I had a leak in my kitchen which has a flat roof and some rain water came through the ceiling so I looked for something to repair it. This came up in a search and I decided to give it a go. It is an aerosol that you have to shake quite a bit to get it to work properly, this can be quite tiring and made my arm ache so I would recommend doing this in a seated position so as not to make you dizzy, there is more of this and I will come onto that later. You then have to get onto a chair and point it at the damp patch and hold the nozzle down so that the chemical sprays out onto the affected area. At first it looks like nothing is happening but it soon becomes clear that the spray is, in fact, depositing a fine residue on the flat surface so that the spores of the damp patch are covered up. It does not take long before the staining diminishes and your, in my case ceiling, is back to relative normality. Having descended from the chair I perused my handiwork from ground level and, if I squinted hard enough, it looked like there had never been a damp patch at all (which I know is factually incorrect of course). It may have been the squinting but I did notice that my head felt a bit fuzzy after using this product, it was of course, more likely to have been me breathing in some of the fumes which is not recommended. The sensible thing would be to wear a mask or at least tie a (clean) hanky over your mouth but I had not through of this and was too excited to spray over my damp patch. It is also not recommended that you spray this product where there is food nearby. I had left a couple of peaches on the kitchen worktop that tasted a bit strange afterwards, luckily I only took a small bit out of each, they were not particularly ripe anyway so I threw them into the composting box in my garden.

For professional decorators I am sure this is not a problem. The spray can version is much quicker and easier to apply the thickness you need. If you need a very thin coat (if you are applying layers) you can see an even finish without going back over to assure yourself you have a proper layer. Worth the extra money. ## Frequently Bought Together - Polycell Damp Seal Aerosol 500ml , White , Pack of 1 - HG Mould Spray, Effective Mould Spray & Mildew Cleaner, Removes Mouldy Stains From Walls, Tiles, Silicone Seals & More - 500ml , Pack of 1 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/48912703-polycell-damp-seal-aerosol-500ml-white-pack-of-1](https://www.desertcart.co.th/products/48912703-polycell-damp-seal-aerosol-500ml-white-pack-of-1) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-11*
