# How to calculate surface area?

You need to find out how many sq M of paving needs to be coated, including any edges. For around the pool determine the pool length and width first in metres (one large step is a metre).

So (Length + Width) x 2 = perimeter, “A” in the formula below.

Now how wide is the pavement – path, which is “B” in formula below?

(Add any edges, like coping tiles if you want to coat these too for “B“).  So Sq M to coat is:  perimeter (A)  and width of pavement (B)  of your swimming pool.

Use following formula:

A x  B x 1.1

Example:

Your pool is 9m long and 4.5m wide that gives 27m perimeter.

Pavement width 1.2 m (inc coping)

27 x 1.2 x 1.1=35.7 sq.m (say 36 sq M)

In more complicated cases, (such as a free shape pavement), if you need help in measuring the surface area please send us the plan if available.
