Fixing and buying guide

What this door is and who it is for

The PREMDOR 4 Panel Smooth FD30 FireShield is an internal moulded panel door suitable for residential and commercial projects where fire performance is required. It is ideal for builders merchants customers who need to paint doors on-site rather than pre-finished options, reducing logistics complexity and allowing colour matching to site specifications. The smooth face finish ensures a professional appearance after painting. This door is PEFC compliant, confirming responsible timber sourcing.

Fire rating and building regulations

The FD30 designation indicates this door provides 30 minutes of fire resistance. This rating is relevant for certain building regulation applications, particularly in escape routes, communal areas, and specific commercial settings. Verify with your building control officer or architect whether FD30 performance is required for your project, as not all internal doors require fire rating. If fire performance is not needed, standard non-rated doors may offer cost savings.

Finishing and preparation

The door arrives with a white base coat applied to smooth moulded panel facings. This base coat is designed as a primer and foundation for on-site painting. Sand lightly with fine abrasive paper before applying your chosen topcoat to ensure good paint adhesion. The smooth face finish will accept paint evenly without the grain texture of solid timber doors. Allow adequate drying time between primer and topcoat, and follow paint manufacturer instructions for coverage and application.

• White base coat applied; ready for on-site painting
• Smooth faces accept paint finish evenly
• Light sanding recommended before topcoat application
• Allow proper drying time between coats
