Why cut your lawn? Why comb your hair?
Or, if you’re a fellow old enough to remember the last time the Montreal Canadians won the Stanley Cup, why stick to the more conservative boxer short if you’re purchasing swimwear?
Because, in general, things just looks better that way.
So, why stain a wood deck, knowing full well your efforts will only last a year or two before the stain begins to wear and peal, requiring a repeat of the whole process?
Again, because in general, wood looks better when it’s painted or stained.
The alternative to staining or painting, is sitting idle while your decking planks begin to crack, splinter, warp a little, then turn grey over the next few years. Otherwise stated, they get old-looking.
So, to keep your deck looking as new as possible, for as long as possible, there’s no other solution than having to regularly apply stain.
Does applying a stain mean having to sand the wood beforehand? Not necessarily.
There are three different types of finishes to choose from when considering how to protect your cedar or treated-lumber deck. These choices include a clear coat, semi-transparent, and solid (aka opaque) type stains.
Clear coats and semi-transparent stains are traditional favorites because they accentuate the wood grain. The only issue with clears and semis is that sanding will be required every time. That’s because clear coats and semi-transparent stains are practically as thin as water, and as a result, need to sink deeply into the pores of the wood if they’re to effectively grab hold of the surface.
Unfortunately, wood pores can only be opened up by the act of sanding. If you skip the sanding stage, and simply apply a clear or semi type finish over a pre-existing clear or semi-transparent stain, or even bare wood, the liquid will dry on the surface then most likely peel as the year wears on.
Solid stains are my favorite because they don’t require the homeowner having to sand beforehand. The wood surface will need to be washed, in order to eliminate any surface oils and dirt, and primed, if were talking a new wood surface, but not sanded. Solid stains resemble a paint, in that they completely hide the grain, and only highlight the general texture of the wood.
So, if you’ve been used to seeing grain, a solid-colour surface is going to take a little time to get used to. However, telling yourself you’ll never have to sand again is often all the transitional therapy you’ll require.
Regardless of which type of finish you choose, success in staining will require a little help from the weather gods. Deck stains are like fair-weather golfers and only feel truly comfortable when there are white fluffy clouds in the sky, it’s not too hot, or too cold, with absolutely no chance of rain.
As a result, late summer and fall often offer the best windows of staining opportunity.
When do I paint or stain my new treated lumber or cedar deck? Basically, when the wood is dry.
Testing for dry can be done by randomly sealing (on all four sides) a few 4”x4”pieces of saran wrap to the top of various decking planks that will be in the sunlight for at least the next 30 minutes. If after 30 minutes, you see condensation developing on the underside of the plastic, the lumber is still too wet to stain.
Other keys to successful staining?
Buy a good quality brush, wear gloves, and be sure to choose work clothing— if you don’t rinse a stain splatter within the first 10 seconds, that supposedly water-soluble droplet will be there for life.
Other than that, ease the stress on the knees by strapping on a good pair of knee pads (hockey shin pads are a good alternative), take an Advil for the inevitable lower pain to come, turn the radio on, and get at ‘er.
