When it comes to rolling out the walls never ever use a cheap foam roller. Foam rollers never evenly absorb the paint out of the pan and will actually add time to you project and cause more mess. Buy yourself a synthetic professional 3/8 nap roller head for about $6 to $8. Not only will the paint be applied in a smoother fashion you will experience less work and mess.
Now let's proceed to analyzing the center of the composition. There is an optical center in the middle - you will notice that the center of the composition, the major element will never be placed there, otherwise the scene will look artificial. The center of the composition will always be the most striking element, and the rest will just serve to make it more expressive. The artist may use various means to achieve this effect - the color contrasts, light and shade effects, size of objects and distance between them. Secondary elements are depicted with less detail and vigor - they have to bring forward the center, not block it. Notice the way your eyes travel the painting - intuitively you will start at the center and will proceed to the rest of the elements to refine the story.
Years ago, paint was paint. One kind looked, smelled, was applied and eventually dried much like another. Things are different now. Besides oil paints, you can choose from a new set of paints. It'll pay you to know about them. • There are water paints you can use outside. (You clean your brushes under the faucet and use the garden hose to get spatters off the shrubbery.) • There are finishes so tough they withstand even attacks from the neighbors' children. • There are paints that dry so fast you start the second coat as soon as you finish putting on the first. • There are colors in glittering confusion.
Fire-retardant paints do not resist fires completely but its fire-resistance formulation prevents it from fire in spreading fast.
Suppose it rains while you're working? Vinyl paint dries fast - as quickly as 10 to 30 minutes - and will withstand a shower after that time. It takes another 12 hours to "cure," by then forming an exceptionally tough, long-lasting film that stands up well against weather, sun, salt air and factory smoke.
Step four: the key to a finished looking painting is to build it just like a house...and by that I mean layers. Paint it in the reverse order in which the eye sees it to make it three-dimensional. By this I mean paint what's farthest from the eye first, and build layer upon layer towards the eye. In other words, do the background first because it should be the farthest from the eye, then add the objects on top of that, and then add the shadows to complete the look. Ultimately it's common sense. If you paint a bowl of fruit, the bowl and fruit need to sit on top of that background, much as it would in real life.
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.
