Why HPS is Essential in Adhesive Mortars
Purpose‑engineered Hydroxypropyl Starch Ether grades for every external insulation workflow — from EPS board bonding to reinforced base coat layers — delivering reliable adhesion and superior long‑term durability.
Engineered for expanded polystyrene (EPS) insulation boards in EIFS / ETICS systems. Landu Novastar HPS delivers consistent workability for both dot‑and‑dab and full‑bed coverage methods, ensuring reliable long‑term bond strength across diverse substrate conditions.
Engineered for extruded polystyrene (XPS) boards with low surface absorption. Landu Novastar HPS delivers enhanced bond strength to smooth XPS surfaces, resisting moisture ingress and temperature cycling for long‑term system integrity.
High‑density mineral wool boards demand superior moisture retention for reliable open time and bond formation. Landu Novastar HPS achieves secure bonding and meets fire‑safety standards per ETAG 004 — purpose‑built for demanding fire‑resistant EIFS / ETICS assemblies.
One optimised formulation covers EPS, XPS, and mineral wool insulation systems. Landu Novastar HPS precisely balances adhesion strength and flexibility, delivering consistent performance across the full range of EIFS / ETICS substrates without reformulation.
Applied at 3–5 mm thickness with fiberglass mesh fully embedded, this reinforcing layer delivers outstanding crack and impact resistance across the entire facade system. Landu Novastar HPS ensures a consistently smooth, workable base coat — ready to receive decorative top coat finishes.
Combining adhesive bonding with mechanical anchors, this hybrid system is purpose‑built for high‑rise facades and wind‑load critical applications. Landu Novastar HPS ensures supplementary bonding integrity and long‑term structural stability across demanding building envelopes.
Seven critical parameters where Hydroxypropyl Starch Ether delivers measurable improvement across every stage of the facade system.
Excellent bond to EPS, XPS, mineral wool and substrate — consistent pull‑off strength across all insulation board types.
Smooth troweling and easy board positioning — extended open time allows precise placement without premature set.
Maintains hydration for full cement reaction — prevents premature drying on absorptive substrates and in hot or windy conditions.
Accommodates substrate movement and thermal expansion — the adhesive layer remains intact through seasonal temperature cycling.
Improved rheology combined with fiber synergy reduces shrinkage cracking — maintains surface integrity over the full service life.
Resists UV degradation, freeze‑thaw cycling and rain exposure — long‑term facade performance in all climate zones.
Easy spreading reduces waste and consumption — optimised rheology means less mortar per m² without compromising bond performance.
