All manufacturers have different setting and mixing instructions, so it’s important to always follow the instructions on the bag. Make sure not to make more than you can use in about two hours, as the mortar will set quickly. Adding lime to the mortar will improve its workability, make the mortar more water resistant, and will reduce the amount of shrinkage upon curing. Lime also helps prevent the cement and sand from separating. If you want to add lime to your mortar, replace about ten percent of the Portland cement with hydrated lime. {“smallUrl”:“https://www. wikihow. com/images/thumb/0/06/Mix-Portland-Mortar-Step-2Bullet1. jpg/v4-460px-Mix-Portland-Mortar-Step-2Bullet1. jpg”,“bigUrl”:"/images/thumb/0/06/Mix-Portland-Mortar-Step-2Bullet1. jpg/aid1375402-v4-728px-Mix-Portland-Mortar-Step-2Bullet1. jpg",“smallWidth”:460,“smallHeight”:345,“bigWidth”:728,“bigHeight”:546,“licensing”:"<div class="mw-parser-output">

Most mortar should have the consistency of peanut butter. Once you have mixed the mortar, add any liquid additives and distribute them evenly through additional stirring. Clean your mixing tools at this time so that the mortar does not cure on the tool. Run clear water over the tool and rub with your gloved hand until all the mortar is removed.
