Winter is coming…for your stone
For a certain number of days – some say a couple, others say 12 – winter means fun, festivities, family and figgy pudding. Other activities might include roasting chestnuts on an open fire, decking halls with boughs of holly, hanging stockings and unwrapping gifts excitedly.
The rest of the days of winter, however, mean something else: Freezing temperatures, snow, frost and all manner of other weather phenomena. And while we all know how much fun it is to build a snowman or make a snow angel, the fact is these different atmospheric effects make surface protection for stone in winter essential.
Snow doubt about it – winter can damage your stone
Winter is primetime for damage to natural stone. Snow and frost are nothing more than frozen water, and as dedicated readers of Surfacepedia know, water is to stone as the sun is to Frosty the Snowman. The porosity of natural stone means water can easily seep in through its surface, causing a number of problems.
This is especially so during winter, for two main reasons:
1. With snow pummeling your natural stone outside and heaping on in layer after layer, there's a great deal of potential for moisture to enter your stone surfaces. This can happen to your driveway, for example, or on your marble patio.
2. With lower temperatures, the chance for freeze-thaw spalling – the process whereby water inside stone expands upon freezing, pushing the stone articles apart – increases exponentially.
In fact, according to a 2012 report from CNN, blizzards in Italy at the time did extensive damage to historic stone structures like the Colosseum and the walled town of Urbino, leading to parts of the monuments crumbling.
