Purpose‑built for continuous pump‑spray workflows — delivering consistent rheology under pressure, zero nozzle blockage, and a uniform surface finish at speed. Maximize output without compromising quality.
Machine‑applied plastering uses specialized equipment to mix, pump, and spray plaster onto walls and ceilings — delivering higher output, better surface uniformity, and lower labor costs compared to manual methods.

Why Landu Novastar HPS Matters
Purpose‑engineered grades for every machine plastering workflow — from interior smooth finishes to exterior textured coatings — delivering consistent pump performance and superior surface quality.
For large wall and ceiling areas requiring smooth, high‑quality finishes. Optimised for continuous pump‑spray workflows with consistent layer thickness and zero sag.
For facades and high‑rise projects requiring superior pumpability and long‑term weather durability. Optimised for thicker coats with consistent layer adhesion and zero sag on vertical surfaces.
Engineered for steady, uninterrupted flow through continuous mixer platforms. Novastar‑HPS maintains consistent viscosity from first mix to final spray, reducing downtime and protecting pump components.
Engineered for 15–25 mm thick base coat applications requiring strong substrate adhesion, zero sag, and a perfectly level surface for subsequent finish coats. Consistent performance across concrete, brick, and block substrates.
Two precision‑engineered application types for final‑layer and thin‑film workflows — delivering smooth trowelable finishes, minimal rebound, and fast high‑coverage spray performance.
Engineered for 5–10 mm final layers where surface smoothness and trowelability are critical. Novastar‑HPS ensures consistent spray flow, zero drag, and a flawless finish‑ready surface.
Optimised for fast spray of 5–10 mm films with minimal rebound and maximum area coverage per shift. Novastar‑HPS maintains stable flow and adhesion at high spray speeds.
A structured overview of the six core performance advantages Novastar‑HPS delivers across all machine plaster application types — from pumpability to extended pot life.

Frequently asked questions on dosage, compatibility, pumpability and on‑site troubleshooting for machine‑applied plastering.
0.15–0.35% depending on application.
Interior: 0.15–0.25% · Exterior: 0.2–0.35%
ST1506A is the top choice for most machine applications due to its versatile viscosity range and excellent pumpability.
No. HPS improves pumpability and reduces blockage risk. Blockages are typically caused by poor mixing, lumps, or improper sand gradation.
Use higher viscosity HPS (ST1703A or ST2442) at 0.25–0.35%, reduce water content, and apply proper thickness per pass.
Yes. HPS is compatible with all major brands — PFT, Putzmeister, M‑Tec and Chinese brands. Adjust dosage based on specific equipment.
Reduce spray pressure, optimize water content, increase HPS dosage, and adjust spray angle at 30–50 cm distance.
Typically 2–4 hours in continuous mixers. Can be extended with retarders if needed.
Increase HPS dosage by 0.05–0.1%, add HPMC (0.05–0.1%), optimize water content, and use proper sand gradation.
