Seal In All The Beauty.

This high-solid primer excels at sealing cork, dry and absorbent woods, and large surfaces such as old dried out  softwood floors and architectural woodwork. We also recommend its use for sealing beams, wood surfaces on boats, and masonry such as stone, slate, and brick. Use it as a primer on highly absorbent surfaces for BioShield products #4,  #32.

Ingredients: Clarified Linseed Oil, Lead-Free Dryers (Zircon, Cobalt Octoat), and Essential Oils.
