Category Archives: sand blasting
Now the scaffolding has been removed, we can sandblast the stonework on the new extension. We tend to do the sandblasting at the weekend because it is so noisy and messy. It just makes it to difficult to work on the site while the sandblasting is going on.
The next stage will be to point the stonework. We will be using the same lime and Nosterfield River sand mortar that we used on the original part of the property.
All of this stone has been brought in from offsite and is the closest match the we could find. The one exception are the quoins (the large corner stones) on the porch. These originally form part of the barn that was where the kitchen is now.
With the plasterers due to start on Wednesday this week, I am trying to get a protective coat of liquid wax onto the old oak beams. This means that if anything gets spilt on them, then it should simply wipe off. We sand blasted this oak beams when we cleaned the outside stone, so the timber is very absorbent and anything that gets spilt on them will be soaked up straight away.
I really wanted to keep the light colour of the sand blasted oak, but unfortunately everything that I looked at caused the oak to darken. In the end, I have opted to use Osomo PolyX. This seems to get some great reviews and will hopefully protect the timber. It is expensive though and painting all of the timber is time consuming. It looks as if the next two days are going to be spent painting!
With the windows all installed, our attentions have moved to getting the openings sorted out for two pairs of large doors at the rear of the house. I always knew that there were big (particularly after having seen the quote for supplying them!), but I hadn’t realised quite how big until I saw the openings – each door is over a metre wide.
The ashlar surrounds for the window at the rear and the two openings for the doors was around £3,000 (just for the materials).
Where openings have been walled up, there are now some stones that need to be sandblasted. It just mean getting the sandblaster out again, but he is relatively local and doesn’t seem to mind. It shouldn’t take long to sort out these odd patches.
The gas board have also disconnected the gas supply so that we can move the pipework at the front of the house. This leaves black marks on the stonework where the sandblaster could get to the stonework as the pipes were in the way. This can all get picked up when he comes back.
The windows are all in and they are covered on the inside with some lightweight plastic to protect them while the inside of the property is being plastered.
With the sandblaster back on site at the weekend to clean the newly rebuilt extension, we have taken the opportunity to get the outbuildings (aka shed) sandblasted too. This will help it fit in with the main house. The photos below show the before and after pictures.
Now the stonework on newly rebuilt extension is complete, we need to get it sandblasted. This needs to be done before the new windows are installed on Monday – as part of the sandblasting process we are cleaning the stone window frames removing any signs of the previous windows.
As well as sandblasting the new extension, we have also taken the opportunity to remove any marks where the scaffolding had been. Due to the scaffolding poles being so close to the building, there were patches where we couldn’t clean the building until the scaffolding had been removed. We also sandblasted the old outbuilding. This had some of the darkest stone on site and no longer looked as if it were part of the same set of buildings anymore.
This was a long day – from lunchtime through to 8:30pm. I was glad when it was all over. But the end result looks great.
And the house looks very different. The rebuilt extension is going to be sandblasted tomorrow (Saturday) afternoon. We are doing the sandblasting at the weekend since it isn’t really possible for anyone to work on site while the sandblaster is working.
The new windows are being installed on Monday, so there is quite a bit of work to be done this weekend in preparation.
The roofing felt and lathes are now in place on the rebuilt extension. Tomorrow the stone slates will be replaced and with any luck the roof will have been completed by the end of this week. It will make a big difference.
The sandblasting of the extension is planned for the weekend so that we can get on with the pointing of the extension next week.
Well, 7:30pm on Sunday evening and it is all done. Front, back, chimneys, timbers, and 3 fireplaces. It took around 45 bags of sand (each 25kgs) to complete the work. That’s a lot of sand, but I will leave you to do the maths!
It now looks superb, but it isn’t something that I would want to do every weekend!
All the window reveals were cleaned of as much mastic as possible and then cleaned so that the windows can be installed. The old windows were not set equally – some were further out than others – we will fix this issue when fitting the new ones. This is why all the window reveals needed to be cleaned.
The newly rebuilt chimneys were also sandblasted. Dragging all the tubes around isn’t easy work, but it only took 30-40 minutes to sandblast the chimneys. They do look superb.
I will post pictures of sandblasted timber and fireplaces later.
It is going to take a couple of days to sandblast the outside of the property, the fireplaces (x3) and the oak trusses and purlins in the roof. This work is being done at the weekend, so that it doesn’t interrupt any of the building work – no one can really work on site while the sandblasting is going on due to the noise and dust.
Proceedings didn’t start until just after lunch, but by 4:30pm the rear and one side of the property had been cleaned including one of the fireplaces. The idea is to gently lighten the stone and remove some of the black grime and soot that has built up over the last couple of hundred years. This dark outer layer keeps moisture out, so once the stone has been cleaned, it will need to be treated with a sealant.
The outside of the house, the oak roof trusses and the fireplaces are due to be sandblasted this weekend. This also includes the new rebuilt chimneys. There is a lot to get read in the next four days:
- All the oak trusses and purlins need to be re-installed. To be able to do this, the internal wall that holds up the purlins needs to be rebuilt;
- All the windows (upstairs and downstairs) need to be removed as the stone reveals need to be sandblasted before the new windows can be installed;
- The new ashlar stone surrounds for the windows and doors need to be installed. Some of the existing stone surrounds are modern concrete (called “ArtStone”) replacements. These are being removed and replaced with the real thing;
- Two new chimneys need to be rebuilt. One will be using the existing stone, the other will use the stone from the old porch.
