Is elastomeric recommended for T 111 siding that has high sun exposure? I heard it was only for concrete or stucco, not wood siding.
Possibly the best exterior finish is elastomeric paint. This coating is so durable it can outperform even the best 100% exterior acrylic paint by 2 to 1. Elastomeric paint forms a durable, tough film that provides a waterproof coating to almost any structure. This paint is resistant to sunlight, heat, cold and wind drove rain. I was also confused just like you but as I belong to Florida so I took the help of Florida Contractors to make the project easy and reliable.
