The paints may be applied by brush or spray; the small spray attachment for vacuum cleaners is very convenient, especially for painting radiators.
Matt - Describes paints that give a flat, non-reflective finish. It is ideal for walls and ceilings that are not perfectly smooth.
Alkyd is an old interior paint made newly popular by a change in solvent - a super-refined petroleum chemical that has almost no odor. It is not a water paint. You thin it and clean brushes with mineral spirits or turpentine, or, if you want to retain the odorless feature, with the new odorless solvent. (Ask the paint-store man for just that, odorless solvent).
Paint Selection. Most paints are purchased ready-mixed but, in their selection, consideration should be given to the fact that surfaces vary in their adaptability to paint and atmospheric or other conditions having an adverse effect on paint performance. In addition to the normal weathering action of sun and rain, outside house paints are sometimes exposed to other attacking elements, such as corrosive fumes from factories or excessive amounts of wind-driven dust.
Once you figure out which position is prime and which position is spray, place the valve in the prime position and grab the primer hose. Point the primer hose in the empty bucket near the top and at an aproxx.45 degree angle from the side (the reason for this is that there is likely to be pressure still built up in the airless and when you first switch on the airless to prime it, paint will likely burst out of the primer hose and you don't want to have it go everywhere). Now turn the airless paint sprayer on and you will see that the airless is sucking up the new paint and pumping out the primer hose. At first you will typically see a cleaning solution come out followed by your paint. When you see your paint coming out switch over the primer valve to the other position and you will see the airless pumping paint into the main hose.
Play develops through fairly standard stages and each stage is a necessary precursor for the next. These stages provide the key foundations for our children to become well-prepared to cope with the physical, cognitive, emotional and social demands of formal schooling. Rushing children through the different stages, does not mean they achieve school readiness quicker; it means they lose out on the developmental window to develop strongest foundations.
Usually on exposed air ducts of galvanized metal a primer coat of zinc dust-zinc oxide paint is used, before the finish coat is applied.
