FAQs

Can I use this primer under an oil-based paint?

This product is specifically recommended for use under Mylands water-based finishes and is generally not designed for oil-based systems.

Is this primer suitable for exterior use?

No, this product is strictly formulated for internal applications.

How long does it take to dry?

Drying times vary based on ambient temperature and humidity, but it typically becomes touch-dry within a few hours.

Do I need to sand the surface before applying?

While not always necessary on perfect plaster, lightly sanding existing finishes improves adhesion and helps ensure a professional result.

Can this be applied to fresh plaster?

Yes, it is suitable for new plaster, provided the plaster has been allowed to dry fully according to the plaster manufacturer's guidelines.

Troubleshooting

Poor adhesion to the substrate

Ensure the surface was thoroughly cleaned of dust, grease, and loose debris before painting.

Primer shows streaks after drying

Ensure even application by cross-rolling and avoid over-working the product once it begins to set.

Pros and Cons

  • Environmentally friendly low-odor composition
  • Versatile application on diverse interior surfaces

Cons

  • Not intended for use as a standalone final finish

Setup, Compatibility & Care

Preparation is key: ensure the wall is sound and free from loose material. If the surface is particularly porous, a mist coat may be required. The primer is compatible with brushes, rollers, or spray equipment. Clean all tools immediately after use with soap and warm water. Store the container in a cool, dry place, ensuring the lid is tightly sealed to prevent the product from drying out or skinning over. Avoid applying in temperatures below 10°C or in conditions of high humidity to ensure proper curing.
