AP5 |
AP5 is the contact fungicide used on
freshly peeled or sawn logs to control sap
stain and begin the preservation process.
AP5 is liberally applied to all cut and
exposed surfaces, as soon as possible after
peeling, sawing, notching etc. AP5 is used to
best effect when the moisture content
exceeds 25%.
Always add CONCENTRATE to WATER.
AP5 can be applied by brush, spray, roller
or by dipping |
Spray Application
6
m2/litre minimum
Brush Application
Other surfaces
Dipping
60 minute dip/soak
5 day dip/soak |
Use knapsack, garden or similar airless type
spray, and spray to saturation.
Dilution: 4 parts clean water to 1 part AP5
Use
neat (undiluted) on cut joints,
notches etc.
Dilution: 4 parts clean water to 1 part AP5
Use plastic lined or stainless steel tanks
Dilution: 20 parts clean water to 1 part AP5
Dilution: 50 parts clean water to 1 part AP5 |

CD50LOG
|
CD50LOG
is then applied at a rate of 5
m2
per litre, with
1 application (minimum) per 100mm diameter of log,
when moisture percentage is suitable. i.e. 4 coats for
a 400mm diameter log.
If newly felled logs are to be treated, apply once
the surface has started to dry, leaving the ends or
preferably the interior untreated to allow the
moisture to be driven out. This will slow drying and
help prevent checking on log ends.
Apply the calculated number of applications
liberally, about a week apart. This allows time for
CD50LOG to migrate through the fibres as the timber
eliminates moisture.
If you are intending to use a colourtone in the
CD50, it is recommended to use the colourtone also
in the CD50Log applications as colour retention will
be increased. |
CD50
|
CD50
is used for ongoing protection of the logs. The CD50
gives superior water repellency and continues the
preservation process.
Apply 2 coats of CD50 at least 4 weeks apart at a
rate of 5-7
m2 per litre, after the CD50Log
program has been completed.
CD50 is then used thereafter at a minimum of one
application every 3 years
