    Default Render discolouration

    I just finished rendering an outdoor feature. I subsequently coated the whole thing with this product: https://store.rendersupplyco.com.au/...ler-15-lt.html
    Its a tinted elastomeric render sealer. After two days, it rained quite significantly, The coating itself was dry by this point. I can see that wherever the rain was flowing the most, it got lighter. To be honest, I've never used the sealer stuff before but was quite pleased with the colour match before it rained. I think the darker bit is pretty much the same as the original colour.
    Here is a pic of part of it:

    I've tried scrubbing it and powerwashing it (from a safe distance) to see if the normal colour will return but nope.
    Can anyone figure out whats going on. Not sure if I'll need a recoat and if so, whats going to prevent it from happening again?

    Whilst it may have looked dry, the rain has obviously caused damage.
    Coat it again or at the very least talk to the suppliers of the coating.

    Well I coated it again. This time, it went for 4 days without any rain before it rained today. It seems to have done the same thing. Discoloration like above. Interestingly, when I put water on it myself nothing happens. Something about the rain is causing it. I can't fathom why this is.

    I'll have to contact the store that sold it when I get a chance. The brand ICONIC is kind-of sketchy their site is extremely rudimentary and their email doesn't work anymore.

    Yes, re Iconic, I couldn't find much at all related to coatings except for the link you posted

    The manufacturers website is just as helpful.
