Blend the Dry Mortar Mix
Choose whether to use a mortar mix, or make your own mortar from scratch using Portland cement, fine masonry sand and clean tap water.
For larger jobs that might require multiple mortar batches, using a mortar mix may can ensure that the mortar has a consistent strength and appearance. Check manufacturer&#;s instructions as not all mix ratios or mixing times are the same. Different types of mortar mix have different strengths to withstand compressive loads.
If you&#;re doing a smaller job or want to save money, make the mortar from scratch.
- Begin by dry mixing the cement and sand. Use a separate mixing container for the dry components. The standard mortar mixing ratio is one part Portland cement to three parts sand. This varies depending on the type of mortar you need for your job.
- Add the sand to the concrete and use a mortar trowel or hoe to fold them together. Ensure the concrete and sand are completely mixed.
- Some types of mortar include hydrated lime in the dry mix. This makes the mortar more workable during application and more waterproof after it sets. If you want to include lime with mix made from scratch, use it to replace about 10% of the cement.
Avoid inhaling particles from the mix and keep them off your eyes or skin. Wear safety goggles, work gloves, long sleeves and a respirator mask. Mix the mortar outdoors if possible, and ensure that the wind is blowing away from you.
Pro Tip: Before adding the sand, sift it through a 1/4-inch wire screen to filter out any bits of stone that will be too large or coarse for the mortar.
How Do You Make Dry Mortar Mix?
Dry mortar is a combination of mixed raw materials such as sand and cement in dry form. This can also contain additives as well as polymers. Dry mortar is used in construction such as joining bricks together for a sturdy wall. Wet mortars are ready to use and only need to be mixed but this guide will help you make your a DIY dry mortar mix.
Materials
You will need the following materials to make a dry mortar mix:
Portland Cement Bags
Builder&#;s Sand
Water
Equipment
Ensure that you have the proper safety equipment before you start marking your mortar mix as well as the equipment needed to mix your materials. You should have the following:
Prepping the Area
Begin by laying down a tarp over the surface you&#;re going to work on. This will make it easier to work without worrying about spills. Place your mixing board on top of the tarp, brushing it with water to ensure it&#;s clean.
Ingredient Ratios
Fill 3 separate buckets with masonry cement, sand, and water. Standard dry mortar mix consists of a ratio of 3-4 parts sand to 1 part cement. This ratio will vary a bit depending on if the mortar is intended for structural brickwork, internal brick walls, or concrete bricks.
How to Mix Mortar
Mix your dry ingredients inside the wheelbarrow with a shovel to make a dry mix. After adding a small amount of water, continue mixing. Use the shovel to scoop up sand and cement that&#;s left on the bottom to ensure it all gets mixed in. Stab the pile to make sure water is completely absorbed.
The most important thing is to avoid making the mix too wet or too dry. You want to keep repeating this process. Keep adding water and mix until you get the desired smooth consistency and holds its shape.
Transfer the mortar to a mud board. Wet the board before adding your mixture on top. To mix even more thoroughly, use a trowel in folding and chopping motions, checking if you need to add water again. After you transfer your mixture from the wheelbarrow, wash it out before it dries.
Use the trowel to make a hollow in the centre, scoop materials from the outside and fold them into the centre. Finish by chopping the surface to work moisture through to the bottom. Continue this process until you reach the right consistency. If you&#;re creating this mortar mix for a large project, you may benefit from using a mixer.
Cleaning
As well as cleaning excess mortar out of your wheelbarrow before it dries, you want to do the same to your tools. Use a power washer or hosepipe to wash the mortar away and the use of a stiff bristle brush can aid in scraping it off.
Conclusion
Once you&#;re done mixing your mortar, you have about an hour to an hour and a half to use it, depending on temperature conditions. If it&#;s extremely hot, it may last for a little less than this. Past 90 minutes, mortar begins to lose some of its characteristics and should be thrown out.
