Extended Product Information

FAQs

Can I use this on metal?

Yes, this primer is anti-corrosive and works well on metal surfaces.

Does it need to be thinned?

It is water-thinned, but typically applied as-is. Consult the product tin if you are using spray equipment.

Is this suitable for external use?

Yes, it is designed for both interior and exterior applications.

How long until I can apply the topcoat?

Thanks to its quick-drying formula, most surfaces are ready for a topcoat within a few hours, depending on room conditions.

Do I need to sand between coats?

Sanding is only required if you notice debris or want to achieve an ultra-smooth finish.

Can I use this on bare plaster?

Yes, it is highly recommended for preparing new, friable, or patch-repaired plaster.

Troubleshooting

The primer is not sticking to the surface

Ensure the surface was sanded, cleaned, and free from oil or grease prior to application.

Surface feels rough after priming

Lightly sand with fine-grit sandpaper between coats for a smoother final finish.

Slow drying time

Ensure the room is well-ventilated and the temperature is not below 10 degrees Celsius.

Setup, Compatibility & Care

Before application, ensure the substrate is clean, dry, and free from grease, wax, or loose debris. For glossy surfaces, a light sanding is recommended to improve mechanical keying. Apply using a high-quality synthetic brush, roller, or spray equipment. Clean all tools immediately after use with warm, soapy water. Store the container in a cool, dry place and ensure the lid is tightly sealed to prevent the water-based binder from skinning. This primer is fully compatible with Mylands Dead Matt, Eggshell, Satin, and Gloss interior finishes.
