Eco Grout | Water-Based Acrylic Binder for Concrete Pinhole Filling

Achieve a flawless, mirror-like finish on your polished concrete. Eco Grout is a specialised liquid pore filler designed to plug the tiny pinholes, fine cracks, and air pockets that naturally emerge during the concrete grinding and polishing process.
 
By mixing this advanced liquid with the concrete dust generated from your floor, it creates a seamless, perfectly colour-matched paste that makes surface imperfections completely disappear.
 
Why Eco Grout is a Game Changer
Fills Tiny Pinholes & Air Pockets: During grinding, tiny air pockets often open up and ruin a smooth look. Eco Grout acts as a high-performance "pore filler," blending with cement dust to cleanly pack those holes for a perfectly smooth, professional surface.
Zero Shrinkage (Won’t Pop Out): Many cheap fillers shrink as they dry, causing them to pull away from the edges and eventually "pop out" of the holes down the track. Our advanced formula stays completely stable, ensuring a permanent repair that won't recede or fall out.
Tenacious Acrylic Bond: Formulated with a unique acrylic resin that locks onto both the bare concrete substrate and the loose cement dust. This deep structural bond easily withstands heavy mechanical pressure and won't lift or tear during your subsequent diamond polishing stages.
Toughens the Surface & Stops Dust: It modifies and hardens the concrete surface, drastically reducing annoying concrete dusting and chalking. This results in a cleaner environment and extends the overall life and resilience of your finished floor.
Fast-Drying & Easy to Use: Engineered to dry quickly so you can progress smoothly through your polishing stages without long, frustrating delays.
Water-Based & Safe: Eco Grout is water-based and virtually odourless, making it significantly safer and more pleasant to work with in enclosed indoor spaces compared to harsh, smelly chemical fillers.
 
How to Use It (The 2-Step Application)
The application process is incredibly straightforward and adapts easily to your project workflow.
Always start with The Mix:
Blend 1 part Eco Grout with 1 part clean water. Then choose your method:
The Trowel Method: Mix your diluted Eco Grout liquid with clean concrete dust in a bucket to create a smooth paste, then skim it across the floor using a hand trowel to pack the holes.
The Grind-In Method: Spray the diluted Eco Grout liquid directly onto the concrete floor ahead of your polishing machine, and let your diamond pads grind the fresh concrete dust right into the wet holes automatically.
The Clean-up: Once completely dry, simply run your next concrete grinding or polishing stage right over the top to remove any excess haze and reveal your perfectly repaired, glass-like surface.
 
Performance at a Glance
Coverage Guide: Highly economical! 1 Litre of the concentrated mix covers approximately 5 to 7 square metres. Check out our coverage calculator down below.
Appearance: Looks like a milky white liquid in the bottle, but dries completely clear as it bonds with your concrete dust.
Application Temperature: For perfect results, avoid applying Eco Grout if the ambient or floor temperature is over 30°C.
