Masonry Walls and Ceilings. Interior masonry walls and ceilings above grade may, in general, be painted in much the same manner as plaster surfaces. Here again, it is necessary to allow adequate time for the masonry to dry before applying paint and, in addition, attention should be given to the preparation of the surface. When decorating a wall containing Portland cement (concrete, for example), it is essential to take precautions against the attack of alkali. For this purpose, alkali-resistant primers such as rubber-base paints may be used when oil paints are to follow.
Fire-retardant paints do not resist fires completely but its fire-resistance formulation prevents it from fire in spreading fast.
Intensity refers to a colors brightness or saturation. Intensity refers to how pure a color is. For instance, if you were to use cadmium red straight from the tube, it would have a high intensity. If you were to mix it with another color however, its intensity would be diminished.
Purple is the most contradicting color, to start at least because it consists of two antagonists: hot red and cold blue, ice and fire. It is the most mysterious color. It was the last color to emerge in art. Purple has a lot of other shades that are less rich and more lightened and muted: starting from light-lilac and going up to ashy gray-purple, which can give the interior a certain style and exquisiteness.
Five categories are used to describe VOC content. For guidance, a minimal VOC content is up to 0.29 per cent, whereas a very high VOC content is above 50 per cent. All brands have, where necessary, reformulated their ranges to give minimal VOC content.
Satin or silk - Water-based vinyl or acrylic paint for walls in high-wear areas, such as hallways and kitchens. A satin finish will be slightly shinier than silk.
Reading: To read well, a child needs to have developed the ability to notice the separate sounds in words. He also needs to be able to recognise similarities and differences in how words sound (eg: rhyming words or words that sound the same but have different meanings). Trying to learn these in a formal setting is daunting and removes the chance of the child feeling that he can take ownership of words; instead he feels that words are foist upon him and outside of his control.
