Questions & Answers


What material is this please?


It's a bitumen based product 


How does this product adhere to a rendered and painted wall? Does the fixing damage the wall?


Hi, how best to fix through onto the wall would be down to the person completely work on site as to not damage the wall. You would then flash over the top of the apron flashing (with Lead or equivalent) to create a water tight seal.

Good quality principal product, with a system of ancillaries that works, and good technical information to back you up. Recommended!

Good, but not so good in being able to appear straight.

Good design, ensures a watertight seam on the apron of a pent-shed. Unfortunately the material of the flashing is not the same type as the roofing sheets. It is a shiny black plastic similar to cheap plastic drain pipe. Although it's "only " a shed, I can't stand the mish mash of materials and wonder why this shape isn't available in the same material as the sheets.
