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.
Special Surfaces. WHITEWASH. Whitewashes and lime paints must be thin when applied. In fact, best results will be obtained if the application is so thin that the surface to which it is applied may easily be seen through the film while it is wet. The coating will dry opaque, but two thin Coats will give better results than one thick coat.
If you are grappling with the problem of choosing a woodwork colour to go with neutral walls, check out Architectural Colours by David Oliver, the founder of Paint & Paper Library. He arranged his off-whites for ceilings, cornices, walls and woodwork in chromatical groups and the concept has been so well received that chromatically arranged colours, such as soft greys, greens and pinks, have been introduced.
Playing fun games where word sounds are changed, learning silly rhymes and making up nonsense words helps children develop their phonics skills and auditory processing. If these are simply taught in a formal way, the child feels no real ownership and finds it harder to remember all the different sounds the written letters represent. If he plays games and experiments with the sounds in words, his feeling of being in control of the words and the sounds is greater, making it easier for him to learn and remember his phonics. He develops an actual concept of how sounds make up words.
Better still, you don't have to spend hours getting ready and hours cleaning up afterward. Premixed paints, electric-drill attachments and self-dispensing calking guns make short work of preparation. Cleaning up is a soap-and-water job for the rubber paints, or a quick dip in special cleaners for the oils. Disposable dropcloths and paper paint pails are used once and thrown away.
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.
To balance, you must grasp the interconnectedness of color schemes. All these interactions are defined in the color wheel, and it has been used to build color schemes for centuries.
