Technical Datasheet
Description:
PROREND PREP Basecoat is very suitable for levelling and renovation indoors and outdoors on mineral and synthetic resin bound backgrounds. PROREND PREP Basecoat can be finished with PROREND decorative renders, Silicate Paint, or PROREND thin or decorative renders. PROREND PREP Basecoat is also suitable as background for tiling.
Composition:
High-quality, factory-composed dry mortar according to DIN 18557 and 18550. Fineness and grain composition of the sand according to DIN 4226, part 1, grain composition 0 - 1.5 mm. Binding agent according to DIN 1060 and 1164 and approved additives, e.g. alkali-resistant reinforcement fibre, for better workability and obtaining the desired qualities.
Characteristics:
PROREND PREP is a smooth render, easy to apply by hand or machine. PROREND PREP Basecoat has very good bonding after drying, is vapour-permeable and water-repellent.
Colours:
Grey

Design, preparation and practical application of external rendering and internal plastering - part 1, external rendering, should be followed at all times.
Sitework:
Scaffolding must be independently tied, to allow uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified.
Site Conditions:
Temperature range, 5-300C. PROREND PREP Basecoat must not be applied to frozen or thawing supports. If the coating must be applied in adverse weather conditions, it is essential to protect both the working area and finish before and after application.
Substrate:
Background has to be free from dust, loose particles, damp and other pollution which can be of disadvantage to the bonding. Supporting, mostly hydraulic backgrounds like old render layers and old well-fixed decorative renders are suitable backgrounds. Do not apply PROREND PREP Basecoat on pure lime renders and backgrounds with intermediate lime laye
