You want to clean and impregnate your boat cover. You now know which products to use. But how much do you need?

No boat cover is the same

How much impregnating agent and cleaning agent you need depends on:

  • the type of boat cover
  • the type of boat fabric
  • the quality of the fabric
  • The extent of the dirt.

TIP: The following applies in particular to the impregnating agent: it is better to apply too much impregnating agent than too little. 

Some factors that influence the quantity you need:

  • A boat cover that is a few years old absorbs more impregnating agent than a new boat cover.
  • The inside absorbs less impregnating agent than the outside.
  • Fresh grime is easier to remove than grime that is a few years old
  • If your boat is close to industry or Schiphol, grime is more difficult to remove.
