I decided that the laptop I had been given looked a little plain, but it did have a nice flat surface so i thought I would paint it.
what you will need:
various colored paints, I used acrylic paints but you could use spray paint
Compressor and airbrush, if you're using acrylic paints
Clear Lacquer , the stuff you use on cars is fine
Small Paint brush
Paper and pencil
Transparency sheet for OHPs
Step 1: Get your design together
you need to think about what you want to put on it, I wanted to stencil the grim reaper, I copied a picture i saw on the net on to a sheet of plain paper.
next i put a transparency over the top and traced round the outside of the design using the OHP pen, use the bulldog clip to hold the transparency in place while your tracing the original design.
then using a hobby knife i cut round the traced areas carefully and pulled out the bits I don't want.
I already I have an idea for the background which will be done freehand
Step 2: Prep the laptop and start the background
Show All 9 Items
now you need to prep your laptop to be painted.
mask around the laptop and any parts you don't want painted such as lights
once that's done, wipe over the laptop to make sure it's a clean surface without grease or finger prints, I used a screen wipe but you could use a wipe from a fast food place.
you will need somewhere to spray I use a cardboard box with one end cut off which works really well.
to start the background mix up the main color you want to use, mine is plain white, I mixed up normal acrylic with a little water to make it almost the consistency of milk then put it in the airbrush.
I sprayed just inside the edge as I wanted to create a faded effect to the black.
then i used the hair dryer to dry the paint before i start the next layer
I then added a little yellow to the original mix of white paint, then sprayed that on the white making it deliberately patchy, the color was only slight almost magnolia.
hair dryer again before doing the next layer
I then added more yellow and again sprayed it deliberately patchy.
hair dryer again to dry the background.
and that's my basic background done.
Step 3: Background detail
Now I add the background details, I've been watching a ton of Dexter so I wanted a kind of blood cast off theme so I mixed up some red with a little brown to create the blood color, added a little water to make it the consistency of blood, so thicker than before.
at this point you might want to practice on a piece of paper
using a small brush i flicked paint over the laptop to create cast off patterns, using different amounts of paint on the brush created different effects so it's worth practicing first,
then I painted a thick layer on to my hand making sure it was a little patchy then placed my hand a couple of times on to the laptop
then used the hair dryer to dry the blood effect
Step 4: Adding the stencil
now it's time for the stencil, take a piece of paper and fold it alternate ways this will make sure the stencil can be picked up once it's been coated with spray mount.
at this stage make sure you cover everything with newspaper, spray mount is really sticky.
put your stencil on the folded paper then spray it with a light coat of spray mount
place it carefully on the laptop making sure that all the detailed bits stick
stick paper round the edges so you don't spray bits you don't want to
i used black car paint for this bit mainly due to laziness on my part, I sprayed a decent coat at about 20cm distance.
I wanted a few minutes for the paint to be touch dry then carefully removed the stencil
Step 5: Preserving the design
Now we have the design and the paint is dry on the stencil design it's time to protect it with a lot of coats of Lacquer without it the design will just scratch off.
using a clear Lacquer, i used car Lacquer, spray a light coat at a distance of about 20cm
use the hair dryer to dry the Lacquer, this will Bake it on there just like they do when they spray cars professionally
now all you have to do is repeat these 2 steps about 10 times, and I'm not kidding here, the more the better you want a nice thick coat as this will be the only protection of the design.
once you done the last coat you need to leave it for at least 24 hours to make sure the Lacquer is properly cured.
and thats it, all done, remove the masking tape and its ready to use.
