MDF surfaces can be highly absorbent, particularly on cut edges. This specialist primer undercoat helps seal and stabilise MDF, reducing fibre raise and promoting a consistent, uniform finish when overcoated.
It is particularly suited to new MDF doors, skirting boards, shelving and fitted furniture.
The quick-dry formula allows for faster recoating compared to traditional solvent-based systems, helping decorators complete jobs more efficiently. Its low odour, water-based composition also makes it suitable for use in occupied properties and enclosed interior spaces.
Recommended for interior use on:
MDF doors and frames
Skirting boards and architraves
Built-in wardrobes and cabinets
Interior timber joinery
Shelving and furniture
For best results, follow with a compatible Dulux Trade water-based satin, eggshell or gloss finish.
Ensure surfaces are clean, dry and free from dust before application. Lightly abrade smooth MDF surfaces where necessary. Apply evenly with a synthetic brush or roller. Allow to dry fully before lightly sanding and applying finishing coats.
Offering excellent adhesion, fast drying performance and reliable sealing for MDF and interior timber, this 2.5L pack is ideal for medium-sized projects. It provides a professional-quality foundation that supports smooth, durable topcoat finishes while improving on-site efficiency.
