THUMB RULE TO CALCULATE QUANTITY OF SHUTTERING OIL

Shuttering Oil or form-work oil is high-quality mineral oil that is applied to the inner surface of form-work before concreting .Shuttering oil work as a releasing agent between shuttering and the concrete.

Why we use Shuttering Oil ?

• Shuttering oil prevents water absorption from concrete by the wooden form-work.
• Shuttering oil prevents sticking of form-work to the concrete surface thereby permitting easy stripping of form-work after the concrete has hardened.
• Shuttering oil prevents steel form-work from corrosion.
• Shuttering oil helps provide good finishing surface of the concrete with minimum defects.
• Shuttering oil protects the form-work and hence the form-work can be reused several times.

For Example :

we have Slab area of 1000 square meter , Then how much of shuttering oil needed are describe as following :-

Note :-

1 Liter shuttering oil cover up to 35 to 45 meter square area in wood shuttering.

1 Liter shuttering oil can cover up to 65 to 75 meter square area in pigment-free steel plates.

Now :-

WOOD SHUTTERING:

Shuttering oil = Total area / 1 litter oil covering area.

= 1000 / 35.

=   258.5 liters

STEEL SHUTTERING :

Shuttering oil = Total area / 1 litter covering area.

= 1000 / 65

=  15.38 Liters
