Rubber-base paints, which dry to a hard semi-gloss finish, may be used on concrete floors below grade, providing the floor is not continually damp from seepage and condensation.
The paints may be applied by brush or spray; the small spray attachment for vacuum cleaners is very convenient, especially for painting radiators.
Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!)
THE BRUSHWORK. Depending on the art movement and personal peculiarities of the artist, the brushwork can range from delicate and almost invisible to rough and plastic.
STENCILING. You may want designs on the walls, or perhaps even on floors and ceilings, in some of the rooms or hallway. You may buy or make your own stencils, which should be on heavy paper, stencil board, plastic, or metal. Avoid stencils made of lightweight paper which will get soaked when touched by wet paint. Your paint dealer will suggest the best paint for you to use, as it will depend a great deal on the surface over which you want to put the stenciled designs. Generally a heavy paint is used, so that it will not spread under the stencil while you are applying it.
The lite version of Galkyd is simply thinner. I use it more than the other. I love it. Paintings I did 16 years ago using Galkyds look as pristine as the day I painted them. You'll also need a canvas and some paint. I buy a tube of red, green, blue, purple, yellow, brown, white and black. I prefer what's called Ivory Black and a soft mixing white as you'll add white to a lot of different colors to make lighter versions. From these basic colors you can make any exotic color by mixing them in combination's. Be creative and experiment. And don't be afraid of color, because color is the most popular in museums! The bright paintings are historically the crowd favorites. As for color variety from these basic colors, mix red and white to make pink, mix yellow with green to make lime green, white with blue to make light blue, white with black to make gray, etc. Use your common sense and play with it! You'll also need pencils, an eraser and some Turpentine or Turpentine substitute. Keep your brushes soaking in it in a plastic cup to keep them clean and ready for your next color choice.... and to keep them from drying out.
Cutting Down on Paint Chemicals. Everyone knows the nasty smell of paint drying - worse with oil-based paints, but also noticeable with vinyl emulsions. This is caused by paint solvents containing VOCs. They are proven health risks, and can cause allergies, headaches and breathing problems and irritate eyes, nose and throat. They are also an environmental hazard.
