How to Calculate Your Eterna-Kote Silicone Requirements
Please note : an average campervan roof requires 2 x 3.4L containers
Number of Squares Metres to Cover ÷ 1.76 = Litres of Eterna-Kote Silicone Required
Therefore, divide the square metres by 1.76 to calculate how much you need?
e.g. 36m² divided by 1.76 is 20.5 litres
N.B. Coverage depends to some extent on substrate – for example, asphalt roofs with chip may require more product whereas a metal roof may require less
To Calculate Square Metres
Multiply the length of the area x the width of the area to calculate how many square metres you are covering e.g. 3m long x 4m wide = 12 m²
For non-rectangular areas you need to break down into smaller rectangles. For instance, an L-shaped surface can be broken into 2 smaller rectangles (see illustration below). Add the 2 areas (12 + 24 = 36m²)
3m x 4m = 12m²
3m x 6m = 24m²
Total Area = 36m²
For areas where you will not apply product (e.g. skylights), subtract that area from the total.
