Introduction

Understanding Damp Walls & Ceilings After a Leak

Whether it’s a burst pipe, roof issue, or plumbing mishap, leaks can saturate walls and ceilings leaving them vulnerable to mould, salts, and flaking paint. Waiting for a full dry‑out can take weeks or longer, delaying your refurbishment.

Why Conventional Paints Fail

Standard paints can’t adhere properly to damp substrates; they seal in moisture, leading to bubbling, peeling, and discolouration. This forces multiple repaints and prolonged restoration.

SPO Anti‑Damp Paint: The Go‑To Solution

SPO Anti‑Damp Paints oil-based formula includes a hydrophilic additive that reacts with incoming moisture, helping the paint bond more securely to the damp substrate.The paint’s microstructure allows moisture to dissipate gradually preventing pressure building. It also contains a built-in biocide to inhibit mould growth.

How to Paint Damp Walls and Ceilings After a Leak

Surface Prep

  • Stop the Leak: Fix the source of water intrusion first.
  • Remove Loose Material: Scrape or sand off any bubbling or peeling paint.
  • Surface Check: Walls & Ceilings should be damp, not soaking. If pooling water is present, wipe away excess.
  • Optional Mould Treatment: If mildew or mould has formed, treat with a fungicidal remover like Fluxaf Mould Remover.
  • Filler (optional): If needed, fill any damaged or uneven areas with a suitable wall filler to ensure a smooth finish.

Application

  • Stir Well: Mix SPO Anti‑Damp Paint thoroughly.
  • Apply in Thin Layers: Use brush, roller, or spray to achieve an even coat—avoid heavy pooling.
  • Allow 12 Hours: Let the anti‑damp layer cure before applying a breathable topcoat.
  • Cleanup: Use white spirit to clean rollers or brushes after painting.
