We will not accept an order unless client has seen a physical sample with color requested and signed off on. NOTE: we attempt to replicate orders to samples provided, but since samples are such a limited small field, all production parameters are different from sample making parameters, and due to variation of wood and species, the order will never be a perfect match. Approval of samples, does not bind Crucible to provide customer with an exact replica and Crucible does not guarantee that the sample will be and exact match on final products. Grading Consistency is unmatched. However, each board has a different color variation and each wood takes finishes differently. The sample board may vary slightly from the end product. Customer can expect that the wood type, finish, grading, and millwork of the sample board will align with the end product.

Wood is a natural material and will always expand, contract, and move over time. Properly installed materials may experience some dimensional movement over time, which is not covered by this warranty. Color tones and grain variations in all wood is a natural occurrence due to species, age, and character with exposure to heat, UV light, rain, snow and sunlight. For these reasons, new and/or replacement material will never exactly match samples, photos, or existing installations. Crucible is not responsible for color, grain, or finish variation of product samples for the end user attempting to match other products with millwork, trims or moldings. Natural wood characteristics such as variation of grains, color tones, streaks, and knots are not considered defects, as long as they are within grading rules. Normal exposure to all weather elements, will bring about changes in tones/shading of ANY wood materials as time goes by. These are not product defects. Damage due to all weather, moisture, including but not limiting to broken or leaky pipes, extreme weather or any natural disasters, scratches, stains or damages caused by negligence, fire, water, moisture, excessive heat, dryness, erosion, sand or any other abrasives, animals, insects, conditions of all weather types, natural wood characteristics, failure to follow the manufactures written installation and/ or maintenance instructions, misuse or improper alterations of the manufactured product is excluded from our warranty.

Our products are either air, sun or kiln dried depending upon the materials of choice.

Wood materials will acclimate to moisture content for each location. We recommend all installations or finishing to be completed by a certified building professional with siding or finishes. Product should be face-nailed with 2” minimum stainless rim-shank nail to minimize any movement. Installation should be screen-walled for exterior applications, and seasonal movement taken into consideration. Proper flashing, trims and caulking standards should follow.

Finish Information and Maintenance:

Chatsubu, is a burned exterior or interior siding product that is maintenance optional. Wood siding is a produced material that can be degraded over time by natures outdoor elements. The client can choose to let the materials patina over decades or to re-finish the material keeping the color tones without patina from elements of nature.

Alligator skin or strait burn will keep its black tone for decades before the soot layer wears off, and can have an exterior UV finish added every few years to keep even longer. For our exterior finish product, we use an American made finish by Dalys called Ship' N Shore with and exterior UV added as protectant. On top of the UV protection, this product hardens the wood from 15-25% more, by bonding with the surface. Because of its deep penetration, it leaves no surface film to chip, crack chalk, blister or peel. It is a top of the line conditioner for most wood applications. This product also is very easy compared to competitors to re-apply every few years to keep a lifetime warranty granted by Crucible and our Chatsubu product line. If client keeps documentation showing that this has been applied no more then every 3-4 years, and if for any reason, product fails, with the proper documentation, Crucible will

fully warranty the product.

Speed of patina depends on factors such as pigment color, method of application, nature of wood, weather exposure and maintenance. To get the maximum lifetime as with any wood product with exterior application, we recommend every 3-4 years to reapply ship' n shore with the UV additive by a licensed contractor.

Within 5 years, depending on weather conditions, placement of sun, materials can create hairline cracks and color will start to change w/ no re-application. The client at this point should make the choice to let the product naturally patina over time and enjoy the

process of aging over the decades, or to re-apply the finish. With re-applying, will fill in the hairline cracks, and keep original tone for years. Each re-applied coat over the eyars will last even longer then the original coat due to the build up of finish. Another thing to consider is w/ certain color tones, they will erode and lighten over time but will never flake, peel, chip, crack, chalk or blister.

With proper documentation, Crucible will warranty the product for 50 years if client chooses to keep original tone and colors of wood.

If client chooses to let the product patina with weather over the decades, the 50 year warranty of color tone is null
