Piece of advice
•
Always read the instructions on the paint
thoroughly before you begin painting
•
All surfaces and rebates must be dry and
free of dirt before you begin
•
Weatherstrips and movable parts of hinges
and handles should not be painted. Please
note that the weatherstrip is mounted
loosely in a groove, making it easy to rem-
ove before you paint and to remount when
the paint is dry
•
DVC’s guarantee label must not be painted
•
Use masking tape to facilitate painting
along edges
•
Always use a good brush with a proper
width.
•
Always paint wet in wet to avoid overlaps.
•
Always have a cloth and plastic bag at hand.
Use the cloth to dry off incorrect strokes
and drips from the brush. Use the plastic
bag to wrap around your brush if your work
is interrupted for a short period of time
•
Remember that hinged sashes must not be
closed before the paint is completely dry.
We advise you not to use pure
plastic paints as the wea-
therstrips between frame
and sash may contain syn-
thetic rubbers, which have a
tendency to stick to such sur-
faces.
Expected outcome of industrially surface
treated timber elements
Manufacturers associated with DVC use sur-
face treatment on wood elements which, as
a minimum, provide the following results:

All surfaces have been treated, but a uni-

Supplementary description of outcome
Wood is a natural material and therefore of-
ten very heterogeneous. Variations in struc-
ture and gloss, star shakes and other variati-
ons are normal such as irregularities around
knots where partial peeling, blistering and
