Anything to treat a mouldy shed.

How to treat a shed? buy it a new porch?

Sounds like it's not drying out. Is the mould inside or out? If inside, I'd try to improve ventilation first.

To get rid of the mould, I'd wait for a dry spell and let the shed fully dry out (inside and out) and then get a mould remover and spray it all over (making sure you get it right into the crevices). When that has dried, then repaint to taste.

Give the affected areas a good brush down with a wire brush. Then if you can get hold of some good old fashioned creosote coat it with that. Otherwise give it a good dowsing with a solution of J*E*YE*S fluid and water and then coat with a good quality preservative when dry.

the green stuff is like areas that have been in shaded damp

You used to be able to buy copper sulphate powder from Boots and then add water to paint it on as a liquid - I daresay it's been taken off the market now though.

It's not generally available to Joe Public, but good old fashioned creosote will stop just about anything in it's tracks for years. BUT don't get it in the ground where you intend to grow fruit &veg.
All those modern pretty coloured fence and shed coatings are just that, pretty and have little real protection for the wood as you have proven while coating twice a year.

Something oil based is whats needed. Indeed if you can stand the smell get some used engine oil and dilute with a drop of diesel. Apply this to all the timbers. It will smell for weeks, but thats the end of regular painting for 5 years. DO NOT get this or creosote on your skin!
Downside is you will struggle with a nice water based colour anytime soon afterwards, so pretty and ricketty shed or secure black eyesore!

I tried to get some creosote but apparently the euro imbeciles have banned it for general use.
Will try some *****
Thanks Jimmy

It's so silly Jimmy. You can type in Flash, Harpic and Domestos but not J*E*Y*E*S

Jimmy try creoseal which was brought onto the market to replace creosote not as good as the real thing but still effective, and hunt for a suppler where you will be able to buy a greater quantity a lot cheaper, in the GCs its about �9. for 4 lts. I can get it from a local supplier, 25lts for �40. but no doubt you may be able to get even cheaper

I used to work with companies that made/sold "wood preservatives" but in truth these are only barriers. Must do not inhibit fungal growth or insect damage. Creosote was the best all rounder but as we know it was banned because of benzo-a-pyrene.

Creocote as a replacement is just as effective for fungal growth but no so for insect damage. Most people dont pay enough attention to end grain, this acts like a wick.

If you're painting over the green 'mould' it will just keep growing back through...

You need to brush it off, maybe wipe it down with something to kill it off and then paint over it. Also, increasing ventilation and decreasing moisture (dripping gutters, etc) should help as well.

I wonder why that happens,it�s like they don�t want it mentioned here. I�ve never bought that but I get a bit of green algae like that on my shaded driveway,if you can�t brush it off with washing up liquid try sanding it. Use a good water repellent shed paint that would protect against algae growing. I don�t think preservative is water repellent.

The J fluid thing is historical. Admin blocked it after complaints from somewhere official if I recall. So long ago I can't remember exactly. It's just stayed blocked for some reason, as are some swear words.
*** and that's NOT an invitation to the start trying to work out which ones!!!!!
