3. Mix the primer: Follow the manufacturer’s instructions to mix the primer if necessary. Some primers may come ready-to-use, while others may require mixing with water or a solvent.
4. Apply the primer: Use a brush or squeegee to spread the primer evenly over the entire surface of the driveway. Work in small sections to ensure thorough coverage. Apply a thin and uniform coat, making sure not to leave any puddles or excess primer.
5. Let it dry: Allow the primer to dry completely before proceeding with the chip and seal application. The drying time may vary depending on the primer product and weather conditions. Refer to the manufacturer’s instructions for specific drying times.

By applying the primer, you create a strong bond between the existing pavement and the chip and seal materials. This enhances the longevity and performance of the chip and seal layer, providing a durable and attractive finish for your driveway.

Before starting the chip and seal process, make sure to thoroughly clean the driveway to remove any debris or dirt. This will ensure a smooth and even application of the chip and seal materials.

Step 4: Spread the Chip Seal

Spreading the chip seal is the core step in the chip and seal process. This is where the asphalt emulsion and stone chips come together to create the textured surface. Follow these steps to spread the chip seal:

1. Mix the chip seal: Start by mixing the asphalt emulsion and stone chips in a suitable mixing container. Follow the manufacturer’s instructions for the proper ratio and mixing procedure. The mixture should have a consistent and homogenous texture.
2. Begin application: Pour a portion of the chip seal mixture onto the prepared driveway surface. Use a brush, squeegee, or sprayer to spread it evenly. Work in small sections to ensure consistent coverage.
3. Distribute the stone chips: Immediately after applying the chip seal mixture, spread the stone chips over the surface. Make sure to cover the entire area with a layer of stone chips. The thickness of the chip layer will depend on your desired outcome and the size of the stone chips.
4. Press the chips into the emulsion: Use a roller or compactor to press the stone chips into the asphalt emulsion. This will ensure proper adhesion and create a textured surface.
5. Continue the application: Repeat the process of applying the chip seal mixture and distributing the stone chips until the entire surface of the driveway is covered. Work in overlapping sections to create a seamless and uniform finish.

Spreading the chip seal requires attention to detail and precision to achieve a professional-looking result. Take your time and make sure to evenly distribute the chip seal mixture and stone chips for a durable and visually pleasing surface.
