Our Dry Lime Blebs are added inclusions to match historic mortars. Look at your old mortar, if you see “cottage cheese” like pieces, that’s a lime bleb! Our machines today “knock-up” mortar so this no longer occurs. These are a nice additive to match your historic mortar.
Add Dry Lime Blebs to Lime Putty Mortar right before using the mortar. Do not over mix when adding them to a mechanical mixer as the abrasive action of the sand will break up the lime blebs.
We recommend folding the lime blebs into the lime mortar using a masonry trowel.
