Painting of external and internal door leaves

March 11, 2019

Do the top and bottom of external and internal door leaves need to be painted? This is a common question asked by our members and the answer is yes – the leaves of external and internal doors are required to be sealed or painted.

Timber is a product that is greatly affected by changes in moisture. The change in moisture can lead to timber doors warping, swelling and jamming. The simple act of sealing or painting the edges of the door leaves helps to combat moisture absorption in the doors and the need to either replace the doors or come back time and time again to refit the doors.

This applies to newly hung doors as well as doors that have been altered or refitted due to movement, binding or refitting after an alteration or renovation of an existing house. The entire door should be painted immediately after fitting and before hanging; this includes behind the hinges and lock, and most importantly, the top and bottom edges.

The Guide to Standard and Tolerance 2015 Part 8.06, deemed it a defect if the door leaves are not sealed/painted on all sides, top and bottom edges in accordance with the manufactures instructions. In most cases the manufacturer requires the top and bottom of the doors to receive the same number of coats of paint as the door face.

The Standard and Tolerance Guide also provides a paint durability table that outlines the minimum durability time allowed for painted coatings whether acrylic or enamel. This is a useful guide when deciding if there might be a defect associated with the paint work.

Note: the standards for painting must be either in accordance with the manufacturers installation requirements or AS/NZ 2311. 2009 Guide to painting of buildings.
