Lime Pointing ~ Summer 2008

In what seems to be an annual event, I’ve restarted repointing the exterior of the barn.

When working with lime you have to take a break over the cold, wet winter months – it’s taken me this long to get restarted.

This time, I’ve taken a more scientific approach and attempted to work out how longs it’s going to take.

Last weekend I managed to hack / rake out the old pointing from an area 180cm by 190cm = 3.42m2…that took me just around 3.5 hours, so my hacking out rate = 1 square meter per hour.

I reckon my repointing is slightly quicker – perhaps 45 minutes a square meter. Add to that preparation of the fresh lime mortar taking one hour for every five hours pointing and final cutting back and tidying up of 15 minutes a square meter.

With a total of around 70m2 to complete that works out as:

hacking out rate = 1 hour x 70m2 = 70 hours
repointing = 45 minutes x 70m2 = 52.5 hours
mortar preparation = 52.5 hours / 5 = 10.5 hours
finishing = 70m2 * 15 minutes = 17.5 hours
Total = 150.5 hours

Better stop writing about it and get on with it…
