FAQs
Can I use this on exterior MDF?
Yes, Rustins Quick Drying MDF Primer Sealer is suitable for both interior and exterior use. However, ensure the MDF is exterior grade and properly sealed with a suitable topcoat for outdoor applications.
How many coats do I need?
Generally, one coat is sufficient. However, very porous MDF may require a second coat. Allow the first coat to dry completely before applying the second.
What should I use to apply the primer sealer?
You can use a brush, roller, or spray. A brush is suitable for smaller areas, while a roller is better for larger surfaces. Spraying provides a smoother finish.
Can I use oil-based paints over this?
Yes, Rustins Quick Drying MDF Primer Sealer is compatible with most oil-based and water-based paints. Always test in an inconspicuous area first to ensure compatibility.
How long does it take to dry?
It is touch-dry in approximately 30 minutes and can be recoated after 2 hours.
What is the coverage?
Approximately 6m² per 500ml, providing a total coverage of about 12m² for the 1L tin.
Do I need to sand the MDF before applying the primer?
Light sanding is recommended if the MDF surface is rough or has any previous coatings. This improves adhesion.
Is this product suitable for use on children's toys?
Yes, it conforms to Toys Safety Regulations 1995, BS EN 71 Part 3, making it safe for use on children's toys.
Troubleshooting
Paint not adhering properly
Ensure the MDF surface was properly prepared (cleaned and lightly sanded). Ensure the primer sealer is fully dry before applying the topcoat. If issues persist, consider using a different topcoat.
Uneven finish
Avoid applying too much primer sealer in one go. Ensure even coverage. Lightly sand between coats if necessary. Consider the porosity of the MDF.
Primer sealer takes longer to dry
Ensure the application area is well-ventilated. Check the temperature and humidity levels. High humidity can slow down drying times.
