Characteristics:
Specially formulated for application by dipping,
flow-coating or saturation spraying.
Excellent run off.
Excellent absorption and adhesion to timber
A first class foundation for various types of
decorative coatings.
Ensures optimum penetration.
Water thinnable and environmentally friendly.

Properties:
Composition Acrylic / Alkyd-resin
Dispersed in water
Drying Times
Film forming:
Dust dry:
Dry to handle:
Recoatable:
5 to 10 minutes
After approx. 30 min
After approx. 1 hr
After approx. 4 hrs
The above drying times are calculated at 20° C and
65% relative humidity, air speed minimum 0.5
meters per second across the faces of the items and
15 air changes per hour. The drying times can be
greatly reduced by altering the above conditions.
Immediately following application it is advisable
to keep the joinery in still, humid air for at least 10
to 15 minutes. This will reduce the possibility of
the surface drying before run-off, when applying
by saturation.
Practical usage by dipping 120 – 160 ml/m²
Depending on application method and timber
species.
Practical coverage will be affected by factors such
as surface condition, component profile,
application method, temperature etc. To assess
practical spreading rate, a test should be carried
out with the items under the precise working
conditions.
Film thickness:
Not applicable, due to variable absorption of the
timber.
Solid content: 14%
Flash point: > 100° C
Density approx. 1.01
Depending on colour
Minimum application temperature
10° C ( substrate, air and material )
Cleaning of equipment:
Clean equipment immediately after use with clean
cold water followed by a solution of Sikkens
ST830 and fresh lukewarm water. Rinse with clean
fresh water to remove all traces of contamination.
Package:
20 ltr
Application:
Initial Procedure: Stir thoroughly immediately
prior to use.
Method: Dip, flow-coat or saturation spray
Thinning:
Adjust viscosity to 11 to 12 seconds DIN CUP 4 at
20° C, with clean water. Check at least daily and
maintain at this viscosity.
N.B
Dip tanks and flow coaters for application of this
product should be constructed of stainless steel.
Dip tanks should be covered with a tight fitting lid
when not in use.

Processing notes
Basic rules
The wood moisture when using Sikkens systems
should be between 11 % and 15 %.
Paint systems for joinery
1. Fully finished, stable wood frames
Primer
Sikkens Cetol WP 560
Midcoat
Sikkens Cetol WF 950
Finish
Sikkens Cetol WF 950
2. Semi-stable and unstable wooden elements.
If coating semi stable elements be aware of greater
swelling and shrinkage due to moisture. This type
of element must be coated in a thin build system.
The dry film thickness should not exceed 40µm
with unstable and- 80µm Semi-stable elements.
Note:
1. Cover the paint surface during installation
and plastering.
2. Use masking tapes that are compatible with
water based acrylic coatings. Tape should
be removed within two weeks.
3. The finished colour partly depends on the
wood species to which it is applied.
4. Test all products prior to use.
5. The use of flat sawn timber
(crown/arrowhead grain pattern) in high
sunshine areas will significantly reduce the
life span of the coating. Flat sawn timber
(particularly cedar) has a much higher
tendency to distort than quarter sawn
timber. Sorting of quarter sawn timber for
use in high sunshine areas prior to fixing or
manufacture is recommended by BRANZ
in their publication “BRANZ Selecting
Timber Guide (August 2004)”. Coating life
span can be significantly reduced when
used in elevated, seaside or exposed north
facing situations.
