Specifications

What it's used for

• Fitting to internal window reveals as a finished window sill in new builds and renovation projects
• Replacing damaged or worn timber window boards in kitchens and bathrooms where some moisture resistance is required
• Providing a consistent, paint-ready surface in social housing, student accommodation and commercial fit-outs where a uniform finish across multiple windows is needed
• Use alongside MDF skirting and architrave sets for a fully coordinated, knot-free interior finish

Fitting and handling

Allow the boards to acclimatise in the installation room for at least 24 hours before fixing, particularly in kitchens and bathrooms where temperature and humidity can vary. Fix using a suitable grab adhesive applied to the back face and underside bearing surface, ensuring full contact along the length to prevent any flex or movement once set. Once fitted, apply one or two coats of water-based eggshell or satinwood topcoat over the factory primer for a durable, washable finish, paying particular attention to any cut ends which should be sealed with primer before painting.

FAQ

Is this MDF window board suitable for use in bathrooms or kitchens?

Yes. The board is manufactured from moisture resistant MDF, which means it has improved resistance to humidity and occasional splashing compared with standard MDF. It is not waterproof, so cut ends and any fixings should be primed and sealed before painting to maintain that resistance over time.

Does the 225mm primed MDF window board need sanding before painting?

Very little preparation is needed. The two-coat factory primer gives a smooth, consistent base that is ready for a topcoat with a light key using fine-grade abrasive paper if preferred. Any cut ends will need a coat of primer before the topcoat is applied.

What adhesive should I use to fix an MDF window board?

A solvent-free grab adhesive, such as a no-nails type or a polymer-based construction adhesive, is the standard approach for a concealed, nail-free fix. Apply in beads along the bearing surface, press firmly into position and support until the adhesive has cured as directed by the manufacturer. Panel pins can also be used for additional security where access allows.
