How to thin polyurethane?


Polyurethane comes in oil or water-based formulas. To thin oil-based polyurethane for any reason, you'll need paint thinner. If a desire to thin the polyurethane is for a lighter or more controlled finishing process, a mix of 1 part thinner to 2 parts polyurethane is recommended. For an even thinner coat, a 50-50 ratio can be incorporated. The same premise applies to water-based polyurethane, but water is used as the thinning agent. A word of caution for either formula is that polyurethane can vary by manufacturer, so add the thinning agent in batches to prevent permanently compromising the ratio.
