HP 9 PM Lime base plaster Pure Mineral

HP 9 PM lime base-coat plaster, Pure Mineral

Application

HP 9 PM is used as a base coat plaster. HP 9 PM is particularly suitable for use in (natural stone) cellars. On highly absorbent substrates (Poroton etc.) only after the absorbency has been reduced accordingly (application of a spatterdash, thorough pre-wetting etc.) As a rule, however, the natural lime base coat plasters HP 9 or HP 9 L are recommended here.

Composition

HP 9 Pure Mineral (HP 9 PM) is a purely mineral natural lime mortar. It is composed of natural hydraulic lime, hydrated white lime, quartz sand, expanded glass and silicates. HP 9 PM is free from cement, (methyl) cellulose and organic binders. HP 9 PM is highly vapour-permeable (water vapour diffusion resistance factor µ ≤ 7); its pH value of 11–13 (9–11 in the long term) creates conditions unfavourable to mould growth. Where humidity is permanently high, the cause of the moisture must be remedied and adequate ventilation ensured. HP 9 PM corresponds to mortar class CS I according to EN998-1.
