Excellent value, great performance- a really good anti mould solution
I got sick of the mould growing in the top corners or walls and ceilings in rooms with exterior walls. We ventilate the house, run and dehumidifier and still some rooms it comes through. The bleach based spray treatments are aren’t ideal and anti mould paint is expensive. Is this solution? Yes it is. You’re not restricted to the colour of anti mould paint because you add this to the paint of your choice - meaning you can make your favourite colour an anti mould solution. Since we’ve used this, the areas painted have remained mould free. This is a good quality solution that’s easy to use. It’s so much better value for money than premixed paints too!

This anti-mould additive works really well (for me, that is)
This additive is excellent. I just mix the required amount (as stated on the bottle) into a new tin of emulsion, stir it in (really stir it well is my advice), then stir it regularly when painting. It works! I added it to a Crown emulsion and painted a North facing wall two years ago, with no mould returning. I did make sure I treated the mould on the wall first,( as that is essential because painting over it with normal paint won't get rid of it). Then two coats of the emulsion with the anti-mould additive and jobs a good un.

"Effective for Tackling Dampness – Time Will Tell!"
First Impressions: I bought the Dryzone Anti-Mould Additive (100ml) for my damp shed, and it seems like a solid product so far. The application process was simple, and the instructions were clear. I mixed it with the paint and applied it to the affected areas. The mould protection seems promising, but as with any anti-mould solution, time will tell how long-lasting it is. Design and Build Quality: The bottle is small but efficient, and the product mixes easily with paint. The anti-mould additive itself is a liquid, and it’s designed to work with regular paints to stop mould growth at the source. The formula seems strong enough to handle minor damp problems without being harsh. Ease of Use: The Dryzone Anti-Mould Additive was incredibly easy to use. I mixed it into my shed paint, and it went on smoothly. No mess, and no complicated steps. It’s great for anyone looking to add an extra layer of protection against damp and mould without a complicated application process. Performance: As of now, the additive seems to be working well, but I’m still waiting to see how effective it is long-term. The shed feels drier, and there’s no noticeable mould growth yet. I’ll be checking back in the coming months to see if it holds up through the winter months. Value for Money: For the price, this 100ml bottle goes a long way, especially if you’re mixing it into a larger volume of paint. It’s a good value considering it provides extra protection against mould without the need for special treatments or sprays. Pros: ✔ Easy to mix with regular paint ✔ Helps protect against damp and mould ✔ Simple application with no mess ✔ Affordable for the coverage it provides ✔ Can be used for multiple projects Cons: ✖ Time will tell if it’s truly effective long-term ✖ Might need to reapply if the damp problem is severe Final Thoughts: The Dryzone Anti-Mould Additive seems like a great solution for keeping your shed or home damp-free. It’s easy to use, affordable, and offers extra protection against mould. I’m hopeful it’ll continue to perform well, and I’ll be checking for results in the coming months! Rating: ⭐⭐⭐⭐☆ (4/5 stars) – Great for tackling dampness with time to prove its effectiveness!

Brilliant product.
Works. I bought this product for my mother's cellings as she had a bit of water stains and mould. She has humdinger. I cleared the area of the water stain and mould then once it dried I mixed half of the ani mould liquid into the white paint. then poured it into a painting tray and painted my mother's ceilings. It works and it has been around 2 to 3 months now and my mothers ceiling and walls look fantastic. Yes I put painted my mother's walls too. Basically we were told it is wear the roof is there is no air flow, so we were told by the housing, but no one will fix it or put a window in the roof. Even though my mother has not mould for many years, but in the concerns and a few other places. The housing was supposed to change the panels around the house every two years as it it made from wood and it gets wet and this creates more mould and water stains. Years ago the housing use yo built houses with wall vans in every room to let air go in and to your home, they do not do these now everything is electric air vent so we have to pay for it. This ani mould product is great to use fantastic value for money. I definitely buying again. Packaging was secure and fast delivery.

It works great so far
After 6 months, my ceiling above the shower is still white with no mould. It mixed well and painted as normal, the marks on the bottle were very handy to know how much to use for the paint can size. Great stuff!
