EPIREZ Epoxy Grout Aggregate Extender (QA30) 16L
Quartzite aggregate extender for deeper epoxy grout pours and hot weather applications.
EPIREZ® Epoxy Grout Aggregate Extender (QA30) is a carefully selected blend of inert quartzite granules designed specifically for use with EPIREZ epoxy grout products. With a graded particle size of approximately 0.6–1.4 mm, QA30 can be added to EPIREZ High Performance Epoxy Grout (280S) to increase the grout volume and assist with deeper pour applications.
QA30 is particularly useful for deep epoxy grout pours and hot weather grouting, helping extend the High Performance Epoxy Grout for suitable applications. It is designed to be incorporated after the hardener has been added and mixed into the epoxy grout until fully dispersed.
Key Features

- Deep epoxy grout pours
- Machinery base grouting
- Heavy-duty equipment grouting
- Structural epoxy grouting
- Hot weather grouting applications
- Applications requiring extended epoxy grout volume
Compatibility
QA30 is specifically designed as an aggregate extender for EPIREZ epoxy grout products.

Application Instructions
Add QA30 slowly to the mixed EPIREZ High Performance Epoxy Grout (280S) after the hardener has been incorporated. Continue mixing until the aggregate is fully incorporated throughout the grout.
Do not aerate the mixture. Pour the extended epoxy grout slowly into the prepared void from one side only to minimise air entrapment. Equipment should not be installed or placed into service until the epoxy grout has achieved full cure.
Ideal for: epoxy grout extension, deep pour epoxy grout, machinery grouting, structural grouting, heavy-duty grouting and hot weather epoxy grout applications.
Always refer to the current manufacturer's technical and safety documentation for specific mixing quantities, application requirements and project recommendations.
Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
