Product Information

Full details

The Mylands Primer & Undercoat in Red is an essential preparation tool designed for professional decorators and DIY enthusiasts looking to achieve a superior finish on interior surfaces. Its key benefit lies in its high opacity and excellent adhesion properties, which create a stable foundation for water-based topcoats on new plaster or patch-repaired areas. While it offers a low-odour and user-friendly experience, users should note that it is specifically formulated for internal applications and requires thorough surface preparation to ensure optimal micro-porous performance.

Extended Product Information

FAQs

Can I use this on exterior walls?

No, this product is specifically formulated for internal applications only.

Is this primer suitable for new plaster?

Yes, its micro-porous nature makes it an excellent choice for preparing new, dry plaster.

Do I need to sand the surface before applying?

While not always mandatory, light sanding of rough or glossy patches helps achieve the best possible adhesion.

How should I clean my brushes after use?

Because it is a water-thinned primer, brushes can be cleaned easily with warm water and a mild soap.

Can I use this under oil-based paints?

This product is highly recommended for use under Mylands water-based finishes; compatibility with non-Mylands oil-based products should be tested on a small area first.

Does this primer need to be thinned?

The product is ready to use. If you are using a spray application method, please consult the technical data sheet for specific thinning ratios.

Troubleshooting

Primer feels patchy after drying

Ensure the surface was adequately cleaned and free of dust before application; consider a second thin coat if the surface is highly porous.

Difficulty in adhesion

Check that the existing surface is not oily or glossy. If glossy, lightly sand the area before applying the primer.

Stronger odour than expected

Ensure the room is well-ventilated during and after the application process.

Setup, Compatibility & Care

Before application, ensure the target surface is clean, dry, and free from grease or loose debris. For new plaster, allow sufficient drying time before priming. Stir the product thoroughly before use to ensure the pigments are properly dispersed. Cleanup is straightforward; wash tools immediately after use with warm, soapy water. Store the container in a cool, dry place away from extreme temperatures to maintain the consistency of the water-thinned formula for future use.
