Acrylic Waterproofing Coating Formulation: Ingredients, Process & Plant Setup
Elastomeric acrylic waterproofing coatings form a flexible, crack-bridging film on roofs and walls. Performance comes from a low-Tg acrylic binder at high binder-to-filler ratio, with TiO2 for reflectivity.
Acrylic Waterproofing Coating ingredients and their role
| Ingredient | Function |
|---|---|
| Elastomeric acrylic / styrene-acrylic emulsion | Flexible film, elongation and crack bridging |
| Titanium dioxide (rutile) | Opacity and solar reflectance |
| Calcium carbonate / talc | Extenders |
| Dispersant and wetting agent | Pigment dispersion |
| Defoamer | Air release |
| HEC / associative thickener | Viscosity and sag control |
| Coalescent, ammonia, biocide, fibres (optional) | Film formation, pH, preservation, reinforcement |

Get the complete Acrylic Waterproofing Coating formulaManufacturing process
- Charge water, dispersant, wetting agent and defoamer; start the disperser.
- Add TiO2 and extenders and grind to the required fineness.
- Let down at lower speed with the acrylic emulsion.
- Add coalescent, thickener, pH adjuster and biocide.
- Check viscosity and fineness; fill in buckets.
Machinery required
- High-speed disperser (HSD)
- Let-down tank with slow stirrer
- Hegman gauge, viscometer
- Bucket filling
Quality control tests
- Elongation at break and tensile strength
- Crack bridging
- Water absorption / ponding
- Solar reflectance
- Viscosity and solids
Frequently asked questions
Why does waterproofing coating crack?
Binder Tg too high, too much filler for the binder, or film applied too thin.
Is fibre necessary in roof coating?
Optional; fibres add reinforcement for crack-prone substrates.
