The use of this wall primer will consolidate and close off difficult porous substrates like concrete bricks, calcium silicate stone and lime renders (stucco). 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. It’s a microemulsion whose small molecular makeup enters deeply into the substrate, so it functions to consolidate as well as prime. Use Primer I.M on dense substrates such as concrete and old lime — surfaces that need consolidation before a coating goes on.
