FAQs

Can I use this on bare metal?

Yes, it has anti-corrosive properties, making it suitable for metal provided the surface is clean and free of rust.

Do I need to sand the surface before applying?

For previously painted or non-porous surfaces like plastic or uPVC, a light sanding is recommended to improve adhesion.

Is this primer suitable for exterior use?

Yes, the formulation is designed to be durable enough for both interior and exterior environments.

What topcoats are compatible with this primer?

It is designed to be used under Mylands Plant-Based Paint in Dead Matt, Eggshell, Satin, or Gloss.

How do I clean my brushes after use?

Because it is a water-based product, you can clean your brushes and tools with warm, soapy water.

Can this be applied to new plaster?

Yes, it is highly recommended as a sealer for new plaster surfaces.

Troubleshooting

Primer is not sticking to the surface

Ensure the surface was thoroughly cleaned of grease or oil and lightly sanded if it was previously glossy.

Surface feels rough after drying

This may be due to 'nibs' or dust; lightly sand the primer with fine-grit sandpaper and wipe clean before applying the topcoat.

Longer than expected drying time

Avoid painting in high humidity or very cold temperatures, as these conditions significantly slow down the water evaporation process.

Setup, Compatibility & Care

Before application, ensure all surfaces are clean, dry, and free from loose paint, grease, or dust. For glossy or non-porous surfaces, a light sanding will improve the mechanical bond.

After use, clean brushes and equipment with warm, soapy water while the product is still wet.
