You can even put it onto damp walls. It lets trapped moisture escape without causing anymore damage. When it's dry you can paint or wallpaper over it. BEFORE YOU START Make sure the cause of damp has been fixed. Open your doors and windows for ventilation and put down dustsheets to protect anything you don't want to get paint on. Preparation: Remove any wallpaper with a scraper and sand off any loose or flaking paint. Make sure the area you are painting is clean, if you've got mould, get rid of it with our 3in1 Mould Killer. You can paint onto damp surfaces, just make sure they're not dripping wet. USING YOUR DAMP SEAL Give the paint a really good stir, then use a roller or brush to put it on. If you're covering a small damp patch, make sure you are painting at least 30cm around the area. It'll be touch dry in 2 hours. After 4 hours it'll be ready to paint or wallpaper over. If the area is prone to mould, you can paint over it with our 6 Year Anti-Mould Paint. Usage Areas: All indoor walls and ceilings. Compatibility: Bare or previously painted walls and ceilings. Clean Up: Clean all brushes or rollers in warm, soapy water. Coverage: 5mΒ² Per Litre. Set Contains: 1 x Ronseal One Coat Damp Seal White 250ml Review: Delivery and packaging all good, no issues. I needed a small quantity of damp proofing paint for a small area on an outside wall in the kitchen. I found the size good for me as it was a a manageable size pot to manoeuvre and the paint itself very easy to use. Overall quality of the product was very good and im very pleased with how it turned out. I would recommend this product to others Review: Does what it says on the tin! ## Features - Ronseal RSLOCDSW250 One Coat Damp Seal comes in the following - You can even put it onto damp walls - It lets trapped moisture escape without causing anymore damage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008VQ6RDY | | ASIN | B008VQ6RDY | | Best Sellers Rank | #39,158 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #47 in Waterproofers | | Brand Name | RONSEAL | | Color | White | | Compatible Material | Plaster, Concrete, Brick, Gypsum Board | | Customer Reviews | 4.4 4.4 out of 5 stars (3,470) | | Customer reviews | 4.4 4.4 out of 5 stars (3,470) | | Date First Available | 13 May 2013 | | Global Trade Identification Number | 05010214851027, 07426984580902 | | Is Discontinued By Manufacturer | No | | Item Dimensions | 7.4 x 7.6 x 7.6 centimeters | | Item Form | Liquid | | Item Type Name | Ronseal OCDSW250 One Coat Damp Seal White 250ml | | Item Weight | 0.32 Kilograms | | Item model number | OCDSW250 | | Manufacturer | Ronseal | | Manufacturer | Ronseal | | Material Type | Silicone | | Model | OCDSW250 | | Number of Items | 6 | | Part Number | OCDSW250 | | Product Dimensions | 7.4 x 7.6 x 7.6 cm; 318 g | | Style Name | Compact | | Surface Recommendation | Wall, especially damp | | Unit Count | 250 Milliliters | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** RONSEAL - **Item dimensions L x W x H:** 7.4 x 7.6 x 7.6 centimeters - **Item weight:** 0.32 Kilograms - **Material:** Silicone - **Style:** Compact ## Images ![RONSEAL OCDSW250 250 ml One Coat Damp Seal - White - Image 1](https://m.media-amazon.com/images/I/61Huqqsdr1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***N on 10 April 2026* Delivery and packaging all good, no issues.
