# How to calculate the required materials for white washing a building wall

Construction Software

In this construction video tutorial, you will learn the process for working out the quantities for white wash.

The materials required for white wash may contain lime, glue and color (optional). So, calculation is done for finding out quantities of lime, glue and color.

The following points should be taken into consideration before starting the calculation process :-

1) 2 kg per 10m2 (surface area) of white fat lime is necessary for a single coat white washing containing 0.06 kg glue.

2) 2.8 kg per 10m2 (surface area) of white fat lime is necessary for double coat white washing with 0.06 kg glue.

3) 3.5 kg per 10m2 (surface area) of white fat line is necessary for a triple coat white washing 0.12 kg glue.

4) The quantity of color may be lump sum. As there does not exist any particular way, it is based on past experience and choice.

In the video, the solution is given to the following example :-

Work out the quantities of lime and glue of three coat for a plastered wall with length 15 m and height 5 m.

To determine the entire area for white washing, multiply both length and height of the wall as follow :-

15 m x 5 m = 75 m2

The quantity of white unslacked lime = 3.5 kg/10m2 x 75 m2 (based on point no. 3) = 26.25 kg

The quantity of glue = 0.12 kg/ 10m2 x 75 m2 (based on point no. 3) = 0.9 kg or 1 kg (approx)

To get more clear ideas, go through the following video tutorial.
