Chalkboard (From Leftover Materials)

Making a chalkboard is really simple. Heck, you can even buy "chalkboard paint" at almost any hardware store. But why buy chalkboard paint when you can make it yourself? Chalkboard paint can be pricey, and buying paint is bad for the environment, so use what you already have, and come up with something cool! The best thing about it is that it is customizable. There are an infinite amount of color choices and shapes that you can use. Go for it!

Everything that I used was stuff that I already had or salvaged (hence, from leftover materials), with the exception of the non sanded tile grout. You can do the same! Find plywood from some random back lot, at night, without clothes (best camo). Ask relatives for leftover paint, or see if anyone you know has big nuts that they can spare.

Step 1: What you need.

Picture of What you need.
-Plywood (I re-used an old project I had done).
-Chalk.
-4 big bolts and 4 big nuts (as big as you want!).
-Drill and appropriately sized drill bit for your bolts.
-Circular saw.
-Wire.
-Sandpaper.
-Pencil and measuring tape.
-Paint supplies (roller, pan, paint stirrer)
-Non-sanded tile grout (go into Ace and just ask) (not pictured here, but later in the Instructable).
-Leftover flat finish paint, whatever color you have or like (see below).

Now, you may be thinking that there is no way that using paint is a green thing to do, but it is when you consider the following:

- Paint cannot be recycled, it must be used, or dried up and thrown away.
- Many disposal places (dumps) refuse to take any paint cans due to leftover paint hazards. Some dumps even take leftover paint, put it into a new container, and sell it or give it away.
- The minute you bought paint, you commited the eco-crime. Death to you.

Do the responsible thing, and use what you have.

If you do not have any leftover paint, you can still buy paint, but buy low-VOC paint, which is low in "volatile organic compounds" which are pollutants. These paints are low in VOCs, and also low on fumes and odor, so no headache when used!

Good instructable.

You can enhance the photos a lot using some free software as http://photofiltre.en.softonic.com/download.

I recommend it without doubt: it is lightweight, easy to use and FREE.

The following is the result of a 20 seconds work:

Thanks for the tip! I'll put it to use!
I'd highly recommend Picasa. Also free, and incredibly user-friendly in that Google kind of way.

You're right! I just downloaded Picasa, I've always seen it used at school, but never gave it a shot. Very, very, easy!

They use picasa at school. It's on every school account desktop.
Does that software do the same as PhotoShop's AutoLevels to give the result you've shown?
(I've still got a copy of Lviewp1b, which was a free download maybe 10 years ago...)

I don't know PhotoShop features, I know it only by name. PhotoFiltre has Autolevels option, but I don't used that. I adjust gamma, bright and contrast by hand. Maybe Autolevels is better.
I might give PhotoFiltre a go then. Auto' can work very well, but if you have an odd (i.e. unnatural) balance of colours it can do some odd things. L
