1. What is SPO General Purpose Stain Block Primer used for?

This oil-based primer is designed to lock down water, nicotine, grease, and other persistent stains, preventing them from bleeding through into your final paint job.

2. Can I use it on both interior and exterior surfaces?

Yes. It’s formulated for versatile application on walls, wood, brick, and more—whether indoors or out.

3. How quickly can I apply the topcoat after priming?

You can typically apply your topcoat in just 4–6 hours, keeping your project moving forward without lengthy drying delays.

4. Does this primer really stop tough stains from coming back?

Absolutely. Its sealing formula ensures stains are contained beneath the primer, so they won’t reappear or discolour subsequent paint layers.

5. How much area does one litre cover?

The primer covers roughly 10 m² per litre, depending on the surface’s porosity and condition. Applying a thin, even coat helps maximise coverage and sealing effectiveness.

6. What application methods are recommended?

You can apply the primer with a brush, short pile roller, or spray. Make sure the surface is clean and dry for best results.

7. Do I need any special preparation before using this primer?

Remove loose or flaky paint, clean away dirt or grease, and ensure the substrate is thoroughly dry. For challenging stains, applying two thin coats can provide an extra layer of protection.
