Duroplastic misleads their customers on catalyst use.

I bought 20L of Pool Blue Topcoat from Duro on 3 Nov 2023. The catalyst measurement they they recomend with their product is 100ml per 5L of paint, except on a hot day when it should be 75ml for 5L. It was a hot day so I decided to add only 45ml of catalyst to 5L. The paint turned to jelly in just 5 minutes and was solidly hard in 8 minutes. I think they purposefully do this for you to waste your product to come and buy more.

You can use 15ml of catalyst with 5L of paint and it takes 20min to dry. Don't use their misleading instructions.
