Horizontal vs. vertical Horizontal and vertical surfaces are both impacted by Mother Nature. In general, however, horizontal surfaces require a greater degree of maintenance and preventive treatment. Deck surfaces also have to deal with the impact of heavy foot traffic.

Depending on where you live, here are some of the ways nature can impact your wood:

• Ultraviolet light. Over time UV light can cause fading, especially on horizontal surfaces, which are more exposed than vertical surfaces. For long-lasting protection we suggest using one of Cabot's specially formulated UV-resistant stains.
• Moisture. Raindrops, dew and melting ice roll off siding and fences quickly, so those surfaces aren't impacted as strongly as deck surfaces. Puddles on horizontal surfaces can seep into unprotected wood, where it can nourish mold and mildew.
• Temperature shifts. In cold climates, freezing puddles of water can crack wood. In warm areas, hot temperatures can dry wood, causing fading and cracking. On days of extreme temperature swings, wood expands and contracts to a greater degree, making it susceptible to cracking.
