You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better.
A Gloss paint is easy to clean and resists scuffs better. This is ideal for rooms that are constantly used. Most gloss paints are best recommended to use on woodworks, baseboards, kitchen and bathroom walls, doorjambs, and window casings. The downside of using gloss paints, however, is the noticeable imperfections in the wall surface.
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.
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.
Masonry paints come in a wide variety of finishes, from textured to ultra-smooth. Opt for a texture if you need to disguise fine surface cracks. If you favour traditional finishes, then consider limewash, which is available from specialists such as Francesca's Lime Wash. The beauty of this paint is that it will mellow and weather with time. However, do check with the supplier first to ensure that the surface is suitable for this finish.
If you have large holes or cracks in a wall purchase a small can of vinyl repair paste. The reason I prefer it over regular wall Spackle is that after it dries it is much harder and sands easily. You can even use it for minor wood repair in a pinch.
