FAQs

Is this paint suitable for kitchens and bathrooms?

While it is a durable emulsion, it is designed for general interior walls. For high-humidity areas, a specialized bathroom or kitchen paint with anti-mould properties is typically recommended.

Do I need a primer for this paint?

If you are painting over sound, previously painted walls, a primer is not strictly necessary. However, for new or porous plaster, a mist coat is required.

How many coats are usually required?

Due to its high opacity, two coats are generally sufficient to achieve a full, even finish on most surfaces.

How do I clean my painting tools?

Because this is a water-based paint, simply wash your brushes and rollers thoroughly with warm, soapy water immediately after use.

What kind of undertone does Vintage Denim have?

Vintage Denim is a deep, muted navy blue with a distinct cornflower blue undertone.

Can this paint be used on woodwork?

No, this is formulated specifically for interior walls and ceilings. Use a dedicated trim or wood paint for doors, skirting boards, and frames.

Troubleshooting

Visible roller marks or patchy finish

Ensure you are applying enough paint to the roller and maintaining a wet edge while working across the wall.

Paint peeling shortly after application

Check that the surface was properly cleaned and free of grease or dust before painting; ensure no moisture was trapped underneath.

Flash rusting or discoloration

Ensure that the wall substrate is fully sealed, especially on new plaster, using a suitable primer or mist coat.

Pros and Cons

Pros

  • Sophisticated Vintage Denim dark navy aesthetic
  • Easy cleanup due to water-based formulation
  • High opacity for efficient coverage
  • Low VOC levels for better indoor air quality

Cons

  • Matt finish can highlight deep wall imperfections if not prepared well
  • Requires careful surface preparation for best results
  • Limited to interior use only

Setup, Compatibility & Care

Ensure that all surfaces are clean, dry, and free from loose or flaking material before starting. If the wall is new plaster, it is essential to apply a mist coat or appropriate primer first to prevent the substrate from soaking up the paint too quickly. During application, maintain a consistent "wet edge" to avoid roller marks. For care, avoid using abrasive scrubbing pads on the finished surface; a damp, soft cloth is usually sufficient for cleaning minor scuffs or dirt from the washable matt surface.
