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.
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 good interior paint job is often 50% preparation and 50% painting. Do not rush in preparing the surfaces in your eagerness to get at the brush or roller. If you do not prepare the surfaces properly, you'll be back with the paint brush or roller in a few months.
Red is the color of fire, it instills joy, strength and confidence in people. In some languages red is a synonym of beauty and wealth. But we shouldn't forget that it is also the most aggressive color - if there is too much of this color, it irritates and wears you out. On the other hand small accents of red in the interior cheer you up and put you into a good mood. If red is the predominant color in your interior, it sets you into active and determined mode.
Today, it is increasingly easy to source ecologically sound paints, as most specialist ranges, such as Ecos, Earthborn, Georgina Barrow and Auro are available via mail order. There is a wealth of colour options in these pre-mixed ranges that include lush shades and muted palettes, reflecting their natural ingredients. Ecos continues to lead the field. It has recently developed Atmosphere Purifying Paint, which absorbs and neutralises volatile chemicals, solvents and VOCs from the atmosphere in a home.
Concrete Floors. Two general types of paints for concrete floors are varnish and rubber-base paint. Each has its limitations and the finish cannot be patched without the patched area showing through. Floor and deck enamel of the varnish type gives good service on concrete floors above grade where there is no moisture present.
A large whitewash brush is best for applying the wash. One should not attempt to brush out the coating, as in applying oil paint, but simply spread the whitewash on as evenly and quickly as possible.
