Render only onto Board

A render only application system onto timber or metal frame structures that already achieve their thermal performance from within the frame.


The use of a JUB approved Render carrier board is essential along with the versatile JLM 20 basecoat, JUB Primer and a choice of JUB render finishes.

The boards are fixed back to the frame of the structure in accordance with the manufacturer’s instructions before the joints are filled with a JUB acrylic mastic to prevent excessive stress movement. The JLM 20 basecoat is then applied directly to the board to a 5mm thickness with a layer of JUB reinforcing mesh trowelled into the whole surface area and then allowed to dry before applying the JUB primer.

A wide range of JUB finishes can then be used with the render onto board system.

Please contact the JUB technical department for more information and a list of approved carrier boards.
