Have you ever countered whitish patches appear on the colored mortar?
(Flow & Levelling)
Coloured mortar is made with a combination of Portland cement, hydrated lime, sand and colour pigments. After sometime, a whitish colour salt deposits (efflorescence) may appeared on the surface of coloured mortar and caused discoloration. Repair and cleaning work are required to restored the colour mortar to their original colour which cost money.
Efflorescence is caused by water-soluble salts present in the mortar. When rain water or ground water migrated into the mortar, it dissolved the salts and carry them to the mortar surfaces. The moisture will then evaporated off and cause the salts to crystallize and deposit on the surfaces, resulting in efflorescence.
