Frequently Asked Questions About KOMA® Trimboards


What makes KOMA Trimboards the ideal replacement for wood or other alternatives?

KOMA Trimboards is an extruded PVC product and will not be affected by moisture. This means the boards will not warp, cup, twist, or rot. KOMA Trimboards are also impervious to salt and insects and will never need to be replaced.

How do I fasten KOMA Trimboards?
You can use nails, screws, and construction adhesives to fasten KOMA Trimboards to wood, masonry and other materials and surfaces. When you want KOMA Trimboards to adhere to each other, use KOMA Bond and Fill for an excellent bond and a perfect color match. You can also use PVC cement or a high quality polyurethane adhesive. Do not use a silicone based product.

What fasteners can be used with KOMA Trimboards?
Any rust-proof woodworking fastener will work with KOMA products. We recommend stainless steel. Hot-dipped galvanized fasteners can also be used. KOMA products do not require pre-drilling unless large fasteners are used or the product is installed in low temperatures. KOMA Trimboards work well with finish nail guns using rust-proof nails. Avoid using fine-threaded wood screws or ring-shank nails. Fill fastener holes with KOMA Bond and Fill.

What cleaners are recommended for use with KOMA Trimboards?
Household cleaners such as Clorox® Cleanup or Soft Scrub should remove most common soils and stains. For more stubborn situations, Clorox® Outdoors is recommended. Use with a stainless steel brush and scrub with the grain. Do not use cleaners containing acid or solvents like MEK, acetone, or toluol. Ground in or abraded stains can be removed with 100 grit sandpaper. Lightly sand with the grain until stain is removed.

Will KOMA Trimboards take paint?
KOMA Trimboards are UV-resistant and do not require paint for protection. They may be painted to achieve a custom color and the special proprietary surface allows paint to bond better than with all other PVC products. Use interior or exterior 100% acrylic latex paint. Avoid painting KOMA Trimboards surfaces dark colors in areas of direct sunlight. (Don’t exceed #65 on the light reflective scale).
