How and where to use guide
Soft Building Sand 25Kg Mini Bag
Primary applications
This soft building sand is designed for mortar production in general masonry work. It is suitable for laying bricks and blocks in new construction or repair work, and is particularly well-suited to pointing and repointing tasks where you need to fill or refresh joints between existing masonry units. The 25kg format makes it practical for smaller projects, patch repairs, or workshop-based work where you do not require bulk quantities.
- Brickwork: laying bricks in new walls or repairs
- Blockwork: laying concrete blocks and similar units
- Pointing and repointing: filling and finishing mortar joints
- General masonry repairs and maintenance
Mixing and workability
The sand is graded to suit standard mortar mixes. Combine it with cement and lime according to your specification, typically in ratios such as 1:3 (cement:sand) for stronger mortars or 1:2.5:8.5 (cement:lime:sand) for more flexible lime mortars. Mix thoroughly to ensure even distribution and consistent workability. The grading of this soft building sand provides good workability, allowing the mortar to spread smoothly and bond effectively to masonry units.
- Follow your project specification for cement and lime ratios
- Mix thoroughly in a mortar mixer or by hand until uniform
- Add water gradually to achieve the correct consistency
- Use mixed mortar within the working time specified by your cement supplier
Handling, storage and site tips
The 25kg mini bag format is designed for ease of handling and portability on site or in the workshop. Store bags in a dry location away from standing water and excessive moisture, as damp sand can affect mortar performance. Keep bags off the ground where possible to prevent water ingress. Check the bag for damage before use. On site, keep sand covered during wet weather to maintain consistent moisture content, as this affects mortar workability and strength development.
- Store in a dry, sheltered location away from rain and standing water
- Keep bags off the ground to prevent moisture absorption
- Cover stockpiles during wet weather to maintain consistent moisture
- Inspect bags for damage or contamination before opening
- Use sand within a reasonable timeframe to avoid prolonged storage
Limitations and best practice
Soft building sand is formulated for standard mortar mixes and general masonry applications. Do not use this product for concrete production, screeds or other applications outside mortar work. Ensure the sand is free from excessive clay, silt or organic matter before use, as these can compromise mortar strength and durability. Always follow the mortar specification for your project, which may be determined by the masonry unit manufacturer, structural engineer or building control requirements. Weather conditions affect mortar curing; avoid laying masonry in freezing conditions or heavy rain.
- Use only for mortar production in masonry applications
- Not suitable for concrete, screeds or other uses
- Verify sand quality and cleanliness before batching
- Follow project-specific mortar specifications
- Avoid laying masonry in frost or heavy rain
