  • Packaging prefinished fiber cement articles
    Patent number: 8281535
    Abstract: Protected prefinished fiber cement articles are manufactured by applying a protective layer on the finished surface of a fiber cement article. The protective layer protects the finish layer of the prefinished fiber cement article during handling, storage, and transport. Removing the protective layer leaves no residue on the finish layer, does not damage the finish layer, and does not substantially tear the protective layer. Protected prefinished fiber cement article are typically stacked on pallets for storage and transport. Optionally, spacers may be placed between the stacked protected prefinished fiber cement article.
