For most applications we offer two types of Hempel coating systems to choose from - a Single Pack (Conventional) and a Two Pack (High Performance) system.
It is very important to choose the system which will best suit your requirements and a little time spent before starting could save you a costly mistake.
You should consider the following before making your choice:
Any existing coating
A two pack product should only overcoat another two pack system, whereas a single pack product can overcoat either a two pack or a single pack system.
If you decide to change from a single pack to a two pack system you should remove the single pack system first to avoid any risk of incompatibility.
Substrate construction & flexibility
In general two pack systems should only be used on structures where substrate movement is minimal. It is not advisable to put a two pack system on to carvel or clinker built wooden hulls as they require the benefits of the greater flexibility of a single pack system.
Experience of applicator
A two pack paint needs to be mixed thoroughly before use and can then be applied in exactly the same way as single pack paint, giving consideration to the more critical temperature and overcoating times.
Usage & Durability
What usage is the finished surface going to be put to? A two pack finish will withstand a good deal more wear and tear than a single pack.
Length of service
A two pack finish will last, on average, twice as long as a single pack finish.
