For smaller areas and detailed work, a brush or roller is usually the best option. For larger areas, an airless sprayer can save you time and effort. Apply the Boscolastic in even coats, making sure to cover the entire surface completely. Pay close attention to corners, edges, and joints, as these are common areas for water leakage. Overlap each coat slightly to ensure a seamless membrane.

5. Number of Coats: Typically, you'll need to apply two or more coats of Boscolastic to achieve the required film thickness. Check the product data sheet for the recommended number of coats and the minimum drying time between coats. Allow each coat to dry completely before applying the next one. This is important to prevent the formation of blisters or other defects in the membrane. Use a wet film thickness gauge to ensure that you're applying the correct amount of material with each coat.

6. Drying and Curing: Once you've applied all the required coats, let the Boscolastic dry and cure completely. The drying time will depend on the temperature and humidity, so check the product data sheet for guidance. Avoid walking on or exposing the membrane to water during the curing process. Once the Boscolastic is fully cured, it will form a flexible, watertight seal that protects the underlying structure from water damage.

7. Clean Up: After you are done, clean your tools and equipment immediately with the recommended solvent. Dispose of any leftover material properly in accordance with local regulations.
