Silic8 MPL2 Primer

Silic8 MPL2 is a mineral based plaster primer which is designed to control many high suction backgrounds whilst still re- maining vapour open. MPL2 can also be used to consolidate problematic surfaces and substrates. The primer’s fine gritted surface provides a key for a new suitable plaster to bond to but also allows for thin skim coats.  MPL2 is the only plaster primer on the market to be 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 non-hazardous.  Our MPL2 plaster primer is available in 7kg or 16kg UN certified containers.

Some typical substrate types: Masonry backgrounds, magnesium silicate boards, 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.

Preparation

Substrates must be clean and dry and free from any loose material prior to application.

Test a small area for suitability with your specific materials before use*.

Do not use on contaminated surfaces, extreme environments or in any unusual circumstances.  Do not store or use in extremes of temperature (<5C or above 30C).

Protect surrounding surfaces, particularly glass.

Store in airtight containers and used within 12 months.

 Do not store, or use in temperatures <5C or above 30C.

Application

 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 left).

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.

Silic8 vapour open liquid primer penetrating solution (PS1 or PS2) is recommended prior to application on problematic or highly adsorbent surfaces.

Allow to cure for 2-24 hours depending on temperature and applied thickness.

 Appropriate vapour open plasters can be applied at any point after 24 hours and MPL2 has fully cured.

 Ensure that the plaster is appropriate to the task.

Coverage:

On an even surface 500grams of MPL2 will cover approximately 1m²

Aftercare:

Allow to dry completely before further application, plaster coverings or decoration.

Wash splashes, tools and brushes with water.

Dispose of all surplus material in accordance with your local regulations (EWC 06 02 99).

Cleaned tins are 100% reusable and recyclable.

 

If splashed on the skin wash off immediately with water. Wear the appropriate Personal Protective Equip- ment; Refer to the Safety Data Sheet before use
