Edeck® composite deckingdown with screws?
A: No. The Quick Clip hidden fastening system provides 50% faster installation. The patented clips are concealed and the surface appearance of the deck is not compromised with fasteners. The “Quick Clip” system also directs expansion and contraction of the deck boards.
Q: Will Edeck® composite decking expand and contract due to temperature changes?
A: All polymer materials will expand and contract more than wood. Rice hulls are added for strength and to minimize expansion. Edeck® will expand and contract 1/8” for every 20 degrees of temperature variation; this must be considered when installing Edeck®.
Q: Does Edeck® composite decking fade?
A: All composite and other building materials fade. Edeck® will fade to a lighter shade within weeks of exposure to ultraviolet rays but will retain the original color hue. Compared to most other composites, Edeck® is more color stable and has UV inhibitors.
Q: Can Edeck® composite decking be recycled?
A: Edeck® uses rice hulls which are an agricultural waste product that would normally be disposed in a landfill. We mix rice hulls with HDPE into a compoun.d which is 100% recyclable for processing. Our polymers are virgin so as to assure consistent quality in the finished deck board.
Q: Does Edeck® composite decking require special maintenance?
A: No. Edeck® requires no water repellents, stain or special cleaners. Edeck® may be cleaned with water and a mild detergent when normal dirt and pollutants coat the surface of Edeck®.
Q: Can I use Edeck® composite decking in high moisture environments?
A: Yes. Because Edeck® uses rice hulls instead of wood fiber, it won’t absorb moisture like wood based products. This means Edeck® swells significantly less than other composites. However, it is advisable to install the deck surface at least 12” above the ground to allow for proper air circulation.
