Joel OF Posted November 8, 2017 Share Posted November 8, 2017 Does anyone know if T wash gives the same visual results on zinc sprayed surfaces as it does on galv surfaces? So far I haven't applied T wash myself and have only had the galv firm do it. Close up snap attached of a plant support with galv + T wash combo. It's a popular look with customers on garden products and I have something that I want that finish on, but don't trust the heavy handed galvers with.

Marc1 Posted November 8, 2017 Share Posted November 8, 2017 Only one way to find out. Don't see why it wouldn't unless the zinc is not recent or is contaminated. You can apply oil after the T wash for a very nice effect. Quote Link to comment Share on other sites More sharing options...

Does oil not just wear off leaving it to go back to the T wash look on it's own? Quote Link to comment Share on other sites More sharing options...
Gergely Posted November 8, 2017 Share Posted November 8, 2017 Hi Joel, I'm really not sure but I remember something Colleen Du Pon said/wrote about this - maybe it's worth a shot to ask her. Bests: Gergely Quote Link to comment Share on other sites More sharing options...
Marc1 Posted November 8, 2017 Share Posted November 8, 2017 Nothing is forever in something that is exposed to he weather. Twash is a mordent to facilitate painting galvanised steel, not to leave it as is. You can use Danish oil as your top coat, but the best is to experiment with what you have in your particular environment. Quote Link to comment Share on other sites More sharing options...
