FAQs
What surfaces can I use this primer on?
Johnstone's Trade MDF Primer is specifically designed for use on MDF and other wood surfaces.
How many coats of primer do I need?
One or two coats are usually sufficient, depending on the porosity of the substrate. For highly absorbent surfaces, two coats are recommended.
Can I use this primer outdoors?
This primer is primarily intended for interior use. For exterior applications, consider a primer specifically designed for outdoor conditions.
What type of topcoats can I use with this primer?
This primer is compatible with a wide range of water-based and solvent-based topcoats. Always check the topcoat manufacturer's guidelines for compatibility.
How long should I wait before applying the topcoat?
Refer to the product label for the recommended drying time. Allow the primer to fully dry before applying the topcoat to ensure proper adhesion and a durable finish.
How do I clean up after using this primer?
Clean brushes, rollers, and equipment with water immediately after use.
Is this primer environmentally friendly?
Yes, it is a water-based, low-VOC formula, making it a more environmentally friendly option compared to traditional solvent-based primers.
Troubleshooting
Primer is not adhering properly.
Ensure the surface is clean and properly prepared. Sand the surface lightly to improve adhesion. Apply a second coat if needed, ensuring adequate drying time between coats.
Primer takes longer to dry than expected.
Ensure proper ventilation and check the room temperature and humidity levels. High humidity can slow drying times.
Primer odour is strong.
While low-odour, ensure adequate ventilation during application. If the odour persists, check the product's expiry date and storage conditions.
Uneven finish after priming.
Apply the primer evenly, avoiding excessive build-up. Use a quality brush or roller and ensure the product is properly mixed. Consider sanding lightly after the first coat, if necessary.
