FAQ
Frequently Asked Questions
No, hardwall is an undercoat or basecoat plaster. It is applied first to provide a level surface and key for the final, smoother finish plaster (skim coat).
No, it is not recommended. Hardwall is designed for high-suction backgrounds like brickwork and blockwork. Plasterboard requires specific board finish or multi-finish plasters.
Its primary advantages are high impact resistance, quick setting time, and good adhesion to masonry surfaces, making it a durable undercoat.
No, it is much less common. American English tends to use terms like 'bonding plaster', 'basecoat plaster', or 'setting-type compound' for similar materials.
