Seal‑O‑Damp White Excelsior 1L: Superior Moisture Protection for Masonry Surfaces
Moisture intrusion can compromise the integrity of walls and ceilings, leading to flaking, damp stains, and mould issues. Excelsior’s Seal‑O‑Damp White tackles this head-on with a high-performance acrylic formula designed to seal and protect against both rising and penetrating damp—indoors and out.
Seal‑O‑Damp White Excelsior 1L
Product Overview
Seal‑O‑Damp White is a technologically advanced damp-sealing coat that penetrates masonry surfaces to form a moisture-resistant barrier. It’s ideal for preparing plaster, cement, brick, concrete, and gypsum boards ahead of painting, while also functioning as a moisture-tolerant primer for slightly damp substrates.
Key Features
- Advanced acrylic resins: Hydrophilic acrylics penetrate deep, forming a durable moisture seal.
- Finish and adhesion: Dries to a clear-to-white coat with good opacity, enhancing topcoat coverage and adhesion.
- Substrate compatibility: Works on new or sound surfaces including cement, brick, plaster, and gypsum boards.
- Accelerated paint cycles: Allows earlier painting on damp plaster with low residual moisture.
- Easy application: Use a brush or roller on properly prepared surfaces.

Application Tips
- Clean and repair the surface—remove flaking material and fill gaps.
- Allow new plaster to cure for at least 2 weeks prior to application.
- Apply uniformly using a brush or roller, saturating the surface evenly.
- Wait until dry and visually check for residual damp before topcoating with water-based emulsion paint.
Seal‑O‑Damp is not just a moisture barrier—it’s the foundation for a longer-lasting, more resilient paint job.
