Product Information

Full details

The Mylands Plant-Based MS Primer & Undercoat is designed for DIY enthusiasts and professional decorators seeking a versatile, high-adhesion foundation for both interior and exterior projects. Its primary benefit is its exceptional multi-surface compatibility, allowing for a smooth, professional finish on everything from wood and metal to uPVC and masonry. While it offers excellent coverage and a low-odour profile, users should note that as a water-based formula, application conditions should be carefully monitored for proper curing times.

Troubleshooting

Primer is not adhering to a specific surface

Ensure the surface was sanded to remove any factory finish or gloss and is completely clean of oils or waxes.

Brush marks are visible in the dried coat

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

Slow drying time

Check the ambient humidity; move to a well-ventilated area to allow proper airflow to accelerate the water evaporation process.

Setup, Compatibility & Care

Before applying, ensure the surface is clean, dry, and free of grease or loose debris. For porous surfaces like plaster, a light sand and dust removal are recommended. If painting previously glossed surfaces, lightly sand the area to provide a mechanical key for the primer. Apply using a high-quality synthetic brush, roller, or spray equipment. Clean tools immediately after use with warm, soapy water. Store the container in a cool, dry place away from extreme frost or heat to maintain the shelf life of the product.
