Review: Successful Application - 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. 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. ## Features - Causes serious eye irritation. - Extremely flammable aerosol. - May cause drowsiness or dizziness. - Pressurised container: May burst if heated. - Repeated exposure may cause skin dryness or cracking. - Instantly Blocks Damp & Stain: With its dual-action formula, this quick-dry anti mould spray acts as both primer and sealer, combating dampness, mould, and stains on walls and revitalising your living space with no harsh odours - Long-Term Protection: The damp seal paint addresses tough stains like grease and smoke.

Obviously it pays to keep about 30cm or 12" inches away from the target 🎯 area when spraying ' and try to keep a steady sweeping motion going as you spray the area '. You should make sure the surface is clean and dry before you start ' cos you want to create a surface that the paint will stick too ' but i found it went on beautifully '. I even had enough left over to help my neighbours son's room too '. Obviously you should clean any window 🪟 vent's and open them to create circulation to stop mould or damp in the first place ' and it's often helpful to open a window for half an hour a day to prevent any potential build up of mould etc in the first place '. I recommend keeping furniture a few inches away from walls to aid circulation ' and frequent use of a kitchen or bathroom extractor fan can make a massive difference '. You should always follow the manufacturer's instructions ' and i believe this was an excellent product ☺️ i didn't notice any smell either 😃 ## Frequently Bought Together - Polar Damp & Stain Block Spray - Matt White - 500 ml - Anti Mould - Stops & Removes Mould & Stains - Stain Blocker paintFor Interior Walls & Ceilings - Wood, Plaster, Cement - HG Mould Spray, Effective Mould Spray & Mildew Cleaner, Removes Mouldy Stains From Walls, Tiles, Silicone Seals & More - 500ml , Pack of 1 - Polar Anti Mould Paint - Brilliant White Matt Finish - 500ml - Prevent & Control Mould On Internal Walls & Ceilings - Easy To Apply --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/329605245-polar-damp-and-stain-block-spray-500ml-matt-white-low](https://www.desertcart.sn/products/329605245-polar-damp-and-stain-block-spray-500ml-matt-white-low) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-01*
