What is GFRC Concrete?
Our GFRC, or Glass Fibre Reinforced Concrete, is not concrete as you know it.
It can be made very thin (as thin as 20mm) and flows like liquid stone. When poured into a mould it flows into every corner with no need for special tools with the result being an extremely smooth nigh on perfect finish.
There are no large aggregates (stones) in this type of concrete but instead glass fibres which make it much stronger and more suitable for worktops and decorative concrete.

How is GFRC different from standard concrete?
Traditional concrete relies on gravel and bulk for strength. GFRC uses fibres for reinforcement—so it can be cast as thin as 20 mm and still stay rock-solid. That means less weight, finer detail, and fewer cracks.
What can I make with GFRC?
Our GFRC system is built for:
Kitchen and bathroom worktops
Integrated sinks and basins
Wall panels and decorative furniture
Outdoor bar tops and garden kitchens
If you can mould it, you can make it.

Is it DIY-friendly?
Yes. That’s why we built the system—everything you need is available as kits. With our guides and calculator, first-timers achieve pro results.

How much does one bag cover?
Each 21.67 kg pack covers roughly 0.6 m² at 18 mm thickness. Use our online calculator to plan your project and get the exact quantities you’ll need.

What thickness should I pour?
For worktops, 18–20 mm is ideal. Thicker around cutouts or overhangs—reinforce with our fibreglass bars in those areas.

Do I need special tools?
No heavy machinery. You’ll need a mixing paddle, trowels, and a few other bits and pieces like an orbital sander, roller and frame.

Do I need to vibrate the mix?
Not really. The mix is self-compacting and flows into detail like liquid stone. A gentle tap helps release trapped air, but over-vibration can disturb the fibres.

How long does it take to cure?
Allow 18 hours before demoulding and handling. It reaches twice the strength of normal concrete in just 7 days.

Can GFRC crack?
It’s extremely rare. The fibre reinforcement prevents structural cracks, even in thin sections. Proper curing and reinforcement around cutouts eliminate most risk.

How do I protect the surface?
Always seal. Our Concrete Lab Sealer resists stains, water, and oils. For a soft sheen use our satin sealer, finish with Concrete Wax. Re-seal periodically depending on use.

Is it waterproof?
Once sealed, yes. GFRC surfaces are water- and stain-resistant, suitable for kitchens, bathrooms, and even outdoor use.

Can I colour it?
Absolutely. Choose from Off White, Light Grey, Mid Grey, Dark Grey, or Pink, or add pigment packs for custom shades.

Can I use it outdoors?
Yes—just ensure you use Concrete Lab Sealer and Wax for UV and weather protection. Re-seal annually for longevity.

How do I clean it?
Mild soap and water only. Avoid harsh chemicals or acidic cleaners. Re-apply wax occasionally to refresh the finish.

Can I get a colour sample before ordering?
Yes. Our GFRC Sample Packs use the exact same formula as our full kits so you can test real colour, texture, and finish before committing.
