Frequently Asked Questions
What coverage does 25kg MultiFinish Plaster provide?
A 25kg bag of MultiFinish typically covers approximately 10-12 square metres at the standard 2-3mm skim coat thickness. Coverage may vary slightly depending on surface porosity and application technique.
How long does MultiFinish Plaster stay workable once mixed?
MultiFinish remains workable for approximately 90 minutes after mixing with water. Professional plasterers recommend mixing smaller batches to ensure adequate working time and avoid waste.
Can I apply paint directly onto MultiFinish Plaster?
Yes, MultiFinish creates a smooth surface that accepts paint and wallpaper directly without additional preparation. Allow the plaster to fully dry and cure before decorating, typically 24-48 hours depending on conditions.
What surfaces can MultiFinish Plaster be applied over?
MultiFinish is designed as a finishing plaster over base coats like Bonding or Browning plaster, plasterboard, and other prepared surfaces. It's not suitable as a base coat and should only be applied in thin 2-3mm layers.
What tools do I need to apply MultiFinish Plaster?
You'll need a hawk, plasterer's trowel, mixing bucket, and clean water for application. A float may be useful for initial spreading, and a spray bottle helps maintain workability during troweling.
