Q • What I can use to seal my fence and keep it sealed for more than a few years?
A • Over the weekend, a customer asked me this question in the store, which sent me on a mission to find the best outdoor sealant on the market. While a lot of products do a great job sealing outdoor fixtures and preventing damage from the elements, many products protect for just a year or two. After a quick walk down the aisle, I found one that fits the bill perfectly. Rainguard® is a new product that claims to seal vertical and horizontal surfaces for up to 10 years. It works on any unpainted porous surface and resists water, dirt and salt.
