Why would you?
Assuming you're talking about wood finishing, spar urethane can be used over a water sealer. In fact, the combination is better than just a sealant or just the spar urethane. A very durable finish for outdoor wood products is soaking the unfinished wood with boiled linseed oil, letting the linseed oil cure, removing excess cured linseed oil, then applying spar urethane.
Look at label on can if urethane is oil based it should be fine. Think of it like basic chemistry. Oil and water dont mix, xlene based products are used to strip oil, so if ur using a xlene base over oil thats a no brainer. The urethane I use is a xlene base so I wld never use over oil. Im just not sure if they sell a oilbased urethane so check the labels
Only if the urethane paint is not waterbased... Urethane Paint cannot be mixed with anything except other Urethane products. Urethane Paints do not work on the same principals as "oil based" paints. Oil Based Paints rely on evaporation to dry. Urethane cures. by chemical reaction.
cedar can be preserved by painting or using an oil finish. Some finishes have a UV protector for outdoor use to stop discoloration. the type of finish depends on the look desired, if you want to see the wood then use an oil or spar urethane.
Thinner--specifically, mineral spirits. Reducer is used in urethane car paint.

Yes, urethane is oil-based. Oil-based urethane typically has a longer drying time and provides a more durable finish compared to water-based urethane. Water-based urethane dries faster, has less odor, and is easier to clean up.

Oil-based urethane provides a durable and long-lasting finish for wood projects. It offers excellent protection against moisture, scratches, and wear, enhancing the overall appearance and longevity of the wood. Additionally, oil-based urethane is easy to apply and provides a smooth, glossy finish that enhances the natural beauty of the wood.
Urethane, also known as ethyl carbamate, is a chemical compound that can be produced synthetically or be found naturally in fermented foods and alcoholic beverages. Industrially, urethane is commonly produced as a byproduct in the production of ethyl carbamate-based chemicals.

When you apply urethane enamel over an oil-based primer, it can create adhesion issues due to the differing chemical compositions and drying times. The urethane may not bond properly, leading to peeling, cracking, or bubbling over time. To ensure a successful application, it's recommended to sand the oil-based primer lightly and use a compatible primer if necessary. Always check the manufacturer's guidelines for compatibility to achieve the best results.
Lacquer thinner will thin many types of oil based paint, but not all. -Experiment with a little first.
Normally there is no need to thin oil based paint if you are applying it with a brush. If the oil based paint is old, it may have thickened over time and in that case you can thin it until it is at a consistancy which is easy to brush and gives good coverage. If you are spraying the paint you may want to thin it so it sprays easier from the gun. Thin then test and do it agoin until it sprays evenly from the gun. Normall "oil based" paints when thinned are with paint thinner. However always read the label on the paint for any instructions concerning thinning.
if it is water based, then water, if it is oil based, mineral spirits
