Why does water damage your woodwork?
Even on a thin shutter slat, water always finds a way in… but it can't get back out.
Water seeps in
Through microcracks, the wood's pores or areas where the paint is damaged, water penetrates the wood.
Water spreads by capillary action
It travels through the wood fibres, like through a sponge.
Moisture stays trapped
As it tries to get back out, the water meets the intact paint that acts as a barrier. It can no longer evaporate.
The wood deteriorates
Trapped moisture causes swelling, cracking, then flaking of the paint. The wood eventually weakens and deteriorates.
Water gets in easily but can't get back out. Over time, the wood deteriorates and the paint flakes.
Flaking, blisters, cracks and bare patches: these are the signs that water has got in and stayed trapped.
