Yesterday and today, we have been preparing and starting the process of putting on a fibre glass resin surface on the insides of the Downpipe Channels. Yesterday, we filled in all the right angle joints with filler to make a smooth curved transition so the glass fibre can fit more easily.

This morning, we rubbed all the filler to take off any sharp bits and then started the glass fibre coating. The first layer was a medium grade glass fibre mesh to provide the core strength to bind and reinforce the resin, and this was followed by a second layer, just on the bottom base board, is a tissue glass fibre to smooth out the ripples.

We then waited for the resin to set a bit then trimmed all the excess fibreglass off and sanded thing smooth.

Tomorrow, we will give the whole thing a final layer using a special “top-coat” resin, in a solid black colour, this will give us our glossy smooth finish inside our guttering to encourage the rain water to flow nicely down to the plastic pipe and beyond.
