Guide to Use

Guide to Use: Apply as a first primer or over acrylic-primed surfaces. Suitable for MDF or other lightly sanded supports to improve adhesion. No size or PVA is required beneath. Apply 1-3 coats using a brush or roller, either undiluted or diluted with up to 20% water to adjust texture and handling. Allow a minimum of 30 minutes drying between coats, though 24 hours is recommended for best results and stability. Do not apply over rabbit skin glue, oil primers, oil paint, or wide weft canvas.
