Concrete Furniture Care & Maintenance Guide
Preserving Your GFRC (Glass Fibre Reinforced Concrete)
Gumi Works pieces are engineered for commercial-grade durability, yet their hand-cast concrete nature requires mindful care. Because our polished concrete is a "living" material, it develops a unique character over time. This guide helps you maintain the tactile finish and structural integrity of your bespoke concrete furniture.
The First 14 Days: Curing the Concrete Sealer
Your piece arrives with a professional concrete sealer that continues to harden for two weeks after installation.
During this critical curing phase:
- Avoid heavy use or leaving standing liquids on the concrete surface.
- Protect the surface from other trades or tools if renovations are ongoing.
Daily Rituals: Cleaning Concrete Surfaces
- Routine Cleaning: Use a damp microfibre cloth with pH-neutral soap. Avoid abrasive scrubbers or harsh chemical cleaners which can strip the protective coating.
- Heat & Scratches: Always use trivets for hot pans and chopping boards for food prep. Do not drag sharp or heavy objects across the concrete tabletop.
- Stain Management: While Gumi Works products are stain-resistant, wipe up acidic spills (lemon, wine, oils) promptly to prevent etching the sealer.
Long-term Concrete Maintenance
To maintain the deep, tactile lustre of your cast concrete, we recommend applying a food-grade wax (beeswax or carnauba) every few months. This creates a “sacrificial layer” that protects the concrete finish from daily wear and tear.
Note: A comprehensive Concrete Care & Maintenance manual is provided with every Gumi Works commission to ensure your artisan concrete lasts for decades.
