Final Answer:
3 inches of the 6-inch cap sheet end lap are coated in IKO Aquabarrier mastic.
Step-by-step explanation:
The 6-inch end lap of the cap sheet indicates the total overlap between two adjacent sheets. Within this overlap, half of the area, which is 3 inches, is coated in IKO Aquabarrier mastic.
This mastic is applied to seal and protect the joint, ensuring water resistance and enhancing the durability of the roofing system. It serves as a crucial barrier against moisture infiltration, safeguarding the underlying structure from potential damage caused by water ingress.
IKO Aquabarrier mastic, when applied correctly, adheres to the surface and forms a robust, waterproof seal. Its application over half of the 6-inch end lap area is designed strategically to fortify the seam between roofing materials.
This adhesive and protective layer contribute significantly to the overall integrity of the roofing system, particularly in areas prone to water exposure and potential leaks.
