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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eHow does it work differently to Lime Prime?\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHas 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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cb\u003eWorks together with our air \u0026amp; vapour control membranes\u003c\/b\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eDue to the h\u003c\/span\u003e\u003cspan style=\"font-weight: 400;\"\u003eigh vapour permeability of Primer I.M it can accommodate subtle movements (without cracking).
