Mortar matching is the approach of analyzing samples of the mortar to recognize their composition, overall performance, and formula. As the color of sand and other components in the composition impact the colour, they are associated, but the base formula of a mortar composition should be matched before any attempts are made to match the colour of an current mortar.
The mortar composition and formula are the guide to making a right repair mortar and keeping the formula. This is critical because if the mortar is mismatched and has a diverse composition than the original mortar, it can have complications that make the color much more hard to match, bring about damage to the bricks, protect against the new mortar from bonding with the old mortar, and could permit the wall to fall if the mortar crumbles.
The fifth most common mistake in repairing masonry is matching mortar colour. Most of the time the mortar composition evaluation of the original mortar is skipped and general assumptions are produced in its spot. This causes difficulty in matching mortar colour simply because the color is a direct result of the composition and the ratio of supplies in the mortar mix.
