Repair Mortar Additives
What is Repair Mortar？
What Are Additives in the Repair Mortar Formula？
Repair mortar consists of cement, sand, lime, and other additives. Common additives include polycarboxylate superplasticizer, cellulose ethers, redispersible latex powder, reinforcing agent, rheology agent, defoamer, and a swelling agent. With decades of experience in specialty chemicals production, LANDU spares no effort to deliver the best solutions and solve clients’ difficulties with repair mortar.
LANDU Additives - Reinforce Your Repair Mortar
With several different brands under LANDU, we are aiming to provide you with a comprehensive chemical additives portfolio to consolidate your repair mortar projects.
LANDERCOLL Cellulose Ethers for Repair Mortar
LANDERCOLL, a core brand under LANDU, specializes in cellulose ether manufacturing. LANDERCOLL Hydroxypropyl Methyl Cellulose (HPMC) and Hydroxyethyl Methyl Cellulose (HEMC) play a vital role in improving the thickening and water retention performance of repair mortar. Meanwhile, they can endow the mortar with better impermeability and durability, ensuring its long-term use.
ACCURATE Redispersible Latex Powder for Repair Mortar
ACCURATE offers high-quality Redispersible Latex Powder to make your repair mortar have better performance in adhesive strength and workability. The powder can seriously advance the bonding strength between repair mortar and old concrete, thereby improving the overall structural strength. Mortar, with the addition of ACCURATE redispersible latex powder, is finer and smoother, easier to level and shape, significantly improving construction efficiency and appearance quality.
NOVASTAR Additives for Repair Mortar
NOVASTAR is a historical innovation of LANDU, marking its entry into more chemical additive areas. Novastar additives for repair mortar include Polycarboxylate Superplasticizer, Silicone Hydrophobic Powder, and so on. They can effectively enhance mortar fluidity and improve the early and later strength of concrete, ultimately leading to an increase in strength.

LANDU NOVASTAR silicone hydrophobic powder, generally abbreviated as SHP, is a powerful chemical additive used in repair mortar for its remarkable water-repellent properties. It is a fine, white powder composed of silicone polymer, known for its unique combination of flexibility, stability, and resistance to various environmental factors. Forming a protective, hydrophobic barrier prevents water penetration and helps maintain the integrity and durability of buildings repaired with mortar.

- Outstanding Hydrophobic Performance: It can significantly enhance the hydrophobicity of repair mortar, making its surface less likely to be wetted by water.
- Good Durability: By reducing the damage of moisture to the internal structure of mortar, it can help prolong the lifespan of the construction.
- Anti-Water Penetration: It forms a waterproof barrier on the surface of the mortar, which prevents liquid water from penetrating into the interior of the repair mortar through capillary action.
LANDU LANDERCOLL Hydroxypropyl Methyl Cellulose(HPMC) is a non-ionic cellulose ether derived from refined cotton. It has an excellent thickening effect, which can significantly increase the viscosity of mortar, improve workability and adhesion, and make it easier to apply. In addition, HPMC has an extremely strong water retention capacity, which can effectively reduce the loss of water in mortar, prevent the formation of cracks, and extend the open time.
- Excellent Thickening Effect
- Enhanced Water Retention
- Improved Workability
- Increased Sag Resistance
- Extended Open Time

| LANDERCOLL K40HT | 0.2-0.5% | Download TDS |
LANDU LANDERCOLL Hydroxyethyl Methyl Cellulose(HEMC), also known as Methyl Hydroxyethyl Cellulose(MHEC), is a non-ionic, water-soluble cellulose ether. It has good water retention and thickening properties, and can effectively improve the working performance of repair mortar. After adding HEMC to cement mortar, the water loss of the mortar during the mixing and construction processes can be significantly reduced, maintaining the moist state and plasticity of the mortar.

- Excellent Water Retention
- Good Dispersion
- Improved Workability
- Reduced Shrinkage and Cracking
- Enhanced Durability
LANDU ACCURATE RDP powder is a key additive in repair mortar to enhance bonding strength and durability. It can improve the adhesive strength between the mortar and the substrate, ensuring the repaired material firmly adheres to the surface of the wall without peeling. It also endows the mortar with exceptional flexibility, making it adapt to small deformations without cracking, therefore extending the service life of grouting mortar.
- Enhanced Adhesion
- Improved Waterproof
- Intensified Workability
RDP can improve the workability and water retention of mortar, making the mixing and application of mortar smoother and enhancing construction efficiency.
- Extended Service Life
Enhancing the various properties of mortar makes the repair material more stable and reliable during long-term use, effectively extending the service life.
