How Many Coats of Paint are advisable for painting?
DIY painting is not just a job for those with brawns. One needs mathematical intellect to estimate as accurately as possible the amount of paint needed. Buying too little paint is troublesome because one has to make another trip down to the paint shop and leaving half-finished coats of paint to dry unevenly can result in a bad paint job. If one buys too much paint, the excess paint will go to waste especially if not properly kept as it will tend to harden over time. The simple mathematical formula for estimating the volume of paint needed is square feet of the area to be painted multiplied by the number of coats needed. While square feet can be easily measured, determining the number of coats necessary can be a tricky affair.
If you are recoating your wall with the same colour, one coat is sufficient but two coats of paint will ensure better colour retention. If the previous condition of the old coat is paint is looking tattered and cracked, we would recommend two coats of paint.
If you are changing the colour of your wall, two scenarios are possible. First being that the current coat is lighter and you want to paint on a deeper, darker colour. In this case, one coat of paint should effectively cover the previous colour. However, as aforementioned, one might want to do two coats to ensure a better finished look.
If the current coat of paint is darker and one wants to do a complete makeover with a lighter colour, using tinted primer can help to save time and money. The shade of the tinted primer should be about half of the final colour one desires the wall to be. However, the most suitable foundation colour that one should use as a base can be very different from the actual colour you want your wall to be. For example, bright blue primer is the best base to use if you want to paint your wall dark red. Thus it will be best to consult a professional painter or someone at your local paint shop to determine a suitable primer colour.
Besides considering colours and the condition of your previous paint job, the quality of the paint you are going to use plays a big part in helping to estimate how many coats of paint is needed. The higher the grade of the paint, the better its pigmentation, therefore one would need less amounts of paint. Unfortunately, the trade-off is that better quality paint is also more expensive. One should also consider factory-mixed paint colours instead of trying to self-mix paints to get the desired colour. Self-mixed paints often do not cover the previous shade of colour very well and one might end up using more coats of paint. 
The bottom-line is search and find a trustable professional painting company to avoid a bad paint job outcome, and determine the number of coats necessary!
