What this product is and who it is for
This is a large-format decorative moulding manufactured from moisture-resistant MDF with a factory-applied primer. It is designed for trade and serious DIY customers installing skirting boards, dado rails, or architectural features in kitchens, bathrooms, cloakrooms, and other moisture-prone internal spaces. The pre-primed finish saves preparation time and provides a stable base for paint or stain. It is not suitable for external use or areas of prolonged water immersion.
- Pre-primed MDF profile ready for paint or stain
- Moisture-resistant core for kitchens and bathrooms
- Large 198mm face width for statement moulding
- Internal use only
Sizing and pack contents
Each length is a single 5.49 metre continuous piece. The profile measures 18mm deep and 198mm across the face. Calculate your linear metre requirement by measuring the perimeter of the room or the length of wall where the moulding will be installed, then add 10 per cent for waste, joints, and cutting errors. Order additional lengths as required; joints should be cut at 45-degree angles for a professional finish.
- Single 5.49 metre length per item
- Face width 198mm, depth 18mm
- Pre-primed finish
- Add 10% to measured length for waste and joints
Compatibility and fixing
This moulding is compatible with standard timber fixings and adhesives suitable for MDF. Fix to plasterboard, brick, or timber substrates using MDF-grade screws, nails, or construction adhesive rated for MDF. Ensure the wall surface is clean, dry, and level before installation. In moisture-prone areas, use corrosion-resistant fixings and allow the primer to cure fully before exposing to steam or splashing. The moisture-resistant core extends durability but does not make the product waterproof.

Pre-installation checks
Before ordering, verify your wall dimensions and check that the wall surface is sound, dry, and free from mould or damp. Inspect the profile on delivery for damage or warping. Store the moulding flat in a dry environment for at least 48 hours before installation to allow it to acclimatise. Check that your fixings and adhesives are rated for MDF use. Allow the primer to cure fully before painting or staining, following the primer manufacturer's instructions.
