We have spent the last three days putting up the Fermacell sheets on the walls of the garage. Virtually all four walls of the front half of the garage is covered now.
We started using 38mm staples but decided to switch to the shorter 25mm staples as they seem to be holding just as well and the majority of the thickness (made of 18mm OSB and 10mm Fermacell) is only slightly deeper than 25mm! it is working very well so far.
Next we will have to fill in the staples holes and the joints between panels, we did a small test today and we are wondering if the filler supplied by the Fermacell people is the same as Polyfilla. We are planning to do further tests to find out.
The technique of snapping the boards at the cut line seems to be working ok as long as the “waste” piece is large enough to bend in one piece without breaking into smaller pieces. Just a quick wipe with the Surform to smooth off the slightly ragged edge and that is it. No flying dust from a circular saw! Thank goodness!
The boards are very flat and very regular in thickness and are joining together very well. It is looking good! Can’t wait for the finished article!
