Final tips for perfect painting

Eighth tip: brush type
It is important to choose tools suitable for the task: from proper wash brush and detergent to the correct brushes and rollers for applying, especially, primer and topcoat.

Waterborne products need a softer brush than the oil-based. Waterborne paints should be applied with a slightly softer brush, while oil paints require a little stiffer bristles. If the bristles are too stiff for the paint, it can cut through and leave unsightly scratches, but if the paint is too tough and the bristles are too soft then this combo will form clumps and the paint will not be layered evenly.

Ninth tip: correct thickness/number of coats
You should follow the manufacturer's manual for the application. It says how many square meters each liter of paint should cover and how many coats need to be applied. Generally, it is always recommended at least three coats. Simply saying, if you have bought the right amount of paint according to the walls area of your house and you are left with many liters of paint, then you have painted too thin.
When the outside paint has busted shortly after you have repainted - the reason behind is almost always too thin paint layer. Paint manufacturers guarantee durability of their products only if the application is done right. Especially outside the paint coat thickness has the crucial importance for the conservation of the substrate for paint durability and overall good and nice result.
