De-rendering the stonework – Part 2

It’s been a while since the last update. The nights got shorter and the wind colder and I finally gave up on the stonework for the year some time in November. By that time I had too many indoor things to attend to.

But, things have progressed. The side wall stonework has been prepared ready for repointing. This took a few full days to do and required the use of an air hammer and sharp chisel bits.
The beauty if the air hammer over the SDS roto stop drill I had been using is that it is much lighter, much easier to twist about and actually very powerful. It did mean tiny bits if render flying around, and lots of noise, but it worked.

The mortar around each stone needed to be raked out by 40-50mm to allow enough depth for the new pointing to sit tight. Any less and it wouldn’t really have enough strength to it.

The above picture is before I tidied up around the door, the red bricks look really rustic! The lintel will be repaired and painted.

The channel down the side of the house has been dug out, and I will continue to dig lower to make sure rising damp is out of the question.

Here I have tidied up around the sky dish, luckily I have not had to remove it so far. You can also compare the front of the house, which still has the old mortar and bits of render on, with the side.
The entire side has also been washed and scrubbed down with the strongest brick acid I could find. Resulting in quite an angry green bubbly reaction on the concrete smeared stones. They look better for it!
Be careful with this stuff, it smells very strong, you don’t want in on your skin, in your eyes or up your nose, goggles and gloves at all times. I also found it kills the hand held trigger spray guns! I restored to brushing it on the stonework with an old dustpan brush.

Unfortunately the tarmac around the edge of the channel has become quite loose, going to need something to tidy this back up with before I fill the channel with something with good drainage. It’s nearly a foot deep in places. I could lose a kid down there.

With the Easter bank holiday approaching I am looking to get the side of the house repointed. Having not done this before I have spent the last 3 months researching on the net/youtube.
Stay tuned
