Zinsser Proffesional Mould, Fungi and Algae Killer and Remover 500ml

There’s nothing I didn’t like about the product, I bought this along with the degreaser - it’s the best thing I’ve ever used! First I used the degreaser (red bottle) and wiped away any black mould and some stains on my bedroom wall with ease. After leaving it to dry, I sprayed with the mould killer in areas that needed it. Again, leaving the wall to try before the last step. For the last step, I painted the wall with a white paint recommended by a B&Q employee who knew about the spray products and my intention to paint over it. The paint provided (i think) adds a sealant and colour white to stop the wall in the affected area to get damp. It’s been a few months since I did the job, still looking great and no sign of black mould returning - couldn't be happier and highly recommend this spray with their degreaser too!

Seems ok so far but only time will tell but make sure have a window open when you use it

Got rid of mould, making the area look 100% better

Not cheap but does what it claims

I didn't find it to be greatly effective on wallpaper, bleached diluted with water seemed just as effective if not a little better.

A Good Stong application was needed, seems it has done what it says it would do, But only time will tell

This product is excellent would recommend.

Compared to other Zinsser products like their paints which are awesome, this has been a complete let down. We tried it on the silicone in the bathroom, walls, ceiling, skirting... Mould stayed there as if nothing had been sprayed on. I went back to the good old Astonish mould cleaner and job done. I wanted to try something different due to the bleachy smell of Astonish. This one has no smell. But as it turns you can't beat good old bleach so we'll be putting up with the smell for now.
