LANDU — Additives for Cement Plaster & Cement Render

Advanced Performance for Modern Wall Systems

Premium Grade Certified Quality

Complete Solution

From interior finishing coats to exterior façade renders, LANDU Construction Chemicals delivers additive technologies that transform ordinary cement‑sand mixes into stable, strong, and work‑friendly coatings.

Advanced Formulation

Our formulations – a balanced synergy of cellulose ether (HPMC / HEMC), redispersible polymer powder (RDP), hydrophobic powder (SHP), PCE superplasticizer, e defoamer – are engineered to achieve ideal viscosity, adhesion, water retention, and durability throughout every coating layer.

Consistent Results

Whether trowel‑ or spray‑applied, thin‑film or thick render, LANDU additives produce consistent results: resilient coatings, effortless application, and long‑term surface integrity under all climate conditions.

The Role of Additives in Cement Plaster & Render

Traditional Approach

Traditional cement plasters rely purely on water, cement, and sand – a simple formula that often falls short against today's construction standards of durability and finish.

Modern Solution

Additives modify how plaster behaves during application and curing, ensuring a stable, easy‑to‑work material that bonds securely and resists cracking.

With LANDU systems, you can achieve:

✓ Longer open time for large‑area projects

✓ Enhanced cohesion and surface strength

✓ Reduced cracking and shrinkage stresses

✓ Superior workability and smooth finish

✓ Reliable adhesion on diverse substrates (concrete, brick, AAC, and block)

✓ Effective water repellence that prevents efflorescence

Performance Advantages of LANDU Additive Technology

Moisture Retention

Keeps plaster hydrated for stronger bond formation and dust‑free finishes.

Smooth Workability

Controlled viscosity for uniform spreading and steady film build.

Crack Resistance

RDP polymers absorb stress and improve impact durability.

Adhesion Versatility

Excellent grip on concrete, masonry, and lightweight substrates.

Hydrophobic Protection

What is the shelf life and storage requirement for LANDU additives?

Answer:

Most LANDU powders remain fully effective for 12 – 24 months when stored in a dry, cool environment, away from direct sunlight and moisture. Always reseal opened bags tightly to prevent humidity absorption.

How can I order or request samples from abroad?

Answer:

LANDU maintains a global logistics network, with FedEx / DHL delivery to over 60 countries. Simply fill out the online "Request Sample / Contact Us" form—our team will coordinate shipping and technical documentation promptly.

What makes LANDU different from other construction chemical brands?

Answer:

With 20 years of engineering experience, ISO 9001 & EU REACH certifications, and 75,000 tons of annual capacity, LANDU ensures consistency, innovation, and reliability. We don't just supply additives — we build performance into your plaster systems.
