Having
followed preparation and application of base coat in Emulsion,
see Technical Information Sheet, one can achieve a variety of special
effects using Colourwash, Glaze medium. See Technical Information
Sheets.
Preparation:
Seal the surface with diluted Glaze Medium
- one part Glaze Medium two parts water. Allow to dry 3 hours.
Application
Shake Colourwash container well before use.
Pour into a paint tray or open container.
Apply Colourwash to your sealed emulsion surface with a decorators brush.
Using a dragging brush or special effects 'tool' create your desired
effect as detailed below.
A wide range of colours can be made using Colour Concentrate mixed with
Clear Colourwash - See Technical Sheets. Instructions:
Rag Rolling and Bagging using a cotton, lint free cloth or plastic
bag.
Using a decorators brush apply the Colourwash to your surface.
Taking a dry cotton lint free rag, scrunch the rag and roll it across
the surface in roughly random figure of eight shapes, working in an
orderly manner across the surface. As the Colourwash has limited
drying time it is recommended that you work with a partner, (working
on large wall areas can be difficult because you need one person applying
the Colourwash and another creating the effect). When working
on a wall, work from the bottom left up, section by section, across
to the top of the wall, ensuring that your ragging is random, blending
edges in well . When the rag becomes too wet or clogged with Colourwash,
discard and start with a new rag. Leave to dry for at least 3 hours.
Once dry this can be lightly sanded to ensure a uniform effect. A second
coat can be applied in the same manner. Always test on a sample board
first.
This technique can be used with a plastic bag, which moves the glaze
about without absorbing it and creating a deeper texture. Try these
effects on a sample board first.
Dragging using a pure bristle/horse hair dragging brush.
Using a decorators brush, apply Colourwash to your surface -
ensure it is an even coat. (If dragging walls you need a very steady
hand, and a plumb line to ensure the lines are straight. It is recommended
that you work with a partner in order to achieve a professional finish.)
Take your dry dragging brush and place the long bristles flat on to
the painted surface and drag in a straight line downwards, lifting the
brush slightly as you come to the bottom of your wall, door etc. Continue
working in this manner ensuring you always overlap the previous application
to obtain a professional finish. Wipe the dragging brush with a clean,
dry cotton lint free cloth, after each vertical dragging to avoid build
up of glaze. The brush will eventually become clogged - wash and dry
the brush and continue on. Always start at one edge of the surface and
work your way across. Never stop midway through a vertical stroke, this
can lead to streaking and dry patches. Always work from left to right
completing a wall, door etc. without stopping . If you make a mistake,
quickly wipe the surface with a damp cloth and start again!
Sponging using a 'natural' sponge:
Dampen the sponge and then dip into your Colourwash, do not overload
the sponge (take a little each time) and test dabbing on card or paper
first. Once you have established the strength of effect you want, begin
working in a sequence sponging approximately one metre square at a time,
sponge randomly, ensuring you are filling in all the area, avoiding
join lines - fill in gaps missed with a second coat having stood back
and surveyed your work from a distance. Work through from edge to edge
of your wall, door etc. without stopping. Allow each coat to dry at
least 3 hours before applying the next one. You can sponge several colours
over each other.
For sponging 'off' - apply colour with a brush or sponge and then take
a clean damp sponge and dab off -leaving a hint of colour on the surface,
ensure you rinse the sponge to avoid build up. (Use a rag instead of
a sponge if you wish). Once dry you can lightly sand the effect for
a uniform finish.
Note: If using Colourwash in a creative effect on kitchen
cupboards or other high 'wear' areas we suggest you apply a coat of
Glaze Medium, to give a tougher finish, (see Glaze Medium Technical
Information Sheet).
Having followed preparation and application of base coat in Emulsion
see Technical Information Sheet 120 one can apply a variety of special
effects using specialist brushes and tools.
Application:
Add 5ml to 25ml of prepared Binding Agent to 1 litre of Colourwash
making a slow drying glaze for creating special effects.
Shake container before use.
Pour into a paint tray or open container.
Apply with to surface with a brush and create special effects as detailed
below.
For very absorbent surfaces dampen the surface down first with a damp
cloth or sponge. One can also use the semi-transparent Colourwash
mixed with Casein Paint to create special effects. See Special
Effects Sheet.
Instructions:
Rag Rolling and Bagging using a cotton, lint free cloth or plastic
bag.
Using a decorators brush apply the Colourwash mixed with Binding
Agent to approximately 1m square of your surface. Taking a dry cotton
lint free rag, scrunch the rag and roll it across the surface in roughly
random figure of eight shapes, working in an order across the surface.
Always ensure that your sectioned areas blend in well - no streaks or
lines showing. If working on a wall - work from the bottom section by
section and across to the top of the wall. Once dry this can be light
sanded to ensure a uniform effect. When the rag becomes to wet or clogged
with Colourwash, discard and start with a new rag.
This technique can be used with a plastic bag, which moves the glaze
without absorbing, thereby creating a deeper texture. Try these effects
on a sample board first.
Dragging using a pure bristle and horse hair dragging brush.
Using a decorator's brush, apply your Colourwash mixed with Binding
Agent to your surface - ensure it is an even coat.
Take your dragging brush and place flat onto painted surface and drag
in a straight line downwards, lifting the dragging brush slightly as
you come to the bottom of your wall, door etc. Wipe the dragging brush
with a clean dry cotton lint free cloth, after each vertical dragging
to avoid build up of glaze. Ensure that you slightly overlap each vertical
line you drag to create a professional finish.
Always start at one edge of the surface and work your way across. Never
stop midway through a surface, this can lead to dry patches and streaking.
If you make a mistake, quickly wipe the surface with a damp cloth and
start again.
It is recommended that you work with a partner if you are dragging walls
- one applying the glaze and the other dragging through it.
Sponging using a 'natural' sponge:
Dampen the sponge and then dip into your Colourwash mixed with
Binding Agent, do not overload the sponge, take a little each time and
test on a card first. Once you have established the strength of effect
you want, begin working in a sequence, approximately 1m square dabbing
the sponge haphazardly, ensuring you are filling in all the area evenly
- fill in gaps missed after standing back and surveying your work from
a distance.
You can sponge several colours. Allow each colour to dry before applying
the next one.
For sponging 'off' - apply colour with a brush or sponge and then take
a clean damp sponge and dab off -leaving a hint of colour on the surface,
ensure you rinse the sponge to avoid build up. (You can use a rag instead
of a sponge if you wish). Lightly sand the effect for a uniform finish
if desired.
