primer slurry test which is best  

Here are the steps to apply a slurry primer:
1. Clean the surface: The concrete surface must be clean and free of any debris, dirt, or oil. Use a pressure washer or a scrub brush to clean the surface thoroughly.
2. Mix the slurry: Mix the slurry primer according to the manufacturer's instructions. The consistency should be similar to that of pancake batter.
3. Apply the slurry: Use a brush or a roller to apply the slurry primer to the concrete surface. Apply it evenly, making sure to cover the entire surface.
4. Allow the slurry to dry: The slurry primer should be allowed to dry for at least 24 hours before applying the topcoat or overlay.
5. Apply the topcoat or overlay: Once the slurry primer is dry, you can apply the topcoat or overlay. The slurry primer will help the topcoat or overlay adhere better to the concrete surface.
Slurry primers are commonly used in concrete resurfacing projects, such as when applying a decorative overlay or a stamped concrete finish. They help to create a strong bond between the concrete surface and the topcoat or overlay, ensuring a long-lasting and durable finish.
