Mortaring pavers involves carefully applying mortar to a base and setting the pavers in place to create a durable and aesthetically pleasing surface. Here's a step-by-step guide:
1. Prepare the Base:
- Ensure you have a solid, level base. This usually consists of a compacted gravel layer followed by a sand or setting bed. The specific composition depends on the intended use and local conditions.
- A concrete slab can also act as an ideal base for mortar-set pavers.
2. Prepare the Mortar:
- Mix the mortar according to the manufacturer's instructions.
- The ideal mortar consistency should resemble moulding clay - plastic and workable, but not too wet or dry.
3. Apply the Mortar:
- Using a trowel, spread a layer of mortar approximately 20mm (about 3/4 inch) thick onto the prepared base where the paver will be placed. Only mortar an area you can work with in a reasonable timeframe before the mortar begins to dry.
4. Set the Paver:
- Carefully place the paver onto the mortar bed.
- Use a rubber mallet to gently tap the paver into position. Ensure the paver is level with adjacent pavers and any established string lines used as guides.
- Continuously check the level and alignment of the pavers.
5. Spacing and Joints:
- Maintain consistent joint spacing between the pavers. You can use paver spacers to achieve uniform gaps.
- The joint width will depend on the aesthetic you desire and the type of paver.
6. Curing and Cleanup:
- Allow the mortar to cure according to the manufacturer's instructions. This typically takes several days. Keep the area lightly dampened to prevent the mortar from drying too quickly.
- Once cured, fill the joints with grout or polymeric sand designed for paver applications. This will help lock the pavers together and prevent weed growth.
- Clean off any excess mortar from the paver surfaces with a damp sponge before it hardens completely.
Important Considerations:
- Weather: Avoid mortaring pavers in extreme heat or freezing temperatures.
- Safety: Wear appropriate safety gear, including gloves and eye protection.
- Drainage: Ensure adequate drainage to prevent water from pooling and damaging the pavers or mortar.
- Mortar Type: Select a mortar specifically designed for paver installation.
- String Lines: Using string lines as guides helps maintain straight lines and consistent height across the paved area.
