Dry-Mix Mortar Additives
Additives for dry-mix mortar, selected to suit your application, raw materials and performance targets. We support product selection and basic formulation discussions.
- Main Products: HPMC, RDP, PCE powder, polypropylene fibers and PVA
- Applications: Plastering mortar, tile adhesive, wall putty and related mortar products
- Support: Grade selection and trial-based formulation adjustment
Key Features
Water Retention & Workability
Selected HPMC grades help retain water and adjust mortar consistency for smoother application.
Adhesion & Flexibility
Suitable RDP grades help improve bonding and flexibility in tile adhesives, repair mortars and related products.
Water Reduction & Flow
PCE powder helps reduce water demand and improve flow in self-leveling, grouting and repair mortar formulations.
Early Crack Control
Polypropylene fibers help reduce plastic shrinkage cracking through dispersed reinforcement within the mortar.
Main Additives & Functions
HPMC — Hydroxypropyl Methylcellulose
A cellulose ether used for water retention and consistency control. Suitable grades support workability in plastering mortars, tile adhesives, wall putty and gypsum-based products.

RDP — Redispersible Polymer Powder
A polymer powder that redisperses in water and forms a film as the mortar dries. Suitable grades support adhesion and flexibility in tile adhesives, insulation mortars, repair mortars and wall putty.

PCE — Polycarboxylate Superplasticizer Powder
A powder additive used to reduce water demand and improve flow. Typical applications include self-leveling mortars, grouts and repair mortars. Dosage is selected through compatibility and performance trials.

PP Fibers — Polypropylene Fibers
Short fibers that disperse within the mortar to help control early plastic shrinkage cracking. Fiber length and dosage are selected according to the mortar type and mixing requirements.

PVA — Polyvinyl Alcohol
Selected PVA grades provide film-forming and binding support in wall putty and related dry-mix products. Grade selection and dosage should be matched to the formulation and verified through trials.

Basic Formulation Support
We discuss additive selection and basic formulation adjustments based on your target product, local raw materials and performance requirements.
- Define the Application: Identify the mortar type, application method and performance targets.
- Review Raw Materials: Consider the cement or gypsum, sand, fillers and existing additives.
- Select Suitable Grades: Match additive functions and grades to the formulation requirements.
- Review Trial Results: Adjust the formulation using feedback on workability, flow, adhesion and other relevant properties.
Final formulations and dosages should be validated through testing with local raw materials.
