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.
Paints in powdered form require the addition of a liquid to prepare them for use. The manufacturer's directions as to the amount of oil, varnish, water, or other vehicle required should be followed.
Reading also needs good visual perceptual skills. Shape perception allows us to recognise the similarities and differences in the shape of letters. Figure-ground perception is needed to be able to see the separate words on the page and the separate letters in the words. Spatial perception allows us to see where one word starts and another ends and which way round a letter must face.
How Much Paint You Really Need. How much paint you will need to satisfactorily complete a paint project is determined by 2 factors. The first, paint coverage, is a familiar concept to most people. It simply concerns the square footage of surface area to be painted, and "paint coverage calculators" abound on the web. However, the second concept, paint color coverage, has a much more pronounced effect on how much paint will be needed and the cost of paint projects. Unfortunately, paint color coverage is a novel concept to many painters and, in fact, is poorly understood even by many professionals. Knowing the secrets of paint color coverage will allow you to reduce the number coats you have to apply and minimize how much paint you have to buy.
Technical advancements are constantly being made to improve the life span, durability, wear and performance of exterior paints. The Akrylatfarg range at Ray Munn, for example, is an environmentally sound water-based option.
Special paints have been innovated from different consumer insights and brilliant paint technology that allows specific paints for specific needs.
Mixing. Paste paints, such as aluminum, resin-emulsion, and lead-in-oil, should be stirred with a stiff paddle and reduced to painting consistency with the liquids recommended on the manufacturer's labels.
