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.

Устойчивост на напукване

RDP polymers absorb stress and improve impact durability.

Adhesion Versatility

Excellent grip on concrete, masonry, and lightweight substrates.

Flexibility and Strength for Demanding Applications

A high‑rigidity polymer designed to reinforce adhesion and toughness in exterior base coats. RDP 5011N forms elastic polymer films within the cement matrix, enabling it to absorb substrate movement and boost bonding performance.

Ключови предимства:

✓ Outstanding crack bridging and impact resistance
✓ Stronger bonding to dense or aged substrates
✓ Enhanced weather durability and long-lasting surface protection

Hydrophobic Powder

SHP‑75

Water Repellency and Efflorescence Prevention

Ultra‑fine hydrophobic agents provide strong water repellence, blocking capillary absorption and reducing salt migration within the plaster layer.

Ключови предимства:

✓ Cleaner surface appearance and color stability
✓ Reduced damp patches, staining, or blooming
✓ Increased durability in humid or coastal conditions

Water Reduction with Upgraded Flow Performance

Advanced polycarboxylate ether (PCE) chemistry improves fluidity, density, and compaction without additional water, delivering high performance for modern rendering systems.

Ключови предимства:

✓ Higher compressive strength and surface hardness
✓ Improved pumpability for mechanical spray or flow applications
✓ Excellent compatibility with HPMC for balanced rheology control

Прах за деаериране

P200

Achieve Smooth and Defect‑Free Finishes

Designed to release entrapped air during mixing, P200 prevents voids, pinholes, and weak zones in cementitious coatings and renders.

Ключови предимства:

✓ Denser structure with improved compressive strength
✓ Uniform, blemish-free surface texture
✓ Optimized strength‑to‑weight performance

Our R&D and Application Support Center offers complete assistance—from formulation optimization, mix testing, and lab analysis (MVR, SIS, and DSC) to on‑site training. Every customer receives expert consultation for consistent results across regions.

Is there a way to test the additives before bulk purchase?

Отговор:

Yes. Join the LANDU Free Sample Program to evaluate compatibility in your own mortar mix. Each sample package includes 200–600 g of chosen additives, detailed datasheets, dosage guidance, and direct feedback from our technical team.

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

Отговор:

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?

Отговор:

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.
