Primer paints may be oil- or water-based and are used to seal unpainted surfaces to prevent covering coats of paint soaking in. The appropriate type of primer should be used for the surface being painted - wood, metal, plaster or tiles. There are some 'all purpose primers' available which are designed for two or more of these surfaces.
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.
There is still no standard labelling scheme for paint. The blue globe label, pioneered by B&Q, led to VOC reduction on the mass market and has been adopted by other brands, while the European Ecolabel, recognised in 15 EU member states, looks like a flower and appears on brands such as Earthborn. Germany also has a Blue Angel label and there is a green Nordic Swan as well. You will find more detailed information on most of the paint company's websites, as well as a wealth of practical and design advice.
Following a European directive, the British paint industry has reduced VOCs in two stages, the second of which came into force in January last year.
Cement-water paints are best suited for application to basement walls which are damp as a result of leakage or condensation. To apply these paints, the same procedure should be followed as is described here for painting exterior masonry walls.
So how does a paint company accomplish this color hypnosis of potential customers? Well, it starts with the sample card. Have you ever noticed how the brightest, most saturated color sample cards are always the first row you see in a paint display? Well you guessed it... paint companies are playing with a loaded deck (of sample cards, that is)!
When you plan with split complementary colors, you begin with a single reference color. Next, choose a color from either edge of the complementary color and use it. While the complementary color scheme is a little more obvious, this scheme can fail totally if you just use paler versions of your warm colors. By the same token, picking a a warm undertone for the main contrasting color and combining it with two cool tones will showcase the warm tone.
