Yes — for doors, proper surface preparation is essential before applying a fresh coat of paint, and that means removing the old paint first.
The Recommended Process
Step 1: Strip the old paint
Scrape off all existing paint from the door surface thoroughly. Skipping this step can result in poor adhesion, an uneven finish, and a paint job that peels or chips far sooner than it should.
Step 2: Clean the surface
Once the old paint has been removed, clean the surface to ensure it is free from dust, grease, and any other residues. Paint bonds far better to a clean, bare surface.
Step 3: Apply Aqua Primer Sealer Undercoat
Apply 1 to 2 coats of Nippon Paint Aqua Primer Sealer Undercoat, depending on the condition of the surface. This one-step pre-coat is quick-drying and helps the topcoat adhere properly, ensuring a smoother and more durable finish.
Step 4: Apply Aqua Bodelac topcoat
Once the primer is fully dry, apply 2 coats of Nippon Paint Aqua Bodelac in your chosen colour. Aqua Bodelac is a water-based modified acrylic gloss enamel specifically formulated for interior wood and metal surfaces such as doors and window frames. It is low-odour, low-VOC, and Singapore Green Label certified — an eco-friendly alternative to conventional solvent-based paints that is just as durable.
Why Water-Based?
The painting system recommended here is entirely water-based, making it easier to apply, quicker to dry, and simpler to clean up. Tools can be washed with water immediately after use — no solvents required.
