What happens if you put too much hardener in paint?
too much hardener makes paint a bit brittle…..
however the bigger issue is adhesion.
in the old days you could mix paint to preference.
however modern paint formulas rely on “flash times” chemical reactions between layers..
How much hardener do I mix with paint?
Regardless of size, the chosen measurement must remain the same throughout the mixing process. A mixing ratio given as 4:2:1 normally means 4 parts of base product, 2 parts thinner/reducer, and 1 part hardener. However, some paint manufactures add hardener second, and thinner/reducer last.
What is the difference between reducer and activator?
Activators: activate the curing cycle. They come in different speeds: slow, medium, fast for use in different temperatures. Personally I use slow activator all the time. Reducers: reduce (old term was thin) the activated products.
What is reducer used for?
Thinners and reducers in automotive paints are both solvents used to thin paint. These additives make the paint flow better so the result is even, professional coats. While the purpose of the two is basically the same, thinners and reducers are used on very different paints. Using the wrong one could ruin your paint.
