Mixing mortar correctly is essential for strong and durable brickwork, paving, or repairs. Whether you're using a premixed mortar bag for small jobs or making your own from scratch, getting the right consistency is key. Follow this step-by-step guide to ensure your mortar is mixed properly and ready to use.
Tip: Always wear the appropriate safety equipment (safety glasses, gloves, ear muffs and a mask, for example) and always follow the instructions for the product or equipment.
The type of mortar mix you need depends on the job at hand. For smaller projects, you can use premixed mortar bags. For larger projects, you’ll need to mix your own using sand, cement, hydrated lime, and water. A standard mortar mix generally consists of six parts sand, one part cement, and one part hydrated lime.
The colour of your mortar can also be adjusted based on the materials used. Standard grey mortar is made using regular brick sand and cement mix , while a lighter or cream-coloured mortar can be achieved by using white brick sand and off-white cement mix. If you're after a different look, you can also add oxides to change the colour completely.
You may also consider using mortar waterproofing additives to improve your mortar mix. A plasticiser helps make the mortar easier to work with, while a waterproofing additive helps prevent moisture absorption. Always follow the manufacturer’s instructions when adding these, as too much can weaken your mortar.
To test if the mortar mix is ready, pick up a small amount on a trowel and hold it upside down. If the mortar sticks without falling off, the consistency is correct. If it is too dry or crumbly, add a little more water and mix again. The goal is to achieve a smooth, workable paste that holds its shape when applied.
Too much water in the mix will weaken the mortar and make it difficult to work with, so it’s important to be patient and add water gradually. Take your time mixing to ensure a smooth and even texture. Only mix what you need, as mortar dries quickly, so working in small batches can help prevent waste.
With the right mix and consistency, your mortar will be strong, durable, and easy to apply. Now you're ready to tackle your next project!
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions.
