British Gypsum Thistle MultiFinish is a go-to finishing plaster in the UK for getting a smooth, paint-ready surface on internal walls and ceilings. It’s designed to be applied as a skim coat (typically over plasterboard or a suitable backing plaster), giving you a fine finish that’s easy to trowel up when the timing’s right. It’s popular because it goes on consistently, can help tidy up minor imperfections, and leaves that clean “new room” look once it’s fully dry and ready for a mist coat.
