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.
