Nutex is the texture coat in several of National’s best-known wall systems. Short answer: National Nutex is a water-based copolymer emulsion with fine quartz aggregate, sprayed or rolled in one coat for a light, medium or heavy texture. It covers about 1.3 to 2.6 m² per litre and needs at least 24 hours before topcoating, according to National’s data sheet.

Frequently asked questions
Nutex or Texo Compound?
Both are National intermediate textures for the same systems. See our Texo Compound guide for how the data sheets differ.
Can I leave Nutex without a topcoat?
National describes it as an intermediate coat and its system ends with two topcoats. For a texture used as the final coat, see the National Tex range.

|---|---|---|
| Volume solids | 65% | 45% |
| Dry film per coat | 250 to 500 µm | 250 to 500 µm |
| m² per litre | 1.3 to 2.6 | 1 to 2 |
| Colours | White, off-white | Off-white |
| Application | Spray gun or roller | Spray gun |
| Topcoat after | 24 hours | 24 hours |
Step 1: prepare the wall
- National’s surface preparation guide calls for high-pressure water washing (2200 psi minimum) on exteriors, then a dry, sound surface free of laitance and efflorescence.
- Prime with PVA Primer White or Acrylic Primer (W.B.), as the system lists.
What the numbers mean
Coverage = 65 × 10 ÷ 250 = 2.6 and 65 × 10 ÷ 500 = 1.3 m² per litre, exactly the sheet’s range. A heavy texture uses twice the material of a light one.
| Wall area, 1 coat | Light (2.6 m²/L) | Heavy (1.3 m²/L) |
|---|---|---|
| 150 m² (boundary wall, both faces) | about 58 L | about 115 L |
| 400 m² (villa exterior) | about 154 L | about 308 L |
Mistakes to avoid
- Topcoating before 24 hours.
- Thinning it. It is ready for use.
- Changing nozzle or pressure mid-wall. Keep to the sheet’s 60 to 70 psi and one nozzle size per elevation.
