Application Instructions:

1. Preparation: Ensure the MDF surface is clean, dry, and free from dust. Lightly sand the surface if necessary to remove rough edges.

3. Drying Time: Touch dry in approximately 30 minutes. Allow a minimum of 2 hours before applying paint or varnish. Drying times may vary with temperature and humidity.
4. Re-Coating: Typically, one coat is sufficient for most applications, but highly absorbent surfaces may require a second coat.
