Was good but a the smell lasts a long time ,need a mask but does the job

As someone living in the UK, I recently tried out the Polar Damp & Stain Block Spray - Matt White, and it has been an absolute lifesaver for my home. I used it to tackle dampness and stains in various areas, and it truly delivered outstanding results. The thing I really liked about this spray is its ease of use. It comes in a convenient 500ml bottle, which was perfect for my needs. The spray nozzle provided a smooth and even application, making it effortless to cover the affected areas. Plus, the matt white finish seamlessly blended with the surrounding surfaces, giving them a refreshed look. However, there was one thing I wasn't particularly fond of. While the spray effectively blocked dampness and stains, it did have a slightly strong smell. Although it dissipated after a while, it would have been nicer if the scent was milder. Overall, I highly recommend the Polar Damp & Stain Block Spray for anyone dealing with dampness and stains in their homes. It's a fantastic solution that gets the job done efficiently. The convenience of the spray bottle and the seamless finish it provides make it worth the purchase. Just be prepared for a temporary strong smell during application.

Used the Polar Damp & Stain Block Spray to cover a few small marks (damp and general mystery stains), and it’s worked well so far. It’s very easy to apply — quick spray, decent coverage, and no complicated prep beyond the obvious cleaning. It’s ideal for smaller spot areas rather than whole walls, and it blends in nicely once dry. It covers effectively without needing loads of layers, and doesn’t feel like you’re emptying the can just to deal with one patch. If you’ve got small stains from damp, mould, nicotine or similar and want a quick fix without breaking out full paint tins and rollers, this does the job. Five stars. Handy little problem-solver for targeted areas.

Paint is ok.But smell is horrible.If you don’t have windows to open then don’t buy this.For outdoor it’s ok.Otherwise smell is horrible for breathing.

Really good item I use this brand for other jobs I do and always good results

Edit: Seller has provided a full refund for my order without any prompts as the product did not work. Great customer service. I've bought this product multiple times before and absolutely loved it. It sprays easily, and covered the walls, and seamless blended in with the paint. You couldn't spot where I used it. Smells a little, but open windows and it goes away quickly. But in my recent purchase of 2 bottles, I noticed the packaging has changed. The spray now leaves a dark mark on the walls and the area I spray on does not blend with my paint. It looks awful, and now I've to buy more paint to cover the patches. I dont know if I got a bad batch or if there's a change in formula, but it does not work anymore. Very disappointed!!

It does cover stains & it is easy to use, but it smells HORRENDOUS and is super ‘toxic’ in the air! I thought it would smell, but it is not viable to use this then remain in the space and is much worse than the paint on stuff I’ve used before.

This spray works really well and did exactly what it’s supposed to do. It covered the mould and stains effectively, and the results were visible quite quickly. It’s easy to apply and does a good job overall. The only downside is the strong smell, so I had to ventilate the room well after using it. Aside from that, it’s a great product and I would recommend it.
