The Varathane premium gel stain is made for wood and non-wood surfaces. It is recommended to apply it on composite wood grain and raised panel doors. It can be used with plastic primer on planters, chairs, and more. Gel provides superior staining and colour control with twice the coverage of liquid stains. The thicker consistency prevents runs and drips, making it perfect for vertical surfaces. The stain is offered in grey in a 236 mL size and covered by a manufacturer warranty.
