Once the wood is sawn it must be dried. If this is not
done in the right way, then there is a danger it will
be damaged by fungal rot.
The best time for outdoor drying is in the spring.
The relative humidity of the air is very low and the
wood will dry in a couple of weeks.
Cut some supportive blocks in the length that
corresponds to the width of your pile, ideally larger
pieces, e.g. 5’’5, to raise the wood from the ground,
which should also be dry, level and free of growth.
The spacing should not exceed 1 m and should lie
level and in line with each other.
Cut spacers or drying sticks in the same length as
the supportive blocks.They should be of the same
thickness (1x1’’ or 1x2’’) and dry. (You can get
material for these by making an extra cut when
edging your boards.)
Place the first row of boards on the underlying
surface. The boards are to be of the same thickness
and be positioned a few centimetres apart. Then
place spacers on the boards (in the same positions
as the underlying supportive blocks) before the
next layer is laid. It is important to place the spacers
exactly over each other, to keep the boards from
warping or bending.
The higher you pile the boards, the better pressure
there is on the lower boards. Place roofing of plastic,
metal sheeting or masonite over the top to provide
protection from rain, but leave the sides open. Put a
weight of some sort on the roof to put pressure on
the top boards.
If the wood is to be used for fine joinery, it should
be stored in a heated room for another 3-4 weeks
(longer for thicker dimensions) or be dried in a wood
drying kiln for a perfect result.
It is possible to use undried wood in some
constructions, but it must be kept in mind that the
width and height will shrink 5%. Wood also shrinks
around 0.3% in length, but this can usually be
disregarded. In order to avoid rot, you should not
enclose undried wood in a way that makes it hard
for air to circulate. One further tip: Do not drive two
nails next to each other as the board will probably
crack in the middle when it dries out. Drive one nail
and wait with the second until the wood has dried.
One example of where you should use undried
wood is when building log structures. In such a
situation, a heavy wall is a plus, as is the possibility
that the logs still can be shaped when they are
pressed against each other.
LOGOSOL also has electric
wood drying kilns for
preparation of fine joinery
timber.
