Professional Hydroxypropyl Starch Ether (HPS) engineered for tile adhesive systems — delivering outstanding bond strength, extended open time, and anti‑sagging performance for reliable tile installations in any environment.
Tile adhesive (or thin‑set mortar) is a cement‑based bonding compound used to fix ceramic, porcelain, and stone tiles on floors and walls. Modern pre‑mixed formulations deliver stronger adhesion and thinner layers than traditional sand‑cement mortar.
Landu Novastar™ HPS
Engineered to elevate every critical performance metric in tile adhesive formulations.
Select the right Hydroxypropyl Starch Ether grade for your adhesive class, substrate, and performance target.

Step-by-step guidance from substrate prep through grouting — plus a quick-reference troubleshooting panel for common field issues.
Clean, sound substrate — concrete must be cured ≥ 28 days. Remove all dust, oil, and loose particles before application.
Add 5–7 L water per 25 kg bag. Mix 3–5 min at 400–600 rpm, rest 10 min, re-mix, then use within pot life 2–4 h.
Trowel adhesive onto substrate and comb with a 6–10 mm notched trowel — select notch size according to tile format and weight.
0.05–0.1 %, or switch to
ST1703A / ST2442 for enhanced anti-sag performance.
