Price Not Available In Your Country, Please Contact Us


Primer I.M is an exterior render primer for use in Passive Purple External system. A Waterborne primer, applied on porous and less cohesive substrates, prior to the application of waterborne dispersion coatings. Typically used on older dusty substrates and porous substrates like concrete bricks, calcium silicate stone, renders. Comes in a 10KG liquid container.

  • Description

    Why Choose Primer I.M?

    • Pre-treatment peace of mind

    Used as a post treatment after installation of Passive Purple®, Airtight White® & Passive Purple® External. The use of this wall primer will consolidate and close off difficult porous substrates like concrete bricks, calcium silicate stone and lime renders. The small molecules in it enter deeply into the substrate and once absorbed function to consolidate as well as a primer. You then apply water dispersion coatings over the top.

    • How does it work differently to Lime Prime?

    Has much smaller molecular structure so it’s not to be used on render or porous concrete block because it has no/little effect.

    Used as a pre-treatment before installation of Passive Purple External. It’s microemulsion, a small molecular makeup enters deeply into the substrate so it functions to consolidate as well as a primer.  To be used on dense substrates: concrete, (old) lime, Primer I.M is the choice for old render/old lime, because these surfaces need consolidation before applying a coating on it.

    • Works together with our air & vapour control membranes

    Due to the high vapour permeability of Primer I.M it can accommodate subtle movements (without cracking). It sits on top of substrates and works in perfect unison with our air & vapour control membranes’ high tensile elongation values and is a perfect solution for older buildings that move a lot. 

  • Uses

    Application – Apply Lime Prime by a low pressure or with airless spray equipment with just one layer approximately 100 gr/m2, depending on the porosity of the substrate.

    To be used on:

    • Older/Dusty substrates
    • Porous substrates such as concrete bricks, calcium silicate stone and old lime
  • Data Sheets & Certificates
  • Architects Specification
