Can I use Rubba-Roof to repair leaking abutments, flashing, valley gutters?
Rubba-Roof Professional is self-flashing and can be used to create upstands. In such cases the angle between the vertical and horizontal surfaces should be over-banded with a 300mm scrim reinforcement. This should be embedded into the first coat as it is applied, and carefully rolled to prevent creases and bubbles. The scrim should be installed 150mm up the vertical and 150mm on the horizontal. Apply 2 coats of Rubba-Roof Professional. Alternatively a cant strip or cover fillet can be installed at the vertical/horizontal joint in order to reduce the membrane stresses at a right angle.
