Can Impermax be used on pitched roofs?
Pitched roofs/ flat roofs/ old felt roofs, when combined with a selection of the correct primer allows Impermax to be applied to most surfaces. PU Primer for non absorbent, and Humidity Primer for absorbent substrates.Impermax is self levelling, but with the addition of Thixotropic agent removes the self levelling properties of Impermax and allows it to be applied to up-stands and slopping roofs.
