If rubber-base paint has been used, the caustic soda treatment may not be effective and it may be necessary to use an organic solvent type of paint remover. Caution: - When using caustic soda or lye, avoid splashing eyes, skin, and clothing. Inside the house is where acrylic shines. It dries faster than other types, and it keeps its color better, without yellowing. One disadvantage: It costs more. Composition Wallboard. Composition wallboard usually presents no particular painting difficulties if the ordinary precautions are observed, such as making certain that the surface is dry and free from grease and oil. The painting procedure for wallboard is the same as for plaster; it requires a priming and sealing coat followed by whatever finishes coats are desired, or may be given one-coat flat or resin-emulsion type paint.
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. Plaster. New dry plaster in good condition, which is to be finished with a paint other than water paint, should be given a coat of primer-sealer and allowed to dry thoroughly before being inspected for uniformity of appearance. Variations in gloss and color differences in the case of tinted primers indicate whether or not the whole surface has been completely sealed. If not, a second coat of primer-sealer should be applied. If only a few "suction spots" are apparent, a second coat over these areas may be sufficient. Fine motor: Beginning to learn to use a pencil before you have developed finger and thumb strength and stability results in a child developing an inefficient pencil grip. When a child has weak thumb stabilisers, he is likely to wrap his thumb around his index finger to try to create greater stability. This makes it very difficult for him to then develop the necessary finger isolation (separate movement of the fingers to give easy, dextrous pencil control). Children who have not yet developed their wrist stability will try to use whole-arm movements to do their drawings and writing and will press very hard. If a child has not developed the bilateral integration (this happens in the brain and is the smooth, efficient communication of the right side of the brain with the left) cutting will be difficult and he will have difficulty writing across his page and reading across a page or school board. Beginning to use a pencil too soon therefore inhibits learning in a formal class setting, rather than helping it. 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.
