Our contractors tell us 30-45 days after it can be sealed.

Hello Alex, 

We are one of the largest James Hardie Siding Elite Preferred contractors in Maryland and we have done numerous James Hardie installs. We have used this application before; it is called a compound miter. Due to the angle of the siding you will first need to determine the angle at which the siding sits on the house wall, which is typically between 10-15 degrees. The actual corner should be at a 45 degree angle. We have found the easiest way to do this is to begin at the bottom course using short pieces to determine the angle. If you need additional information please do not hesitate to contact us 301-355-4604.

Thank you!
