Coverage: Approximately 10 m² per litre per coat (at recommended 35-40 µm dry film thickness)

Coverage per size

• 500ml: Covers approx. 5 m² per coat
• 1 litre: Covers approx. 10 m² per coat
• 2.5 litres: Covers approx. 25 m² per coat
• 5 litres: Covers approx. 50 m² per coat

Recommended coats

• 2 coats recommended for deep, rich finish and optimal opacity
• High opacity formula, but second coat ensures best depth of colour and even finish

Example calculations

• For a 10 m² feature wall, you will need approximately 1 litre per coat
• For 2 coats, you will need approximately 2 litres total (two 1L tins or one 2.5L tin)

• For a 25 m² ceiling, you will need approximately 2.5 litres per coat
• For 2 coats, you will need approximately 5 litres total (one 5L tin)

• For 5 wooden beams (approx. 2.5 m² total), you will need approximately 250ml per coat
• For 2 coats, you will need approximately 500ml total (one 500ml tin)

Practical coverage may be lower depending on surface porosity, texture, and application method. Porous wood or rough masonry may require more paint. For accurate project planning, we recommend ordering 10-15% extra to account for surface variation.

Surface Preparation

• Ensure all surfaces are clean, dry, and free from grease, oil, dust, and contaminants
• On unstable brick, screed, or plaster, apply a masonry stabilizer before painting
• Existing painted surfaces should be cleaned, degreased, and lightly sanded to provide a good key
• Remove any loose or flaking material and treat bare areas as new substrate
• Ensure surface and air temperature is above 7°C (minimum application temperature)
• Provide adequate ventilation during application and drying

Application

• Stir paint thoroughly before use and occasionally during application
• Apply using a good-quality brush or short-pile roller
• Thin with clean water if required (maximum 5% for brush/roller application)
• Apply first coat evenly, working paint well into the surface
• Allow to dry for minimum 6 hours at 20°C before applying second coat
• Apply 2 coats for full opacity, deep colour, and optimal matt finish
• Apply directly to wood, concrete, masonry, and plaster
• On metal surfaces, use SPO All Metals Primer before application
• On tile or melamine, apply SPO Tile and Melamine Primer prior to painting
• Avoid application in damp, humid, or freezing conditions

Drying & Curing Times (at 20°C)

• Touch dry: 30 minutes
• Hard dry: 2 hours
• Recoat time: Minimum 6 hours
• Full cure: 5-7 days (paint will continue to harden during this period)

Drying times may be extended in cooler temperatures or high humidity. Ensure adequate ventilation during application and drying.

Important Notes

• Interior use only (or suitably sheltered exterior use where appropriate)
• Not suitable for wet areas, floors, or heavy-wear surfaces
• Matt finish is not wipeable/washable like satin or gloss finishes
• For best results, apply 2 coats for deep, rich, non-reflective finish

1. What is SPO Matt Black Paint used for?

SPO Matt Black Paint is a water-based coating that creates a deep, non-reflective finish (LRV: 4.1) on a variety of surfaces. It's ideal for wooden beams, ceiling beams, feature walls, chalkboards, photo darkrooms, wrought iron, and any project requiring a bold, ultra-low reflectance matt black finish.

2. What does LRV 4.1 mean?

LRV (Light Reflectance Value) measures how much light a colour reflects, on a scale of 0 (pure black, no reflection) to 100 (pure white, maximum reflection). An LRV of 4.1 means this paint reflects only 4.1% of light, creating an ultra-low reflectance, true matt black finish. This is significantly lower than standard black paints, making it ideal for photo darkrooms, studios, and spaces where glare control is essential.

3. Can this paint be used both indoors and outdoors?

This paint is designed for interior applications. It can be used in suitably sheltered exterior areas (covered porches, protected beams), but is not suitable for fully exposed external surfaces or areas subject to weather. Ensure the surface is clean, dry, and properly prepared to maximise performance and longevity.

4. How do I apply SPO Matt Black Paint?

Apply using a good-quality brush or short-pile roller. Stir thoroughly before use. Ensure the surface is clean, dry, and properly prepared. Apply first coat evenly, allow to dry for 6 hours, then apply second coat. The paint can be thinned up to 5% with clean water if required. Coverage is approximately 10 m² per litre per coat.

5. How long does it take to dry?

At 20°C, SPO Matt Black Paint is touch dry in 30 minutes and hard dry in 2 hours. For recoating, wait a minimum of 6 hours. Full cure is achieved after 5-7 days. Drying times may be longer in cooler temperatures or high humidity.

6. Is it really low-odour and eco-friendly?

Yes. As a water-based paint with ≤30 g/L VOC content, it emits minimal odour compared to solvent-based paints. It's safe for indoor use with minimal ventilation and is easier to clean up with water, making it an eco-friendlier option. Non-flammable.

7. Does it provide good coverage?

Yes. SPO Matt Black Paint has excellent opacity, covering approximately 10 m² per litre per coat. The high-opacity formula (36% volume solids) means fewer coats are required to achieve a rich, uniform finish. Two coats are recommended for optimal depth and coverage.

8. Will the finish remain truly non-reflective over time?

Yes. When applied correctly, the ultra-low LRV (4.1) matt finish retains its deep, non-reflective appearance. Regular dusting and proper maintenance help it stay looking fresh and dramatic for years. The matt surface naturally disguises dust and fingerprints.

9. Can I use this on metal surfaces like wrought iron?

Yes, but metal surfaces must be primed first. Use SPO All Metals Primer before applying SPO Matt Black Paint to ensure proper adhesion and durability. This is essential for wrought iron, railings, and other metalwork.

10. Is this suitable for chalkboards?

Yes. SPO Matt Black Paint creates an excellent chalkboard surface for schools, cafés, restaurants, offices, and homes. The matt, non-reflective finish is perfect for chalk writing and drawing. Ensure the surface is smooth and properly prepared for best results.
