Another problem with the same rental ( see clothesline thread) It's a 1970's lockwood and the cladding has an ingrained black and/or red mould! in it, especially on the south side. We've tried light waterblasting, and washing down with a brush, now want to try to spray on 30 secs or similar product, have you had any success with these products, TIA

Worth a try but make sure you get the mix diluted exactly right, or more dilution than recommended, so the chlorine content doesn't bleach the paint.- read the instructions carefully.

no chlorine in 30 sec but yes do a small area out of direct view as a test patch with whatever you use
chlorine will do the job, much cheaper too, but dilution has to be right, 5 ltres at 42% for $9 at mega, needs to be mixed at like 1 to 30 ( real soft ) or it will bleach, and kill everything including your clothes, spray it on and leave it for a week, spray again then ignore it, it will take about 6 weeks to actually show effects

#3- 30 Sec has sodium hypochlorite bleach in it, and warns of bleaching on gloss paints, fabrics,.if mix not correct.

I think there is a 30sec bleach formulation and a 30sec spray and walk away type non bleach formulation

i think you are better to enquire from the lockwood ppl in rotorua.not a newbie. more an older person because he would have a better knowledge of it.

Once the mould has appeared, its very hard to remove unless you try some strong bleach from a cleaning supply shop[usually 5%] as opposed to 3% from supermarkets. I sell a moss n mould product @ cantabchemicals.co.nz but it wont help you in this instance; only a lot of scrubbing. Good Luck!

Bugger. Ok thanks for that, I was hoping to clean it and then paint it sometime soon, sounds like to much hard work. Wonder if i can get away with not doing it for another year, lazy huh, Thanks

use OUTDOOR CLEANER. give it a good spray, leave it a while, then waterblast it again. even if stains are ingrained the mould SHOULD be dead and you can paint over it.I did this to back of my house, it had green goo and mould. it never came back.

Thanks Shadow, when you say leave it awhile, are we talking few hours few weeks. I'm hoping a few weeks as i want to be able to spray it, leave it for a month till this weather is better to paint in, to hot at moment, then do all the prep work which is considerable for a Lockwood, then paint. Hoping to do the roof soon as that badly needs doing, and would benice to get the house painted this Autumn, will look the flashest house on the street - from the outside at least,needs new curtains and new carpets, new lino,etc etc, but new tenants first, some that actually give a toss about how clean the house is, anyway, thanks for your advice, off up there this morning and will go see the folks at the paint shop for there advice as well.
