Painting of the house is seen by some as a very easy job to do, but if you must do it well I have to tell you that you need a professional painter to do the job
There are professional decisions to be taken before painting a house.
What of the risk of climbing a very high ladder and working for hours that you were supposed to use for your business. Paying a little extra to a tradesman will not diminish but increase you. Painting involves you moving heavy equipments and furniture around do you have height phobia?
Colour evokes emotion; infact a colour can give you an excellent idea of what a building is used for without you having any other clues.
Colours are used for branding you can see this prominent in our banks-bankphb, has blue and yellow, trace of red in UBA and intercontinental new buildings will reflect a lot of blue and yellow. The fast food restaurant for instance has a particular colour common to them all a grade or shade of wine and red.
Inspiration from environment-When you want to decide on a colour to use ,get inspiration from your immediate environment presently you are staying somewhere, you can check the furniture to start and look for colours that are of darker or lighter shades to blend with it. Your rug or window blinds can give you a good idea of the colour you may use. Most houses uses at least 3 different shades of colour, one the lighter and the major one for the walls the door and other attachments like window hood, heaves etc are used to get the best visual.
The houses around you are a good source of inspiration especially when it is a residential neighbourhood, for commercial you may decide to have a contrasting colour to easily differentiate your building from others for identity, the colour of your can also determine the one you will use for your exterior and the colour of your furniture will have to harmonize with the exterior.
Light colour will make your house seems larger and dark siding or bands will make your house seems smaller.
Contrasting colours will draw attention to architectural details in a building but to much of it will cause disharmony to your eyes.
The more intense a colour is, the longer is going to take to fade dark colours absorbs more heat and suffers more moisture problems that is why the larger portion of the building must be light.
For the sheen, of your paint (or texture)- Semi-gloss, glossy or flat. The glossier the surface, the more likely is going to show imperfections of brush strokes and touch up marks on the other hands glossy surfaces are easier to clean. The common thing is to use flat paint for walls and semi-gloss for columns window hood etc and railings and window sashes will be better painted by gloss.
To get a good painter the best option is to visit local paint sellers in your area , if they have customer that has been buying for long, this is a sign that the guy has experience in the job and his services could be employed.
Also look at houses next door one will be painted better than the rest so you can as well ask your neighbour for the painter and if you seen the building you are going to make use of is painter check how the painter was able to protect areas that were not supposed to be painted like concrete pavement, roofs, plants.
For the interior how was he able to protect the furniture the time he spent in completing the job is also important to you.
You can also ask from friends around and when you are ready to finally give in him the job ask for a comprehensive proposal the quotations that will include colour type,volume and mixture.
Use colour scheme when you are deciding on which colour to use, you can choose one colour and add varying tones of it by lightening it or deepening it. A complementary colour is to mix colours that lie opposite each other in colour wheel like blue and orange ,red and green ,yellow and purple. These colours are contrasting colours and when they put place together will create exciting effects.
And a related scheme is using colours that lies side by side in the colour wheel e.g green & blue or with red, orange & yellow which creates harmonious effects.
To choose colour most people will start with magazines,books.
There are no straight rules for choosing colour, the basic principle are hue,value intensity and temperature. Hue simply means colour which is the combinations of primary colours with different values and intensities.
Value is lightness of a colour which is determined by the amount of white mixed with it. When a colour strikes you as light, medium or dark then you are talking about value.
Intensity is the measurement of the brightness of a colour, that is when a colour will strike you as bright or dull then you are talking of the intensity. Low intensity colours are used as the main colour.
Colours are reffered to as warm or cool,red orange and yelloware warm colours,while blue green and likes are cool colours.
When painting the exterior, consider also the landscaping to be able to create harmony with your environment. Not all colourswill retain there looks due to the effects of sunrays and rain and some may have to take more coats to get the desired effects. The best ones are neutral toned with a medium value. That is why you see most often light or medium brown and beige colours are the ones used. The worst colours to use are pure colours like red and yellow which will oxidized very fast.
As I said the interior will have to be determined by the furniture you are using depending on what you want, it could be dramatic cool or simply a non noticeable interior with very plain colours.
