Step 2: Seal Cut Edges
James Hardie requires that all cut edges of the siding be sealed with paint, primer, or caulking, even if
the siding is protected by a J-trim. This helps to prevent water intrusion and prolong the lifespan of the

with precision to ensure a neat and seamless fit around the windows. Use a sharp blade or saw to make clean and
accurate cuts.

behind the siding and causing damage. Install Z flashings around the window openings, ensuring that they are
properly aligned and securely fastened.
