How to Make Mortar: A Step-by-Step Guide

For centuries, people have been using mortar to build their homes and structures. It’s the glue that holds bricks, stones, and concrete together to produce a sturdy and long-lasting surface. While it might seem like a complicated process, making your own mortar is quite simple. Whether you’re a DIY enthusiast or a professional mason, learning how to make a mortar can save you a significant amount of money in the long run.

Before we dive into the nitty-gritty of making your own mortar, it is essential to understand what exactly it is and why it’s so important. Mortar is a paste-like material that is used to bind together different materials, most commonly bricks or stones, during the construction of a building. It primarily consists of a mixture of cement, sand, and water, along with other additives such as lime. Mortar acts as an adhesive and provides strength to various parts of the structure, ensuring longevity and structural integrity. In this article, we will guide you through the steps of making your own mortar that most closely aligns with your requirements.

1. Understanding Mortar

Before we dive into the process of making mortar, it’s essential to understand what it is. Mortar is a mixture of cement, sand, and water that is used to bind building blocks like bricks, stones, and concrete blocks together. It’s different from concrete as it doesn’t contain any aggregate or reinforcement which makes it weaker. However, it still has excellent bonding qualities and good compressive strength.

2. Pick the Right Type of Cement

Choosing the right type of cement for your mortar mix is important and can determine the strength of your final product. For example, if you’re working on a project that requires a level of waterproofing, you’d want to use hydraulic cement in your mix.

3. Choosing Sand for Your Mortar

Sand is the second ingredient of mortar and plays a significant role in determining workability, water retention, and strength. Ideally, use sand that has a smooth texture and is clean of debris. Moreover, the type of sand chosen depends on the desired mortar texture and strength.

4. Tools and Equipment

Before making mortar, it’s essential to have all the tools and equipment required. Some of the tools include a mixing pan, trowel, measuring tools, gloves, and a mask. Having all the equipment can help speed up the process and produce quality mortar.

5. Mixing the Mortar

Mixing is perhaps the most critical aspect of making mortar as it determines the quality and strength of the final product. When mixing the mortar, the cement, sand, and water should be added in the right proportion. The recommended ratio of cement to sand is between 1:3 and 1:5, depending on the type of application and desired strength.

6. Adding Water to the Mix

Adding water to the mix should be done gradually, as too much water can make the mortar less strong and workable. The amount of water should be enough to make the mix easy to spread and workable, without making it too runny.

7. Testing the Mortar Mix

It’s important to test the mortar mix before using it to ensure that it meets the required standards. The mix should be spreadable and have a smooth texture. Using it prematurely could cause disasters and damage your project.

8. Applying the Mortar

After mixing the mortar, you need to apply it to your building blocks immediately. It’s essential to spread the mortar evenly, leaving a 10mm gap between the blocks. This gap allows for the settling of the blocks and the expansion and contraction of the mortar.

9. Washing Off Excess Mortar

After applying the mortar, don’t forget to clean off any excess mortar using a wet sponge. It’s essential to do this while the mortar is still fresh before it hardens into a crust.

10. Curing the Mortar

Curing the mortar is the final step in making sure your project has a strong and durable foundation. It involves keeping the mortar moist and covered from direct sunlight for at least 7 days. Curing helps improve strength, durability, and resistance to weather conditions.

Conclusion

Making mortar is much more than just mixing cement, sand, and water. To create a quality and durable mortar, you need to choose the right materials, understand the mixing process, and take all the necessary steps to ensure that the final product meets all required standards. Follow these steps carefully, and with patience, you are sure to build with mortar like a pro.

What you will need to make mortar

Now that you know what mortar is, it’s time to learn how to make it. Here are the things you will need:

1. Portland cement – This is the main ingredient in mortar and can be found in most hardware stores or online.

2. Sand – You will need sand to mix with the cement. Look for a sand that is fine, clean, and free from debris.

3. Water – You will need water to mix the cement and sand together. Use clean water from a hose or tap.

4. Mixing container – You’ll need a container to mix everything in. A wheelbarrow or large bucket works well.

5. Mixing tool – Use a mixing tool such as a hoe, shovel or drill mixer to combine the ingredients.

6. Protective gear – It’s important to wear gloves and a mask when handling cement as it can irritate the skin and lungs.

7. Measuring tools – You’ll need measuring tools such as a bucket or measuring cup to ensure you’re using the correct proportions of ingredients.

8. Trowel – You’ll use a trowel to apply the mortar to your brick or stone.

9. Mortar board – This is a flat surface, made from wood or metal, that you use to hold and mix the mortar.

10. Cleaning tools – Keep a bucket of water and sponge nearby to clean up any spills or mistakes.

Now that you have everything you need let’s get started on making the mortar!

Mortar Ingredients

Mortar is a mixture of different ingredients that work together to create a cohesive and durable building material. The three basic ingredients of mortar are cement, sand, and water. There are also two commonly used additives that can be mixed into mortar to enhance its performance: lime and plasticizer.

Cement

Cement is the main binder in mortar. It is a fine powder that is made by heating limestone and other materials at high temperatures. When mixed with water, cement forms a paste that hardens over time. Portland cement is the most commonly used type of cement in mortar.

Sand

Sand is the aggregate component of mortar. It is usually composed of fine rock particles, such as quartz, that range in size from 0.1 to 2.5 millimeters. The type of sand used in mortar should be clean, free of debris, and well-graded to ensure good workability and strength.

Water

Water is added to mortar to activate the cement and make it workable. The amount of water used affects the consistency and strength of the mortar. The ideal water to cement ratio for most mortar mixtures is around 0.5:1 by weight.

Lime

Lime is an optional additive that can be mixed into mortar to improve its workability, durability, and water resistance. Lime acts as a plasticizer, making the mortar more flexible and easier to work with. It also helps to prevent cracking and shrinking by reducing the amount of water that is absorbed by the mortar.

Plasticizer

Plasticizer is another optional additive that can be mixed into mortar to improve its workability and reduce the amount of water required. It is a liquid that is added to the water used in the mortar mixture. Plasticizer helps to reduce the stickiness of the mortar and make it easier to spread and work with.

In conclusion, a good quality mortar depends on the correct ratio of the ingredients used. It requires careful attention to detail when mixing and applying it. The right combination of cement, sand, water, and optional additives like lime and plasticizer are necessary for producing a durable and long-lasting mortar.
