FAQs

Is this paint suitable for kitchens or bathrooms?

While it is durable, Johnstones Covaplus Vinyl Matt is primarily for general interior walls. For areas with high steam or heavy condensation, consider a dedicated moisture-resistant paint.

How long does it take to dry?

Under normal conditions, it is touch dry within 1-2 hours and ready for a second coat after 4 hours.

Can I use this on radiators?

No, this product is designed for walls and ceilings. You should use a paint specifically formulated for metal and high-heat surfaces for radiators.

Does Chapel Stone look more grey or purple?

It is a greige (grey-beige) colour. The mauve undertones give it warmth, making it look more complex and inviting than a standard 'cold' grey.

How do I clean my brushes?

Because it is water-based, simply wash brushes and rollers thoroughly in warm, soapy water immediately after use.

Troubleshooting

Visible roller marks after drying

Ensure you are maintaining a 'wet edge' during application and avoid over-working the paint once it begins to tack up.

Paint is peeling or flaking

This often indicates a dusty or greasy substrate. Ensure surfaces are properly cleaned and primed before re-application.

Coverage seems thin or streaky

Apply a second coat once the first is completely dry. If the wall was very porous, apply a dedicated primer-sealer first.

Pros and Cons

Pros

  • Excellent opacity and coverage for a professional look
  • Sophisticated, modern greige colour palette
  • Quick drying time for faster project completion
  • Low odour formula suitable for interior spaces
  • Easy to clean surface once fully cured

Cons

  • Matt finish can be less stain-resistant than glossier alternatives
  • May require extra care during cleaning to avoid burnishing
  • Limited to interior use only

Setup, Compatibility & Care

Before starting, ensure surfaces are clean, dry, and free from dust or grease. If painting onto fresh plaster, apply a mist coat first to prevent the paint from soaking in unevenly.

  • Application: Use a synthetic bristle brush for cutting in and a medium-pile roller for large surfaces.
  • Compatibility: Suitable for use on primed wood, plaster, and common interior masonry surfaces.
  • Care: Allow the paint to fully cure for several days before attempting to wash. When cleaning, use a soft, damp cloth with mild detergent, avoiding abrasive sponges that could burnish the matt surface.
