Calcium Carbonate Selection for Wall Putty
If you formulate wall putty, select calcium carbonate for application feel, water demand, finish and sanding rather than mesh alone.
Relia's catalogue includes carbonate candidates with different particle descriptions.
- Powder
- Distribution and blend identity
- Mix
- Water demand and workability
- Sanding
- Your accepted panel criteria

A Factory Proposal for Your Application
Relia manufactures ground, precipitated and selected surface-coated calcium carbonate grades in China through its own factories.
We can review your putty filler enquiry with the intended substrate, binder and application thickness. Give us the current powder and the changes you want to investigate. The shortlist should keep particle data and grade identity clear, so your applicator or production trial can compare a specific material change.

Application before Fineness
Textured coatings and construction formulations can need a different particle window from a smooth high-gloss paint. Our 600 mesh and 800 mesh GCC listings sit within a broader 600–3000 mesh range. We start with the surface and application requirement before selecting a grade to evaluate.

Mesh Options for Construction Coatings
| Review area | Listed data and acceptance basis | Use in your selection |
|---|---|---|
| 600 mesh GCC · 6509 | The entry states 96% CaCO3. Confirm the relevant particle distribution and residue for the intended texture. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| 800 mesh GCC · 6508 | Also listed at 96% CaCO3. Compare the actual grading instead of treating purity as the only difference. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| GCC range · 6538 | The 600–3000 mesh catalogue range contains options. The quotation needs to identify the offered option explicitly. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| Applied coating | Define texture, workability, coverage and adhesion requirements with the formulation and substrate. | Keep chemical identity, assay basis and the actual offered grade in the same specification. |
Relevant Grades for Your Shortlist
Use these listed candidates to start a grade-specific discussion with us.
A Putty Panel Comparison
Use a representative substrate and the intended application method. Record workability, visible texture, coverage and the finished properties your coating needs. If a grade changes the water or binder demand, keep that formulation adjustment visible so the comparison remains useful for purchasing.

Finer labels
Are not a complete specification.
Water changes
Can distort the comparison.
Single powder value

Particle Preparation and Surface Condition
Classification sets the distribution entering the putty, including the coarse particles that may influence finish. More fine material can also change wetting and water demand. Retain the complete distribution and the preparation conditions, then compare spread, drying, surface and sanding on panels rather than inferring the result from a larger mesh number.
GCC: dry and wet routes
Relia uses both dry- and wet-grinding routes for GCC. Grinding and classification are connected to the selected powder's particle specification.
PCC: crystal formation
Relia produces PCC through calcination, slaking and carbonation. The precipitation route forms new particles rather than only grinding the starting mineral.
Selected surface-coated grades
Relia applies surface coating to selected carbonate grades. The actual treatment and intended application remain part of the grade discussion.
Defined carbonate checks
Routine batch checks cover whiteness, moisture and purity. Particle size and oil absorption are checked according to the grade or order requirements.
- Distribution
- Retain average size, D50 and D97 as their actual reported measurements.
- Surface
- Connect a treatment declaration with the application and absorption or wetting evidence.
- Identity
- Keep the selected grade and relevant method with the sample comparison.
A Purchase Specification with Purpose
The approved powder and panel reference belong together. We discuss repeat supply against that record and the agreed grading requirements. Changes that affect application or sanding have a clear point of comparison.

Choose the Next Useful Guide
If you make waterborne interior paint, buy calcium carbonate for the paint balance you need: opacity, viscosity, application and film properties.
If you are sourcing calcium carbonate from China, start with the product you make and the powder characteristics it needs.
If a promising sample needs to become a repeat purchase, make the approval record as clear as the trial result.
