1. Depends how big your house is. What is total square meterage of rendering needed? Make sure to deduct openings, ie doors and windows.
2. Depends on height. Is your house 1 or 2 or 3 storeys?
3. Depends on number of openings. Are there big areas unobstructed by windows and doors? Two gable ends? The less the obstruction, the less the corner and stop beads required, the less care needed at edges. Plasterers love big unobstructed areas, it means they came be at home in time for tea.
Give me an idea of the layout of your house in relation to 1-3 above and I'll get back to you with a labour only guide price.
As regards sourcing Weber products or equivalents in Ireland, I'm at a loss. Did a quick online search, but nothing came up. But, I am 100% sure that they are available.
EUR 7.00 a bag sounds good (too good really). We pay around £8.00 sterling for one 25kg bag and we buy in pretty large quantities.
Allow around 1 bag per 1 square metre, by the way.
Coloured beads cost around £0.90 per metre.
Have you thought about what detail you will use at base of wall around house? Has you discussed this with you plasterer?
