Are you looking to improve the performance of your cement render and plaster? LANDU offers a range of high-quality cement render additives designed to enhance adhesion, crack resistance, and overall durability. As a leading manufacturer of construction chemical additives, we provide effective solutions tailored to your specific needs. Let's explore our top 4 additives to transform your cement render projects.

LANDU Construction Additives Enhance Cement Render Performance

What is Cement Render?

Cement render (also called plaster) is a mortar mixture made of cement, sand, water, and special additives like cellulose ethers. Builders apply this mixture to surfaces such as brick, concrete, or stone. After application, people often texture or coat it to make it look better or protect it more. While many use cement render on outside walls, it can also work great for indoor designs.

LANDU Additives - Reinforce Your Cement Render

To serve customers better, LANDU has created several specialized brands. Here's what each one offers for your cement render projects:

LANDERCOLL Cellulose Ethers for Better Cement Render

LANDERCOLL, our core cellulose ethers brand, makes reliable cement render additives like Hydroxypropyl Methyl Cellulose (HPMC) and Hydroxyethyl Methyl Cellulose (HEMC). These work as essential thickeners and water-retaining agents in your cement render mix. Benefits include:

  • High water retention rates
  • Excellent wrapping properties
  • Reduced bleeding in the mortar
  • Improved workability during application

All LANDERCOLL products follow strict REACH regulations for safety and quality.

ACCURATE Redispersible Latex Powder for Flexible Cement Render

LANDU ACCURATE provides high-quality redispersible polymer powder (RDP) that makes cement renders perfect for both indoor and outdoor use. This cement render additive improves:

  • Adhesion to difficult surfaces
  • Flexibility in changing temperatures
  • Resistance to cracking
  • Water retention for proper cement hydration

Our RDP meets strict ASTM standards for construction materials.

NOVASTAR Specialty Additives for Advanced Cement Render

LANDU NOVASTAR represents our innovative expansion into more specialized cement render additives. This line includes premium functional additives such as:

  • Polycarboxylate Superplasticizer
  • Gypsum Retarders
  • Silicone Hydrophobic Powder

For example, NOVASTAR Hydroxypropyl Starch Ether works as both a thickener and stabilizer in cement render. It ensures smooth application and longer open time. By improving mortar consistency, it helps performance on vertical surfaces while maintaining strength.

4 Critical Additives That Transform Cement Render

Choosing the right additives is crucial for achieving the best cement render performance. Here are four essential cement render additives from LANDU:

Hydroxypropyl Methyl Cellulose (HPMC)

LANDERCOLL HPMC comes from refined cotton and works as a non-ionic cellulose ether material. This powerful cement render additive offers excellent water retention, preventing rapid water evaporation in your cement plaster. This ensures complete cement hydration for stronger, more durable results.

HPMC also significantly increases cement render viscosity, making it easier to apply on vertical surfaces without sliding off. This helps ensure smooth construction progress and high-quality finished projects.

Advantages of HPMC in cement render:

  • Enhanced Water Retention
  • Improved Sag Resistance
  • Extended Durability

Hydroxyethyl Methyl Cellulose (HEMC)

LANDERCOLL HEMC works as a non-ionic, water-soluble cement render additive. As an effective water-retaining agent, HEMC extends the workable time of your cement render mortar during construction. This gives workers plenty of time for application, leveling, and finishing, ensuring better results.

For pump-applied cement renders, HEMC improves pumpability by:

  • Reducing flow resistance
  • Minimizing pipe clogging risks

Additionally, it creates an optimized transition zone between the render and substrate, improving both physical and chemical bonding for stronger adhesion.

Advantages of HEMC in cement render:

  • Enhanced Adhesion Strength
  • Excellent Water Retention
  • Improved Workability
  • Enhanced Pumpability

Redispersible Latex Powder (RDP)

LANDU ACCURATE Redispersible Latex Powder works as a powerful cement render additive. Acting as a binder, RDP works together with cement to boost the bond strength between your cement render and the surface underneath. This helps prevent common problems like:

  • Hollowing
  • Cracking
  • Delamination (separation from the wall)

The result is better long-term stability for your cement render project. Moreover, RDP gives excellent alkali resistance to cement render, helping it maintain performance even in highly alkaline environments. This prevents degradation and powdering, effectively extending the service life of your render.

Advantages of RDP in cement render:

  • Enhanced Adhesion
  • Improved Flexibility
  • Better Workability
  • Extended Service Life

Hydroxypropyl Starch Ether (HPS)

LANDU NOVASTAR Hydroxypropyl Starch (HPS) is a fine powder made from highly modified natural polysaccharides. When mixed with water, this cement render additive forms a network structure that spreads evenly throughout the cement mortar. This improves viscosity and cohesion, preventing sagging for more even application.

HPS also adds lubricity, reducing friction with tools and surfaces. This ensures:

  • Smoother troweling
  • Improved workability
  • A refined, crack-free finish

Benefits of HPS in cement render:

  • Effective Thickening
  • Better Workability and Smoothness
  • Superior Finish Quality
