Hi Roger,?
?
That's interesting to hear you experienced issues with mold, I'm curious to hear if you were using Allback linseed oil paint??
?
Linseed oil paints do require a minimum percentage of zinc-oxide to inhibit mold growth (previously White Lead was used). When Allback was introduced to the US market ~2007, they offered zinc-oxide as an additive, but did not include it in the base formula of their paints, so many users experienced mold issues.?
?
It is my understanding that Heron, Brouns, and most of the other linseed oil paint producers include the minimum percentage of zinc-oxide in their formulations, but it's worthwhile to confirm as an informed consumer.?
