Can you pre cut areas and let dry and then roll, will paint match color? Or does it have to be applied all at one time to match?

Thank you for your question. Shake and stir thoroughly before and during use. If project requires more than 1 container, blend all containers together to ensure uniformity. Working in small sections at a time (1–3 boards), use a nylon/polyester brush to dab DeckCorrect™ into cracks and rough areas before rolling. Use a 3/8- inch nap roller to apply a thick, even coat, rolling lengthwise along boards. Allow to dry 4–6 hours before applying second coat. Requires a 2-coat application.
