Maintenance considerations
Each AMSV manufacturer publishes specific care and maintenance requirements. Most have detailed instructions on sealing, cleaning, efflorescence, power washing, and de-icing chemicals. Installers should read these before proceeding, as they can drastically affect performance and warranty coverage. Sealing is not recommended for AMSV, as it can lead to problems such as water entrapment.
Commonly used to maintain walkways, rock salt and other de-icing chemicals are corrosive to all concrete and, over time, will break down any AMSV in contact with the applciation. (For more, read “Don’t Damage Your Natural Stone Walkways with Rock Salt” at www.mygreenimpressions.com/blog/dont-damage-your-natural-stone-walkways-with-rock-salt.) They also degrade mortar and can cause discoloration. Special care must be taken to ensure de-icing chemicals are not used so generously they contact the AMSV. Immediate repairs should be made to any degrading mortar or grout.
Harsh cleaning, whether with chemicals or power washing, must also be properly managed. Gently cleaning stones with a soft brush using liquid detergent and water should suffice. Employing bleach or other harmful chemicals should be avoided for the protection of the stone product. Manufacturer instructions should be supplied to ensure proper maintenance techniques are followed to prevent avoidable damage.
Conclusion
When it comes to manufactured stone products, several options are available. From contemporary styles to traditional façades, there is a wide variety of high-performance AMSV products. With a number of available textures and colors, AMSV creates stylish, unique siding options without the cost of natural stone. It is also a dependable option for durable exteriors in virtually any climate, making it ideal for new construction or retrofits.
Observing proper techniques for cold-weather installation helps enhance the durability and the longevity of AMSV throughout the entirety of the year, protecting the system no matter the season. Taking proper steps to ensure the siding will dry quickly and the installation is free of voids is the best way to plan for even the harshest winter weather.
