WOOD REPAIR
Easy - Safe - Quick - Perfect!

The Importance
of Wood Repair
Wood is a product of nature. As it grows,
each tree is shaped in a unique way by its environment.
You could even say that there are
artistic elements in every tree- a compilation
of different shapes and colors. You never
know what is inside until you cut it open.
Many consumers enjoy the variety in grain and color
they get from filling their space with wooden objects.
While the unique character of each piece of wood is
beloved by consumers, it can be a challenge for wood
shops to process. Preparing your stock can be a costly
affair if it is necessary to throw away every piece of
wood that contains a knot or a bigger scratch. Knots
and scratches give the wood character and can be
beautiful to preserve when handled correctly.
Every wood shop needs the right products when
doing wood repair. The right solution must be flexible,
durable, and match the color of the wood. This is
where we can help!
We specialize in wood repair products, and offer a
range of solutions for repairing all sorts of wood for
all sorts of purposes. We can assist you in finding the
solution to fit the specific needs of what you or your
company are making.

Knot Filler
The best solution for repairing wood.
It is flexible, strong and durable at the
same time.
Knot Filler is the best solution when repairing
wood. It is very easy to use, and the result is
great whether you are fixing a scratch, damage
or a big knot. You can even use the Knot Filler
on the edge and corner of the wood piece. Knot
Filler is suitable for all sorts of wooden objects
such as flooring, furniture, windows etc. We
even see great advantages when using this
product as formwork filler.
The advantages of using the Knot Filler are
many. First of all, it’s the impeccable result.
When using the correct color, the repair will be
very hard to spot once finishing treatment has
been applied. The filler works with oil, lacquer,
paint - even stain.
Finding the right color is easy. We have a variety
of great colors to match most wood species.
Our colours are guided by industry trends and
requests from the woodworkers who love our
filler. For example, right now, many of our clients
prefer to highlight a knot instead of hiding it,
and use a significantly darker fill color than their
wood stock.

How does Knot Filler work?
Knot Filler rods come as 30cm sticks with a diameter of 12mm. It is easily applied with the
RKF100000 gun, but most glue guns with an adjustable temperature setting will work.
You simply use the gun to fill the void with hot filler, apply a heat sink to cool the liquid filler
and solidify the repair, and cut/sand off excess filler - done! Ready to be cut or finished.
The tools we recommend when using Knot Filler are designed specifically for making
perfect repairs. They are also made to resist high temperatures from hot liquid filler (see
page 6).

Granulate
Many larger, industrial-type production facilities have contacted us about largescale
Knot Filler applications. This interest prompted us to develop a form of Knot
Filler that can be applied in high volume. This granulate form has the same material
properties as our Knot Filler rods, and is mostly used at large industrial sites where
output and quantities are high.
Specialize equipment is required to be used for the
Knot Filler granulate format. Contact us for more

B2 Powder Filler
If you are searching for a wood paste filler that can be applied
by hand, then look no further! Powder Filler is the solution
for you.
One of our more specific repair products is the Powder Filler. Just
add water, stir and you are ready to begin. It is possible to add color
pigment or stain to the mixture to obtain just the right color.
Powder Filler is suitable for repairs and knots with depths up to 15
mm and accepts stain, lacquer, oil, paint etc.
Properly stored dry powder has no expiry date. Mix only what is
needed at the time, and re-mix when it is necessary. This way you
have fresh filler all the time, and there will be no waste.

Need even more resistant filler?
To meet the demands of extreme manufacturing procedures we
offer a special hardener that can be added to the mixture. This
ensures that the filler will remain in the wood even after hard
brushing which means it is perfect for repairing hardwood flooring.
The hardener shortens the drying time and makes the repaired
area highly resistant to being damaged again.

Both powder and hardener are green/environment friendly and
therefore safe to use.
