PRATIX® HP 30

PRATIX® HP 30 is a cement-based, fibre-reinforced fine plaster mortar prepared for manual application on interior and exterior surfaces. It is used for levelling surfaces that have received a base coat, for repairing existing plasters and for thin-layer plaster applications.

Complies with class GP CS III W1 according to EN 998-1.
GP: General purpose rendering and plastering mortar
CS III: Compressive strength class
W1: Reduced capillary water absorption

Areas of Use
•    For levelling base-coated surfaces and repairing existing plasters
•    For plastering and repairing concrete, brick and similar surfaces indoors and outdoors
•    For wall and ceiling plasters
•    For repairing joints in natural stone, brick and masonry walls

Advantages
•    Easy to prepare and apply
•    Does not sag on vertical surfaces and provides high adhesion
•    Long working time
•    Produces a smooth, paint-ready surface in a thin layer
•    Resistant to freeze-thaw cycles
