Calculating The Amount of Paint to Use On Walls
In the absence of paint, prepare the new color will not be identical to the previous, making it impossible to review the details that we have been. If we prepared the same color, but with different brand will surely be a change of tone. If the paint on, we lose money, and though we keep, we do not often use. The water-based paint is usually decay over time. and oil as synthetic enamels and varnishes dry.
As the calculations
To begin, measure the surface to be painted by multiplying the height by the width or base to obtain the square footage of each wall or flat paint. This rectangular surfaces, for example:
2.5m high x 4m = 10m2 surface base
Triangular wall or roof slope with a strong measure to half its height and multiply by the meter base. For example: 4-meter wall base with a side of 2 meters and a 4-meter
Basic 4m x 3m = 12m2 surface height
After the calculation of the areas we need to know when it yields the paint we use. In all packaging indicates an estimated yield per liter by hand. Keep in mind that a quality paint more than an economic yield. Moreover, the surface is very much in the paint rough walls can pay half or less than indicated on the package. Remember that the application of fixative sealant or similar material increases performance.
Usually the pay wall paintings:
- 10 m2 per liter with quality paints
- 6 to 4 m2 per liter in rough and textured finishes
- 5 m2 per liter economic paintings
- 12 m2 per liter of synthetic enamels
Once the paint surface calculated by adding all partial areas of all walls, divided by the redeeming of painting, and multiply it by the number of hands. For example:
(Wall 40m2 / 10m2 of output per liter) x the number of hands needed
(40 / 10) x 2 = 8 gallons of paint
Discount is not recommended because doors and windows should always be some paint left over, if performance turns out to be smaller than the package indicates, besides the greater absorption of the wall during the first hand with respect to the following.
