18. Architectural Concrete Coaster Set with Holder
Introduction
Protect your wooden coffee tables in style. An architectural concrete coaster set complete with a matching minimalist storage holder brings industrial sophistication to your daily beverage routine.
What This Idea Means
A stack of sleek, hexagonal or circular concrete drink coasters housed neatly inside a precision-cast matching concrete storage caddy.
How to Make It
- Coaster Molds: Use shallow silicone tile molds to cast uniform circular or hexagonal coasters.
- Caddy Form: Build a slightly larger square or matching geometric box mold with a center interior spacer to form the holder sleeve.
- Pouring: Cast all pieces simultaneously using a dense, water-resistant concrete mix.
- Protection: Once cured and sealed, stick small circular cork pads to the bottom of each coaster to ensure zero surface scratching on furniture.
Tips and Variations
- Water-Repellent Nano Coating: Treat the top surface of the coasters with a hydrophobic concrete sealer so water beads up instantly without leaving rings.
- Geometric Etched Patterns: Press rubber stamps into the wet surface of the coasters to imprint subtle geometric mandalas or grid patterns.
