Wood Walls and Trim. New interior walls and wood trim should be smoothed with sand-paper and dusted before painting or varnishing. To preserve the grain of the wood, the surface may be rubbed with linseed oil, varnished or shellacked, and waxed. If an opaque finish is desired, semi-gloss paint thinned with 1 pint of turpen-tine per gallon of paint or the primer-sealer previously described for walls may be used as a priming coat on wood. One or two coats of semi-gloss paint should then be applied over the thoroughly dry prime coat, or if a full-gloss finish is desired, the last coat should be a high-gloss enamel.
WALL PAINTING TIPS. · Paint around the trim first, including edging around the ceiling. · When painting with a gloss finish, make the final brush strokes away from the light source of the room. The tiny ridges that a brush leaves won't be as pronounced. Use the same "wet to dry" method of painting.
Basically what you're looking for is a good, solid foundation of existing paint that is stable and still strongly bonded to the car. Many times an original factory paint job, even after decades will meet these criteria.
If you decide to do your own body work discuss it with the paint shop first. They'll probably have recommendations on the type of primer you use. Some brands will be more compatible with their primers or color coats. The rule of thumb is to stay within the same brand of paint, both for prep and color. Even the cheapest paint shops typically use a brand name on their intermediate and higher paint jobs. Find out what it is and use the same brand as your primer coat. This will ensure you don't create adhesion problems for yourself down the road.
Cold water paints of the casein type may be applied either directly to a plastered surface, or the surface may be first given a coat of primer-sealer to equalize uneven suction effects. The same is true of resin-emulsion paints, with the recommendations of the manufacturer of the product being given preference in case of doubt. Since resin-emulsion paints usually contain some oil in the binder, they should ordinarily be applied only to plaster which has dried thoroughly.
The leading brands now flag up paints with lower VOCs and produce paints that are virtually odour-free - the Breatheasy range by Crown is one example. Most leading brands now produce high-quality water-based acrylic paints which outperform the older technologies of vinyl and oils.
Have plenty of newspaper around. After you clean your brushes wrap them in a plastic bag.
