For the perfect finish

Form meets function at every angle with HardieTrim® boards and finishing. Accentuate corners, columns, friezes, doors and windows, and add that final accent to your design statement.

Wooden trim is an easy target: weather ravages it, water warps it and before long, wood trim will crack, peel and need sanding and repainting or even replacing. HardieTrim boards, made from the same high-performance fibre cement as all of our products, and Hardie MetalTrim™ are designed to work together with HardiePlank®, HardiePanel® and HardieLinea® to give a low-maintenance, weather resistant and perfect finish.

Product faq

How do I cut HardiePlank® cladding and how can I control the dust?

We sell a range of specialist tools designed to cut our products quickly, effectively and with a minimum of dust. The best are hand tools like the HardieGuillotine™ which is available from your distributor. Always use approved safety glasses and appropriate EN approved respiratory protection (PPE #2 or #3) for particulate hazards when working with HardiePlank® cladding and HardieTrim® NT3™.

How can I repaint HardiePlank® planks and HardieTrim® NT3™ profiles?

Specification for repainting HardiePlank® planks and HardieTrim® NT3™ profiles:

1. Abrade entire area with a Scotch Brite pad or similar (not sandpaper) to flat off the shine on the existing planks and trims. It is not necessary to abrade off the existing paint, just the shine to provide a key.
2. Wash down the elevations using a garden hose from top to bottom to remove all traces of atmospheric dirt, loose paint and dust. Do not use a pressure washer as this may damage the ColorPlus® coating
3. Allow to dry thoroughly. This will depend upon the weather conditions, but often a minimum of 24 hours.
4. Apply one coat of paint with a brush along the long face of the product taking care to brush the paint well into the surface. Do not overload the brush or allow the paint to run. Do not try to cover the existing color in one coat. Paint must be applied when the weather is dry and the air temperature is above 5°C and will remain so for the rest of the day. Paint coverage is approx. 10m²/litre per coat.
5. Allow the first coat to dry for 2-3 hours (2 hours min; 4 hours max).
6. Apply second coat of paint as above before the first coat is fully cured. Note: This point is very important as the paint performance is dependent upon film weight. The two coats have to bond to each other and so the first coat must not be fully cured when the second coat is applied. It is better to do one area at a time completely rather than the whole thing one day and the second coat the next.
Any self-applied coating is not covered by our warranty.
