Direct Render Boards

Direct Render Boards are used as a substrate for a variety of thin coat polymeric renders, textured finishes and other surface coatings providing a seamless finish in all applications. Render Boards are characterized by high tensile strength that resists bending to prevent cracking and deformity, providing an excellent resistance to impact damage.

Vivalda direct render boards are class ‘O’ fire rating and are not affected by moisture and water penetration. The boards are easy and quick to install. The rough surface of these boards is suitable for direct application of a wide range of finish renders. This ease of application and finishing enables the reduction of on site working schedules, proving to be cost effective.

BluClad

Bluclad is the first breakthrough asbestos-free building board technology classified as Calcium Silicate board. BluClad is a flat Class O building board with outstanding dimensional stability. Bluclad can be used as substrate for a variety of thin coat polymeric renders, textured finishes and other surface coatings. Bluclad can also be used to provide a seamless finish. Bluclad is available in a standard 10mm thickness, it is off white in colour , has a smooth surface on the front and is textured on the reverse. The smooth face is for painting and the textured face is for thin coat polymeric renders.

Recommended Applications

Bluclad can also be used within an insulated render system.

Fixing

BluClad can be installed using either countersunk screws (number 6 - 8) or nails (5mm minimum head diameter).
BluClad should be fixed to support studs at maximum 600mm centres. BluClad can be finished with this thin coat polymeric renders or other surface coating.

Finishing

Where seamless finishes are required, building boards should be installed "stretch bond" fashion, i.e. long edges horizontal and vertical edges staggered.
Note: BluClad must be decorated for external use.

Cutting

BluClad is easy to cut on site with standard woodworking tools.
