Paint, unremarkable though it seems, nobody would want to be without it. Paint is used on exteriors and interiors of homes and other buildings, requiring little more than a roller and a brush to apply. However, without it, walls would seem bare and there wouldn’t be nearly a many colours available for the environments in which we live our lives. Paint can be applied directly to many surfaces and it is possible to apply it to an even wider range of surfaces if an undercoat is first added. An undercoat is also made of paint but it is a form of paint which adheres better than regular paint and will allow the regular paint to adhere to it, when that is applied. Undercoat usually only comes in white or a pale colour, whereas pain is available in every colour of the rainbow - and more. Anybody who has ever tried to choose paint will know how tricky it is to get the colour right unless you take samples home. The first step is to get purchase paint sampler cards and make sure they are of the brand and type of paint. Learn the difference betweenexterior or interior, or 'wet' room vs dry room purposes. Imagine which colours would fit in which room and don’t be afraid to mix and match colours. Many people enjoy different coloured rooms or two-tone rooms in which one or more feature walls are utilised. Then, once you have decided on the colours you want, purchase a sample paint tin, which come in small sizes and are inexpensive, allowing you to try on the colour in a non-obvious spot first before committing. Finally, keep in mind if your family has allergies or sensitivities. Eco-friendly paints can now be obtained which are naturally low in allergens and chemicals. These now come in beautiful ranges of colours and are equal in quality to regular paints for both inside and outside.
