Silic8 MPL1 primer is a mineral based plaster primer that is designed to control many high suction backgrounds whilst still remaining vapour open. Silic8 MPL1 primer can also be used to consolidate problematic surfaces and substrates. The primer’s coarse gritted surface provides a robust key for a new suitable plaster to bond to. Silic8 MPL1 primer is the only plaster primer on the market to be independently tested for vapour diffusion to reassure you that water vapour is not trapped in the fabric of your building.

With no VOCs, no odour, a water-based formula and certified as vapour permeable, Silic8 MPL1 primer is our natural mineral and water-glass primer and is free from any other co-binders or solvents.

Suitable for most substrate types: masonry backgrounds, historic or new plasters (lime, cement or gypsum), stone, wood, and wood type boards, terracotta and some ceramic tiles and paints. An in-house testing facility for bond strength is offered if you have specific requirements.
