Choosing the Right Filler

Selecting the appropriate filler material is essential for the longevity and appearance of the patio. Common options include polymeric sand, joint compound, and mortar. Polymeric sand is a durable and flexible choice that resists erosion and weed growth. Joint compound is ideal for filling narrow gaps and providing a smooth finish. Mortar, a mixture of cement, sand, and water, offers strength and resistance to heavy loads.

Preparing the Gaps

Proper gap preparation ensures that the filler adheres effectively. Use a wire brush or broom to remove debris and loose material from the gaps. Depending on the filler choice, you may need to dampen the gaps with water to create a stable surface for the filler.

Applying the Filler

Follow the manufacturer's instructions for mixing and applying the filler. Use a trowel or squeegee to spread the filler into the gaps, ensuring complete filling. For polymeric sand, water must be applied after installation to activate the bonding agent. Joint compound can be smoothed with a damp sponge.

Curing and Maintenance

Allow the filler to cure according to the manufacturer's guidelines. This curing period is crucial for the filler to develop its strength and durability. Keep the patio out of use during this time. Once cured, the patio should be swept regularly to prevent dirt and debris accumulation.

Additional Tips

For wider gaps, consider using crushed stone or pea gravel as a base layer before filling with sand or joint compound. This provides additional stability and reduces the likelihood of settling. Seal the gaps after filling to protect them from moisture and weathering.
