What are the effects of acid rain on pine outdoor armchairs?
Acid rain can significantly harm pine outdoor armchairs, causing both visible and structural damage over time. The acidic components in rainwater, such as sulfur dioxide and nitrogen oxides, break down the lignin and cellulose in pine wood, weakening its fibers. This leads to discoloration, surface erosion, and increased susceptibility to cracking or warping.
Prolonged exposure accelerates decay, shortening the lifespan of the furniture. To mitigate damage, apply a protective sealant or varnish, clean the wood regularly, and consider covering or storing chairs during heavy acid rain periods. Choosing treated pine or alternative weather-resistant materials can also help preserve outdoor furniture in affected areas.
