Questions & Answers

Is this a complete kit with hardener?

This listing is for the 2.5L Part A (Base) only. To complete the 1:1 mixture, you must also purchase either the Standard Curing Agent (YAA814) or the Fast Curing Agent (YAA815).

How do I know if it is compatible?

Check the SKU/MPN list. If you are fairing a yacht hull using the International Interfill system, this is the industry-standard fine finishing filler for that process.

Can this be applied above and below the waterline?

Yes, Interfill 833 is an epoxy-based compound that is fully compatible with submerged surfaces and topsides when correctly overcoated with a suitable epoxy primer or topcoat system.

Note: Professional use only. Please verify your system requirements against the references above before purchasing. Domain: 4boats.co.uk.
