Decoupage: Step by step example

Extracted from:
http://www.artekjara.it


Step by step example: Decoupage - Kjara
I report here step by step work sequence for basic decoupage technique . I used a round tray of plywood on which I glued a print of a magnolia flower.
How to prepare the tray:: Vinyl glue, which works as woodfiller and white water paint.
Acrylic colours: Lefranc, Maimeri and Deka
Dimensions of the tray: diameter 30 cm
Of course you can click on the pictures to see them enlarged.

The wooden tray

I used a tray of plywood with the border made
of wood paste.
First of all this surface must be treated with a
woodfiller: vinyl glue watered down is perfect.
Brush all on the surface, the border and the
back too. This coat will make the waterpaint
adhere to the surface well.

Water painting

Now I brush a coat of white water paint, the
one used for painting walls is perfect. Once
it has dried I smooth the surface using abrasive
paper. On this coat I am going to paint with
acrylic colours.

The background colour

To make the colour of the background I use
green and white acrylic colours and Siennas.
Siennas are colour powder calledpigmentic.
I use varnish, as medium, in order to mix the
colours I have created with industrial colours.

I brush the colour on the surface and while it is
still wet I shade it using a sponge so as to
eliminate the brush marks.

I let it dry, then I lay some more coats of colour
using this technique in order to make the surface
uniform.
I use a darker tone of green for the border of
the tray.

Scraps of paper

I've choosen a print of a magnolia flower for the
decoration, so I cut it out using manicure scissor.
It's important to follow the side of the figure perfectly.

Water, glue and a soft brush...

Mix in a pot vinyl glue and water in order to obtain the
consistency of yoghurt, prepare a paper towel to dry the
scraps of paper and a soft brush to spread the glue.

Arranging

Before you proceed gluing the scrap, you'd better
arrange the decoration of the flower placing the
flower, the petals and the leaves so that everything is
balanced.

Wetting

Before brushing the glue on the back of the scrape,
I wet it in a basin filled with water. This way the
paper get softer, will better receive the glue and
will lie down on the surface easier, thus avoiding
air bubble.

Drying

Using a paper towel I dry the wet scrap being careful
not to damage the paper, which is still wet so it's fragile.

Gluing

I lay the wet and dried paper scrap on an aluminium
sheet, then I spread the glue onto it using a soft brush.
I use aluminium sheet as a support to spread the glue,
because this way the scrap of paper won't stick on it.
Whereas if I used other materials, such as newspaper
sheet, the scrap would stick on it, and I wouldn't be
able to detach it.

Laying the scrap

Using the brush I detach the scrap of paper filled with
glue and I lay it on the surface in the center of the tray.

Brushing the glue

I brush the glue on the scrap in order to flatten it on
the surface and to eliminate air bubble.

Air bubbles

Using my fingers covered with glue I press on the
scrap starting from the centre toward the side, in
order to push the air bubbles out.

Brushing with the glue

Once the gluing is over, then I brush the glue all
over the surface, in order to protect the scraps.

Varnishing

Once the glue has perfectly dried, then I can brush
the first coat of varnish. It's possible that while doing
this some white spots might appear on the surface.
Never mind, once the varnish has dried up it will
turn transparent again. It's necessary to brush
several coats of varnish to eliminate the difference in
level between the background and the scrap of paper.
I suggest to give almost ten coats of varnish, of course
waiting for the last coat to dry before giving a new one,
change the verso in which you brush for each coat, for
example the first coat brush horizontally, the second
coat vertically, then horizontally again...

Smoothing the surface with abrasive 

paper

Once the ten coats of varnish have dried up, to smooth the
surface, it's better to use an abrasive paper on it. I start with
abrasive paper of middle grain then I dust it off with a cloth,
I give it another coat or two of varnish, wait it to dry, then I
use abrasive paper of fine grain, and give it another coat of
varnish... and so on until I'm proud of the result.

Over

The work is over. I can give a coat of wax, then polish it,
wax used for parquet is perfect.
