Sag resistance
Helps mortar stay in place on vertical surfaces—supports anti-slip tile adhesive performance.

Rheology Modifier for Mortars
Rheology modifier used to improve sag resistance, cohesion, and workability in mortars and dry-mix systems. Grade selection depends on your binder, fillers, and target application feel.
✓ Anti-sag & slip control
✓ Thixotropy & cohesion tuning
✓ Powder supply: bags / supersacks
✓ SDS / COA / TDS on request
Packaging: 25 kg bags / big bags (lane-dependent)
Documentation: SDS / COA / TDS on request
Lead time depends on grade, volume & origin
Workability & feel
Improves trowelability, cohesion, and consistency—reduces “watering out” or harsh feel.
Process stability
Supports more consistent application across temperature and sand variability (formulation dependent).
Best results come from lab trials that tune water demand, open time, slip/sag targets, and compatibility with polymers and defoamers.
What it is
Rheology modifiers are specialty additives that adjust the flow profile of mortars—often increasing thixotropy and cohesion so the mix resists sagging while maintaining workable application feel. In many dry-mix mortar systems, rheology and water retention are tuned together to meet practical site performance requirements.
Where it adds value
- Tile adhesives: improved slip resistance and stable bed thickness
- Renders & plasters: better cohesion and reduced slumping on walls
- EIFS/basecoats: improved workability and placement stability
- Repair mortars: better trowelability and reduced sag in patches
- Gypsum systems: tuning flow/feel and improving application behavior
Procurement note
We quote against your application type, binder system, and target sag/workability—so you get a grade that performs in trials and scales in production.
Final performance depends on the full formulation (cement/gypsum, fillers, sand grading, RDP/polymer, defoamer, retarders/accelerators, and water demand).
Selection guide
Different mortar systems need different rheology tools—tell us your target and we’ll align a practical grade.
Thixotropy tuning
Builds “stand-up” behavior for vertical/overhead application while keeping a workable flow under shear.
Typical ask: anti-sag renders / repair mortars
Anti-slip tile adhesives
Supports slip resistance and stable ridge profile—helps control tile movement during installation.
Typical ask: wall tile adhesives (improved slip)
Workability & cohesion
Improves application feel, reduces segregation, and supports consistent finish (formulation dependent).
Typical ask: smooth trowelability, reduced “harshness”
Compatibility checklist (practical)
Fast checks that prevent reformulation surprises.
Binder chemistry
Cement/gypsum/lime type, alkalinity, and hydration profile affect rheology response.
Polymer & defoamer
RDP choice and defoamer level can change air content and workability—test together.
Fillers & sand grading
Particle shape and grading drive water demand and cohesion—affects required dosage.
Applications
Typical usage patterns. Tell us your process and constraints and we’ll align the right specification.
- Tile adhesives (anti-slip / anti-sag performance)
- Cement renders, plasters, and repair mortars (sag control)
- EIFS/basecoats (cohesion and application feel)
- Gypsum plasters and patching systems (flow/feel tuning)
- Dry-mix optimization for stable production and site repeatability
Dosage guidance (practical starting points)
Typical range
Often ~0.1%–0.6% of total dry mix (grade and system dependent). Optimize via lab trials.
What to optimize
Sag/slip, open time, water demand, trowelability, air content, and finish quality.
How to validate
Trial panels: vertical sag, slip resistance, consistency, adhesion and curing performance as required.
Tip: Many mortar issues are system-level—optimize rheology together with polymer, defoamer, and water retention to avoid trade-offs.
Typical specifications & supply formats
Values depend on grade and customer requirements. Confirm details on quotation (TDS/COA).

FAQ
Quick answers for procurement and formulation planning.
Does a rheology modifier replace cellulose ether or polymer?
Not usually. Many formulations use multiple tools (rheology modifier + water retention + polymer) to balance sag resistance, open time, adhesion, and workability.
Will it change water demand?
It can. Some grades increase cohesion at similar water levels; others may shift water demand. Trials determine the best balance for strength and finish.
How do I choose the right grade?
Tell us application type, binder system, target sag/slip and workability window, and your polymer/defoamer package. We’ll propose a suitable grade and starting dosage for trials.
What packaging is available?
Commonly 25 kg bags; big-bags may be available depending on lane and destination. Share your unloading/handling setup and preferred packaging.
Do you provide supporting documents?
Yes—SDS, TDS, and COA can be provided on request as part of the procurement documentation pack.
Can you support lab trials?
We can advise a practical starting window and what to measure (sag/slip, open time, water demand, air content, adhesion), then tune based on your results and targets.
