This guide is for DIY enthusiasts and homeowners dealing with damp or stained surfaces before painting. The Ronseal One Coat Damp Seal Paint offers a quick and effective way to block stains and seal dampness in a single application, but it requires application to damp surfaces for optimal performance. It's a micro-porous paint that allows trapped moisture to escape, preventing future issues.

While it is designed for damp surfaces, if the wall is completely dry, lightly mist it with water before application for optimal performance and adhesion.
Drying time can vary depending on conditions, but it typically dries to the touch in 1-2 hours. It can be overpainted once fully dry, usually within 4-6 hours.
A 750ml tin covers approximately 6 square meters per litre, meaning one tin will cover around 4.5 square meters, assuming a single coat.
This product is specifically designed for interior use on damp or stained surfaces.
No, this paint seals dampness and stains; it is not a waterproofing product and will not stop active leaks.
Clean all tools and brushes immediately after use with warm water.
Yes, it is compatible with most emulsion and oil-based paints once the damp seal has dried thoroughly.
Ensure the paint was applied thickly and covered the entire stain. For heavily stained or porous areas, a second coat might be necessary after the first has dried.
The surface may have been too wet, too dry, or not properly cleaned of dust, grease, or mildew. Ensure the surface is appropriately prepared and has a light mist of dampness if needed.
This is normal for damp surfaces and the micro-porous nature of the paint. Ensure adequate ventilation to help the moisture dissipate.
Work in smaller sections and apply the paint evenly. Ensure you are using the correct application technique for the chosen tool (brush/roller).
Preparation:
Ensure the surface is free from loose paint, dirt, and grease. Minor dampness is ideal for application; however, if the surface is bone dry, lightly mist it with water before applying the paint. For very porous surfaces, a mist coat may be beneficial.
Application:
Stir the paint thoroughly before use. Apply a thick, even coat using a brush or roller. Ensure complete coverage over the stained or damp area. Allow to dry as per instructions before applying a topcoat.
Compatibility:
This paint is suitable for use on most interior surfaces including plaster, masonry, and previously painted surfaces. It can be overpainted with most emulsion and oil-based paints once dry.
Care:
Store the paint in its resealable tin in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the lid is firmly closed to maintain freshness. Clean brushes and rollers immediately after use with water.
