Wood protection in Cardiff
Cardiff combines Welsh rainfall with Bristol Channel salt air — one of the wettest and most challenging environments for exterior timber in the UK.
Coastal climate in Cardiff
In coastal climates with high humidity and salt exposure, we recommend SiOO:X Wood Protector in two coats with 24 hours of drying between, followed by one coat of Surface Protector. Plan a maintenance application after 2–3 years for optimal effect.
Cardiff Bay developments and suburban garden projects use Western Red Cedar, Douglas fir and treated softwoods. SiOO:X breathable protection survives the Welsh wet season without trapping moisture or peeling.
