FAQs

Can I use this primer on exterior walls?

Does the red tint affect my light-colored topcoat?

When used correctly under high-quality topcoats, the tint acts as a foundation. However, always test on a small area if you are concerned about color bleed-through.

Do I need to sand the wall before applying this primer?

Light sanding of existing glossy surfaces is recommended to improve mechanical adhesion.

Is this primer safe for use in bedrooms?

Yes, its low-odor, water-thinned formula makes it suitable for use in living spaces and bedrooms.

How long should I wait before painting over the primer?

Drying times can vary based on humidity and temperature, but typically it should be touch dry before applying a topcoat. Check the product label for specific recoat times.

What is the best way to clean my brushes?

Since it is a water-thinned product, clean your tools thoroughly with warm soapy water immediately after use.

Troubleshooting

Primer feels patchy after drying

The surface may have been too porous. Apply a second thin coat to ensure an even foundation.

Poor adhesion to the wall

Ensure all dust, grease, and loose debris are removed from the surface before the initial application.

Primer drying too quickly

Working in direct sunlight or high heat can cause premature drying. Try to maintain a stable room temperature during application.

Setup, Compatibility & Care

Before application, ensure the substrate is clean, dry, and free from dust or grease. If the surface is friable (crumbly), scrape away loose material and prime the area thoroughly. This product is specifically formulated to be compatible with Mylands water-based interior finishes, which are recommended for the best results. Apply using a brush, roller, or spray equipment. For maintenance, ensure the lid is tightly sealed after use to prevent drying, and store in a cool, dry place away from extreme temperatures. Clean brushes and rollers with warm, soapy water immediately after application to prevent the primer from hardening on the bristles.
