How to Make Rustic Texture Paint: Complete 1 KG Formula & Manufacturing Process
Rustic Texture Paint is a decorative wall coating designed to create a natural, textured and attractive finish on interior and exterior surfaces. It can be used to create fine, medium or heavy rustic effects depending on the particle size of the quartz or silica sand used in the formulation.
For small manufacturers, contractors and entrepreneurs, Rustic Texture Paint can be an interesting value-added coating product because the formulation can be adjusted according to the desired texture, colour, finish and application method.
This guide explains a practical 1 KG starting formulation, the function of each raw material, manufacturing procedure, application method, texture options, quality-control parameters and common problems.
What is Rustic Texture Paint?
Rustic Texture Paint is a thick, water-based decorative coating containing an acrylic binder, mineral fillers and graded texture particles.
Unlike ordinary smooth wall paint, Rustic Texture Paint is designed to leave a visible textured pattern after application.
The final appearance depends mainly on:
- Type of acrylic emulsion
- Filler selection
- Quartz/silica sand particle size
- Product viscosity
- Application tool
- Application technique
- Pigment colour
- Drying conditions
It can be applied using a texture roller, brush, trowel or other suitable decorative application tools.

- Texture
- Cost control
- Smooth consistency of the base
The particle size of the calcium carbonate can influence the final finish.
3. Dolomite Powder – 150 g
Dolomite Powder adds mineral body and contributes to the texture and overall structure of the coating.
It can also help modify the surface appearance and working consistency.
4. Quartz Sand / Silica Sand – 250 g
Quartz Sand is one of the most important materials for producing the rustic texture.
The particle size determines the final texture.
Fine Rustic
Approximately 0.2–0.4 mm
Medium Rustic
Approximately 0.3–0.8 mm
Heavy Rustic
Approximately 0.8–1.5 mm
The sand should be clean, dry and properly graded.
5. Titanium Dioxide – 20 g
Titanium Dioxide provides whiteness and opacity.
It is particularly useful when producing light-coloured or white Rustic Texture Paint.
For darker shades, the TiO₂ level can be adjusted depending on the required colour and hiding power.
6. Talc Powder – 40 g
Talc helps improve the body, smoothness and workability of the coating.
It can also influence the final surface feel and application properties.
7. HEC Thickener – 3 g
HEC is used to control viscosity and improve the consistency of the water-based system.
It should be properly hydrated before the main powder dispersion is completed.
8. Dispersing Agent – 3 g
The Dispersing Agent helps distribute mineral powders more uniformly throughout the formulation.
Proper dispersion reduces the possibility of powder agglomeration.
9. Wetting Agent – 2 g
The Wetting Agent helps improve the wetting of mineral powders and other solid ingredients.
10. Defoamer – 2 g
Defoamer helps control unwanted foam during manufacturing and mixing.
Excessive foam can create problems during filling and application.
11. Texanol – 5 g
Texanol is used as a coalescent in water-based coating systems.
It can help improve film formation and the final coating performance, depending on the acrylic emulsion used.
12. Propylene Glycol – 10 g
Propylene Glycol acts as a humectant/co-solvent and can assist with formulation stability and application properties.
13. Preservative – 1 g
The Preservative helps protect the water-based product from microbial spoilage during storage.
The actual dosage should always follow the supplier’s recommended dosage for the specific preservative.
14. Acrylic Thickener – 4 g
Acrylic Thickener provides additional viscosity control and helps achieve the heavy consistency required for texture coatings.
The actual quantity may need adjustment according to the selected acrylic thickener.
15. Water – 30 g
Water is used as the main processing medium and for viscosity adjustment.
The actual water requirement can vary depending on the solids content and viscosity of the raw materials.
Manufacturing Process
Step 1 – Prepare the Thickener Solution
Take approximately 20–25 g of the available water in a clean mixing vessel.
Slowly sprinkle HEC Thickener into the water while mixing.
Allow it to hydrate properly for approximately 10–15 minutes.
Avoid adding the entire HEC quantity at once because it can form lumps.
Step 2 – Add Dispersing and Wetting Ingredients
Add:
- Dispersing Agent
- Wetting Agent
- Defoamer
Mix properly until the ingredients are uniformly distributed.
Step 3 – Add Mineral Powders
Start adding the following materials gradually:
- Calcium Carbonate
- Dolomite Powder
- Talc Powder
- Titanium Dioxide
Add the powders slowly while mixing.
High-speed mixing can be used at this stage to develop a smooth and uniform mineral slurry.
Avoid adding large quantities of powder at one time.
Step 4 – Add Acrylic Emulsion
Once the mineral slurry is reasonably uniform, reduce the mixing speed.
Add Acrylic Emulsion – 180 g slowly.
Continue mixing until the binder is uniformly incorporated.
Avoid unnecessarily high shear after adding the emulsion.
Step 5 – Add Liquid Additives
Add:
- Propylene Glycol – 10 g
- Texanol – 5 g
Mix thoroughly.
Step 6 – Add Acrylic Thickener and Preservative
Take the remaining water and mix the Acrylic Thickener and Preservative into it according to their compatibility and supplier instructions.
Add this solution slowly to the main batch.
Continue mixing until the viscosity becomes uniform.
Step 7 – Add Quartz/Silica Sand
This is an important stage.
Add Quartz Sand / Silica Sand – 250 g slowly.
Use low-speed mixing.
Do not use excessive high-speed mixing at this stage because aggressive mixing can damage or unnecessarily break the texture particles.
The objective is to distribute the sand uniformly without destroying its particle structure.
Step 8 – Viscosity Adjustment
Check the consistency of the finished product.
If the product is too thick, make small adjustments using water.
If additional body is required, the thickener system can be adjusted carefully.
Avoid making large adjustments at once.
Step 9 – Resting and Final Mixing
Allow the finished batch to stand for approximately 12–24 hours where practical.
Before packing, mix slowly again to achieve uniformity.
Check the finished product for:
- Texture
- Viscosity
- Colour
- Smoothness
- Sand distribution
- Foam
- Application behaviour
How to Apply Rustic Texture Paint
The surface should be clean, dry and free from loose dust, grease, oil and weak paint.
Basic Application Procedure
- Prepare the wall surface properly.
- Apply a suitable primer.
- Allow the primer to dry.
- Apply Rustic Texture Paint using a suitable roller, brush or trowel.
- Create the desired pattern while the coating is workable.
- Allow the coating to dry properly.
- Apply additional decorative or protective coating if required by the selected system.
The exact application thickness depends on the desired texture and particle size.
How to Make Different Rustic Finishes
Fine Rustic Finish
Use a smaller particle size, approximately 0.2–0.4 mm.
This produces a relatively fine decorative texture.
Medium Rustic Finish
Use approximately 0.3–0.8 mm graded particles.
This provides a more visible rustic effect.
Heavy Rustic Finish
Use approximately 0.8–1.5 mm particles.
This creates a stronger, more pronounced textured appearance.
How to Make Coloured Rustic Texture Paint
The base formulation can be coloured using a compatible water-based universal pigment paste.
Common colour options include:
