Fold the second fabric layer and expose the underside portion, the cement and acrylic is now easily and quickly applied to this area.
Replace the second layer and apply cement and acrylic to complete the rain gutter.
Clean the edge where the fabric reinforced cement reaches the work table surface. Mix a little more cement and make patches using loose fiber, if necessary. Excess can be trimmed with a sharp knife after 6 - 24 hours.
The first test of this rain gutter mold was on the other side of the test house. The rain gutter was made in place, on the structure. As fate would have it, the rains came. It was easy to cover this example with plastic when rain occurred. This rain gutter was allowed to cure ten days under a loose plastic cover which allowed a little air entry.
Removal from the mold is easy. Note that the cement and acrylic have been pulled into the matrix during the cure. This surface was originally saturated; even though the acrilic and cement were only brushed from the other side, this area was visually inspected and seen to be grey and wet. This interesting phenomena will be documented with a photo at the next opportunity.
Retail material cost to this point is 75¢ per foot, about US$ 2.25 per Meter.
The next step is actual installation. Start with some method for holding the rain gutter in place. This photo is a temporary brace held away from the wall surface with a small piece of wood 3/4" thick (2 cm).
A small board 30 cm long pinches like a finger from the inside to sustain the mounting brace position outside of the wall.
