Cement Board MD Finish System™
An exterior finish system applied over exterior cement board with a secondary weather resistive barrier and moisture drainage.
Dryvit Cement Board MD Finish System is a range of 100% acrylic polymer based anti-crack renders designed to out-perform the shrinkage and cracking characteristics of traditional renders. The range offers a variety of coloured and textured coating options providing various levels of protection when used in the different component combinations. The Cement Board MD Finish System incorporates an exterior grade cement board fixed to vertical batons and is ideal where a cavity system is called for without the need for exterior insulation. Commonly applied over timber or steel framed substrates incorporating an approved sheathing and breather membrane in new build residential and low-rise commercial projects.
