Product Overview
MgO Plasterbond is a mineral based plaster primer which is designed to control high suction backgrounds on Magnesium
Oxide (MgO) boards whilst still remaining vapour open. The primer’s fine gritted surface provides a key for a new suitable
plaster to bond to.
MgO Plasterbond is independently tested by audited facilities Sheffield Hallam University and PRA coatings, for vapour
diffusion to reassure you that water vapour is not trapped in the fabric of your building. No VOC, no odour, water-based and
certified as vapour permeable.
Our natural mineral and water-glass primer free from any other co-binders such as solvents, gypsum and cement and is nonhazardous. MgO Plasterbond plaster primer is available in 17kg UN certified containers and is been specially formulated for
use with magnesium oxide faced Spacetherm Wall Liner and Spacetherm Multi boards.
