Review: Great but NOT a LOW odour !!!!!! - Giving 5 stars as appears to work very well indeed! But you cannot have the phrase ‘Low Odour’ as a USP when I can smell this throughout the house now and it almost takes your breath away! Only sprayed in two corners, door closed, windows in that room open widely… it’s still choking our air downstairs, So maybe just take that misleading phrase out?!
Review: A Lifesaver for My Home! - 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.

### ⭐⭐⭐⭐⭐ Successful Application
*by J***J on 7 March 2025*

Pleased with this product, used it a number of years ago with success and required it again. I had a very small localised damp spot in the corner of my room from an apparent unknown source. I purchased the “spray paint” type of applicator as opposed to the paint out of ease. Albeit, the smell from this is very very strong, no children or pets should be close, keep the windows open and plan the leave the room instantly, it’s incredibly strong. In addition, dependent upon your type of patch, the paint may be more ideal, as naturally the spray travels, arguably in my case the paint may have been more ideal as I had to mask off the area to prevent over application on other areas. However, all that technical aside, it works, I’ve attached a before and after. It goes on thick white, and is easily painted over. I also sprayed over filler I had put on in the area and it went over that fine and caused no issues. I managed to paint over again in two coats of Dulux Polished Pebble which is naturally light and still not shown through. Been on for about a year now, and no penetration, albeit there has been plaster cracking but that’s no discredit to the product as it’s a result of the damp area, I plan on to re fill the area again and should be fine after that. Would and will use again.
