National Super Matt Emulsion: Coverage, System and How Much to Buy

Bedroom with smooth matt painted walls

Short answer: National Super Matt Emulsion is a water-based acrylic emulsion with a smooth matt finish for interior and exterior concrete, plaster, masonry, brickwork, gypsum and wood. National’s system is one coat of Acrylic Primer (W.B.), one coat of Stucco Filler indoors, then two coats of Super Matt. It covers about 8.5 to 10.5 m² per litre, recoats in 2 to 4 hours at 30°C and thins 5 to 10% with water.

Super Matt or Matt Emulsion?

On paper the two share solids (42%), coverage and drying. The differences are the resin and the system around them:

Step 1: prepare the wall

  • Make the surface clean, dry and sound. Outside, National’s guide gives high-pressure washing at 2200 psi or more; inside, brush off dust and loose material.
  • Remove laitance on new concrete and any efflorescence, both of which the guide says weaken adhesion.
  • Repair cracks with Joint Filler; seal open blocks with Block Filler.

Step 2: the system

  1. Acrylic Primer (W.B.), one coat. It is National’s alkali-resistant primer for interior and exterior concrete and plaster.
  2. Stucco Filler, one coat, interior only.
  3. Super Matt Emulsion, two coats, 2 to 4 hours apart at 30°C.

What the numbers mean

Coverage = 420 ÷ 40 = 10.5 and 420 ÷ 50 = 8.4 m² per litre. Wet film for a 45-micron coat ≈ 107 microns (45 ÷ 0.42), in the middle of the sheet’s 95 to 120 range.

Mistakes to avoid

  • Swapping in a PVA primer. National’s Super Matt system specifies Acrylic Primer (W.B.).
  • Thinning more than 10%. The sheet allows 5 to 10%.
  • Using Stucco Filler on exterior walls. It is interior only.
