Well, before I load on the photos I will describe the process for the walls. First you need to scrape out as much of the old mortar as possible - yep, did that for the past few weeks! - Then you can either sand blast or pressure wash the stone to clean it. We have gone the washing option. This is a cold and extremely messy job. You end up with mud and water everywhere - including all over the operator. Consequently I did it for about a minute - copped a couple of mouth and eyefuls of muck then left it to the professional - here he is now post pressure washing;
My poor washing machine is getting hammered at the minute! Anyway once you have done that the walls look a bit like this;
There was a repair to one of the lintels needed - so this is Paul with his safety gear on making a new one;
Mmmm - yes once the wall is ready then the fun begins. We are using a mix of four buckets of sand to two buckets of lime based product that is fit for purpose called Renocal - it all goes into the cement mixer - water added until you have a good consistency then we take buckets of the render up the stairs to be applied to the walls. I am saying we here but probably should say he as I can only carry about half a bucket full so it's not worth the bother. Anyway we then using either hands or trowels, get the mix into the joints as best we can trying to leave no holes or air bubbles. We patch the walls with stones along the way where necessary. It's actually quite fun although one of the most efficient ways of getting the mud to stick is throwing it - unfortunate side effect of this is it often cames back to get you - I have had several incidents of lime mortar in my eyes - trust me this aint pleasant. I know you are meant to wear eye protection but it is so hard to keep them on as within a few minutes you can't see through them so they just get chucked off. I haven't taken any shots of the walls after this first process - I will do some this week as we have got a few weeks of this to go, so there will be plenty of chances for it. But usually we are too dirty to be grabbing the camera at this stage.. Anyway once the mud has had a chance to go off - depends a bit on the weather but usually about three hours later - you come along with a wire brush and clean up the stone exposing the wall. You then brush with a banister brush to remove some of the harsher wire brush marks. This can be a bit tricky to get right and we definitely had improved by the time we got to the end of the week. Here is a some pics of the finished walls. It's hard to get a shot to look natural as the flash does strange things to the pic but here it is;

Tomorrow's job ready to go. |
He has also done a bit of pressure washing the stairs and where he has done it they have come up looking great. Water and wood aren't a great mix though so we aren't sure whether it will end up doing any damage to the timber. Paul has been very careful to try and keep the stairs as dry as possible during the wall washing process but it has been hard.
