Murdoch’s Hard Sealer


Murdoch’s Hard Sealer is our most versatile finish.
It’s used as a primer for our Murdoch’s Hard Oil, Table Top, & Uralkyd 500 Floor Finish topcoats or as a stand-alone finish with sheens ranging from satin to gloss, depending on number of coats applied. The combination of urethane alkyd, Polymerized Tung Oil, and a blend of our petroleum based & Di-Citrusol solvents enhance grain definition in the wood and offers a durable, beautiful finish.

Product Description

Murdoch’s Hard Sealer can be used as a standalone finish for a variety of projects. The Hard Sealer penetrates deep in the wood pore to deliver the Polymerized Tung Oil which provides beautiful grain definition and fills the wood pore. It has the flexibility of being used as a brush-on surface finish or can be hand-wiped to lower the sheen.
