How to Prepare for Mortar Mixing

Mortar is usually used as a binding material used to repoint brick walls on a house or other brickwork. It is a good all-rounder adhesive that is used when constructing walls for a house or a garden. It can also be used as a filler between bricks and stones that have been laid on a garden path.

To prepare for mixing mortar, you must ensure that you have all of the tools, materials, and safety equipment needed to effectively and safely complete the job.

Before you start to mix the mortar, you should put on your safety goggles and dust mask so that you are completely protected from the start.

Make sure you have your wheelbarrow and mud board ready so that the mortar can be mixed and transferred quickly.

How to Mix Mortar Yourself

Below is a step-by-step guide on how to mix lime mortar by hand. Although if you prefer to hire someone to do any repointing on your behalf, they will either use the same method or bring a cement mixer to use on site:

Step 1

Empty the package of mortar mix into your wheelbarrow being careful not to overspill it. If you are not using a pre-made mortar, then take the binding agent (for lime mortar, this would be a lime putty) and mix with sand prior to the next step.

Step 2

Add a small amount of water to the wheelbarrow. It’s important that you don’t begin by adding too much water as this can ruin the consistency and you will have to start again. You should focus on adding the water in gradually.

Step 3

Once you have added some water, use the shovel to lift the mortar mix over the water. Concentrate on lifting the back and sides of the mix over the water and fold it all together.

Step 4

Once all the water is mixed in, add some more water and repeat the above step. Continue to fold the mix over and combine it with the water and spread it through the mixture evenly. Continue adding and folding in water until it reaches the right consistency.

Now, add some water to your mud board before transporting your mortar mix over to it.

Step 6

Check the consistency of the mortar mix on the mud board. If it is too hard, create a circle in the centre of the pile of mortar and insert some water into this central hole. Then start piling the mortar from the outside into the centre and continue this until the water is all mixed in.

FAQs

How Long Should I Mix Lime Mortar by Hand?

Lime mortar can be mixed by hand or in a cement mixer. You should mix the mortar for five minutes and allow it to rest for three minutes, then go on to mix it for another three minutes for the best results.

How Do You Mix Mortar in a Bucket?

Pre-wet your bucket ready for mixing and pour in the appropriate amount of cement, lime, and sand. Add water and fold the mixture from the bottom as you continue until the water is fully mixed in. Keep adding water until the mortar is a smooth consistency. You can stop mixing when the mortar is wet enough to slip off your spade easily, but holds its shape if you hollow out the mixture.

How Long Does Mortar Take to Dry?

This will depend on a variety of factors such as the temperature and humidity, as well as the type of mortar being used. On average, initial setting takes around 48 hours. However, in order for the mortar to reach its full strength, cement-based mortar can take up to 28 days to fully cure, while lime mortar can potentially take even longer.

Can I Reuse Leftover Mortar?

If you are using cement mortar within 30 to 60 minutes of mixing (or around 2 to 3 hours for lime mortar), then you have a small window of opportunity to use leftover mortar elsewhere. However, once it starts to harden the mortar should be disposed of, as if you add extra water at this stage the mixture will become weaker and less practical to use.

How Long Does Mortar Last?

If mixed and applied correctly, mortar can last for decades with little or no maintenance. Lime mortar is especially durable and can last a lifetime with proper care, although weather conditions and moisture levels can impact its actual lifespan.
