This is a rough guide only. The amount of paint required is based on average conditions and application methods. Please check the individual product spreading rates and application guides if you require more precise information. You may need to change the Product type for each area you wish to paint i.e. the amount of paint required for a given area is not a combined total of primer and antifouling but the amount required of each product. The protection factor for all primers and antifouling is two coats for 'good' and three coats for 'best'. The amount of paint applied with each coat varies considerably on the method of application so this is just a rough guide.
