Introduction

Understanding Odours

Smoke residue, pet urine, and damp can create lingering odours that standard primers cannot fully neutralise. Even if the stain appears covered, the smell might seep back through over time.

Why Conventional Paints Fail

Odours from smoke, pets, or mildew can embed into surfaces and often resurface through ordinary paints. This leads to persistent, unpleasant smells even after repainting.

SPO Shellac Stain & Odour Blocker: The Go‑To Solution

With its shellac base, SPO Shellac Stain & Odour Blocker permanently encapsulates the source of odours. This prevents re‑emergence and leaves your space smelling fresher and cleaner for the long haul.

How to Block Odours

Surface Prep

• Clear away any debris or old residue
• thoroughly clean all areas effected
• Ensure the surface is fully dry
• Lightly sand glossy areas for better adhesion

Prime

• Stir SPO Shellac Stain & Odour Blocker before use
• Apply a thin, uniform coat with a brush or short pile roller
• This paint dries extremely quickly, so work fast. Avoid leaving the tin or brushes exposed to prevent them from drying out
• Methylated spirits will be needed to clean any tools used

Recoat

• Once dry, check if any smell lingers
• If needed, add another layer
• Finish with your chosen paint

One side remains untreated, clearly showing the stain bleeding through the topcoat, while the treated side displays a clean finish, with the smoke stain fully sealed and odours neutralised.
