ZinsserProffesional 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

This product is excellent would recommend.

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

Well packaged, wonderful product.

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

I used this to help combat black mould in my damp house

Not cheap but does what it claims
