Product Information

Full details

The Mylands Plant Based Multi-Surface Primer & Undercoat is designed for DIY enthusiasts and professionals seeking a versatile, high-performance base coat for a wide variety of interior and exterior materials. Its primary strength lies in its exceptional multi-substrate adhesion and quick-drying, low-odor formulation, making it an ideal choice for refreshing furniture, metal, or masonry. However, users should be aware that while it is highly resilient, it is specifically optimized for use under Mylands water-based finishes, and optimal results depend heavily on proper surface preparation.

FAQs

Can I use this on outdoor metal?

Yes, it contains anti-corrosive properties that make it suitable for interior and exterior metal surfaces.

Does this primer require a topcoat?

Yes, this is an undercoat/primer meant to be finished with a topcoat like Mylands Dead Matt, Eggshell, Satin, or Gloss.

Is it safe to use indoors?

Yes, its low-odor, water-based formulation makes it safe and convenient for indoor projects.

Do I need to sand the surface before applying?

Lightly sanding glossy or very smooth surfaces is recommended to improve mechanical adhesion.

What should I use to clean my brushes?

Because it is water-based, simply wash your brushes and rollers with warm, soapy water.

Can I use this on new plaster?

Yes, it is suitable for preparing new plaster, provided the surface has been allowed to dry fully and is properly prepared.

Troubleshooting

Poor adhesion to the surface

Ensure the surface was thoroughly cleaned of all grease and contaminants; light sanding may be required to provide a better profile for the primer.

Visible brush marks or streaks

Use a high-quality synthetic brush or a fine-nap mohair roller and ensure you are not over-working the paint as it begins to set.

Slow drying times

Ensure the working area is well-ventilated and the ambient temperature is above 10 degrees Celsius; avoid applying in high humidity.

Setup, Compatibility & Care

Before application, ensure the surface is thoroughly cleaned and sanded if necessary to provide a mechanical key. The product can be applied via brush, roller, or spray depending on the size of the project. It is specifically designed to be compatible with Mylands Plant-Based Paint lines including Dead Matt, Eggshell, Satin, and Gloss.

For care and maintenance, store the container in a cool, dry place away from extreme temperatures to prevent the water-based binder from degrading. Once finished, tools can be cleaned easily using warm soapy water while the primer is still wet. For long-term protection of the painted finish, avoid using harsh abrasive cleaners on the final cured surface.
