The Right Product for the Job Whether you’re building or remodelling, avoid the problems of inferior grade boards. You want your project to be a labour of love, most importantly, you want to know your project will be trouble free for many years to come. Experienced Architects, Interior Designers, General Contractors and Renovation Contractors know the problems associated with inferior-grade backer boards. When in contact with moisture and humidity, lower quality backer boards begin deteriorating, rotting, warping, buckling or blistering. As the problems grow, especially in gypsum-based products, you are stuck with expensive repairs.
