Can I mix more Belzona solidifier (hardener) to make it cure quicker?
No, Belzona is an engineered polymer. Adding more or less of the solidifier will only decrease the properties of the cured Belzona Material, and may stop the material from even curing at all. The mixing ratio can be off by as much as 15%. A tip for mixing by parts (for a 3 to 1 mix ratio by volume) is to take 3 equal “blobs” of the base and 1 equal “blob” of the solidifier.
