After light sanding (beige) I applied over the existing rail an outdoor metal epoxy enamel paint to a verandah rails
( I combined 2 different brands Black with some white to get a grey all epoxy enamel)
An hour later it started raining for a number of hours
next day the paint appears to have leached exposing / washing
off the paint.
Q: is it the rain or the mixing of paints ?
Thank you so much for sharing your question about outdoor paint leaching onto your verandah rails.
I'm sorry to hear that the paint has not worked properly. Some brands are just not compatible and produce unpredictable results when mixed together. Then the rain came and did its damage to your paint job. I suspect that it was a combination of both factors that produced this current result. I suggest thoroughly sanding down your verandah rails and start from the beginning. This will guarantee that no other paint will interfere with the following paint job.
I recommend using White Knight Rust Guard Medium Grey Metal Primer Paint - 0.5L. This will provide a good base for the paint to adhere to. I suggest using White Knight Rust Guard Gloss White Epoxy Enamel Paint - 1L tinted to the colour that you like. Using a linked painting system will guarantee that it will produce a superior finish.
Any updates you can provide while painting your verandah rails would be much appreciated.
