Bathroom and kitchen walls face steam, splashes and regular cleaning. Short answer: National Paints’ specifier lists five wall systems for these rooms. Wall Rock is epoxy-based with a polyurethane topcoat. Nationaltile and Acrylic Rock are water-based texture systems with a hard topcoat. Eco ends in gloss emulsion, and the alkyd system ends in synthetic enamel. Each is listed below.
The five systems
| System | Primer | Middle coats | Topcoat |
|---|---|---|---|
| National Wall Rock (epoxy) | National Guard Primer for Cement, clear or white (1) | National Interguard H.B. spray texture (1) | Nationalthane or National Polyurethane (2) |
| Nationaltile (water-based) | PVA Primer White, Acrylic Primer or Tex Primer (1) | National Nutex spray texture (1) | Nationalthane or National Polyurethane (2) |
| National Acrylic Rock | PVA Primer White, Acrylic Primer or Tex Primer (1) | National Nutex spray texture (1) | Acrylic Rock Top Coat (2) |
| National Eco | PVA Primer White, Acrylic Primer or Tex Primer (1) | National Nutex spray texture (1) | National Weather Resist or National Gloss Emulsion (2) |
| Alkyd | PVA Primer Sealer or PVA Primer White (1) | Stucco Filler (2), Synthetic Undercoat (1) | Synthetic Enamel Gloss I/II or Flat/Matt Synthetic Enamel (1) |
How to choose
- Smooth, painted look: the alkyd system is the only one here without a spray texture coat.
- Tile-effect finish: Wall Rock, Nationaltile, Acrylic Rock and Eco all use a spray texture coat under the topcoat.
- Polyurethane topcoat: Wall Rock and Nationaltile both finish in Nationalthane. Nationalthane is a two-pack product, mixed 4:1 with an 8-hour pot life at 30°C, according to its data sheet.
The specifier does not rank these systems against each other, so for a project specification, confirm the choice with National Paints or your consultant.
Frequently asked questions
Can I just use emulsion in a bathroom?
Matt and eggshell emulsions are not among the bathroom and kitchen systems in the specifier. For dry rooms, see the interior wall system.
What about bathroom doors?
The specifier has a separate alkyd system for doors and frames. See National wood finishing systems.
