Sealing a Deck with Deck Sealant
How to Seal a Deck Properly with a Clear
By: Mark J. Donovan
A deck is an extension of your home. It is a living space that
enables us to enjoy the outdoors without having to be literally standing
or sitting in the yard. It is the ideal space to have a barbeque or just
sit back, relax, and read a book and enjoy the comfortable outside
temperatures on a warm summer day.
A deck takes a lot of abuse from natureís elements, however. Rain, snow,
ice, extreme hot and cold temperatures, and ultra-violet light from the
sun can destroy a deck in less time than you think, if it is not
maintained properly and regularly.
One of the chief ways to protect a deck from all of natureís elements is
to seal your deck every one or two years. Sealing a deck not only protects
it from the elements, it also helps to preserveís the natural beauty
associated with any wood deck.
Described below are instructions on sealing a deck so that your wood deck
will last for years to come.
Best Time to Seal a Deck
In order to maintain the natural beauty of my wood deck I typically seal it
every year or two. Also, because I live in New England, I find sealing the
deck in late summer or early fall also makes the most sense. By sealing it
during this time of the year I prepare it for the upcoming winter months
which are the most severe and detrimental to wood decking. Snow sitting on a
wood deck can slowly eat away at the wood due to the acidity of the water
content in the snow. Thus by sealing the deck just prior to winter Iím
giving the wood decking a layer of protection to combat against the acidic
snow and water.
If you live in a warmer climate, then I recommend sealing your deck in late
spring to protect it from the intense heat and ultra-violet sunlight of the
Preparing Deck for Sealing
The first step in sealing a deck is to remove all the furniture and
other objects from it and give it a thorough cleaning. You can clean the
deck with any of the commercially available deck cleaners and/or you can
clean the deck with a power washer. However, if you choose to use a
power washer take great care not to destroy the wood decking with it.
The wood can be severely and irreparably damaged by a power washer. If
you decide to use a pressure washer to clean your deck, use the lowest
pressure nozzle setting and keep the nozzle head at least a foot away
from the wood decking and railings while washing with it.
If there is pine pitch on your deck then you may also need to use a
stiff bristle brush to loosen it up and remove it.
After the deck has been cleaned allow it to thoroughly dry for 24 to 48
hours. Do not seal a deck with the wood still damp. If you do, the deck
sealant wonít absorb well into the wood and will end up flaking off and
overall making your deck look like an ugly mess.
Just prior to sealing your deck give it a once over with a broom or leaf
blower to ensure it is free of any dirt or debris.
Sealing your Deck
Seal your deck when the temperatures are above 50oF and there is no sign
of rain in the forecast for at least the next 24 hours. If it rains just
after sealing the deck, again the sealant wonít absorb properly into the
wood, and youíll have a peeling mess that will only be able to be
removed by sanding the entire deck.

If you have a relatively small deck, apply the sealer with a brush.
If you have a large deck, use a roller to initially apply the deck
sealer. However, I find that the sealing penetrates best when applied
with a brush. Thus, if you do use a roller to apply the deck sealer to
the decking boards, apply it in small sections and follow right behind
with a brush to work the deck sealer into the wood for maximum
Typically only one coast of deck sealant is necessary. After applying
the deck sealer wait 24 to 48 hours to walk on the deck and return the
furniture to it. If the humidity is high I recommend waiting 48 hours to
ensure it is fully dry. If the deck is tacky at all, wait another 24
hours before using it.
