Product Description
Adhesive and Reinforcing Mortar Lightweight -EPS- is a high-yield, factory-made, water-repellent, mineral dry mortar based on white cement, mortar group P II according to DIN V 18550, CS II according to DIN EN 998-1.
Lightweight Adhesive and Reinforcing Mortar -EPS- is suitable for bonding organic (e.g., polystyrene) and mineral insulation boards (e.g., mineral wool boards), as well as for embedding reinforcing mesh onto insulation boards, especially for External Thermal Insulation Composite Systems (ETICS). Furthermore, it is suitable for reworking sound or appropriately pre-treated existing plaster, cracked plaster facades, or as a plaster bonding agent on smooth concrete surfaces, grooved and rough XPS boards (Styrodur), wood wool boards, etc., for the subsequent application of lime, lime-cement, or cement plasters.

Composition
Graded and dried carbonate or silicate natural sands
White cement
Hydrated lime
Organic lightweight aggregate (EPS)
Additives to improve workability, adhesion, and water repellency

Technical Data
Water requirement: approx. 6 L per bag
Yield: approx. 1100 L/t
Water absorption coefficient: w ≤ 0.5 kg/m²h⁰·⁵
Compressive strength: approx. 3–4 N/mm²
Adhesive tensile strength: > 0.08 N/mm²
Water vapor diffusion resistance (µ): ≤ 20
Thermal conductivity: approx. 0.37 W/mK
Fire classification: A2 (non-combustible)
Packaging: 25 kg paper bag, 21 bags per half pallet
Storage: Dry, protected from moisture

Substrate Requirements
The substrate must be clean, dry, firm and load-bearing, and free from efflorescence and separating agents. Test adhesion on critical substrates, remove loose plaster and paint residues, and roughen and clean smooth-surfaced insulation boards (especially XPS).

Application
Can be applied using plastering machines, continuous mixers, or manually (one bag with approx. 6 L of clean water, stirred lump-free, short maturation, then remixed). Bond boards using the perimeter bead + dot method or the full-surface method (depending on system approval). Do NOT apply adhesive into board joints.
