Before you begin:
BioWash Wood Wash or a
similar sodium hydroxide solution for
cleaning wood decks, releases the dead wood fibers from the
healthy wood surface. These products normally work on contact
and can easily be applied with a garden sprayer or low power pressure
washer. Next, use a hose and a scrub broom, or again the low
power pressure washer, to clean and remove the old degenerated wood
fibers from the surface of the deck. Note: If you are
redoing a previously coated deck you may need a stronger solution
to remove the old coating such as StripXL or similar wood stain
stripper as some coating cannot be removed simply by cleaning.
As decks weather they turn a grey
color. This is the results of the Sun’s UV rays. This grey
looking surface is actually nature’s way of protecting the wood
underneath from harm. Sort of like how a suntan protects
your skin in the summer months. Unfortunately once grayed,
the deck’s appearance does not look as nice as a good tan.
Hence BioWash Natural Deck Oil™ was born. It gives great UV
protection (except clear) while allowing a beautiful wood tone (or Suntan) to be
You're almost ready to coat:
The next step is to apply
Stain Prep / Mill Glaze Away. BioWash Natural Deck Oil™
is specifically engineered to work best with an alkaline substrate
(pH between 7 to 10). As wood ages it naturally moves towards
an acidic pH. Therefore, Stain Prep will adjust the pH level
and prepare the wood to fully accept BioWash Natural Deck Oil giving
you years of both a great look and protection. Apply
Stain Prep and then rinse with plenty of water. Let the wood dry
for at least two to three hours or until dry-to-touch.
Apply BioWash Natural Deck Oil™ within 12 hours of the Stain Prep
If your wood is newer or never
been coated you will have what is known as Mill Crush or Glaze on
the surface. This condition will inhibit the wood from fully
absorbing a coating. Again Stain Prep / Mill Glaze Away
will open up the pores of the wood for saturation. This product
is easily applied and rinsed per instruction with the same garden
sprayer as before.
Now that your deck has been properly cleaned and prepped, you are
ready for application of the BioWash Natural Deck Oil™ . This
will require two coats for maximum protection and appearance.
One coat for maintenance coating. Apply out of direct sunlight
and on a cool surface above 40 F (5 C). If the surface is above
100 F (38 C) do not apply. Avoid application of product when
the daily low is below 40°F (5°C) or rain is in the immediate forecast.
Stir BioWash Natural Deck Oil™ well prior to use and stain pickets
or uprights first! Utilize any BioWash Natural Deck Oil™ that
may run down the pickets or uprights to work into your deck application.
Always beginning with boards near those pickets so that the product
does not pool near the bottom.
By Brush: First Coat
application will use the largest amount of product as it is more
readily absorbed by direct contact with the wood surface. Brushing
is the preferred method of application but can often be difficult
on your back. If this is a concern you may want to consider
using the Roller method specified below. Otherwise apply at
least two coats of Natural Deck Oil™ with a 6 inch combination nylon/polyester
paintbrush. Wait about two hours or until first coat is dry-to-touch
to apply next coat.
Apply generously with a medium roller two
or three boards at a time, completing a full length of boards each
time before moving to the next set. Use an 18 to 24 inch wide
soft bristle push broom to work the coating into the wood fibers
before moving to the next set of boards. The push broom doubles
as the brush you did not use above, merely a wider and longer version.
You will want to avoid the pooling of material and uneven application
which is often associated with rolling. A rule of thumb is
to apply product on 3 or 4 boards for the full length of the board
then come back and work the product in. This helps to better
control the product. The look is quite nice and not to difficult
with a little practice. A little help from your spouse, relative
or neighbor will make this go quickly. By using this procedure
you may avoid so-called Lap and/or Line Marks.
If spraying, saturate a small surface area
and then immediately back-brush to promote saturation of the wood.
2nd Coat Application:
After you finish the whole deck take a break for about an hour or
two. Then begin at the same spot as before and repeat
the entire application. The second coat will absorb much less
of the product and the process will move along at a quicker rate.
It will look great when finished but will look even better a day
or two later after the product has had ample time to cure.
A complete cure of the coating for a walked on surfaces is 48 hours
at 65°F (12°C) and 50% humidity.
Time to clean up:
Tools clean up with water. Dried overspray and/or spills can
be cleaned using RemovALL 400 or BioWash
