With all the terrific choices of composite decking available in today’s market, why would any homeowner install treated lumber or cedar on their decks?
Although it’s been suggested to avoid using uncovered wood products outside, especially relating to porch posts and railing systems, real wood decking still holds some advantages over the solid PVC or composite decking alternatives.
However, the “holds some advantages” statement will have to be qualified by referencing the fact composites still have some challenges, or product glitches that will need to be ironed out, in order for the choice of composite decking over real wood to eventually be considered a no-brainer.
Challenge No. 1: price.
Although aluminum and vinyl railing systems have fallen in price, due to improvements in manufacturing and larger-scale production, the costs of composite decking have steadily increased. Unlike aluminum and vinyl railing components, which have been around for decades, composite decking is relatively new, and has seen lots of improvements from those early generation composites that often swelled and developed mould.
Today’s solid PVC, or composite/PVC-wrapped products have evolved considerably from those early years, with swelling, shrinking, expansion, and mould being non-issues. However, this road to composite decking success has of course come at a price for the manufacturer, with these research and development costs filtering down to the eventual consumer.
Is composite decking done evolving? Not quite yet.
Although the recipe for making a composite or solid PVC decking product is pretty well understood, with developments in sheen, texture, and colour variation, every manufacturer’s goal is to make their composite as realistic looking as possible. The cost to purchasing composite decking is not likely to fall anytime soon.
So, although aluminum and vinyl railing systems stand at an affordable two-to-three times the price of real wood, composite decking remains two-to-four times the price of cedar, and four-to-eight times the price of treated lumber. As a result, there’s still hesitancy on the part of the consumer in purchasing such a premium deck product, with further improvements regarding the costs of production to be made on the manufacturing end.
Challenge No. 2: temperature.
Essentially, in severe heat and/or direct sunlight, composite decking, regardless of colour or texture, gets too hot to walk on in bare feet. Real wood decking, under the duress of heat or direct sunlight, remains relatively comfortable to bare feet. So, regardless of composite decking’s many attributes, on some levels it may never outperform Mother Nature.
So, how does the homeowner deal with wood decking’s biggest challenge, which is of course maintenance? Is doing nothing to your wood deck an option? Yes, but a really lousy one.
Without some type of protection, a wood surface will warp, crack, develop slivers, and essentially look horrible.
Now, if your backyard is littered with dog poop, a 1970 Pontiac Parisienne on blocks, and a few garden gnomes scattered about, then a greying, decaying deck would provide the perfect centerpiece to such a backyard world of death and misery.
Luckily, success in owning a great looking wood deck that’ll demand only minimal maintenance, will require invoking these procedures.
One, sand both sides and the two edges of each plank with an 80-grit sandpaper.
Next, seal the underside of the planks with a clear waterproofing product.
Three, and most importantly, refrain from surface screwing the decking planks. Choose either the ‘Camo’ installation tool, which is a procedure that strategically guides the camo screw into the edges of the decking plank, or fasten the decking planks from underneath by first installing deck brackets, which are perforated steel strips that get fixed along the edge of each joist. Surface screws are to be avoided because they provide a direct route for water and moisture to enter into the core of the lumber. When this core water freezes, cracks, splitting, and splintering are the results.
Conversely, a sanded wood surface, when sealed, should last for years before needing a further coat. Next week, more on real wood decking.
