To make mortar for brick, you’ll need to combine one part hydrated lime, two parts wood ash and four parts sand. In addition, you can add one part cement to the mix. If you are using a commercially made brick mortar mix bag, it should have a ratio of 1:6 cement:sand on the back of the bag.
Mixing Mortar
Mixing mortar is a two-step process. First, you add water to the mix. You should use enough water to make a thick paste; if you add too much, your mortar will be weak and crumbly when it dries. If you add too little, however, then you’ll end up with dry pockets of brick dust in your finished product.
Next comes the mixing itself—you need to get all of the components thoroughly combined as quickly as possible so that they start setting up as soon as possible. A good rule of thumb is that if there are any traces of powder or chunks left after mixing them together properly and stirring until they are fully dissolved into liquid form (about 15 minutes), then something went wrong during either adding water or mixing it all together at once using a manual mixer like this one: http://amzn.to/2Dx4gwQ
Cement and sand have different weights and can settle at different rates when mixed. So, make sure to mix the materials slowly to achieve a mixture that is consistent.
When mixing mortar, you want to make sure that the consistency is even throughout. To do this, use a drill with a mixing paddle attachment or a mixing tool that can be fitted on the end of your drill. Mixing slowly ensures that you don’t get too much cement and sand in one area or too little in another.
If your mixture is too wet, it will not set properly and may begin to separate as it dries out. A good rule of thumb when mixing mortar is if you feel like there are still lumps of dry material in your mix after adding water and stirring, then it’s probably not ready yet.
Trying to make mortar too dry will cause the pieces to crumble.
Mortar is a mix of cement, sand and water. The ratio can vary from 1:1 to 2:1 in favor of water. If you are building a small wall and only need enough mortar to fill the gaps between bricks, a ratio of 1:2 may be sufficient. However, if you are building a large retaining wall or patio that requires large amounts of mortar to hold the bricks together while they cure, you should use more sand so there isn’t too much moisture which will cause the mortar to crumble when it dries out after construction is done.

Trying to make the mortar too wet will cause air bubbles to be trapped.
- If you make the mortar too wet, it will be difficult to work with. The mortar will be weak and will not hold together well at all.
- Making a wet mix also makes it difficult to spread the mortar over the bricks, as they tend to slide around in wet mixtures.
- Making a very wet mixture can cause air bubbles to be trapped inside of the material, which means that when it dries out those air bubbles remain, leaving holes in your brickwork. This is more likely when working with clay bricks because these bricks are porous by nature and allow water molecules into their structures easily; this allows for an even faster drying time than normal cement-based mortars would usually have on their own.
Hydrated lime will be the easiest material to add if you are trying to make mortar for bricks wetter than it is. For example, if you accidentally make your mortar mix too dry, you add hydrated lime.
If you find that the mortar is too dry, you can add hydrated lime to make it more wet. Hydrated lime is a powder that will help give the mortar some extra wetness.
You can also use cement as an alternative to hydrated lime! Cement makes strong structures and tends to be more expensive than other materials used in making bricks, but it has many benefits that make it worth using! Sand is another material often added to mortar mixes so they’re easier to spread on surfaces like walls or roofs when laying bricks down. The sand adds weight and texture which helps hold each brick together while also helping them stay put once they’re placed correctly.”
Brick mortar mix bags contain varying ratios of mix with cement, sand and hydrated lime.
You can determine the ratio of mix that you need by reading the label on a brick mortar mix bag. This will tell you how much material to add to each recipe and what materials are required in order for it to work correctly. The dry cement is added first and then followed by the sand and hydrated lime.
The materials must be mixed thoroughly with water so that they form a thick paste-like consistency before being poured into molds or forms as per your instructions from your supplier/contractor. If there is too much liquid, then your mortar will not harden properly and could fall apart during removal from its mold after curing for several days in normal conditions (i.e., temperatures between 50 degrees F – 110 degrees F). If there is too little liquid, then your mortar will become very hard but will not cure properly; this may lead to cracking while drying out or even falling off floorboards when walking over them after curing for several days at normal conditions (i.e., temperatures between 50 degrees F – 110 degrees F).
You should always have extra bags of sand or cement handy because if something goes wrong with one batch of mix made according to instructions given on labels placed on bags containing these materials before mixing begins. It’s also recommended that you wear protective clothing when working with them since both contain fine particles which may cause irritation if inhaled directly into nostrils etcetera.”

Conclusion
As you can see, preparing mortar is a pretty simple process. The most important thing to be aware of is the consistency of your mix and the ratio of materials you use in order to achieve a desired result.
