I am yet to see the second render test dried, but am ready to give up on the hope of being able to colour the render with sand alone and will now try some oxides. AHMC advise that the hemp wall need to be wetted before the application of the render, this was a bit tricky for our first render test, but for our second render test I used a garden pressure sprayer, of the type usually used for fertiliser. It worked well giving a fine spray of water that meant it was easy to control the area that got wet and how much water was applied.

Meanwhile with no more usable ply sheets, we worked on the blocking that goes behind the express joints in the main room. Whether it was experience or working in a larger room but the work seemed to be getting easier. I have also accepted that nothing is ever perfectly straight in building and that you need to measure the exact location of where each piece goes and cut it accordingly. When I first started the blocking I had some problems skew nailing it with the framing nailer, particularly pushing the nailer in far enough to fire and getting the right angle. Now I can do this with ease, even using my right or left hand.

There were many subsequent phone calls as the delivery company could not deliver on weekends and could not deliver without us on sit as we had to unload it, so because of other commitments we had that meant we could not be on site on a weekday, our delivery of MgO Boards arrived four weeks after we had originally booked for its delivery.
The MgO sheets are 8mm and did not look too heavy, but looks were deceiving, I was only able to carry one sheet at a time together with another person. Further because the truck was side loading it could not go down the driveway, otherwise there would have been nowhere for it to unload. We started carrying sheets down the driveway one by one. This would have taken a long time as we have a battle axe block. Things were sped along when the delivery boys started using a trolley loaded with four sheets at a time to wheel the sheets to the end of the driveway, from where Ben and one of the delivery boys were able to carry them two at a time into the house.
