Outdoor epoxy flooring and exterior floor paint
Standard bisphenol-A epoxy is an indoor resin: outdoor UV light yellows and chalks it within months, and trapped ground moisture can blister it in frost.
Free, no obligation. One local installer prices it, not five.
Sunlight, rain and frost
- UV yellowing and chalking. Daylight breaks down aromatic epoxy polymers, turning clear or grey epoxy a patchy amber yellow within weeks.
- Trapped ground moisture. Outdoor slabs sit on wet soil without a damp-proof membrane. An impermeable indoor epoxy coat traps rising vapour until sun or frost blisters it.
- Wet slip risk. Smooth gloss epoxy becomes slick in Irish rain unless aggregate grit is broadcast into the surface.
The exterior resin systems that last
| Outdoor system | Where it goes | Why it works outdoors |
|---|---|---|
| Aliphatic polyaspartic or PU flake/quartz | Balconies, front steps, carports, threshold aprons | 100% UV-stable binder with broadcast quartz grit for wet grip |
| Two-pack aliphatic PU exterior paint | Concrete yards, loading bays, external stairs | UV-stable pigment and micro-porous weather resistance |
| Permeable resin-bound aggregate (15–18 mm) | Driveways, patios, garden paths | Aliphatic PU resin mixed with washed stone so rainwater drains straight through |

Questions people ask
Can I use leftover indoor garage epoxy outside on steps or a patio?
No. It will yellow in daylight, turn slippery in the rain and likely peel after the first winter frost.
What is the best anti-slip finish for outdoor concrete steps?
A damp-tolerant primer followed by an aliphatic polyaspartic or polyurethane coat broadcasted with kiln-dried quartz sand to achieve a wet Pendulum Test Value (PTV) above 36.
