Redispersible Polymer Powder FWD 5044: The Flexible Solution for High-Performance Mortars

RDP FWD 5044 is a high-performance, water‑redispersible polymer powder based on a vinyl acetate‑ethylene (VAE) copolymer. Engineered with a minimum film forming temperature of 0 °C, it delivers superior flexibility, outstanding adhesion, and excellent crack‑bridging performance. Specially formulated for demanding applications — from high‑grade tile adhesives and waterproofing mortars to EIFS and self‑leveling compounds.

📌 Strategic applications

FWD 5044 is the preferred choice for high‑performance systems where flexibility, adhesion, and durability are critical.

Tile Adhesives (C1E / C2) ★★★★ ★ 1.5‑3 % ( >4 % for high‑demand )
External Insulation & Finish Systems (EIFS) ★★★★ ★ essential
Tile Grouts / Joint Fillers ★★★★ ★ flexible, crack‑resistant
Self‑leveling Compounds ★★★★ ★ flow & cohesion
Waterproofing Mortar ★★★★ ★ flexible membrane
Repair Mortar / Crack Filler ★★★ ★★ adhesion & deformation

🧱 Tile adhesives & grouts

Ideal for large‑format, low‑absorption tiles and heated floor systems. FWD 5044 provides deformation resistance and impact resistance, ensuring bond integrity. In grouts, it delivers flexibility and crack bridging for long‑lasting joints.

💧 Waterproofing mortars

Transforms rigid coatings into a flexible, seamless membrane that follows substrate movement. The polymer film bridges micro‑cracks and provides a durable watertight barrier for roofs, bathrooms, basements, and bridges.
