Silic8 MPL2 (FP1) Fine particle Primer

Silic8 MPL2 is a mineral based plaster primer which is designed to control many high suction backgrounds whilst still remaining vapour open. MPL2 is a flexible Vapour Open Fine Particle Mineral Primer, similar to our MPL1, but with a finer grit. Use for stabilising or consolidating surfaces prior to plastering, priming or repair. MPL2 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.

Some typical substrate types: 

Masonry backgrounds, magnesium silicate boards, historic or new plasters (lime, cement or gypsum), wood, and wood type boards, terracotta and some ceramic tiles and paints

Coverage: 

On an even surface 600grams of MPL2 will cover approximately 1m² (7kg  will cover approximately 12m ²). Allow more for uneven surfaces.

Use:

Stir well before use. Apply with a broad brush using short strokes and ensuring that the grit is evenly spread across the surface (see typical spread pattern below). The surface to be primed must be sound and dry. Where the surface is powdery or friable, work the primer in to the affected areas with a brush and test for bond strength after 24 hours.

Ensure that surfaces not to be primed are protected, particularly glass. Wash splashes, tools and brushes with water. Do not store or use in extremes of temperatures. The primer can be plastered after 24 hours. Ensure that the plaster is appropriate to the task
