Progress Update – Odpod
We’ve been super busy over the last few weeks. All the internal cut outs are complete upstairs and down stairs. We’ve used over 300, 5” cutting disks 10 tubes of polyurethane sealant to plug up all the gaps. It’s really important to use goggles that completely cover your eyes, good ear muffs, gloves and I’m using a spray painters mask to block all the fine particles. We ended up with heaps of scrap metal, some of it has already been sold by the kg and the rest we will keep to make some raised vegie boxed.
The Sikaflex 11 FC and CRL polyurethane sealant are in 600mm sausages and work really well in a pneumatic gun. I highly recommend buying a gun and an air compressor or a battery powered gun. (otherwise your arms will drop off) We used a roll of foam to fill and large gaps before using any sealant.
Grinding disks can be very expensive, we have had priced from $1.55 to $2.76. The polyurethane sealant ranges in price dramatically, from around $7 to $25 and the quality varies. Sikaflex has a very good reputation but also has a price to suit! (Bunnings were the most expensive in both cases.)
