1. What is SPO Shellac Stain & Odour Blocker used for?

SPO Shellac Stain & Odour Blocker is a powerful, shellac-based primer designed to lock in tough stains—such as nicotine, tar, and water damage—and seal away persistent odours, all while allowing for quick drying and immediate overcoating.

2. Can I use this primer on multiple surfaces?

Yes. It’s suitable for a variety of substrates, including timber, plaster, cement, certain plastics, and brickwork. Always ensure the surface is clean, dry, and free of loose material before application.

3. How long does it take to dry?

The shellac-based formula typically dries in about 30 minutes. You can apply a second coat or your chosen topcoat once the primer is fully dry, speeding up project timelines.

4. Does it really block odours and stains?

Absolutely. Shellac is known for its excellent sealing properties. It prevents bleed-through of water rings, pen oils, nicotine, and other stubborn stains, while also locking in odours like smoke or mustiness.

5. Can I use this product outdoors?

Yes, SPO Shellac Stain & Odour Blocker can be used on both interior and exterior surfaces. For outdoor projects, ensure you follow up with a suitable exterior paint or protective coating.

6. How do I apply it?

You can use a brush or short pile roller. Apply a thin, even layer for the best adhesion. If needed, lightly sand between coats to maintain a smooth finish before applying the topcoat.

7. What coverage can I expect?

Coverage is around 10 m² per litre, though this may vary depending on the surface’s condition and porosity. Prepping surfaces thoroughly helps optimise coverage and sealing performance.
