THE KOMA PREMIUM SURFACE                                                                                                                                 

There are a number of different types of PVC trim board available on the market today.  KOMA is a global producer of PVC foam board. KOMA is a world leader in the technology of the two leading manufacturing processes for the manufacturing of PVC trimboard. KOMA chose to make their trimboard out of the CELUKA process produces a denser surface. By making the surface more dense it is harder and less likely to scratch and show minor surface dents and imperfections.  The CELUKA manufacturing process also allows KOMA to add a propriety surface finish that gives the KOMA trimboard a far superior surface to accept latex paint if the user so desires.  This surface also allows for the acceptance of paint without the need for a primer being applied.  KOMA does not require paint, but should you desire to paint it, KOMA felt that providing a premium surface for paint adhesion was best.

STORAGE AND HANDLING

When storing KOMA trim products lay them on a level and flat surface. If stored on uneven surfaces KOMA may conform to the surface on which it is stored.

ü       KOMA is a premium trim product; it should be handled with care to avoid damage. 

ü       KOMA is shipped in a protective covering. Try to keep KOMA covered and free of dirt and debris at jobsite. If KOMA gets dirty, clean after installation. Products like soft scrub  with a nylon brush do an excellent job restoring KOMA to its original manufactured state.

CUTTING

ü       KOMA products can be cut using all types of saws, (Circular, Band, Saber, Table, Panel or Gang Rip)

ü       Good quality carbide tipped blades work best. Do not use fine tooth metal cutting blades.

DRILLING

ü       Use standard wood drills to drill KOMA products.  .

ü       When drilling KOMA products be careful to avoid frictional heat build-up.

ü       Drills ground for rigid PVC are not recommended for KOMA.

ROUTING

ü       Use standard router bits when routing KOMA products.

ü       KOMA routs best with carbide tipped router bits.

ü       KOMA products will have a crisp, clean edge after routing.

FASTENING

ü       Any woodworking fastener will work with KOMA products.

ü       When you want KOMA trimboard to adhere to each other, use PVC cement.

ü       KOMA recommends a high quality fastener such as stainless steel or hot dipped galvanized.

ü       KOMA trim products work well with nail guns

ü       KOMA recommends using finishing nails.

ü       KOMA recommends avoiding fine threaded wood screws and ring shank fasteners.

ü       KOMA does not require pre-drilling unless a large fastener is used or product is installed in low temperatures.

PAINTING

ü       KOMA products do not require paint for protection, but may be painted to achieve a custom color.

ü       KOMA has a special proprietary surface that allows it to hold paint much better than all competitive PVC trim product.

ü       To paint KOMA products, use standard exterior or interior latex paint.

ü       All you have to do is clean the surface and paint

ü       No special surface preparations are required prior to painting.

ü       Avoid painting KOMA surfaces dark colors (do not exceed # 65 on hue scale) in areas of direct sunlight.

ü       Use wood filler or latex caulk for plugging nail holes.

GLUING

ü       Standard PVC cements, or cellular PVC cements, provide a strong KOMA to KOMA bond.

ü       For best results, glue all KOMA joints to prevent joint separation.

ü       The KOMA glue joint should be secured long enough to allow adequate bonding time.

ü       When bonding KOMA to other surfaces, check with the adhesives label to see if it’s use is good for your purpose.

REPAIRING DAMAGED SURFACE

Auto body filler works well for large damaged areas.

MOLDING/MILLING

ü       KOMA products can be molded/milled using standard woodworking equipment.

MOISTURE

ü       KOMA products do not absorb moisture. KOMA products can be installed above or below grade.

EXPANSION & CONTRACTION

ü       KOMA trimboards are PVC and will expand and contract with changes in temperature.

ü       KOMA trimboard fastened along its entire length will minimize expansion and contraction.

ü       When installing KOMA trimboard allow 3/16” space per 18 foot of KOMA trimboard for expansion and contraction. Joints between pieces of KOMA should be glued to eliminate joint separation. See “Gluing” section above.

ü       When gaps are glued on a long run of KOMA, allow expansion and contraction space at ends of the run.

ü       A high quality polyurethane sealant is recommended for joints.

SPANNING

KOMA products are not to be used in load bearing applications.  Do not exceed 16” span. When applying edge and center bead, fasteners should be used every 16”.
