FAQ

You can use the same high-quality fasteners typically used for wood installation. Standard nail guns perform excellently with BOTO Moulding and Trim Boards. Important Note: Never use staples, brads, or wire nails. The shanks of these fasteners are too small in diameter to adequately control the natural thermal expansion and contraction of the PVC material.
No, BOTO Moulding and Trim Boards are non-load-bearing and cannot be used in structural applications. They are designed strictly as decorative components. For any structural requirements, proper wood or metal load-bearing components must be incorporated. Always consult with your architect or builder to determine structural needs before installation
No, BOTO Moulding and Trim Boards usually do not require paint for protection. However, they can be easily painted if you wish to achieve a custom color match for your project or to neatly conceal filled nail holes.
For white or light colors, we highly recommend using a premium, 100% acrylic latex paint specifically developed for trim applications. Several paint manufacturers offer exterior coatings designed exclusively for PVC trim and mouldings. For darker colors, it is crucial to use paints explicitly labeled as “vinyl safe” or “heat reflective” to prevent heat buildup
We offer a comprehensive portfolio of premium PVC extruded products which are used for various applications such as signage and printing, cabinet making, outdoor furniture, agriculture, RV and building materials, organized across four key sectors: PVC Sheets, PVC Trim & Moulding, Vinyl Fencing & Railing, and Vinyl Flooring.
