The Concrete Art series "Cedar Board Float Design" uses real cedar boards (uzukuri processing) to replicate the wood grain (annual rings) of cedar on the wall's mortar using a "patented technique." Furthermore, it is colored in a concrete-like hue and features wood grain (annual rings) painting, restoring it to a cedar board concrete exposed finish. Additionally, the depth of the cedar wood grain's relief (carving depth) can be adjusted, with options for cedar carving processing: single pass (shallow), double pass (slightly deeper), triple pass (deeper), and maximum range carving (extremely deep). Coloring can also be done in your preferred color. Regarding durability, a protective clear coating (water-based fluororesin) finish is applied, ensuring high durability and peace of mind. 【Features】 ■ Colored in a concrete-like hue with wood grain (annual rings) painting ■ The depth of the cedar wood grain relief can be adjusted ■ High durability and peace of mind due to the protective clear coating finish ■ Applicable for both indoor and outdoor installations *For more details, please refer to the related links or feel free to contact us.

The Sanwa Construction Company utilizes its unique special plastering technique to create the Concrete Art Series: "Cedar Board Floating Texture Design Panel Method (Patent Pending)." Note 1: Compared to large-scale on-site construction methods like "Cedar Board Formwork Concrete Method," this method primarily involves simply screwing panels into the wall substrate (Note 2), making it easy to establish walls with a cedar board floating texture. (There will be repairs for the screw holes after installation.) Note 1: Indoor specifications (for interior use only) Note 2: Wall substrate (studs, battens, boards) The panels of this product are carefully crafted with mortar to transfer and shape the cedar wood grain, with unique adjustments to the depth of the grain's texture and color, providing realistic coloring and artistic application. *As this is made to order and finished by hand, please consult us early. 【Reasons to Choose Us】 ■ Unique and meticulously designed aesthetics ■ Can be applied to just a corner of a building's entrance or similar areas ■ Creates a high-quality space with unique wood grain textures and colors not found in panels or wallpaper ■ Suitable for both new construction and renovation projects ■ Significantly contributes to shortening construction time *If you would like a catalog, please feel free to contact us. *The downloadable material is a catalog for the on-site construction type of floating texture.

I would like to introduce you to "How to Identify Cedar Board Formwork Concrete Method" from Sanwa Construction, which addresses all concrete troubles, from the beautification of newly built houses to aging deterioration of fences, so that you can avoid losses! The downside is that since concrete is poured into cedar board formwork for a one-shot finish, you cannot know the outcome until the formwork is removed. The reason is that the cedar board absorbs moisture from the fresh concrete, causing the cement paste to stick to the formwork and peel off, or not transfer well. Furthermore, it is very difficult and high-risk as poor finishes like honeycombing and surface defects can occur. Additionally, since concrete needs to be poured, the construction conditions are limited, leading to high costs. The level of finish also varies by contractor. When considering cedar board floating, be sure to check the following points! 【Verification Items】 ■ The level of finish color expression ■ Whether there is technology for adjusting the texture of the wood grain ■ The neatness of the wood grain joints in construction case photos ■ The know-how and knowledge of plastering techniques ■ Whether mortar construction can be used as an alternative to concrete *For more details, please refer to the basic information at the bottom of the screen.

Using the "Cedar Board Floating Grain Design Panel Method," which was our first attempt, we applied a concrete-colored wood grain design to the walls of the Mitsukoshi Isetan Shinjuku store, completed in December 2019. [Customer Requests] - We would like the cedar board wood grain to be designed in a concrete color. - We hope for a deeper and clearer carving of the cedar board floating grain. - We want to eliminate seams to avoid patchy wood grain. - Please finish it in a way that prevents our customers' clothing from getting dirty with mortar or snagging. - We would like you to accommodate us despite the limited construction time and difficulty of on-site work. Using our unique technique (patented product), we sculpted the cedar board floating grain in mortar, carefully transferring a seamless cedar board wood grain, mixing colors uniquely, and applying color and wood grain drawing by hand, resulting in panel products. On-site, we ensured that the panels could be fixed with screws. After installation, we performed local repairs and finishing to complete the project. *This contributed to shortening the construction period. Normally, on-site painting requires a curing period, which takes time. Compared to that, the construction period was significantly simplified. *For more details, please download the PDF or feel free to contact us.
